Description / Abstract:

This Recommendation specifies the management aspects of performance measurement. Its scope is as follows:

– Requirements for management of performance measurement.

– A reference measurement network model as an extension of clause 8 of [ITU-T Y.1543], which allows for various measurement scenarios for NGN.

– A general and functional architecture for the management of performance measurement and the related stage-2 requirements.

– Management procedures covering various management scenarios such as discovery of measurement entities, initiation of measurement and exchange of measurement data among different NGN domains.

– Application scenarios for management of performance measurement (MPM) use cases such as procedures for performance measurements, degradation resolution and RTP/RTCP-based performance notification.

Note that the pertinent protocol specifications for reference points and procedures are expected to be described in separate Recommendations.

This Recommendation also describes the following MPM use cases:

1) Performance degradation resolution information reporting.

2) RTP/RTCP-based performance notification.
