The IMS/PES performance benchmark covers benchmark tests for the PSTN/ISDN Emulation Sub-system (PES), 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 following functional entities appear to be necessary from the perspective of specifying information flows and ensuring the interoperability of services:
- Access Gateway Analogue, BRI & PRI line function
- Residential Gateway Analogue & BRI line function
- Trunk Gateway function
- Access Call Server function
- Transit Call Server function
- Packet Handler Gateway function
- Media Gateway Controller function
- Media Server Control Function
- Customer Location function
- IN Access Subsystem
- SIP Server Access Function
- Trunk Signalling Gateway
A benchmark test may 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 provider’s requirements that the result of the test can be used as an estimate of the performance of their deployed system).
IMS / PES Performance Benchmark accordance with new ETSI standard TS 186 025 pre-written scripts:
- ISDN - ISDN (A<->A, A<->B)
- PSTN - ISDN (A<->A, A<->B)
- PSTN - PSTN (A<->A, A<->B)
- SIP - SIP (A<->A, A<->B)
- SIP - ISDN (A<->A, A<->B)
- SIP - PSTN (A<->A, A<->B)
In order to accomplish these goals, a suite of benchmark tests must cover a range of scenarios that are representative of the real world. Given the early nature of the IMS/PES deployments, the data required to construct these scenarios is still in the process of being collected. For that reason, the benchmark test described here is more useful for prediction than for comparison.
Network Operators who want equipment in their labs to check the performance of equipment / networks with various loads. In particular Interoperability between various equipment.
Interoperability has become an increasing problem with so many equipment suppliers / standards / implementations - confidence in the network not to crash / drop calls under many load conditions must be tested.
Cost effective equipment to test upto 4000 POTS / 1000 BRI-U, BRI-S, PRI interfaces means that the system can be expanded as the network grows.
