AT&T Recalibrates Supplier Domain Program for SDN and NFV

AT&T launched the next generation of its Supplier Domain Program with the aim of selecting vendors to support its rapid evolution to cloud-based infrastructure leveraging Network Function Virtualization (NFV), Software Defined Networks (SDN) and modern operational approaches.

The Domain 2.0 initiative is expected to significantly reduce the time required to pivot to this target architecture while accelerating time-to-market with technologically advanced products and services.  Specifically, AT&T plans to simplify and scale its network by:

  • Separating hardware and software functionality;
  • Separating network control plane and forwarding planes; and
  • Improving management of functionality in the software layer.   

Under the Supplier Domain 2.0 Program, AT&T plans to begin selecting vendors and awarding business beginning in late 2013 and through 2014.  The company said it expects some of these capabilities will come from its current providers, while others will require some new providers with different skills and capabilities.

AT&T also noted that it is not revising its previously announced capital expenditure guidance for 2014-15 as a result of this announcement.  However, in the next five years, AT&T expects this program to reflect a downward bias toward capital spending.

"Our goal is to ensure that each investment accelerates our move towards an advanced all-IP broadband, all-wireless, and all-cloud infrastructure, delivers on the full promise of game-changing technologies, provides an industry leading customer experience, and maintains focus on a capital-efficient network," said Tim Harden, President, AT&T Supply Chain.

In September 2009, AT&T outlined a new "Domain Supplier 1.0" program aimed at transforming the way it purchases network equipment. As a key part of the program, the company has established a number of "domains" -- areas of the future network bounded by a particular technology set, such as wireline access. Within each of these domains are target technologies. For example, the wireline access domain includes technologies such as IP/DSLAM and FTTx.  Each domain will have two suppliers selected and pre-qualified by AT&T. 

AT&T said it will work closely with selected suppliers over a multi-year period in order to define solutions that meet current and future needs. This includes sharing timelines, project roadmaps and other information, enabling suppliers to more quickly realize revenue due to expedited deployment of their hardware or software. In addition, regardless of the size of the initial business award from AT&T, each supplier within a domain will have an opportunity to expand the award beyond its initial scope. 

OIF Outines Carrier Requirements for Transport SDN

The Optical Internetworking Forum (OIF) Carrier Working Group has completed a carrier requirements document addressing the transport network relevant part of a Software Defined Networking (SDN) architecture.

The document, "OIF Carrier Working Group Requirements on Transport Networks (TN) in SDN Architectures", works to identify the following:

  • Functions that need to be provided by a Control Plane enabled TN to an SDN controller or Orchestrator for realizing SDN use cases, applications and services
  • Orchestrator functional requirements to ensure the desired coordination between functions and services spanning across multiple layers in a TN and crossing multiple SDN domains to achieve end-to-end service orchestration
  • The combination of TN-relevant SDN architecture components – Data Plane, Control and Management Plane, and Orchestrator – and the relationship among them are referred to as “Transport SDN”.

The document supports the evolution of transport networks towards SDN architectures, summarizing what is already available and highlighting new features and functionalities to support the deployment of SDN applications,services and technologies.

The OIF said the next step will be to develop an SDN framework document that will provide future SDN related specifications and Implementation Agreements and also give structure to future OIF interoperability demonstrations. The OIF's focus on Transport SDN involves the management, control and data plane layers of the network, as well as the new Orchestrator – coordinating actions among data centers and transport networks.  Among carriers, there is a strong desire for a consistent set of SDN related standards and specifications to enable a seamless migration to SDN architectures.  With a carrier requirements document in hand, equipment vendors can work to specify interfaces among SDN components such as network elements, different types of controllers and orchestration instances.

"I am more than happy that we have achieved our first milestone in defining carrier requirements on Transport SDN,” said Hans-Martin Foisel of Deutsche Telekom and the OIF Carrier Working Group chair and OIF board member.  "This will not only guide our next steps inthe creation and implementation of technology to support Transport SDN but also will focus our communications with other SDOs and forums so that we can work together to streamline the different aspects of Transport SDN."

The OIF has planned a public workshop on “Transport SDN: Cutting Through the Hype - Enabling Technologies, Practical Use Cases, and Apps” for Monday, February 10, 2014 in San Jose, CA.  In addition, the OIF is in the planning stages for a 2014 interoperability demonstration that would address Transport SDN.
