Conformance & Interoperability
Current status
In WTSA08, Resolution 76 “Studies related to conformance and
interoperability testing, assistance to developing countries was
approved which instructs all Study Groups to take actions to
improve NGN interoperability.
Since 2006, SG11 has developed Recommendations Q.3900
series for test specification. Currently 28 recommendations has
been published. Study on developing test specifications was
accelerated by Resolution 76 and continuing in this study period.
SG11 Action plan on implementation of C&I Program (TD70/GEN11) was approved in SG11 meeting (February 2013) and
LSs was sent to requests to all ITU-T SGs on developing test
requirements for their current/future Recommendations.
Interoperability events based on the ITU-T Q.3900 series were
proposed to be held by regional SDOs in order to help the
capacities building in developing countries. The principle of this
proposal was agreed in the previous SG11 meeting (February
2012 Geneva), and endorsed by TSB (May 2012).
Resolution 76
approved in WTSA08 and revised in WTQA12
Studies related to conformance and
interoperability testing, assistance to
developing countries[1], and a possible
future ITU Mark programme
(Johannesburg, 2008; Dubai, 2012)

countries to implement the conformity /
interoperability assessment in the Region taking
into account international approaches, best
practices and requirements. [ 70-GEN ]

New work items on SDN
The following WIs on SDN was approved in the SG11 meeting.
Supplement-SDN framework of signalling for Software
Defined Networking
Q.SBAN Scenarios and signaling requirements for softwaredefined broadband access network (SBAN)
Q.IPv6UIP Scenarios and signalling requirements of unified
intelligent programmable interface for IPv6
The U.S. expressed concerns that the development of signalling
interfaces and protocols should not be started before the
functional architecture and functional entities are defined. The
U.S. expressed reservation to these new work items.
Close collaboration is required between SG11 and SG13
to harmonize their works.

Conclusion
SG11 produced various Protocols for resource, session, service control and multicast communication etc. SG11 is the lead SG of test specifications and conformance and interoperability testing. SG11 will study protocols and test specifications for new service and new network e.g. NGN enhance, IoT, M2M, Cloud computing, IPv6 etc. SG11 would take the lead coordinating role in the harmonization of various protocol standards based on the concept of consistent end‐to‐end interoperability.
