AT&T outlines plans for Software-Defined Network in 2018 and beyond

AT&T, which has previously stated plans to virtualize and software-control 75% of its core network functions by 2020, said that it is on target to reach the 65% virtualization milestone this ahead, coinciding with the rollout of mobile 5G service.

In a blog post, Chris Rice, Senior Vice President – AT&T Labs, Domain 2.0 Architecture and Design, outlines several major open source initiatives that the company has been spearheading to drive network transformation.

  • ONAP – The operating system for Network Clouds. Since formation a year ago, the project now brings together over 50 of the largest network and cloud operators and technology providers from around the globe, representing more than 60% of the world’s mobile subscribers. AT&T is leading the software contribution and together with project members plans to deliver the second ONAP release, Beijing, in the second quarter of this year.
  • DANOS – The operating system for individual white box servers that power a virtualized network. And we recently announced we are taking white boxes, running on DANOS, to scale in our network and will plan to install as many of 60,000 of these white box routers to support our 5G build out over the next few years.
  • Acumos – An industry-first AI platform and marketplace, co-created with Tech Mahindra, that makes it easy to chain multiple microservices together in a simple drag-and-drop interface. And The Linux Foundation recently announced the public availability of Acumos, meaning anyone can now access the platform and begin building AI applications. We’re also releasing our Acumos whitepaper, where we highlight our direction and efforts in this area.
  • Akraino Edge Stack – A complete software platform for edge computing systems and applications. The Linux Foundation also recently announced that Intel among others have signed on as members of the community. We’re seeing early indicators of progress that are encouraging, and this growing collaboration will help to expedite the maturity and adoption of edge cloud.


AT&T also plans to roll out over 60,000 white box routers over the next several years across the U.S. to enable advanced services on its mobile 5G infrastructure. These white box routers run the “Disaggregated Network Operating System,” or dNOS, which uses technology from its acquisition of Vyatta.

"White box represents a radical realignment of the traditional service provider model,” said Andre Fuetsch, chief technology officer and president, AT&T Labs. “We’re no longer constrained by the capabilities of proprietary silicon and feature roadmaps of traditional vendors. We’re writing open hardware specifications for these machines, and developing the open source software that powers these boxes. This means faster hardware upgrades, since anyone can build to these specs. And software upgrades that move at internet speed. We’re doing this all while keeping costs low so we can focus on expanding our nationwide mobile 5G footprint for our customers as quickly as possible."

OpenContrail is rebranded as "Tungsten Fabric"

OpenContrail, which is the SDN framework originally created by Juniper Networks and open sourced in 2013 and which is now hosted by The Linux Foundation as an open-source network virtualization platform for the cloud, has changed its name to Tungsten Fabric.

Tungsten Fabric provides a single point of control, observability and analytics for networking and security. It is integrated with many cloud technology stacks, including Kubernetes, Mesos, VMware and OpenStack. It supports private cloud, hybrid cloud and public cloud deployments such as AWS and GCE. Tungsten Fabric includes a high-performance vRouter that connects container, VM and bare-metal applications, and a controller which orchestrates network overlays, switch fabrics and router gateways.

The Linux Foundation said Tungsten Fabric is now deployed at massive global scale, across public and private IaaS, CaaS and PaaS environments ranging from hyperscale cloud providers and telecom operators to enterprises.

Tungsten Fabric’s mission is "to build a ubiquitous, easy-to-use, scalable, secure and cloud-grade SDN stack that provides a network fabric capable of connecting diverse environments."

Contributors and community members include Aricent, AT&T, Bell, Cavium, CertusNet, CloudOps, CodiLime, Intel, Juniper Networks, Lenovo, Mellanox, Mirantis, Netronome, Orange, SDN Essentials, TechTrueUp, and Yandex.

“We are pleased to create Tungsten Fabric with a neutral governance under The Linux Foundation,” said Arpit Joshipura, general manager, networking, The Linux Foundation. “The set up allows Tungsten Fabric to collaborate with other Linux Foundation and Networking projects. We’re looking forward to expanded collaboration across a growing software-defined ecosystem.”

The DANOS Project promises a Unified Network Operating System

The Linux Foundation will host a new Disaggregated Network Operating System (DANOS) project to enable community collaboration across network hardware, forwarding and operating system layers.

DANOS is initially based on AT&T’s “dNOS” software framework of an open, cost-effective and flexible alternative to traditional networking operating systems.

A first code release is expected the second half of 2018.

“We are pleased to welcome DANOS to The Linux Foundation community of open, collaborative innovation,” said Arpit Joshipura, General Manager of Networking, The Linux Foundation. “DANOS will provide an open NOS framework that leverages existing open source resources and complementary platforms such as switches and white box routers. We invite others in the broader ecosystem to join the effort to accelerate innovation and creation of an industry-standard disaggregated NOS.”

“As far as we know, DANOS is an industry first: an open-source, carrier-grade operating system for wide area networks,” said John Medamana, Vice President, Packet Optical Network, AT&T. “DANOS is a milestone for us and the industry, and we’re excited to see how developers and other users implement and build upon it.”

“ONF has been a champion of disaggregation, white boxes and open source and in this regard, we are happy to see DANOS launched as a carrier-grade, open source network OS for white boxes,” said Guru Parulkar, Executive Director, ONF. “We are looking forward to DANOS and ONF’s recent open source platform Stratum, thin switch OS, working together.”

Ciena adds ONAP elements to its Blue Planet Platform

Ciena announced enhanced policy capabilities into its Blue Planet intelligent automation platform that incorporates the architectural framework from the Linux Foundation’s open-source Open Networking Automation Platform (ONAP) to aid network providers’ evolution to more adaptive, software-centric networks. Specifically, Ciena Blue Planet is adding support for ONAP virtual network function (VNF) descriptors and packaging specifications to the already supported ETSI ISG NFV Release 2 specification.

Ciena said its new Blue Planet policy subsystem will support advanced closed-loop automation use cases, such as preventing a potential failure or dynamically scaling capacity to support growing bandwidth demands.

“The future of networking lies with openness and the concept of ‘choice’, allowing network operators to select best-of-breed technologies and solutions. These Blue Planet enhancements bring us closer towards the common goal of software-led, policy defined, network transformation. They also help forge a path for more adaptive networks that can self-learn, self-configure, self-heal, and self-optimize by constantly assessing network status,” stated Steve Alexander, Chief Technology Officer, Ciena.

Leading operators expand ONF mission to create Reference Designs as Gold Standards

AT&T, China Unicom, Comcast, Google, Deutsche Telekom, NTT Group, Telefonica, and Turk Telekom have agreed to back a new strategic plan for the Open Networking Foundation (ONF) focused on developing reference designs for open source, next-generation SDN solutions.

The operators will work together inside the ONF to create Reference Designs (RDs) to serve as “gold standards” for combining component projects into common platforms upon which operators will build solutions.  Each RD will be championed by a select group of operators, and will be designed with participation by invited supply chain partners sharing the vision and demonstrating active investment in building open source solutions.

The work activity will span all network layers, including mobile infrastructure, the edge cloud, multiaccess edge, and optical transport. The ONF has assembled partnerships with OEMs, systems integrators, VNF vendors, platform software developers, next-gen ODMs and chip companies.

The ONF, which was founded in 2011 and is based in Menlo Park, California, has been behind leading open source projects such as ONOS, Trellis and CORD. These projects have gained significant traction with operators as eighteen tier-1 operators are actively testing and trialling these solution. At least two tier-1 operators are moving into production with projects in 2018.

“The ONF is pleased to share our new 2018 strategic plan for market transformation,” said Andre Fuetsch, President and Chair of the ONF Board, and Chief Technology Officer and President, AT&T Labs. “This plan will position ONF as a premier, operator-driven community and will better align and accelerate open systems solutions to the marketplace. The plan is highlighted by two major components: 1) operators and ONF will work together to create common modular reference designs using components such as white boxes and open source platforms, and 2) operators and ONF will work on driving the components of the reference designs to be production-ready, and in selected areas will create integrated implementations of the designs.”

“Operators’ commitment to take open source solutions into production represents the next big step in realizing the full potential of software-defined, disaggregation and open source. It is also heartening to see operators’ determination to enable a new supply-chain that is well aligned with their goals. Clearly this is a landmark moment and it will set our industry on a new course for years to come. I am delighted that operators consider the ONF their partner in pursuit of this important agenda,” said Guru Parulkar, Executive Director for the ONF.
