Meeting at ITU headquarters in Geneva, ITU-T Study Group 11 Ė Protocols and test specifications Ė received 72 participants from 22 countries, representing a 53 per cent increase over the participation numbers recorded for its previous meeting in June 2012.
The meeting saw substantial progress made in ITUís collaboration with the Open Geospatial Consortium (OGC) and also advanced the groupís ongoing work on software-defined networking (SDN) and conformance and interoperability (C&I) testing. Read news on the meeting's C&I achievements here.
OpenGeoSMS is a standard maintained by OGC, originally developed by the Industrial Technology Research Institute (ITRI). Study Group 11 continues to collaborate with OGC with a view to formalizing OpenGeoSMS as an international standard (ITU-T Recommendation). The standard uses Short Message Service (SMS) to exchange location-based information and is considered particularly important in providing relief to individuals affected by natural disasters.
Expanding and accelerating standardization work on software-defined networking (SDN) was one of the key directives issued by ITUís membership at last Novemberís World Telecommunication Standardization Assembly (WTSA-12) in Dubai.
In the interests of greater speed and flexibility in routing instructions, security and energy management of network equipment such as routers and switches, SDN proposes to decouple the control and data planes and allow for programmable interfaces to these planes; letting software do the job traditionally performed by the control plane.
ITUís standardization work on SDN started in ITU-T Study Group 13 Ė Future networks including cloud computing, mobile and next-generation networks. SG 13 standardizes SDNís functional requirements and architectures, and SG 11 thus works closely with SG 13 as it builds on this work by developing SDNís signaling requirements and protocols.
SG 11ís recent meeting in Geneva received contributions calling for new SDN work items, including:
- Scenarios and signaling requirements for software-defined BAN (SBAN)
- Framework of signalling for SDN
- Scenarios and signalling requirements of unified intelligent programmable interface for IPv6
The next meeting of SG 11 is scheduled to take place in Uganda, 6-15 November 2013, in collocation with the next meeting of SG 13 to strengthen the collaboration between these groups.
