Abstract

Research presented in this paper uses the Network Simulator, ns2, to investigate the direct effects and subsequent consequences associated with the use of different transport protocols in a SIP context. Specifically, we seek to perform a comparative evaluation of UDP, TCP and SCTP based on a model simulating a scenario most likely to benefit from congestion control and error correction mechanisms associated with the reliable transport protocols. The overall aim of this paper is to make a contribution to the information available for the appraisal of such protocols in respect of real world implementations.
