(continuation of Q.10/4)

Motivation

Using the management interface specification methodology in Recommendation M.3020 and the generic information models, an initial set of network technology-specific management interfaces have been specified in the form of protocol-neutral and protocol-specific information models to support identified requirements. These information models have involved different levels of management abstractions (example network level, service level), various management functionality (example alarm reporting), support for specific technologies including transport (e.g., Ethernet), access (e.g., PON), and core network (e.g., signalling and packet switching network elements).

The models developed prior to 2000 were based only on specific protocols, but subsequently protocol-neutral information models have been required as well. Protocol-specific models using CORBA and increasingly XML-based web services are now preferred for these specialized information models.

Question

Study items to be considered include, but are not limited to:

• What Recommendations are required to define network level requirements and protocol-neutral and protocol-specific information models for specific broadband technologies of transport and access networks?
• What Recommendations revisions are needed to define requirements and information models to support the management of ASON and Ethernet at the network level? This may include enhancements to the M.3170 series to support the TMF MTNM enhancements concerning network level ASON and Ethernet management. It is assumed that SG15 is responsible for ASON and Ethernet network element information model?
• What associated management requirements and information are needed to specify a service level information model supporting management activities over management interfaces?
• What modifications and extensions to specialized requirements and management information models in existing Recommendations are needed to support NGN?
• What specialized information models are required in support of B2B and C2B management interfaces?
• What specialized requirements and information models are needed in support of customer control?
• What enhancements to specialized requirements and information models are needed to support IPTV, Home Networks, and Identity Management?
• What collaboration inside and outside the ITU-T is required to support the generation of specialized requirements and information models?
• What maintenance of existing Recommendations is required?

Tasks

Tasks include, but are not limited to:

• Develop requirements and protocol-neutral and protocol-specific information models to support the management of the NGN transport stratum (transport and access network technologies) in collaboration with other organizations.
• Enhance the M.3170 series to support network-level ASON and Ethernet management in collaboration with the TM Forum and MEF.
• Develop protocol-neutral and protocol-specific information models to support the management of the NGN service stratum, including support for the M.3340 series and M.3350 series of Recommendations.
• Maintain Q.751, the Q.820 Series, the Q.830 series, the Q.840 series, and the M.3600 Series.
