Characterizing Reservation Management for Media Gateway Controller (Performance and Reliability)

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