Performance evaluation of SIP infrastructure

The paper deals with performance measurement and assessment of SIP based network. The complex methodology for SIP benchmarking and performance testing based on IETF draft versions has been developed by our team so that the results coming from the measurement specified in this methodology could be compared platform independently. Our earliest implementations of this methodology relied on open-source software and virtualization tools and were greatly improved during the last year with the emphasis on ease of use, understandability and repeatability. The development of this platform and its current stage are the topic of this paper which presents both the cornerstone technologies of the new platform and the main aspects of the methodology in relation to the result analysis.
