Foreword This T

28、echnical Specification (TS) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). The present document is part 2 of a multi-part deliverable covering the IMS/NGN Performance Benchmark, as identified below: Par

29、t 1: “Core Concepts“; Part 2: “Subsystem Configurations and Benchmarks“; Part 3: “Traffic Sets and Traffic Profiles“; Part 4: “Reference Load network quality parameters“. ETSI ETSI TS 186 025-2 V2.2.1 (2011-06)61 Scope The present document is for an initial release of a PSTN/ISDN Emulation Sub-syste

30、m (PES) performance benchmark. The same tests can be used also for legacy PSTN/ISDN networks or for inter-working tests between PSTN/ISDN emulation subsystem and legacy PSTN and ISDN. The metrics measured and reported are for performance of this subsystem under a communications application load. The

31、 present document is the second part of the multi-part deliverable which consists of four parts. TS 186 025-1 1 contains the overall benchmark descriptions, architectures, processes, and information models that are common to all specific benchmarking scenarios. The present document contains the spec

32、ific benchmarking use-cases and scenarios, along with scenario specific metrics and design objectives. It also defines the SUT configuration parameters. This part also contains any required extensions to the overall descriptions present in the present document, if necessary for the specific scenario

33、. TS 186 025-3 i.1 defines an initial benchmark test through the specification of a traffic set, traffic-time profile and benchmark test procedure. TS 186 025-4 i.2 defines Reference Load network quality parameters for the use cases defined in the present document. 2 References References are either

34、 specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies.
