Infonetics Surveys: Perceived top NA Cloud Service Providers; Google, IBM, Amazon lead in various categories

1.  Infonetics Research released excerpts from its 2014 Cloud Service Strategies: North American Enterprise Survey, which explores businesses’ plans for the adoption and usage of cloud services.

Infonetics survey respondents rated Microsoft, IBM, Amazon, Google and Cisco top cloud service providers (CSPs). Note that those companies are perceived as the top CSPs, independent of their actual market share, revenue or profits derived from delivering cloud services.

Infonetics asked survey respondence somewhat of an open-ended  question:  “Whom do you consider to be the top 3 cloud service providers?”

Marketing Director Kim Peinado explains, “We ask this question in a lot of our surveys, because it provides a good view of overall brand strength. Typically, the larger the provider (e.g., broad product portfolio) and the more visible their brand, the better they fare in this question.”

From the report: “The majority of the CSPs named by respondents as top three cloud providers have a long history as a software vendor and professional services provider or were a very early entrant into the off-premises cloud services market. Cisco is the one exception, having been able to leverage its dominant position in networking and communications to launch a Web collaboration offering with significant market recognition.”


CLOUD SERVICE SURVEY HIGHLIGHTS:

. When asked whom they consider to be the top cloud service providers (CSPs), Infonetics’ survey participants most often named Microsoft, IBM, Amazon, Google and Cisco
. Factors driving enterprise respondents’ adoption of off-premises cloud include increased performance, agility, scalability, and reduced costs
. Cloud-as-a-service (CaaS) adoption grows through 2016, while infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS) decline
o CaaS appeals to businesses because it is an automated and pre-configured application execution environment operated on their behalf by a CSP
. The cloud spells disruption and opportunity for network equipment vendors: Respondents believe that shifting to the cloud will make it necessary to consider alternate vendors and demand better LAN and WAN performance
. For over 3/4 of businesses surveyed, a CSP’s security reputation is a critical factor in the vendor selection process

 

“Our latest cloud strategies study shows that hybrid cloud will see a significant increase in adoption over the next two years, growing from 30% of respondent enterprises today to 46% by 2016,” notes Cliff Grossner, Ph.D., directing analyst for data center, cloud, and SDN at Infonetics Research. 

Grossner continues: “This is driving a new architecture for the data center with virtualized servers, storage, and networks where applications are automatically deployed by data center orchestration software.”


CLOUD SURVEY SYNOPSIS:

For its 29-page annual cloud service strategies survey, Infonetics interviewed qualified IT decision-makers with detailed knowledge of and influence in their organizations’ cloud service plans and purchase decisions at 155 North American enterprises. Survey participants were asked about their current usage of and plans for deploying cloud services, including IaaS, CaaS, PaaS, SaaS deployment drivers and barriers, uses, technologies, and architectures (public, private, community, hybrid), as well as their opinions of cloud service providers (CSPs).


2.  Infonetics Research released excerpts from its new Cloud Services for IT Infrastructure and Applications market size, market share, and forecasts report, which tracks the off-premises cloud services market and the vendors who play in this space. 

The new 18-page cloud services report provides detailed analysis of the off-premises cloud services market, which consists of applications and computing infrastructure delivered from a cloud service provider’s (CSP) data center, including infrastructure as a service (IaaS), cloud as a service (CaaS), platform as a service (PaaS), and software as a service (SaaS).

CLOUD SERVICES MARKET HIGHLIGHTS:


. Software as a service (SaaS) represents more than 2/5 of all off-premise cloud service revenue out to 2018
. North America is where off-premise cloud services started, and it will remain the lead market through at least 2018
. Google is the market share leader for CaaS and PaaS, IBM is #1 for SaaS, and Amazon is tops in IaaS

“We continue to see new tools to automate data centers and technology for developers appear in the market, driving innovation around cloud as a service (CaaS) and platform as a service (PaaS), the revenue growth engines for off-premises cloud services,” notes Cliff Grossner, Ph.D., directing analyst for data center, cloud, and SDN at Infonetics Research.

Grossner adds: “The move to hybrid cloud architectures fuels the adoption of CaaS as enterprises migrate their on-premises data centers to a cloud architecture, where servers, storage, and networks are virtualized and applications are automatically deployed by data center orchestration software.”

Alan’s Issues & Questions related to Cloud Services and Networking:

1.  With all the price wars, especially for public cloud, which CSPs (if any) or making money?  That’s not generally reported by the companies in this market!

2. Access bandwidth- many cloud computing/storage apps will require fiber to the building- not bonded copper (n x DSL or n x T1 or T3). 

3. What networking technology to be used to get to/from the cloud service provider (CSP): public Internet, customer’s existing IP-VPN, CSP’s VPN, dedicated private line, Ethernet private line, etc. AT&T proposes to extend it’s IP-VPN sold to enterprise customers by providing access to CSP partners.  Here’s the article on that:
4. Mobile access will present a huge problem for CSPs.  Bandwidth Guarantees, QoS/SLAs, Roaming, and Security are important issues that need to be resolved.

Highlights of Infonetics’ Carrier SDN and NFV Hardware and Software market size and forecast report

Infonetics’ first-ever Carrier SDN and NFV Hardware and Software market size and forecast report, led by Chief Analyst & Infonetics Co-founder Michael Howard. has just been released.  Tthe report tracks network functions virtualization (NFV) and software-defined networking (SDN) hardware and software used in service provider networks.  It complements a Sept 2014 Infonetics report on SDN for different market segments –Data Center and Enterprise SDN Hardware and Software.

The new 46-page report provides detailed analysis of the SDN and NFV markets and their many facets-from SDN router and switch hardware and software, to the many categories of NFV, particularly the virtualized network functions (VNFs) comprising policy (policy and charging rules function [PCRF] and deep packet inspection [DPI]), the mobile packet core and evolved packet core (EPC), IP multimedia subsystem (IMS), and security. To buy the report, contact Infonetics.

NFV AND SDN MARKET HIGHLIGHTS:
. NFV represents the lion’s share of the combined SDN and NFV market, from 2014 out to 2018
. The value of NFV is in the virtualized network functions software-the applications-rather than the orchestration and control; VNF makes up over 90% of the NFV software segment
. SDN and NFV exemplify the telecom industry’s shift from hardware to software: SDN and NFV software are projected to make up of three-quarters of total SDN/NFV revenue in 2018

“For three years, the telecom industry has been abuzz over SDN and NFV, with anticipation and hard work developing the vision, goals, architectures, use cases, proof-of-concept projects, field trials, and even some commercial deployments. We’ve been gathering data in this early market for nearly two years and are projecting the global service provider SDN and NFV market to reach $11 billion in 2018,” says Michael Howard, Infonetics Research’s co-founder and principal analyst for carrier networks.

To better understand spending in this emerging market, Infonetics classifies SDN and NFV hardware and software in three distinct categories:

  • First, revenue from brand new SDN and NFV software, which we expect to make up 20% of the total SDN and NFV market in 2018.
  • Second, revenue that comes from products that companies will buy instead of buying something else-what we refer to as ‘displaced’ revenue, including NFV infrastructure (NFVI) hardware (servers, storage, switches) purchased instead of network hardware (routers, DPI, firewalls, etc.). This segment will make up about 12% of the market in 2018.
  • Third, revenue that comes from newly identified segments of existing markets: mostly the virtualized network functions (VNFs), and also ports on routers, switches, and optical gear that have become SDN capable. This last segment makes up the largest slice of the SDN and NFV pie, 68% in 2018.

“This forecast took a ton of work to get to and involved a lot of our analysts. Hopefully it provides useful data for the industry,” said Kim Peinado, Infonetics’ VP of Marketing (and the single best Marketing Communications professional this author has ever worked with in 42 years of tech writing.

Mobile Network Operators to deploy more small cells, but backhaul challenges remain

There’s no doubt that mobile network operators (MNOs) need more capacity at a lower total cost of ownership.  New backhaul technologies are being considered, and some analysts predict $30 billion will be spent on backhaul equipment between now and 2017. However, with the explosion in demand for wireless bandwidth, which could reach 11.2 exabytes per month by 2017, there will be more small cell installations (to expand capacity due to frequency re-use in each small cell)ne, especially in hard-to-wire locations. These small cell extensions allow carriers to add capacity or coverage in a more targeted manner. However, the design and implementation of the backhaul and fronthaul can be even more complex than a traditional macro site.

“Operators participating in our small cell backhaul survey have yet to scale their small cell deployments, but they are looking to place over 20% of their traffic from the macro network onto small cells by 2018,” notes Richard Webb, directing analyst for mobile backhaul and small cells at Infonetics Research. “But they also tell us that backhaul-specific challenges like planning site acquisition, power and connection sourcing, and cost models have impacted deployment timelines.”

Infonetics Research released excerpts from its 2014 Small Cell Backhaul Strategies: Global Service Provider Survey, which provides insights into operator plans for small cell backhaul.

Infoneticcs-SMALL CELL BACKHAUL SURVEY HIGHLIGHTS:

  • Ethernet over fiber is survey respondents’ preferred backhaul technology for outdoor small cells, followed bypoint-to-point microwave and millimeter wave
  • Ethernet over fiber is the most-used technology for in-building deployments
  • With small cell deployments occurring in a range of locations and with an array of topologies, no single backhaul technology will be a universal solution
  • Likewise, no single vendor is likely to dominate the small cell backhaul landscape; it is still early days, but so far survey participants strongly favor a group of vendors with wired and wireless backhaul solutions
  • Respondent operators rate price-to-performance ratio, product reliability, and pricing as the top 3 criteria for choosing a small cell backhaul vendor

 

                               

 

SMALL CELL SURVEY SYNOPSIS:

For its 34-page small cell backhaul survey, Infonetics interviewed purchase decision makers at 25 incumbent, mobile, competitive, and cable operators from Europe, the Middle East and Africa, Asia Pacific, the Caribbean and Latin America, and North America about their current and future plans for small cell backhaul. The study provides insights into mobile traffic handling, specific backhaul issues related to in-building and outdoor small cells, and vendor preferences. The operators participating in the study control 29% of the world’s telecom capex.

Ron Mundry, CEO & Founder of Tower Cloud wrote in a Light Reading blog:  

To accommodate increasing bandwidth demand, carriers such as Verizon Wireless are deploying more small cells, and sites are becoming smaller, simpler and denser. According to SNS Research, the global market for 3G and 4G plateaued in 2013 at $52 billion, and is expected to drop by 2% annually, falling to $47 billion by 2020. Carriers are shifting spending to heterogeneous networking (HetNet), including small cell, carrier WiFi, distributed antenna systems (DAS) and cloud RAN (C-RAN) hardware. The small cell and carrier WiFi market alone should reach $4 billion in 2015. Mobile network operators are gearing up for a new kind of backhaul architecture that makes better use of the fronthaul radio access network.

The old access/aggregation/core hierarchy model — where data is collected at a base station and backhauled to aggregation points — no longer works in overloaded wireless networks, especially in dense urban areas. Subscribers armed with smartphones and tablets with video capability are putting a strain on the edges of the network, and mobile operators are now using macro cells to extend network access. The result is an evolution in small cell and macro cell applications, and the adoption of new HetNet architectural models to deliver voice and data.

Of course, there are challenges with small cell fronthaul networks. Carriers have to transmit data from both high-power and low-power RRHs to the BBUs, and using small cells can introduce high levels of cell edge interference. There also may be difficulties interfacing with existing macro networks.

And both RRHs and BBUs have to overcome real-estate restrictions. You have to have access rights and power at the RRH from a streetlamp or other street furniture. The BBU has to be optimally placed in relation to the RRH units, and it has to be accessible for maintenance — a combination of an engineering and a real-estate challenge. You also want to make fiber connections from the base station to the RRH and the antenna wherever possible, although wireless fronthaul and backhaul designs are evolving for cell sites deployed along roadsides and to cover rural areas, where fiber is even less practical.

As small cell architectures continue to evolve, it will be up to carriers and small cell providers to work together to perfect new design approaches that make engineering and economic sense. The early small cell installations have demonstrated positive price performance, but we have to perfect fronthaul design and closely manage cost of ownership to ensure that the promise of small cell density and the benefits of HetNet are fulfilled.

Mobile operators evaluating SDN and NFV for more flexible and cost-effective backhaul:

Infonetics Research released excerpts from its 2014 Macrocell Backhaul Strategies: Global Service Provider Survey, which provides insights into operator plans for macrocell backhaul.

“The mobile network is evolving to incorporate small cells, distributed antenna systems (DASs), remote radio heads (RRHs), and WiFi, and though the macrocell layer still does the heavy lifting when it comes to traffic handling, the backhaul network behind all this is becoming increasingly complex,” notes Richard Webb, directing analyst for mobile backhaul and small cells at Infonetics Research. “Our macrocell backhaul study reveals the extent to which operators are looking at software-defined networking (SDN) and network functions virtualization (NFV) solutions to provide greater backhaul flexibility and cost-savings.”

 

MACROCELL BACKHAUL SURVEY HIGHLIGHTS

  • Infonetics’ survey respondents have yet to scale their small cell deployments, but anticipate they will place over 20% of traffic from the macro network onto small cells by 2018
  • When asked if or when they will introduce software-defined networking (SDN) into the backhaul network, 29% of respondents say they are deploying or plan to deploy SDN at some point, while the majority (63%) are evaluating it as a possibility with no set timeframe
  • Among those surveyed, Ethernet on fiber will be the most-used technology for macrocell backhaul connections by 2016, followed by Ethernet-only microwave
  • Downstream bandwidth is the top-ranked service-level agreement (SLA) metric, rated very important by 92% of operators surveyed, followed by jitter, latency, and upstream bandwidth
  • Survey respondents not only seek vendors with strong macrocell backhaul product portfolios, but partners who can also support their strategies for holistic, flexible future-proofed networks

Huawei Displays SDN and NFV Technologies at SDN & OpenFlow World Congress in Germany

Huawei today showcased its software-defined networking (SDN) and network functions virtualization (NFV) technologies at the SDN & OpenFlow World Congress in Dusseldorf, Germany. At the event, Huawei discussed how industry partners can best utilize these technologies to further the development of the telecom industry, with specific focus on how its SoftCOM strategy will continue to help address this industry trend.

The SDN World Congress was advertised as an opportunity to examine developments, debate the issues and showcase the reality of SDN and NFV – and promises to be another milestone occasion for the whole market – carriers, data centres and enterprises.  There’s a NFV FORUM and Proof of Concept Zone – endorsed by ETSI as Forum Partner- at this conference as well.


“Huawei’s SoftCOM will unleash the full potential of SDN and NFV, building an open and flexible network infrastructure for the ICT industry. We hope to work with all industry participants to create a future-oriented open network ecosystem in the cloud ICT era,” said Ken Wang (Shengqing), President of Global Marketing and Solutions, Huawei.

As ICT technologies become increasingly cloud-based, telecom carriers are faced with the pressure of increased development costs and sluggish revenue growth. In this new era of ICT, carriers must now focus on evolving their businesses to address these challenges and regain competency. Based on the concepts of cloud computing, SDN, and NFV, Huawei developed the future-oriented telecom network architecture strategy, SoftCOM, which aims to help reconstruct the telecom industry from the perspectives of network architecture, network functions, as well as service and Observation and Measurements (O&M) models. The SoftCOM strategy enables telecom carriers to realize comprehensive network evolution and business transformation, thus creating and seizing new value opportunities through ICT integration. This approach will further help with establishing and advancing an open, interconnected, and innovative ecosystem, to increase and better leverage the aggraded industry value.

Focusing on technological development driven by business requirements, Huawei has experimented with numerous SDN and NFV innovations across all network fields and launched corresponding solutions to help carriers implement full-scale network and business transformation for the future. To date, Huawei has worked with more than 20 leading carriers around the world including Telefonica, China Mobile, China Unicom, and China Telecom, on over 60 joint SDN- and NFV-related innovation projects. In 2014, Huawei and global carriers executed several commercial SDN and NFV deployments, including the world’s first commercial SDN deployment in cooperation with China Telecom, the SDN-based Wo cloud project in cooperation with China Unicom, the SDN-based hybrid cloud project in cooperation with China Telecom, and an NFV-based vIMS joint project in Europe.

The SDN & OpenFlow World Congress saw Huawei reveal its new Flexible Ethernet solution and an innovative network architecture MobileFlow, as well as several prototype systems of its new technologies at the event. The Flexible Ethernet solution has the flexibility to support various dynamic software-configured combinations of different Ethernet sub-interfaces. It marks different data connections and services that require different data traffic, and match them to their correspondent sub-interfaces accordingly. The Flexible Ethernet is an Ethernet revolution that will change the industry dominated by the traditional fixed Ethernet forever, and would greatly impact the future IP network architecture. In addition, the MobileFlow structure has realized unified deployment of mobile network control functions through cloud, while the previous plane model is only capable of service forwarding and processing. Through the southbound interface, the mobile controller is now able to conduct fine-grained forwarding control of the distributed forwarding devices, and also open the control capability to their application layers.

Huawei will continue to focus on the development of its SDN and NFV-based cloud technology, with the aim of facilitating the industry’s network structural transformation for the future.

SIP trunking services market expected to grow 35% in 2014 & top $8 billion by 2018

Infonetics Research released excerpts from its new SIP Trunking Services market size and forecasts report, which tracks Session Initiation Protocol (SIP) trunking revenue, trunks, and average revenue per trunk.

SIP trunking is a means of synthesizing the Session Initiation Protocol and Voice over Internet Protocol (VoIP) to provide telephony services over data networks. The two leading SIP trunk providers are BroadVoice and 8×8, Inc.

SIP TRUNKING SERVICES MARKET HIGHLIGHTS:

 .    The global SIP trunking services market is on track to grow 35% in 2014, to $4.4 billion
.    The biggest market for SIP trunking services is North America, although new geographic markets continue to open up, helping fuel growth
.    More and more businesses are making the switch to SIP trunking, but they are not cutting 100% of connections to SIP on day one; rather, SIP is typically being deployed at one or two sites to start
.    Infonetics expects continued strong worldwide growth for SIP trunking over the next five years, forecasting the market to reach $8 billion in 2018
.    SIP trunking is being pitched alongside hosted PBX and unified communications (UC) services as more businesses seek hybrid solutions

Infonetics: 100G+ coherent network equipment moving to the metro

Infonetics Research released excerpts from its 2014 100G+ and ROADM Strategies: Global Service Provider Survey, which details the plans of operators transitioning optical transmission and switching equipment to higher-speed 100G+ wavelengths.

100G+ AND ROADM SURVEY HIGHLIGHTS:
.    Respondent operators have reasonable expectations for pricing for coherent metro-regional and access applications versus the core
.    When it comes to end-use applications for metro 100G, study participants view data center interconnect as the clear killer app for the next 12 months
.    Respondents also expect a greater uptake of 100GE transport when compared to previous years’ Infonetics surveys
.    Those surveyed expect 100G WDM to account for almost 40% of all metro wavelength deployments and 75% of the core network in 2017
.    Pluggable CFP and CFP2 technology is perceived by respondents as a more important technology for the metro this year than it was last year


“The big battleground for vendors of 100G-and-beyond coherent equipment and components has shifted to the metro as winners for long reach core applications have been decided,” says Andrew Schmitt, principal analyst for carrier transport networking at Infonetics Research.

“There are two very distinct markets for coherent technology. One market is deploying long haul coherent today and will transition to metro in the coming years. But there is another, separate (network provider) customer type that is already fully committed to deploying coherent technology in the metro today,” Schmitt adds. “These two markets have major implications for the supply chain regarding product specialization and the relative lack of interest in flex coherent technology by 
some customers.”


        

ABOUT INFONETICS’ 100G/ROADM SURVEY:

 For its 19-page 100G+ and ROADM (Reconfigurable Optical Add/Drop Mulltiiplexer) strategies survey, Infonetics interviewed 31 incumbent, competitive, mobile, and cable operators from EMEA, North America, and Asia that have an optical transport network using WDM. Together, the respondents represent a significant 33% of the world’s telecom revenue and 36% of global capex. The survey covers 100G WDM price points, metro coherent wavelength deployment trends, end-use applications for metro 100G, metro and core technology adoption rates, and key technologies for optical transport.

Infinera Targets Cloud for 100G Network Between Data Centers

https://www.sdncentral.com/news/infinera-gets-cloud-happy-100g-network-d…

Open Networking NOT truly OPEN without industry accepted Standards & APIs; Role of OpenStack Foundation?

There are so many flavors of “SDN” you can’t keep track of them.  The term “SDN” has come to ONLY mean “software control of a network.”   That could be anything and is a far cry from the original definition which included strict separation of the Control and Data planes, a “centralized controller” that computes paths for many packet forwarding engines (Data plane implementations) and a standardized API (Open Flow v1.3) as the “southbound API” between the Control and Data Planes.

What Guru Parulker of Stanford University called “SDN Washing” (non pure forms of SDN) have come to dominate the industry.  There are network overlay models with multiple instances of Control planes, network virtualization (overlay of a logical network over a physical network) using VMware technology or VxLAN tags, and extensions of proprietary, closed network equipment to accomodate some degree of user control over the network configuration and paths.

I don’t think AT&Ts SDN WAN uses Open Flow or even a centralized  SDN controller to compute paths/routes for multiple data forwarding “engines.”  Instead, they use a proprietary, dynamic routing protocol as described in this article: http://viodi.com/2014/09/18/atts-sdn-wan-as-the-network-to-access-deliver-cloud-services/

 
you will see end to end “orchestrated API control”  with no explanation of what that is.  But that’s presumably how network administrators “program” AT&Ts SDN WAN.  Of course, those and other APIs are proprietary to AT&T and their vendors/suppliers/cloud service provider partners, etc.

At the recent IT Roadmap-San Jose, CA conference, a speaker from Nuage Networks (owned by Alcatel-Lucent) referred to SDN as network virtualization using VxLAN tags.    That is not consistent with ONF definition of SDN https://www.opennetworking.org/sdn-resources/sdn-definition
VxLAN is a virtual networking solution to support a flexible, large-scale multi-tenant environment over a shared common infrastructure.  It is designed to provide the same Ethernet Layer 2 network services as VLAN does today, but with greater extensibility and flexibility. It’s supported by Cisco, VMWare, Arista Networks, Broadcom, Juniper, Citrix, Cumulus Networks, Red Hat, and others.  Here are a few references:
http://www.cisco.com/c/en/us/products/collateral/switches/nexus-7000-series-switches/vidoe_fundamentals_vxlan.html
http://www.vmware.com/files/pdf/techpaper/VMware-VXLAN-Deployment-Guide.pdf
http://www.broadcom.com/collateral/wp/VXLAN-WP101-R.pdf
http://en.wikipedia.org/wiki/Virtual_Extensible_LAN
VXLAN was officially documented by the IETF in RFC 7348. 
There will be several vendors which might interoperate using the VxLAN virtual network overlay model  But that networking gear won’t work on a pure SDN Open Flow network as defined by the ONF!

From this and many other examples, it seems SDN is “open” only to the extent of the SDN network provider (telco, DC operator, campus/ enterprise network) and its suppliers/vendors.  As such, I expect network equipment vendors to pick a few versions of SDN they’ll support.  

What Standards are Required for SDN:

IMHO, Open networking imples multi-vendor interoperability, which requires standards for functionality, protocols, APIs, and interfaces that are in the public domain.   I believe the following standards are needed for SDN:

1.  API/protocol between the Control Plane entity and the Data Plane entity (Open Flow v1.3????)

2.  API/protocol between the Control Plane entity and the Management/Orchestration/Automation entity.  It’s sometimes referred to as the “Northbound API”  or “Management plane API”

3.  Specification of exactly what functions the Management/Orchestration/Automation software entity performs, e.g. functional requirements.  See discussion below.
4.  API/protocol between the Control Plane entity and higher layer entities, e.g. Load Balancers, Application Delivery Controllers, Firewalls,  other virtual appliances. ONF calls that the “Northbound API”
5.  API/protocol between one “centralized” Control plane entity and another.  ONF refers to that as “East-West API,”  but no work has been done on it last time I checked.  When I asked Dan Pitt, what does one SDN controller use to communicate with another when the route/path is between two or more domains, he replied “use BGP for now.” 
6.  SDN specific OAM and network management.

Role of OpenStack:
An orchestration/management/automation software entity is required with an API to either the SDN Control Plane entity (“Northbound or Management API”) or to the NFV “virtual appliances.” 
At the 2014 SVIEF annual conference, Chris Kemp, founder of Nebula and the OpenStack Foundation told me that Open Stack http://www.openstack.org/  is the best solution for orchestration & management software with specific APIs.  But it’s years away (for being used in production networks) and not yet specified by any telecom standards body (e..g. ETSI, ITU, ANSI, ATIS, etc).  
OpenStack’s Neutron API can be used to integrate the provisioning and management of these network resources into the orchestration of the overall IT infrastructure.  Neutron’s open networking capabilities handle a wide range of tasks, including the management of both networks and IP addresses. Users can create their own networks, control traffic and connect servers using Neutron, while administrators can apply ONF’s OpenFlow and similar technologies to deliver software-defined networking, multi-tenancy and high levels of scalability.
Within the Open Stack Foundation, there’s a project called Open vSwitch  http://docs.openstack.org/havana/install-guide/install/apt/content/concepts-neutron.openvswitch.html     which is quite promising for open SDN designs.  
Open vSwitch includes OpenFlow (specified by the ONF), which enables one to define networking flow rules. Certain configurations use these rules to transfer packets between VLANs.  For example, Open vSwitch supports the VxLAN overlay model.

 

There’s also OpenStack Networking API v2.0 (neutron) Reference

which can be used for authentication, request/response, bulk create, etc.  These are described at:
The companies involved in SDN need to specify which Open Stack projects, specifications and APIs are needed for management and orchestration of networking functions.  But what SDO will do that?  ONF, ITU-T, ATIS?

Stay tuned for a follow up article on this topic, with the help of Mr. Kemp of Nebula!

Summary of Light Reading’s NFV and the Data Center Conference- 16 Sept 2014

Note:  This is a condensed summary of two previously published articles on this excellent conference.  

http://viodi.com/category/weissberger/

Introduction:

The telco data center [1] (DC) is likely to be the first place network operators deploy Network Virtualization/Network Functions Virtualization (NFV).  That was the opening statement at the Light Reading conference on NFV and the Data Center,  held Sept 16, 2014 in Santa Clara, CA.   A network virtualized data center was defined by the conference host as a “cloudified DC which integrates virtualized telecom network functions utilizing Virtual Network Functions (VNF) or Distributed VNFs.”

Note 1. Larger network operators (e.g. AT&T, Verizon) already operate “telco DCs” for web hosting, storage, cloud computing, managed services, and back end network management/OSS/BSS.  It will be easier for them (compared to those operators with no DC) to implement a NFV based telco DC.  See Heavy Reading Survey results below for more details on this topic.

Concepts and reference architectures from the  ETSI NFV specifications group were predicted to alter the data center from a siloed IT-centric model (separate compute /storage/ networking equipment)  to a harmonized network and IT domain model, in which virtualized telecom functions, e.g. policy control and application orchestration, are added to the growing list of computing demands on servers.  According to Light Reading, NFV will drive an entirely new set of storage, automation, management, and performance requirements, which are only now starting to be defined.

[One must assume that these VNF’s will be implemented as software in the DC compute servers, perhaps with some hardware assist functionality.   Realizing that vision will eliminate a lot of network equipment (hardware) in a telco’s DC and provide much more software control of network functions and services.]

Key industry trends discussed at this excellent 1 day conference included:

•The need for service providers to shorten their service delivery cycles and adopt agile approaches to delivering new services.

•The key role that automation of network processes will play in helping operators deliver more user control and network programmability.

•Taming network complexity remains a significant challenge.

•Services in the era of virtualization must still maintain security and reliability for which telecom has been known.

Key findings from Heavy Reading’s January 2014, multi-client study are presented.  Next, we summarize network operator keynotes from Century Link.  Part 2. will review the Orange, and NTT Communications keynotes as well as our summary and conclusions.

Panel Discussion:

NFV requires operators to find new ways of looking at basic network attributes like performance, reliability and security.  For example, performance metrics may change in migrating to NFV – from raw/aggregate performance to performance per cubic meter, or performance per watt.  Virtualization will transform many ways of configuring and managing network resources. 

However, a business case must be established for an operator to move towards network virtualization/NFV/NVFs.  The cost and ROI must be justified. Heavy Reading analyst Roz Roseboro opined that projects which get funded are those that will affect the top line, meaning increased revenues from new and existing services.  In that sense, NFV is more likely to get funding than SDN, because it will greatly help an operator increase service velocity/time to market and thereby realize more money.   SDN is more about OPEX reductions and efficiency she said.

Century Link Keynote: James Fege, VP of Network Strategy & Development

CenturyLink is counting on its Savvis acquisition to make them hugely successful in cloud computing and to build a “cloudified” telco DC for traditional network services.   Acquired in 2011, Savvis is a separate vertical entity within CenturyLink (which includes the former Embarq, U.S. West, Qwest and other companies. CenturyLink has successfully integrated the cloud orchestration and software development of Tier 3, and the platform-as-a-service capabilities of AppFog in their cloud computing capabilitites). 

According to Feger,  “Cloud is not ‘rust resistant.’  It must be: programable, self-service, and offer on-demand services.” 

The CenturyLink Cloud process and operations involve the following attributes:

  • Agile methodology
  • 21- to 30-day release cycles
  • DevOps team2
  • Minimum viable product (not explained)
  • Building block architecture which is API based
  • Constant feedback to improve operations and services

Note 2:    While network operations is traditionally a stand-alone function with dedicated staff, the DevOps model eliminates the hand-off from development to operations, keeps the developers in the feedback loop, and incentivizes developers to resolve problems or complications on their own instead of passing them to the Operations department. 

The realization of the above cloud attributes is via open applications programming interfaces to software that exists above the physical network.  Open source software will allow developers to offer their apps or services regardless of the underlying infrastructure, Feger said.  He was firm in his view that “agility combined with our network platform is CenturyLink’s differentiator.” 

Feger was quite honest during his talk.  He confessed that the service cycles on the network side are still measured in months, not weeks or days. By incorporating the agile technology approaches of the CenturyLink Cloud and the use of a DevOps model, CenturyLink hopes to improve on that.  But not this year or next.

“It will be a multi-year project to migrate our network to a cloud like set of capabilities, while minimizing (existing) customer disruptions.”

The take away here is that CenturyLink is attempting to leverage their highly regarded cloud capabilities to offer “cloud-like” L1 to L3 network services, e.g. IP MPLS VPN, Ethernet services, private line (e.g. T1/T3/OC3), broadband Internet access, video, and other wire-line services.   Service delivery times must become a lot shorter, while programmability, orchestration, and automation are necessary components to make this happen.  

Orange Keynote:  Christos Kolias, Sr. Research Scientist, Orange – Silicon Valley

Christos first described the the NFV Concept and Vision from his perspective as a founding member of the ETSI NFV specifications group.  It’s a quantum shift from dedicated network equipment to” virtual appliances.”

In the NFV model, various types of dedicated network appliance boxes  (e.g. message router, CDN equipment, Session Border Controller, WAN acceleration, Deep Packet Inspection (DPI), Firewall, Carrier grade IP Network Address Translation (NAT), Radio/Fixed Access Network Nodes,  QoS monitor/tester, etc.) become “virtual appliances,” which are software entities that run on a high performance compute server. 

In other words, higher layer network functions become software based virtual appliances, with multiple roles over the same commodity hardware and with remote operation possible.  “It’s a very dynamic environment, where (software based) network functions can move around a lot.  It’s extremely easy to scale,” according to Christos.

[One assumes that each such virtual appliance would have an open or proprietary API for orchestration, automation, and management of the particular function(s) performed.]

A few examples were cited for a network virtualized telco DC:

• Security functions: Firewalls, virus scanners, intrusion detection systems, spam protection

•Tunnelling gateway elements: IP-SEC/SSL VPN gateways

•Application-level optimization: Content Delivery Networks (CDNs), Cache Servers, Load Balancers, Application Accelerators, Application Delivery Controllers (ADCs)

•Traffic analysis/forensics: DPI, QoE measurement

•Traffic Monitoring: Service Assurance, SLA monitoring, Test and Diagnostics

Note:  This author DESPISES TLAs=three letter acronyms.  In many cases, the TLA used in a presentation/talk is much more recognizable in another industry, e.g. ADC =Analog to Digital Converter, rather than Application Delivery Controller.  Hence, I’ve tried to spell out most acronyms in this and the preceeding article on the NFV conference.  It takes a lot of effort as I’m not familiar with most of the TLAs used glibly by speakers.

Kolias said that the migration from network hardware to software based virtual appliances won’t be easy.  Decoupling NVFs from underlying hardware presents management challenges: services to NFV mapping, instantiating VNFs, allocating and scaling resources to VNFs, monitoring VNFs, support of physical/software resources.

NFV components in a virtualized telco DC might include:  server virtualization, management and orchestration of functions & services,  service composition, automation, and scaling (up and/or down according to network load).   There are lots of servers, storage elements, and L2/L3 switches in such a DC.  There’s also:  security hardware (firewalls, IDS/IPS), load balancers, IP NAT, ADC, monitoring, etc.

NFV in the Data Center will be more energy efficient, according to Kolias.  “It’s  the greenest choice for an operator,” Christos said.   With many fewer hardware boxes, NFV can bring the most energy efficiency to a data center (less energy consumed and lower cooling requirements).  That’s a top consideration for those massively power-hungry DC facilities. “You have to dispose of telecom hardware, but when we move things into software, it becomes more eco-friendly,” Kolias said.   “So yes, there is absolutely a fit for NFV in the Data Center,” he concluded.

Christos thinks it’s probably easier and faster to implement NFV in a telco DC, because there’s less compliance/ regulation and it’s a less complex environment – both technically and operationally.

Service chaining was referred to as “service composition and insertion,” with policies determining the chain order.  Customized service chains are possible with NFV, Kolias added. Ad-hoc, on-demand, secure virtual tenant networks are also possible.  For example, tunnels/overlays using the VxLAN protocol (spec from Arista, VMWare and Juniper).

Kolias also cited other benefits of “cloudification” — a term he admittedly hates. “For example, consolidating multiple physical network infrastructures in a cloud-based EPC (LTE Evolved Packet Core) can lead to less complexity in the network and produce better scalability and flexibility for service providers in support of new business models,” he noted.

Several other important points Christos made about NFV in the telco DC:

1. Virtual switches can be key functional blocks for management of multiple virtual switches and for programmable service chains.

2.  The Control plane could become part of management and orchestration in a unified, policy-based management platform, e.g. OpenStack. 

[That’s radically different than the pure SDN model (Open Network Foundation), where the Control plane resides in a separate enitity, which communicates  with the Management/ Orchestration platform (e.g. OpenStack) via a “Northbound” API.]

3.  Hardware acceleration can play a role in Network Interface Cards (NICs) and specialized servers.  However, they should be programmable.

4.  Challenges include:  Performance (e.g. increased VM-VM traffic requirements), Security Hybrid environment, and Scaling.

APIs will be important for plug-n-play, especially for open platforms like Google, Facebook, Microsoft, eg. WebRTC.  They can enable a plethora of innovative (e.g. ad-hoc/customized) services and lead to new business models for the telcos.  That would translate into monetization opportunities (e.g. for new residential and business/ enterprise customers, virtual network operators (VNOs), and others) for service providers.

Christos predicts that many service providers will move from function/service based networks to app-based models.  They will deploy resources, including Virtual Network Functions (VNFs) on-demand, as an application when the user needs them.   He predicted that smart mobile devices and the Internet of Things (IoT) will precipitate the adoption of APIs for telco apps.

Kolias summed up: “NFV can propel the move to the telco cloud. When this happens we will have succeeded as an NFV community!  NFV removes the boundaries and constraints in your infrastructure. It breaks the barriers and opens up unlimited opportunities.”

NTT Com Keynote:  Chris Eldredge, Executive VP of Data Center Services for NTT America (NA subsidiary of NTT Com)

Background: NTT Com is one of the largest global network providers in the world, in third place behind Verizon and AT&T. They provide global cloud services, managed services, and connectivity to the world’s biggest enterprises.  NTT Com has a physical presence in 79 countries, $112B in revenues, and 242K employees.  It’s network covers 196 countries and regions. The company spent $2.5B in R&D last year, with a North American R&D center in Palo Alto, CA.  Finally, they claim to be the #1 global data center and IP backbone network provider in the world.  [Chris said Equinix has more total square footage in their data centers than NTT, but they don’t have the IP backbone network.] 

NTT Com’s enterprise customers mostly use cloud for development and test applications. “It’s bursty in nature. They turn it up and turn it down,” Eldredge said.  It’s also used for OTT broadcasts of sporting events and concerts.   On January 1, 2014, NTT spun up 200,000 virtual machines (VMs) to meet demand for Europeans watching soccer matches on their mobile devices. After the soccer match was over, those VMs were de-activated.

With the Virtela acquisition, NTT Com has recently deployed their version of NFV capabilities in both their DCs and global network along with SDN based provisioning.

“SDN/NFV is a more scalable network technology that NTT Com is now using to provide cloud and managed services to a broad range of clients,” Eldredge said.  “It allows us to specialize and provide custom solutions for our customers,” he added.

The NFV (higher layer) services NTT Com is now offering include:  virtual firewall, network hosted applications accelerator, Secure Sockets Layer (SSL) VPN, IP-SEC gateway, automated customer portal (for full control of services, self deployment, self management, and full visibility), on premises harware based managed services which provide a fully integrated managed solution for NTT Com customers.

The above NFV enabled services can be easily applied, monitored and rapidly changed. NTT Com can customize applications performance and service levels for specific users and profiles.  In conclusion, Chris said that “NFV has become the next phase of the virtualized DC, extending the enterprise DC into the cloud.  [Such an extension, by definition, would be a hybrid cloud]

In answer to this author’s question on when and if NTT Com would use NFV to deliver pure (L1-L3) network connectivity services, Chris confessed that it wasn’t on their roadmap at this time.

Summary and Conclusions:

Operators are planning for NFV and some – like NTT Com – already have implemented several NFV enabled services.  Examples of NFV capabilities were clearly stated by Kolias of Orange Silicon Valley and Eldredge of NTT Com.  It starts with higher layer (L5-L7) network functions/capabilities, cloud and managed services.  However, it will take considerable time before the entire network is virtualized.  “NFV everywhere by 2020” is too aggressive, according to some.  And don’t expect mainstream connectivity functions (including Carrier Ethernet services, private lines, circuit switching, etc) to be virtualized anytime soon.

Early NFV adopters will  be challenged as they work through internal issues like breaking down their organizational silos and adapting their business models to a quicker, more agile manner of provisioning and controlling network resources and services. 

What happens to the network IT guy when the majority of network equipment disappears and is transformed into virtual appliances? Who maintains a compute server that’s also implementing many higher layer networking functions?  What trouble shooting tools will be available for NFV entities?

Automation and self service are crucial for the network operator to deploy services quicker and hence realize more revenues.   CenturyLink’s Feger said it best: “If you’re on a nine-month release strategy, your network isn’t really programmable.”

“Agility is an asset. You can only tame complexity,” noted Heavy Reading analyst and event host Jim Hodges, who quoted Brocade’s Kelly Herrell from an earlier presentation. “As an industry, we realize complexity is an inherent part of what we’re doing, but it’s something we have to address.”
