Abstract :

In this paper, analysis and simulation of Media Gateway Controller (MEGACO) based COPS (Common Open Policy Server) which is a protocol defined in IETF (Internet Engineering Task Force) to transport configuration requests and deliver the policies is presented. For this scenario, three queuing models include M/M/1, M/M/c and M/D/c were applied . Then, some of the key performance benchmarks look likes mean response time to process the MEGACO calls and mean number of MEGACO calls in the system was reviewed. In the following, the comparison between them was performed.
