scope:

This Recommendation 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 this Recommendation include:

• traffic set;
• traffic-time profile;
• benchmark test procedure.
