Standardization work on software-defined networking (SDN), a key priority for ITU-T in 2013, is progressing well in ITU-Ts Study Group 11 (SG11) with a number of important specifications nearing maturity following a meeting of two specialized groups in June.

SG11 is tasked with developing the signalling requirements and protocols on SDN. The work will align with the functional requirements and architectures developed by ITU-Ts Study Group 13. In addition a Joint Coordination Activity on SDN was recently established to coordinate the work.

Matt Lopez, NEC Corporation and Rapporteur on Question 4/11 Signalling requirements and protocols for Bearer and Resource control in emerging telecommunication environments: ITU-Ts consensus-based standards process provides an opportunity for the industry to agree common objectives for the emerging SDN environment, and resulting standards will do much to unify industry players in their work to introduce SDN on a large scale. 

Draft Recommendations in progress include a document specifying the scenarios and signalling requirements using SDN technologies in Broadband Access Network (BAN). A software-defined BAN (SBAN) simplifies network configuration, making deployment of new services easier and improving broadband service provision. Working document is available here (members only).

Another document provides a gap analysis of SDN work going on across ITU and other standardization bodies as well as a framework, requirements and architecture for signalling in SDN. Working document is available here (members only).

In addition SG 11 experts are working on a Recommendation that describes the scenarios and signalling requirements for a unified intelligent programmable interface for IPv6 service deployment. This working document is available here.

The next physical meetings of the groups focusing on SDN will take place November 2013 in Uganda. For updated information see ITU-T Study Group 11 homepage.
