Summary

Recommendation ITU-T Q.3932.3 provides the third part of a multi-part deliverable covering the IMS/NGN performance benchmark, as identified below:

Part 1:   Core concepts;

Part 2:   Subsystem configurations and benchmarks;

Part 3:  Traffic sets and traffic profiles;

Part 4:   Reference load network quality parameters.

The metrics measured and reported are for the performance of this subsystem under a communications application load.

The benchmark is defined for the IMS network as a whole, as well as for several subsystems of an IMS network. The benchmark is designed so that nodes composing a subsystem can also be benchmarked alone.

The initial benchmark test data defined in the present document include:

•            traffic set;

•            traffic-time profile;

•            benchmark test procedure.
