AT&T deploys dis-aggregated IP edge routing platform

AT&T deployed a next-gen open disaggregated IP edge routing platform into its production environment with support from Broadcom, Cisco, and UfiSpace. 

The hardware platform being used for this edge application is identical to that previously announced for AT&T’s IP/MPLS core, demonstrating the true openness of the hardware. AT&T said common hardware enables consistent maintenance processes and sparing. The Broadcom Jericho2-based hardware designs have been accepted by OCP, and compatible products are available from other ODMs. The UfiSpace portfolio consists of three components: a 40x100G line card system, 10x400G line card system, and a 48x400G fabric system. These building blocks are deployed using the highly flexible Distributed Dis-Aggregated Chassis (DDC) design in various configurations to build routers with capacity anywhere between 4 Tbps to 192 Tbps. 

Cisco’s IOS-XR Network Operating System provides the management and control functions for the solution. Some of the key features for the peering use case are BGP Flowspec, unicast Reverse Path Forwarding (uRPF), and port mirroring which collectively will allow AT&T fine granular monitoring and mitigation actions for security threats such as Directed Denial of Service (DDoS) attacks. 

“The first IP edge use case is peering – the system that connects AT&T’s IP network with that of other Internet Service Providers (ISPs)”, said Andre Fuetsch, AT&T’s CTO for Network Services. “But this is just the tip of the iceberg; we are working with Cisco on developing additional edge use cases that will include broadband, IP content, Ethernet, mobility, and VPN services. We have started the journey to converge the disparate edge implementations we have today onto common software and hardware driving uniformity, simplification, and agility.” 

“Jericho2's scalability allows the hardware platform to be used from the core to the edge of the AT&T network, while enabling a thriving ecosystem that supports their vision of a disaggregated, flexible, and simplified network infrastructure, said Ram Velaga, senior vice president and general manager, Core Switching Group, Broadcom. “Broadcom is pleased to work with AT&T to enable merchant silicon solutions for end-to-end deployments,”   

“The internet of the future is supported by an automated, software-defined network that can easily support the cloud-and-app-powered world we live in,” said Jonathan Davidson, SVP and GM , Mass Scale Infrastructure Group, Cisco. “Cisco’s broad portfolio of industry -leading silicon, systems and software disaggregation is making the internet better and stronger. Together with AT&T we are marking a milestone in the industry with the convergence of the IP edge using open, dis-aggregated hardware and software-only models designed to fit a broad spectrum of commercial arrangements.” 

“This is a really big development in the networking eco-system,” Fuetsch said. “This model gives us options and flexibility in our supply chain and enables us to use best-in-breed products whether they come from established or disruptive suppliers. And this is well past lab experiments; the technologies and eco-system have matured, and we are now into the production deployment phase.”

AT&T deploys open disaggregated core router

AT&T has deployed its open disaggregated core routing platform on its 400G transport network. The router leverages technology from Broadcom, DriveNets, and UfiSpace. 

The white box hardware, which was designed and manufactured by UfiSpace, is based on Broadcom’s Jericho2 switching silicon and Distributed, Dis-aggregated Chassis (DDC) design. It consists of three components: a 40x100G line card system, 10x400G line card system, and a 48x400G fabric system. These building blocks can be deployed in various configurations to build routers with capacity anywhere between 4 Tbps to 192 Tbps.

DriveNets Network Cloud solution and its  Network Operating System (NOS) software provides the management and control of the white box hardware. This enables MPLS transport across AT&T's global, multi-service core backbone. The software then connects into AT&T’s centralized SDN controller that optimizes the routing of traffic across the core.

AT&T notes that the deployment of this dis-aggregated core routing platform is coupled with the deployment of the company’s next gen long haul 400G optical transport platform.

“I’m proud to announce today that we have now deployed a next gen IP/MPLS core routing platform into our production network based on the open hardware designs we submitted to OCP last fall,” said Andre Fuetsch, AT&T’s CTO of Network Services, in his keynote speech at the Open Networking and Edge Summit (ONES). “We chose DriveNets, a disruptive supplier, to provide the Network Operating System (NOS) software for this core use case.”

“We are thrilled about this opportunity to work with AT&T on the development of their next gen, software-based core network,” said Ido Susan, CEO of DriveNets. “AT&T has a rigorous certification process that challenged my engineers to their limits, and we are delighted to take the project to the next level with deployment into the production network.”

AT&T contributes Distributed Disaggregated Chassis white box to OCP

AT&T has contributed its specifications for a Distributed Disaggregated Chassis (DDC) white box architecture to the Open Compute Project (OCP). The contributed design aims to define a standard set of configurable building blocks to construct service provider-class routers, ranging from single line card systems, a.k.a. “pizza boxes,” to large, disaggregated chassis clusters.  AT&T said it plans to apply the design to the provider edge (PE) and core routers that comprise its global IP Common Backbone (CBB).

“The release of our DDC specifications to the OCP takes our white box strategy to the next level,” said Chris Rice, SVP of Network Infrastructure and Cloud at AT&T. “We’re entering an era where 100G simply can’t handle all of the new demands on our network. Designing a class of routers that can operate at 400G is critical to supporting the massive bandwidth demands that will come with 5G and fiber-based broadband services. We’re confident these specifications will set an industry standard for DDC white box architecture that other service providers will adopt and embrace.”

AT&T’s DDC white box design, which is based on Broadcom’s Jericho2 chipset, calls for three key building blocks:

  • A line card system that supports 40 x 100G client ports, plus 13 400G fabric-facing ports.
  • A line card system that support 10 x 400G client ports, plus 13 400G fabric-facing ports.
  • A fabric system that supports 48 x 400G ports. A smaller, 24 x 400G fabric systems is also included.

AT&T deploys open disaggregated core router

AT&T has deployed its open disaggregated core routing platform on its 400G transport network. The router leverages technology from Broadcom, DriveNets, and UfiSpace. 

The white box hardware, which was designed and manufactured by UfiSpace, is based on Broadcom’s Jericho2 switching silicon and Distributed, Dis-aggregated Chassis (DDC) design. It consists of three components: a 40x100G line card system, 10x400G line card system, and a 48x400G fabric system. These building blocks can be deployed in various configurations to build routers with capacity anywhere between 4 Tbps to 192 Tbps.

DriveNets Network Cloud solution and its  Network Operating System (NOS) software provides the management and control of the white box hardware. This enables MPLS transport across AT&T's global, multi-service core backbone. The software then connects into AT&T’s centralized SDN controller that optimizes the routing of traffic across the core.

AT&T notes that the deployment of this dis-aggregated core routing platform is coupled with the deployment of the company’s next gen long haul 400G optical transport platform.

“I’m proud to announce today that we have now deployed a next gen IP/MPLS core routing platform into our production network based on the open hardware designs we submitted to OCP last fall,” said Andre Fuetsch, AT&T’s CTO of Network Services, in his keynote speech at the Open Networking and Edge Summit (ONES). “We chose DriveNets, a disruptive supplier, to provide the Network Operating System (NOS) software for this core use case.”

“We are thrilled about this opportunity to work with AT&T on the development of their next gen, software-based core network,” said Ido Susan, CEO of DriveNets. “AT&T has a rigorous certification process that challenged my engineers to their limits, and we are delighted to take the project to the next level with deployment into the production network.”

AT&T contributes Distributed Disaggregated Chassis white box to OCP

AT&T has contributed its specifications for a Distributed Disaggregated Chassis (DDC) white box architecture to the Open Compute Project (OCP). The contributed design aims to define a standard set of configurable building blocks to construct service provider-class routers, ranging from single line card systems, a.k.a. “pizza boxes,” to large, disaggregated chassis clusters.  AT&T said it plans to apply the design to the provider edge (PE) and core routers that comprise its global IP Common Backbone (CBB).

“The release of our DDC specifications to the OCP takes our white box strategy to the next level,” said Chris Rice, SVP of Network Infrastructure and Cloud at AT&T. “We’re entering an era where 100G simply can’t handle all of the new demands on our network.

We’re confident these specifications will set an industry standard for DDC white box architecture that other service providers will adopt and embrace.”

AT&T’s DDC white box design, which is based on Broadcom’s Jericho2 chipset, calls for three key building blocks:

  • A line card system that supports 40 x 100G client ports, plus 13 400G fabric-facing ports.
  • A line card system that support 10 x 400G client ports, plus 13 400G fabric-facing ports.
  • A fabric system that supports 48 x 400G ports. A smaller, 24 x 400G fabric systems is also included.

AT&T points out that the line cards and fabric cards are implemented as stand-alone white boxes, each with their own power supplies, fans and controllers, and the backplane connectivity is replaced with external cabling. This approach enables massive horizontal scale-out as the system capacity is no longer limited by the physical dimensions of the chassis or the electrical conductance of the backplane. Cooling is significantly simplified as the components can be physically distributed if required. The strict manufacturing tolerances needed to build the modular chassis and the possibility of bent pins on the backplane are completely avoided.

Four typical DDC configurations include:

  • A single line card system that supports 4 terabytes per second (Tbps) of capacity.
  • A small cluster that consists of 1 plus 1 (added reliability) fabric systems and up to 4 line card systems. This configuration would support 16 Tbps of capacity.
  • A medium cluster that consists of 7 fabric systems and up to 24 line card systems. This configuration supports 96 Tbps of capacity.
  • A large cluster that consists of 13 fabric systems and up to 48 line card systems. This configuration supports 192 Tbps of capacity.
  • The links between the line card systems and the fabric systems operate at 400G and use a cell-based protocol that distributes packets across many links. The design inherently supports redundancy in the event fabric links fail.

DriveNet scales its disaggregated router to 400G

DriveNets, a start-up based in Israel, announced 400G-port routing support to its Network Cloud software-based disaggregated router.

The company says its Network Cloud is the only router on the market designed to scale 100/400G ports up to performance of 768 Tbps. Inspired by the hyperscalers, Network Cloud runs the routing data plane on cost-efficient white-boxes and the control plane on standard servers, disconnecting network cost from capacity growth.


DriveNets’ latest routing software release supports a packet-forwarding white-box based on Broadcom’s Jericho2 chipset which has high-speed, high-density port interfaces of 100G and 400G.

The platform is now being tested and certified by a tier-1 Telco customer.

DriveNets was founded in 2015 by Ido Susan and Hillel Kobrinsky. Susan previously co-founded Intucell, which was acquired by Cisco for $475 million. Kobrinsky founded the web conferencing specialist, Interwise, which was acquired by AT&T for $121 million.

In February, the company emerged from stealth with $110 Million in Series A funding.

AT&T announces nationwide coverage for 5G

AT&T announced nationwide coverage status for its 5G network, which now covers a population footprint of 179 million people.

AT&T has enabled dynamic spectrum sharing (DSS) technology in numerous markets.  DSS allows carriers to share the same channel between both 4G and 5G users simultaneously, based on demand.

"Our strategy of deploying 5G in both sub-6  (5G) and mmWave (5G+) spectrum bands will provide the best mix of speeds, latency and coverage that are needed to enable revolutionary new capabilities to fuel 5G experiences for consumers and businesses,” said Chris Sambar, EVP of Technology Operations. “Our competitors are still working to provide that same mix, which for them could take months or even years. What we offer is available to consumers and businesses today, and we’re not slowing down. As we have throughout our 144-year history, we’ll continue to innovate and invest in our network to expand our 5G coverage to more consumers and businesses across the country.”

AT&T: COVID-19 impacted revenues

Citing the impact of COVID-19 across all its business segments, AT&T reported Q2 revenues of $41.0 billion versus $45.0 billion in the year-ago quarter.

The COVID-19 impact included 338,000 mobile accounts which ceased paying their monthly bill and for which the company continues to provide service under the Keep America Connected programs but which are now considered "disconnects" for accounting. AT&T also saw lower content and advertising revenues at WarnerMedia, drops in domestic video and legacy wireline services, and currency exchange pressure in Latin America.

“Our solid execution and focus in a challenging environment delivered significant progress in the quarter, most notably the successful launch of HBO Max, resilient free cash flow and a strengthened balance sheet,” said John Stankey, AT&T chief executive officer. “Our resilient cash from operations continues to support investments in growth areas, dividend payments and debt retirement. We are aggressively working opportunities to sharpen our focus, transform our operations and continue investing in growth areas, with the customer at the center of everything we do.”

Highlights:

  • Mobile service revenues were down 1.1% due to decline in international roaming; equipment revenues up year over year.
  • 17.7 million premium TV subscribers – 886,000 net loss; 91,000 attributed to Keep America Connected programs.

AT&T pays down $5.3 billion in debt ahead of schedule

AT&T announced early repayment of six series of bonds totaling approximately $4.3 billion and prepayment of term loans totaling $1.0 billion. The total principal of these prepayments is approximately $5.3 billion.

AT&T said its goal is to continue improving its credit quality even as it remains committed to paying a dividend to its shareholders and investing in its growth areas — fiber, 5G and HBO Max. For full-year 2020, AT&T expects its dividend payout of free cash flow ratio will be in the 60% range. This gives the company the flexibility to continue to reduce its debt levels during 2020.

AT&T tests Nokia's RAN Intelligent Controller over commercial 5G

Nokia and AT&T conducted a limited live trial of RAN Intelligent Controller (RIC) over the AT&T commercial 5G mmWave network in New York City.

Last year, AT&T and Nokia announced their collaboration to co-develop the RIC software platform, in alignment with the O-RAN Alliance target architecture. The RIC software is available at the O-RAN Software Community.

For the recent trial, AT&T and Nokia ran a series of external applications, called “xApps,” at the edge of AT&T’s live 5G mmWave network on an Akraino-based Open Cloud Platform. The xApps used in the trial were designed to improve spectrum efficiency, as well as offer geographical and use case-based customization and rapid feature onboarding.

Ultimately, the trial achieved its test goals. Both companies tested the RAN E2 interface and xApp management and control, collected live network data using the Measurement Campaign xApp, the neighbor relation management using Automated Neighbor Relation (ANR) xApp, and tested RAN control via the Admission Control xApp – all with zero interruption to the live commercial network.

Mazin Gilbert, VP of Technology and Innovation at AT&T, said: “This successful trial is a testament to what we can achieve through openness and collaboration. Together with the O-RAN Alliance, AT&T and Nokia will continue to develop and contribute to the E2 interface and the RIC platform to help enable an intelligent and flexible 5G network.”

Michael Clever, Head of Edge Cloud Platforms at Nokia, said: “We are excited about the success achieved by the joint AT&T and Nokia team in proving out the RIC over AT&T's 5G network in such a great city. This represents a major milestone toward the advancement of RAN network intelligence, openness and programmability, with the ultimate goal of improving wireless networks efficiency and end user experience.”

AT&T and Nokia collaborate on open RAN platform

AT&T and Nokia are collaborating on an open software platform under the ORAN Alliance to open up access to 5G radio access networks (RANs). The goal is faster, more flexible service deployments and programmability within a rapidly-evolvable RAN.  The ORAN Alliance aims to enable a multi-vendor open ecosystem of interoperable components for the disaggregated RAN.

AT&T said it is commencing development of a software platform for the RAN Intelligent Controller (RIC), to enable the creation of open source software that is aligned with the O-RAN target architecture. AT&T and Nokia are co-creating the platform code to accelerate the deployment of open source software for the 5G RAN.



Some highlights:

  • The RIC platform will provide a set of functions and interfaces that allow for increased optimizations through policy-driven closed loop automation 
  • The platform will be architected in the form of an extensible real-time microservices framework coupled with a radio information database and key open control plane interfaces for mobility management, spectrum management, load balancing, radio resource control and RAN slicing to name a few.  
  • Implementations of these functions, sourced from multiple vendors, could be mixed and matched on a single network infrastructure. 
The platform will also enable interfaces to third-party applications for enhanced mobility functions such as cross layer optimization and machine learning inferences.

AT&T also plans to increase its engagement in Akraino Edge Stack, a Linux Foundation project focused on building production ready cloud infrastructure for edge deployment in open source. In particular, AT&T has also signed a multiyear co- development agreement with Nokia to further expand Akraino Edge Stack capabilities supporting the needs of the RIC and other edge cloud platform deployments.

Open RAN Policy Coalition seeks to diversify supply chain

A new Open RAN Policy Coalition has been formed to promote policies that will advance the adoption of open and interoperable solutions in the Radio Access Network (RAN) as a means to create innovation, spur competition and expand the supply chain for advanced wireless technologies including 5G.

The coalition believes that the U.S. Federal Government has an important role to play in facilitating and fostering an open, diverse and secure supply chain for advanced wireless technologies, including 5G, such as by funding research and development, and testing open and interoperable networks and solutions, and incentivizing supply chain diversity.

As evidenced by the current global pandemic, vendor choice and flexibility in next-generation network deployments are necessary from a security and performance standpoint,” said Diane Rinaldo, Executive Director, Open RAN Policy Coalition.  “By promoting policies that standardize and develop open interfaces, we can ensure interoperability and security across different players and potentially lower the barrier to entry for new innovators.”

Open RAN Policy Coalition founding members include Airspan, Altiostar, AT&T, AWS, Cisco, CommScope, Dell, DISH Network, Facebook, Fujitsu, Google, IBM, Intel, Juniper Networks, Mavenir, Microsoft, NEC Corporation, NewEdge Signal Solutions, NTT, Oracle, Parallel Wireless, Qualcomm, Rakuten Mobile, Samsung Electronics America, Telefónica, US Ignite, Verizon, VMWare, Vodafone, World Wide Technology, and XCOM-Labs.
