(continuation of Q.7/17 studied during 2001-2004)
This Question is intended to provide protocols and service mechanisms for support of multi-service data networks (MSDN). Ethernet MAC, RPR MAC and other telecommunication channels have been deployed already and are continuing to develop all over the world. Multiple Service Ring based on RPR, is a multiservice Metro network technology that can also be used in various topologies. This Question addresses how to make use of these existing broadband resources effectively to provide multi-service data network applications. This Question provides the protocols and service mechanisms for MSDN. The new Recommendations will be suited for the existing multi-service data networks and various MAC (Ethernet, Gigabit Ethernet, RPR) engineering applications.
Existing Recommendations: X.85/Y.1321, X.86/Y.1323, X.87/Y.1324
This Question develops Recommendations with respect to protocols and service mechanisms for MSDN. The associated work will be handled and progressed in co-operation with other study groups, the IETF, IEEE 802, MEF, etc. The scope includes:
a) Maintenance of X.85/Y.1321 and X.86/Y.1323, Update and extension of X.87/Y.1324;
b) Progress draft Recommendation X.msr, including associated Ethernet/Gigabit Ethernet/10G Ethernet aspects;
c) Develop Requirements for MSDN, areas of study and development include:
d) Enhance existing packet protocols or, if required, develop new packet protocols to support the developed MSDN requirements, including service mechanisms;
- Identification of market needs
- architectural considerations, for L2 data networks;
- multi-service multicast aspects;
- Ethernet UNI and NNI aspects.
e) Develop associated MIBs (Management Information Base) to support item
- Maintain and/or extend current Recommendations
- New Recommendations according to the items under study.
Study Groups: ITU-T SGs 4, 11, 13 and 15
Standardization bodies: ISO/IEC JTC 1/SC 6; IETF; IEEE 802 Committee; and Metro Ethernet Forum
