Gartner: Enterprise Data Network Services Market Moves to Transformational Technologies

Market Overview

Gartner forecasts that the market for enterprise data networking services in 2020 will be $157.5 billion, broadly unchanged from 2019 (see “Forecast: Enterprise Communications Services, Worldwide, 2017-2023, 4Q19 Update”).

 

The number of global NSPs included in this Gartner research has increased as more providers have met our revised inclusion criteria. In addition to large global providers, enterprises are increasingly willing to consider smaller providers, including managed service providers with little or no network infrastructure of their own (such as those featured in the “Market Guide for Managed SD-WAN Services”). Alternatively, enterprises may choose a combination of multiple regional providers.

Sourcing Trends

Providers are increasingly focused on providing the managed service platform (e.g., managed SD-WAN and NFV/vCPE); however, they are also more open to “bring your own access” and other flexible sourcing approaches for the network transport components.

The global network service market continues to move toward a more software-driven, as-a-service model, with increasing levels of visibility and self-service via portals and APIs available to enterprise customers.

However, this means providers are reluctant to allow deviations from their standard offerings, because that will require deployment of a custom solution at a higher cost that could rapidly become obsolete in this fast-moving market.

Operational Trends

The network buying discussion is gradually moving away from technologies toward outcomes and service levels. Providers continue to improve their SLAs with more-realistic objectives and more-meaningful penalties for failing to meet those objectives, increasingly including the right to cancel the service in the event of chronic breach. Installation lead times — a pain point for many enterprises with global networks — are starting to be covered by standard SLAs, and providers are striving to improve delivery times, although they remain frustrated by third-party/local access providers. The increasing speeds of cellular services are making this technology more useful as a rapid deployment (interim) solution. In addition, it provides a truly diverse backup option. However, the hype around 5G cellular replacing fixed connectivity should be treated with caution, due to maturity issues — especially coverage limitations.

Electronic quoting and ordering are increasingly widespread, with electronic bonding between the global providers and their local access providers. Self-service ordaining and/or provisioning, as well as the increased visibility of the service being delivered via portals continue to gain momentum. This is blurring the lines between managed services and self-management, to create a spectrum of co-management possibilities.

However, global networks are also becoming more complex, because transport becomes a hybrid of MPLS, internet and Ethernet; cloud endpoints are added; and SD-WAN and NFV technology are added. In addition, the internet, especially using broadband or cellular access, is an inherently less predictable service than MPLS. Visibility capabilities, sometimes referred to as performance analytics, can help by enabling enterprises see the actual performance of their applications.

Thanks to the continual investment in enhancing the customer experience, customer satisfaction with global NSPs is improving.

Network Architectures

New global network proposals are predominantly for managed SD-WAN services based on a hybrid mix of MPLS and internet transport, with different applications using the most appropriate link type. Most providers support a small portfolio of SD-WAN vendors, because the market is more fragmented and differentiated than the router market it is replacing. Some providers offer network-based SD-WAN gateways, allowing traffic to use the internet for access, but use the providers’ higher-quality, long-haul backbones.

Enterprises’ adoption of cloud IT service delivery remains key to transforming their WAN architectures. Fortunately for enterprises, global NSPs have deployed a range of capabilities to address enterprises’ cloud connectivity needs (see “Five Key Factors to Prepare Your WAN for Multicloud Connectivity”).

The providers in this research offer carrier-based cloud interconnect from their MPLS and Ethernet networks to leading CSPs, such as Amazon, Microsoft and Google. Most offer connection to additional cloud providers as well. The key differentiators are the specific cloud providers and the cities connected, and the ability to add virtualized services (e.g., security) into the cloud connection points.

Managed SD-WAN services typically offer the option of local internet access (split tunneling) from every site, which is especially useful for access to SaaS applications, such as Microsoft Office 365. Perimeter security can be provided on-site or as a cloud-based service. An option for managed SD-WAN services is for the provider to deploy network-based SD-WAN gateways to facilitate interconnection between SD-WAN and non-SD-WAN networks, improve scalability and avoid the need for traffic to traverse long distances over the internet. Alternatively enhanced internet backbone services may be available to improve the performance of cloud service access over the internet and to improve end-to-end performance, when using the internet as a transport link.

An increasing number of global WANs incorporate managed application visibility and/or WAN optimization, with some providers now offering application-level visibility by default. SD-WAN services, which operate based on application-level policies, also typically offer inherently higher levels of application visibility.

Network functions, such as edge routing, SD-WAN, security, WAN optimization and visibility, can be delivered as on-site appliances. However, many providers prefer to offer these as VNFs, running in NFV service nodes in their POPs or in uCPEs, which are essentially industry-standard servers, deployed at the customers locations, supporting one or more virtual functions. This makes it easy to rapidly change the functions deployed in the network and is also usually consumed on an “as a service” basis with a monthly subscription fee for each function.

Ethernet WAN services (virtual private line and virtual private LAN services) remain more niche. They are principally used for data center interconnection; high-performance connections, including extranets (such as trading networks); or for sites that are geographically close (i.e., Metro Ethernet). Different combinations of these services can be used to obtain different service levels appropriate to each enterprise location.

Providers are starting to offer NoD services, where bandwidth can be adjusted via a portal or APIs. Some of these services support multiple services (e.g., MPLS and internet) on a single access line, and also allow dynamic control of cloud connectivity.

Access Options

WAN access is evolving, with traditional leased-line access, such as T1 or E1 lines, no longer proposed in new deals, except when no other form of access is available, such as in rural locations or some emerging markets.

Pricing for these legacy service types is typically increasing, and, in some cases, the services are reaching the end of their life.

Traditional access lines have largely been replaced by optical Ethernet access at 10 Mbps, 100 Mbps, 1 Gbps or 10 Gbps. The scale economics of Ethernet access are very good, with each tenfold increase in speed, typically increasing cost by only two to three times. As a result, in developed markets, enterprises now tend to purchase access lines with much higher speeds than they initially require, with the port capacity limited to their current needs. This allows them to easily and quickly upgrade capacity in response to changing requirements.

For smaller, less critical or remote locations, broadband (increasingly, “superfast broadband,” such as very-high-speed DSL [VDSL], cable modem or passive optical network [PON]) is the access technology of choice, despite having no SLAs or poorer SLAs than Ethernet access. When enterprises require large numbers of broadband connections, they can sometimes find that they are able to get better pricing than that offered by global service providers by sourcing broadband access directly or from aggregators. Many providers now support “bring your own broadband.” This refers to the service provider delivering managed services over broadband sourced by the enterprise.

Finally, cellular connectivity (4G) and, in the future, 5G, is increasingly being used for backup, rapid deployment or temporary locations, although it does not offer SLAs. As with broadband, enterprises may be able to get attractive deals for data-only mobile services themselves, which will then be managed by their global provider.

Managed Services

Most global WANs are delivered on a managed service basis, with the on-site devices, such as routers, security appliances and WAN optimizers, provided and managed by the service provider. Transport links are usually sourced from the managed service provider, but might also be sourced by the enterprise, who would then give the managed service provider operational responsibility for them. Although more U.S.-headquartered multinationals are moving to managed network services, a significant number still manage their networks in-house and only source transport links from their global providers.

As more network functions, such as SD-WAN application policies or NoD bandwidth, are controllable via the providers’ portals and APIs, networks are moving more to a co-managed reality. In this case, responsibilities for various network management functions are divided between the provider and the enterprise.

Pricing Trends

Downward pressure on global network service prices is relentless (e.g., global MPLS services are undergoing unit price declines averaging 10% per year, although with strong regional variance). Gartner has produced research summarizing and predicting pricing trends for different services and geographies (see “Network Service Price Trends: What You Need to Know to Save Money on Your Next Contract Negotiation”). The response from providers varies, with some focusing on extending their own networks, while others are relying heavily on network-to-network interface (NNI) connections to partners to improve their regional coverage. Most providers are increasingly using carrier-neutral communications hubs, such as those operated by Equinix, to allow them to cost-effectively interconnect with multiple access, backbone and cloud providers.

These hubs, particularly when combined with NFV and/or SD-WAN, have dramatically reduced the level of investment required to be competitive in the global network service market. This has allowed smaller providers, including some of the more recent entrants to this Magic Quadrant, to offer solutions competitive with those of the largest providers. However, maintaining a consistent set of service features and user experiences across these different elements remains a challenge.

Change Underway:

The network service market is undergoing a major transformation, with new generations of software-based network technologies enabling new services and new business models that are less focused on large-scale infrastructure. To reflect these trends, this Magic Quadrant focuses on transformational technologies and/or approaches that address the future needs of end users, as well as today’s market.

Gartner defines the global network service market as the provision of fixed corporate networking services with worldwide coverage.

Current global network services evaluated in this Magic Quadrant include:

  • WAN Transport Services — These include Multiprotocol Label Switching (MPLS) service, Ethernet services and internet services, such as dedicated internet access (DIA), broadband and cellular.
  • Carrier-Based Cloud Interconnect (CBCI) — This is a direct connection between a service provider’s enterprise network services, such as MPLS and/or Ethernet services, and the private connection option of one or more cloud service providers (CSPs). CBCI can be established directly between the network service provider (NSP) and the cloud provider or via a cloud exchange, such as Equinix Cloud Exchange.
  • Managed WAN Services — These include managed software-defined WAN (SD-WAN). Although a minority of enterprises are renewing their managed router networks, most new managed global network deployments in 2019 were managed SD-WAN networks using a mix of MPLS and internet transport. This is a trend Gartner expects to continue. An option for managed SD-WAN services is for the provider to deploy network-based SD-WAN gateways to facilitate interconnection between SD-WAN and non-SD-WAN networks, improve scalability and avoid the need for traffic to traverse long distances over the internet.

Emerging global network services that will be evaluated include:

  • Network On Demand (NoD) — NoD services from NSPs enable enterprises to make real-time changes to access/port bandwidth, change the WAN service types delivered over a network port and, in some cases, add and remove endpoints (e.g., connections to cloud providers). This occurs under software control, via the provider’s web portal or APIs.
  • Network Function Virtualization (NFV) — NFV is an architecture to deliver multiple network functions, including routing, firewall, SD-WAN, WAN optimization, visibility and voice as software, termed virtual network functions (VNFs). NFV enables enterprises to rapidly (in minutes) deploy network functionality to locations where it is required. This functionality is the replacement for purpose-built hardware devices, such as routers, security devices or WAN optimizers. NFV can be implemented on universal customer premises equipment (uCPE; see below) or in NFV service nodes, located in the provider’s network, or in colocation facilities. NFV enables network functions to be activated on demand (and deactivated when no longer required) and consumed on an “as a service” basis. This can improve the agility and cost-effectiveness of the enterprise WAN.
  • Virtual Customer Premises Equipment (vCPE) — This is the use of industry-standard x86 devices (uCPE), rather than function-specific appliances, to deliver enterprise network edge functions, including WAN edge routing, SD-WAN, WAN optimization, visibility and security functions (e.g., firewalls).

In addition, it is highly desirable for providers to offer related network services, including managed WAN optimization, managed application visibility, and managed, network-related security services. Integrators, virtual operators and carriers may be included, but only if they will bid for stand-alone WAN deals and provide and manage offerings that include the WAN connectivity.

During the past 12 months, Gartner has seen continued changes in enterprise requirements and buying criteria for global networks. Enterprises are placing an ever-growing emphasis on their need for greater agility and especially enabling their organization’s adoption of cloud services and the Internet of Things (IoT). They are increasingly willing to consider smaller providers and innovative services, particularly those that can be consumed on an as-a-service basis. Therefore, they are placing less emphasis on supplier size, network scale and the availability of large numbers of provider staff to deliver customized capabilities.

NSPs are taking advantage of the marketplaces created by carrier hubs, such as those provided by Equinix and Digital Reality. This enables them to source access that’s distance-insensitive, at the national or even regional level, reducing the need to deploy large numbers of network points of presence (POPs). POPs are increasingly acting as gateways between access and backbone network services of various types, and cloud providers. In addition, they are serving as locations where virtualized network services, such as security, can be applied.

Internet services, including broadband, DIA and cellular, are growing in importance as transport options, alongside the continued use of MPLS and Ethernet services. New services such as managed SD-WAN, NoD services, NFV and vCPE, which transform the enterprise networking market, are being deployed to improve the agility of providers’ network solutions. Many of these services require a platform-based approach to delivering services, increasing the trend to move away from customized solutions, toward standard, off-the-shelf managed services, consumed on an as-a-service basis.

We are seeing a distinct split in providers’ attitudes toward NFV and vCPE. Some providers are “doubling down” on the technology, making it their default edge device offering. Others are still focusing on appliances at the network edge, frequently accompanied by network-based NFV, especially for services such as security.

 

Although delivering against a strong technological roadmap is important, it is equally important that services be delivered with good operational performance to implement and sustain them.

The inclusion and exclusion criteria for this year’s Magic Quadrant (see Figure 1), although similar to prior years, have been adjusted to reflect these trends.

Digital business initiatives are placing increasing demands on the enterprise network, increasing the needs for bandwidth (between 20% and 30% annually), reliability and performance. Video, live and stored, is driving significant increases in bandwidth, whereas IoT typically requires greater reliability.

 

A growing proportion of enterprise applications are being delivered as cloud services — infrastructure as a service (IaaS), platform as a service (PaaS) and SaaS. This requires incorporation of cloud endpoints into the network and a burgeoning need for data center-to-cloud and cloud-to-cloud connectivity.

Above all, digital business requires that enterprise networks become significantly more agile, to allow the rapid accommodation of new endpoints, new applications and new network capabilities. However, enterprises continually need to do all of this, while optimizing their WAN expenditure.

To address these requirements service providers are deploying a range of new networking technologies. SD-WAN is now the default offering for new network deployments and major refreshes, while the virtualization of network edge functions, using NFV and vCPE, is gradually becoming more common. CBCI is also mainstream, complemented by emerging NoD services.

Growing use of the internet as a network transport option, together with cloud endpoints, is resulting in performance uncertainty, and is driving significant demand for application visibility services.

Fortunately, enterprises can choose from a wide selection of solution providers, most operating across multiple geographies. This breadth is allowing enterprises to choose between one, two or many providers to find the best solution for their specific needs. These decisions will be based on geographic requirements, the specific service required and the preferred sourcing approach (i.e., the enterprise’s desire to manage multiple networks from multiple providers). Competition continues to drive down unit prices for global networking services. However, in a market in which there are no meaningful price lists, enterprises still need to use competitive procurement practices and strong negotiations to obtain the best prices.

 

AT&T FlexWare and Cybersecurity power Exide’s Digital Transformation

AT&T is powering Exide’s digital transformation with its FlexWare network virtualization solution.  AT&T FlexWare is one of AT&T’s core software-centric services from the company’s “edge solutions portfolio.” AT&T says its near real-time service cuts long set up times and complex processes.

FlexWare enables businesses to launch virtual network functions (VNFs) to improve productivity and communication across its geographically dispersed physical sites. With FlexWare, AT&T can move the VNFs, such as firewall or security VNFs, to devices on a company’s network.

“Our technology will give Exide the support it needs to continue operating at high standards and to prepare for new opportunities in a 5G world,” said John Vladimir Slamecka, AT&T Region President for Europe, the Middle East and Africa. “We’re building a platform that is ready for new data hungry apps made possible with the arrival of 5G; such as AR and VR. That’s why we are moving compute resources closer to the network edge, opening the door to new experiences and opportunities.”

AT&T’s FlexWare, for virtualized network edge services, is now in place across Exide’s global locations, including throughout Europe, North America and Asia Pacific.  FlexWare at the edge allows Exide to use both highly secure MPLS and internet access services for its network needs. Starting with network routing, Exide is able to access all wide area network components utilizing high bandwidth capabilities to help provide greater flexibility as the needs of each change over time. AT&T FlexWare also allows Exide to fulfill its centralized IT requests without needing local site support.

……………………………………………………………………………………………………….

Exide is a battery and energy storage company which was founded 130 years ago.  It manufactures and recycles batteries for a broad range of industrial and transportation applications including cars, boats, forklifts and uninterrupted power units.  The company has more than 10,000 employees located across 80 countries.

“Our global presence in today’s fast paced technology environment presents the unique challenge of blending reliable legacy platforms with emerging digital solutions.  This requires a data transport infrastructure that supports a broad number of traditional and disruptive applications,” said Brian Woodworth, Exide Chief Information Officer. “AT&T is leading the way as a trusted and visionary provider of network edge solutions, so naturally we turned to AT&T to collaborate with us on our digital journey to become the preferred supplier to our customers across the globe,” he added.

Exide is also using managed network security services from AT&T Cybersecurity.   From an AT&T report on this vital topic:

The security landscape is growing increasingly treacherous as hackers of every type continue to evolve their attack strategies to evade detection while maximizing profit from their time and effort. It doesn’t matter if it’s an organized criminal gang looking to make money from ransomware schemes, covert state-sponsored groups attempting to steal data and disrupt operations, or just malevolent individuals trying to impress others in the hacker community—every bad actor is smarter than they were last year, and better equipped to wreak havoc.

However, we wonder if AT&T takes cybersecurity seriously for its own customers, like this author who has experienced two AT&T account unexplained security breaches in the last few months?

…………………………………………………………………………………………………………………..

AT&T says it is “offering customers like Exide unrivaled visibility and security through people, process and technology allowing them to better protect their global business.”  This author certainly hopes that happens!

Cisco announces AI/ML and Security Software to transform networks

The Network Gets Smarter, Simpler and More Secure with Artificial Intelligence and Machine Learning:

Cisco today announced software innovations designed to make managing and securing networks easier. As today’s businesses increasingly invest in digital technologies, IT teams are struggling under the amplified workload. To alleviate this burden and allow IT to focus on delivering innovation, Cisco is introducing new artificial intelligence and machine learning capabilities to allow IT teams to function at machine speed and scale through personalized network insights. As part of its broadened capabilities offering, Cisco is also unveiling innovations to more effectively manage users and applications across the entire enterprise network – from campus networks and wide-area networks, to data centers and the IoT edge.

IT teams currently face a daunting challenge. According to 451 Research, nearly two-thirds of organizations report that their IT teams are facing increased workloads; but increased IT headcount is in the cards for only about one-third of companies in the coming year. At the same time, it has never been more imperative for IT to deliver great digital experiences in this hyper-competitive landscape. Bridging the gap between the needs of a business and the resources available requires innovative network automation and analytics tools, powered by data and underpinned by artificial intelligence and machine learning.

Cisco’s new capabilities will grant IT teams:

  • More Visibility: No two networks are the same. Environments are always changing. Cisco continuously collects relevant data from local networks and correlates it against the aggregate deidentified data set to create highly individualized network baselines. These baselines constantly learn and adapt as the number of devices, users and applications evolves, and as environments change.
  • Greater Insights: Network complexity has grown beyond the human scale of processing. Cisco uses machine learning to correlate the immense amount of data coming from the network against the individualized network baselines to uncover the issues that will have the greatest impact on the network. This improves issue relevancy, alerting IT of the issues that matter most. It also discovers trends and patterns, so IT can pre-emptively identify issues before they become a problem.
  • Guided Actions: Cisco uses machine reasoning algorithms and automated workflows to perform the logical troubleshooting steps that an engineer would execute to resolve a problem. This helps IT detect issues and vulnerabilities, analyze the root cause and execute corrective actions faster than ever.

“As the pace of change and diversity of the environment continues to rapidly evolve, Cisco is committed to continually simplifying our solutions,” said Scott Harrell, Senior Vice President and General Manager of Cisco’s Enterprise Networking Business. “Artificial intelligence and machine learning can enable businesses to efficiently discern which issues to prioritize, becoming more nimble and proactive. This will have a profound effect on network operations and the IT teams that run them. At Cisco, we’re future proofing our networks and the workforce through automation and intelligence.”

Reducing Complexity with the Multidomain Network
To help customers simplify the unprecedented complexity of modern IT, Cisco is building an architecture that spans every domain of the intent-based network — campus, branch, WAN, IoT, data center and cloud.  Cisco has created solutions optimized to meet the unique needs of each of these networking domains. Today, Cisco is introducing new integrations, so users have a secure, consistent experience no matter where, when or how they connect. The new integrations allow for end-to-end:

  • Network segmentation: The integration of Cisco SD-Access with Cisco SD-WAN and Cisco Application Centric Infrastructure (ACI) makes it easier for IT teams to consistently authorize, onboard and segment users and devices across campus, branch, data center and cloud networks, even when users and applications change. Because of this segmentation, IT is able to safeguard against unauthorized access to sensitive data and critical applications.
  • Application experience: Cisco now automatically conveys application requirements between the data center and the WAN, allowing the network to select the best path and prioritize traffic even if applications move or change. This allows IT teams to dynamically elevate application performance across the enterprise and branch.
  • Pervasive security: As an industry leader in cybersecurity, Cisco is leveraging its security innovations across all domains. By extending the ability to detect threats in encrypted traffic across public clouds, and by protecting the campus, branch and WAN against threats, Cisco says it’s providing the end-to-end security customers need.

Cisco’s Ecosystem Drives Innovation
As the network becomes increasingly programmable, Cisco’s ecosystem of partners and developers has been crucial to drive innovation. To help organizations keep up with the relentless pace of change, Cisco DevNet, the company’s developer program, has introduced community-backed efforts to make adopting networking technology easy and accessible. This includes machine learning and artificial intelligence developer resources, which include use cases and resources to get started with new applications; the Cisco DevNet Automation Exchange, which contains a curated repository of code for all levels of network automation use cases; and the Cisco DNA Center Platform, which helps networking professionals and software developers alike to build new applications and integrations.

Layer 123 Network Transformation Congress: Status of Network Automation, Orchestration, Zero (or Low) Touch Provisioning, SDN & NFV

The REALITY:

Disappointingly small number of deployments, many open source software and open API organizations (ONF, Linux Foundation, MEF, TM Forum, OCP, etc), pop-up consortiums (Cloud RAN, Open RAN, other disaggregated hardware), defunct standards organizations (e.g. ETSI, ITU-T, IEEE) that only produce functional requirements, reference architectures, and white papers or none of the above.  Nothing that can be actually implemented via standardized exposed interfaces or APIs.

Discussion:

Tuesday April 30th and Wednesday May 1st I spent the entire day and early evening at the Layer 1,2,3 Network Transformation Congress which assessed the state of SDN, NFV, Open Source MANO (OSM), Open APIs (TM Forum and MEF), other Open Source management software, and topics related to what network operators have been talking about for at least eight years- computer controlled network automation and orchestration of services (sometimes referred to as service chaining).  Contrary to the rah, rah cheerleader talk from a few network operators (especially AT&T), telco deployment of this new age open source software for automation and control of networks has been very slow.  NFV actual deployments are minimal (if not zero) and SDN has become a marketing term that can mean any software control of network functions.  Every network operator and cloud service provider uses different protocols, many of which they invented (e.g. Google’s routing protocol for DCI) along with  a sprinkling of open source code (such as a SDN Controller).

Decades of man years has been invested in network operator proprietary network management software, which is used to provision new services, keep track and maintain existing services, facilitate moves and changes.  One speaker said that he’d like to see light touch provisioning rather than zero touch.  Another said that they stack the new automation, provisioning and orchestration software on top of their legacy software

For the cloud giants (e.g. Amazon, Google, Tencent, etc), it has been done, but in almost a totally proprietary fashion with almost all the network automation, control and management done using in house generated code.  Amazon spoke at the conference and, in response to this author’s question, suggested the different types of network access for AWS.  Microsoft spoke, not about Azure but their private enterprise network which doesn’t use any open source code.  Moreover, it took two years to get 22 new sites connected via direct internet connections (<600M bit/sec) that would normally be served by copper lines (bonded DSL or short reach fiber).

Selected Quotes from Conference Participants:

Long time colleague Craig Matsumoto (whom I met when he was EE Times, but now at 451 Research) coined a new term during his presentation –  “software programmable interconnection” (SPI) for data centers.  Craig said: “We talk a lot about telcos. The question is what does network transformation mean for the data center world? What are they doing about it?  We came up with this new term, software programmable interconnection (SPI) . It’s basically about the idea that data centers connect with one another with a fabric.”  In this author’s opinion the SPI term captures the wide variety of software being used within and between data centers!

“For me covering data centers after covering telcos for so long, they’ve (data center operators) talked to me about using the SDN for pretty much anything that involved automation and the network. Anything that has software is SDN to them. We came up with a different term as a good way to encapsulate that some kind of software is being used that might or might not be SDN,”  Matsumoto added.

Tuesday’s keynote speaker and Wednesday moderator Roy Chua, Founder and Principal of AvidThink – a boutique market research firm:

“With regard to the key takeaways, I think you’ve captured them. I was very impressed at the level of candor in the discussions and presentations. I liked the concrete examples and quantification of NFV uptake challenges and the recognition that we need to solve constrained problems than try to boil the ocean. There was definitely good content…..Appreciate all the excellent questions and enjoyed the discussion at lunch. And I am most grateful for your endorsement of the analysis that I do.”

This author recommends only a select few (<5) networking market analysts that do primary market research.  Roy is one of those select few!

From Kaustubha Parkhi, Principal Analyst at Insight Research (a well respected Indian market research firm):

“There is no doubt that LSO [2] is essential. Equally essential is the pruning of its objectives and scope, which becomes a bit overwhelming at times. The objectives, in the present form are so broad-based that they cover everything from billing functions to network equipment deployment.”   –>More on LSO in a forthcoming IEEE Techblog article.

Note 2. LSO (Lifecycle Service Orchestration) is the set of MEF-defined specifications enabling standardized service orchestration based on standardized lifecycles of end-to-end connectivity services across one or more network service domains.  A key contribution is open APIs – to automate the entire lifecycle for services orchestrated across multiple provider networks and multiple technology domains within a provider network.  LSO enables service providers to transition from a silo-structured BSS/OSS approach towards flexible end-to-end orchestration that unleashes the value of SDN and NFV.  Standardized LSO APIs are critical for enabling agile, assured, and orchestrated services over automated, virtualized, and interconnected networks worldwide.

Conclusions:

I was pleasantly surprised by the honesty (if not brutal frankness) of the speakers.  What a refreshing change from the never ending hype, exaggeration and lies one hears at most networking conferences – including the IEEE 5G Summits :-((.

With over 20 pages of handwritten notes and so many important things revealed, I am not able to write a detailed conference summary report on this free website.  Hence, I solicit readers to email me what they’d like me to cover in future posts, after reading the conference agenda for Tuesday- Day 1 and Wednesday -Day 2.

Please remember that the IEEE Techblog does not accept advertisements so we can tell the real truth.  Also we don’t charge for viewing posts or comments (no pay wall).  Finally, this author has managed and contributed to this and predecessor website (community.comsoc.org) for over 10 years without any pay.
