ETSI ETSI TS 186 008-3 V2.1.1 (2015-06)5 1 Scope The present document defines initial benchmark tests through definitions of traffics sets and traffic profiles. The benchmark is defined for the IMS network as a whole, as well as for s
17、everal 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. 2 References 2.1 Normative reference

31、ng and executing an IMS performance benchmark. The present document specifies a benchmark test, which may be implemented and performed as-is, or which may serve as an example for future benchmark tests developed by a service provider or SUT implementor. 4.1 Benchmark test goals A benchmark test may
32、be used either for comparison (e.g. comparing the performance of two products), or for prediction (e.g. the configuration specified for a benchmark test is similar enough to a service providers requirements that the result of the test can be used as an estimate of the performance of their deployed s
33、ystem). ETSI ETSI TS 186 008-3 V2.1.1 (2015-06)7 4.2 Initial benchmark traffic set and traffic-time profile As described in details in ETSI TS 186 008-1 1, a benchmark test measures the behaviour of a SUT for a specified traffic set and traffic-time profile. A traffic set is composed of a mixture of
34、 test scenarios, whose relative frequency of occurrence is specified by traffic set parameters; the traffic-time profile is a specification of how the average arrival rate of test scenarios evolves over the execution of the benchmark test. Tables 1 and 2 represent a generic IMS/PES traffic set and p

The percentage of System Load for each scenario has not been defined, because the load depends on the number of selected use cases.
