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...
The Session Initiation Protocol currently supports the use of both the Transmission Control Protocol and the User Datagram Protocol as transport protocols. Proponents of the SIP protocol have cited this characteristic as a laudable consequence of the modular nature of SIP. However, the explicit support of an unreliable protocol such as UDP leads to, arguably, unnecessary complication in the protocol...
