Signalling Transport Protocols

SCTP is a newly developed transport protocol tailored for signalling transport. Whereas in theory SCTP is supposed to achieve a much better performance than TCP and UDP, at present there are no experimental results showing SCTP’s real benefits. This paper analyzes SCTP’s strengths and weaknesses and provides simulation results. We implemented SIP on top of UDP, TCP and SCTP in the network simulator and compared the three transport protocols under different network conditions.
