An ITU workshop on software-defined networking (SDN) will gather a global selection of standardization experts to progress SDN standards-development with one aim to establish efficient coordination  of future work.

SDN is a promising route towards the introduction and realization of network virtualization, a major shift in networking technology which will give network operators the ability to establish and manage new virtualized resources and networks without deploying new hardware technologies. ICT market players see SDN and network virtualization as critical to countering the increases in network complexity, management and operational costs traditionally associated with the introduction of new services or technologies.

SDN proposes to decouple the control and data planes by way of a centralized, programmable control-plane and data-plane abstraction. This abstraction will usher in greater speed and flexibility in routing instructions and the security and energy management of network equipment such as routers and switches.

The upcoming workshop responds to Resolution 77 - Standardization work in ITU-T for software defined networking agreed by the World Telecommunication Standardization Assembly (WTSA-12) in Dubai, UAE, 20-29 November 2012. SDN was emphasized as a strategic priority for ITU-T by the meeting of the Chief Technology Officer (CTO) Group, 18 November 2012 (The 2012 CTO Meeting Communiqué can be found here). The Global Standards Symposium (GSS-12) held the day preceding WTSA-12, 19 November 2012, acted on the recommendations of the CTO Group by taking SDN as one of its points of focus and feeding the conclusions of its SDN discussion into WTSA-12.

The workshop will take place at ITU Headquarters in Geneva, Switzerland, 4 June 2013, within the annual meeting of the ITU Telecommunication Standardization Advisory Group (TSAG), 4-7 June 2013. It will be co-chaired by Wei Feng, Huawei, China, Chairman of ITU-T Study Group 11 (Signalling requirements, protocols and test specifications); and Chae-Sub Lee, Kaist, Republic of Korea, Chairman of ITU-T Study Group 13 (Future networks including cloud computing, mobile and NGN). Confirmed speakers include representatives of ITU-T Study Groups 11 and 13; the University of Tokyo, Japan; MIIT/CATR, China; Cisco Systems; the ETSI Industry Specification Group on Network Function Virtualization (ISG NFV); and the Open Networking Foundation (ONF).
