SIP benchmarks (2.4.0)

About the SIP test Scenario

To test the SIP performance of Rhino 2.4, we used a "Back-to-Back User Agent", or B2BUA, a common building block in SIP services. The test B2BUA is a simple routing B2BUA, that forwards SIP messages between two SIP dialogs, implemented as a SLEE service using the OpenCloud SIP resource adaptor.

OpenCloud chose the B2BUA service as a SIP benchmark because it is fundamental to many SIP applications. The B2BUA sits between the caller and the callee, maintaining SIP dialog state for each party, for the duration of the session. Many applications can be implemented by adding features on top of a generic B2BUA component (such as the test example) – so the performance of this B2BUA is a true indicator of how real-world B2BUA-based applications should perform.

The Rhino SDK distribution includes SIP examples of a B2BUA service and SIP RA.


Call flow


Measuring call setup time
The response time, or call-setup time, is the time taken between sending the initial INVITE (1) and receiving the 200 OK response (2), as measured by the UAC.

The Rhino SIP Benchmarks are run using SIPP 3.2.

The following scripts were used to run the scenarios:
