Dell CTO: Enterprise use cases will dominate 5G public and private deployment models
The 5G telecom ecosystem will shift to become more enterprise driven from consumer-focused in 2021 and the fundamental architecture become software-defined, said John Roese, global chief technology officer, Dell Technologies.
“In 2021, we will have true standalone 5G materialize and it will include advanced features. (This author strongly disagrees as there are no standards for 5G SA and there will be no roaming or portability as a result.).
Enterprise use cases will dominate the technical landscape of 5G for both public and private deployment models. (We agree on that point). The fundamental architecture of 5G (core network) will move away from the telco and shift to a cloud (native) and IT architecture, which will be open and software-defined for the first time,” said Roese recently while briefing the journalists on the technology trends this year. The Dell senior executive said 5G infrastructure ‘needs to be developed in a very different way with software defined architecture.’
5G SA and Non Stand Alone Core Network
Roese said in 2021 and 2022 the industry would see the shift to building edge computing platforms that can run multiple edge experiences and software-defined services on them to solve the edge proliferation problem. “Edge platforms will become major new areas of on-premise IT capacity delivered as both product and as-a-service,” he added.
Dell said 2021 will also be a prominent year for the quantum computing and semiconductor ecosystem. “This is the year that will enable broader software development ecosystems to experiment with quantum computing. This is the first year that a computer scientist with no prior access to quantum computing can go into a simulator and start to learn the language of quantum,” said Roese.
According to the company, the industry will move from the era of homogeneous compute to an era of heterogeneous compute. This means that homogenous compute like x86 will be highly augmented with domain specific architectures (Accelerators), and semiconductor ecosystems are being reorganized for this domain.
Big Names Clash over 12 GHz for 5G despite it NOT being included in ITU M.1036 – Frequency Arrangements for IMT
Light Reading’s Mike Dano, says there is a contentious issue of whether 5G networks should be permitted to use the 12 GHz band. Apparently, the clash is between Charlie Ergan’s Dish Network and Dell (YES) vs AT&T and Elon Musk’s SpaceX (NO).
Interestingly, 12 GHz (more precisely 12.2-12.7 GHz Band ) is NOT one of the frequency bands in the revision to ITU Recommendation M.1036-6, which specifies ALL frequency bands for the TERRESTRIAL component of IMT (including IMT 2020).
–>Please refer to Editor’s Note below for more on the M.1036 revision which may contain a cop-out clause to permit use of any frequency for IMT 2020.SPECS. Mike Dano wrote:
According to at least one high-level source involved in the debates, the FCC might make some kind of ruling on the topic as soon as December. A senior FCC official confirmed that the agency is considering allowing 5G in 12GHz, but declined to comment on whether the item would be addressed during the FCC’s December meeting. Based on the increasingly contentious filings on the topic, it certainly appears that the fight over 12GHz is escalating.
In the U.S., the FCC exhaustively licensed the 12.2-12.7 GHz band in 2004-2005 timeframe through competitive bidding. The US terrestrial fixed licenses are co-primary with Direct Broadcast Satellite (DBS) and Non-Geostationary Orbit Fixed Satellite Service (NGSO FSS). In April 2016, a petition was filed seeking license modifications under section 316 to permit terrestrial mobile use in the band. Although the petition went through public notice/comment phases, no decisive action has been taken yet. Meanwhile, in August, 2017, FCC issued an inquiry into new opportunities in the mid-band spectrum between 3.7 GHz and 24 GHz. The combination of favorable propagation characteristics (as compared to bands above 24 GHz) and the opportunity for additional channel bandwidth (as compared to bands below 3.7 GHz), raises the potential of these bands to be used for next generation wireless services.
“The time has finally come for the commission to issue a Notice of Proposed Rulemaking (NPRM),” wrote RS Access this week in a filing to the FCC. Dell’s private money management firm backs RS Access, which owns 12GHz licenses and has been pushing for rules allowing 5G operations in the band. An NPRM by the FCC would signal a formal effort to decide on the matter, potentially sometime next year.
“Given the twin national imperatives of bringing spectrum to its highest and best use while unleashing spectrum for broadband connectivity, issuing a Notice of Proposed Rulemaking will allow debate to move from hollow rhetoric to the types of pragmatic solutions the country needs to accelerate 5G investment and innovation,” echoed Dish Network in its FCC filing.
AT&T and SpaceX are firmly against the idea of the FCC taking action. Instead, they argue that 5G operations in the 12 GHz band would affect their existing activities in 12GHz (AT&T’s DirecTV satellite TV service uses a portion of the band, as does SpaceX’s Starlink satellite Internet service).
“The parties urged the commission to deny the MVDDS Petition [a coalition including Dish and RS Access] for rulemaking outright or, at most, to issue a notice of inquiry rather than a Notice of Proposed Rulemaking given the current state of the record in this proceeding,” wrote AT&T and SpaceX – along with Amazon’s Kepler Communications, satellite companies Intelsat and SES, and bankrupt OneWeb – in their joint FCC filing. A note at the end stated: “See MVDDS 5G Coalition Petition for Rulemaking to Permit MVDDS Use of the 12.2-12.7 GHz Band for Two-Way Mobile Broadband Service, RM-11768 (filed Apr. 26, 2016) (“MVDDS Petition”).”
12 GHz proponents were hoping the FCC would discuss that issue at its November meeting. That’s unlikely as the main agenda item for that meeting will be to free up the 5.9GHz band for unlicensed operations as well as vehicle-to-vehicle communications using the C-V2X standard.
Dano concludes as follows:
The heavyweights involved in the 12 GHz proceeding are pulling out all the stops in the hopes they can get the FCC to act on one last contentious piece of spectrum policy before Biden begins his first term or President Trump begins his second. After all, Trump’s current FCC chairman, Pai, has not said whether he will stay on at the agency for Trump’s second term.
Editor’s Note: IMT 2020 Frequency Free for All?
At the conclusion of its Oct 2020 meeting, ITU-R WP5D could NOT agree on revision of draft recommendation M.1036-6 which specifies frequency arrangements to be used with the terrestrial component of IMT, including IMT 2020.SPECS. So that document has yet to be sent to ITU-R SG5 for approval.
The 5D Frequency Aspects WG Oct 2020 report stated:
“The current version of the draft revision with these further proposed edits is contained in document 5D/TEMP/243(Rev.1) and Editor’s Notes have been included in the document to clarify the current situation.”
“Looking at the current situation with some of the critical and urgent deliverables of WG Spectrum Aspects & WRC-23 Preparations, it is clear that whilst progress has been made in some less controversial areas, there are a significant number of areas where very diverging and sometimes polarized views remain. It is the view of the WG Chair that the current situation with such polarized views and no room for compromise solutions is disappointing and that we cannot continue with this approach at the next meeting if we want to be successful in completing these critical outputs by the required deadlines. We must all put more efforts into finding efficient ways to advance the discussions and in particular to focus on middle ground and compromise solutions rather than repeating initial positions.”
Furthermore, the UNAPPROVED draft revision to M.1036-6 has several cop-outs. For example:
“That Recommendations ITU‑R M.1457, ITU‑R M.2012 and ITU‑R M.[IMT-2020.SPECS] contain external references to information on operating bands for IMT technologies which may go beyond the information in Recommendation ITU-R М.1036 and may cover broader frequency ranges as well as further uplink/downlink combinations” OR for ONLY IMT 2020.SPECS:
“That Recommendations ITU‑R M.[IMT-2020.SPECS] contains external references to information on operating bands for IMT technologies which may go beyond the information in Recommendation М.1036 and may cover broader frequency ranges as well as further uplink/downlink combinations.”
Note also, that the hotly debated 12 GHz frequency band the Dish and Dell are proposing for 5G is NOT contained in the draft revision to ITU-R M.1036-6. But the cop-out disclaimer above, would permit 12 GHz and any other frequency to be used for IMT 2020, which would obviously negate the purpose and intent of that ITU recommendation.
Dell to offer SD-WAN service based on VMware Velocloud platform
Dell Technologies announced it has started offering a co-branded SD-WAN service with its affiliate VMware, based on the latter’s VeloCloud platform. Previewed at Dell Technologies World in May, the new service is now globally available and supported.
This Dell EMC SD-WAN Solution combines VMware SD-WAN by VeloCloud with modern appliances in multiple configuration options. The service is backed by Dell EMC support, supply chains, and services.
“Dell EMC and VMware are rebuilding the network for the cloud era – with everything open, automated and software-defined,” said Tom Burns, senior vice president & general manager, Dell EMC Networking & Solutions. “New SD-WAN solutions powered by VMware and network fabric management delivered by SmartFabric Director raise the stakes when it comes to network virtualization and security in today’s highly-distributed software-defined enterprise. We’re just getting started on our combined innovation.”
Collaboration between Dell EMC and VMware to:
- Re-define the network for the cloud era with tighter integration and combined development efforts
- Modernize network operations and reduce WAN costs with new Dell EMC SD-WAN Solution – one-stop solution combining VMware SD-WAN by VeloCloud, Dell EMC managed infrastructure
- Simplify data center fabric deployment, operations through enhanced visibility across virtual and physical networks with new Dell EMC SmartFabric Director
Customers have a choice of public, private or hybrid cloud network for enterprise-grade connection to cloud and enterprise applications; branch office enterprise appliances and optional data center appliances; software-defined control and automation; and virtual services delivery. Software subscription options can be upgraded to accommodate changing business requirements for features, duration and bandwidth.
The Dell EMC SD-WAN Solution has three key components:
- SD-WAN Edge powered by VMware – networking specific, purpose-built appliances designed for high efficiency and reliability
- SD-WAN Orchestrator – cloud-based management and orchestration software services from VMware, managed by Dell EMC
- SD-WAN Gateways – a global network of more secure, application-focused access gateways from VMware to handle WAN traffic
At VMworld, Dell EMC and VMware also announced SmartFabric Director, for software-defined networking that enables the physical switch underlay infrastructure to keep pace with the changing demands of virtualized and software-defined networks. Dell EMC SmartFabric Director enables data center operators to build, operate and monitor an open network underlay fabric based on Dell EMC PowerSwitch Series switches.
The Dell EMC SmartFabric Director is a network orchestration solution jointly developed with VMware that enables organizations to synchronize the deployment of a physical switch fabric with the virtual network and gain comprehensive visibility at both the physical and virtual network layers. Organizations can then potentially configure the network fabric in significantly less time than traditional methods. When integrating the SmartFabric Director with VMware vCenter or NSX/NSX-T, organizations can achieve end-to-end visibility of the physical network and all supported virtual overlays. To help organizations continuously monitor fabric health, SmartFabric employs telemetry to collect switch operational data and display metrics graphically at both the network fabric and switch levels. SmartFabric Director extends the two related companies’ shared vision of a software-defined data center by simplifying the definition, creation and deployment of data center fabrics with intent-based auto-provisioning and enhanced visibility and management between virtual and physical network environments.
Key features include:
- VMware vSphere and VMware NSX-T Data Center Integration – Tight integration with VMware vCenter and NSX-T enables the physical underlay/fabric to be correctly provisioned for the smooth functioning of application workloads in a VMware software-defined data center
- Leaf/Spine Fabric Automation – SmartFabric Director uses a declarative model that allows the user to express intent with a set of three well-defined fabric types. Fabric discovery is an ongoing process and ensures that the wiring is consistent with the user-defined intent and removes guesswork for rapid auto-provisioning
- Fabric Visibility – SmartFabric Director supports highly scalable and flexible streaming telemetry to gather key operational data and statistics from the fabric switches. Comprehensive, highly-intuitive visualization of the time-series data and other information greatly simplifies day-to-day fabric operations
- Fabric Lifecycle Management – Upgrading switch images is a critical operation in a data center. SmartFabric Director automates the download, install and verification process and ensures that switches are upgraded with the correct images
Dell said that this new service is important for organizations that are using the network virtualization version of SDN [1.] and need to help make sure their physical underlay networks are finely tuned for their overlay network environment. A lack of visibility between the two layers can lead to provisioning and configuration errors, hampering network performance. The new product will be available worldwide in September.
Note 1. The classical version of SDN, with a centralized controller and packet forwarding engines replacing hop by hop IP routers never really gained critical market mass, despite claims by Guru Parulkar, PhD, that everything else was “SDN WASHING.”
“Our customers today expect us to deliver the best and most advanced network solutions to solve their business needs,” said QOS Networks CEO, Frank Cittadino. “As a trusted partner to Dell EMC, we’re excited to do that with an SD-WAN solution that marries cost effective hardware with a dedicated orchestrator and VMware gateway. We combine that with our 5-Tool monitoring and management platform.”
“ESG was impressed with how the Dell EMC SmartFabric Director can help organizations to gain comprehensive visibility into the physical and virtual layers of their core networks and ensure that they are synchronized,” said Bob Laliberte, senior analyst, ESG Research. “We see how the SmartFabric Director can significantly ease the time-consuming process of creating and deploying a network fabric, while simultaneously verifying it will operate as intended.”
“VMware and Dell EMC are driving public cloud simplicity and utility across the entire network,” said Tom Gillis, senior vice president and general manager, networking and security business unit, VMware. “With this new SD-WAN solution, Dell EMC customers will be able to leverage the industry’s only hyperscale architecture for SD-WAN deployed at thousands of customers and more than 150,000 locations globally. Our joint engineering on SmartFabric Director will offer customers a tightly-integrated solution for physical to virtual networking visibility, further simplifying network operations and troubleshooting.”
