Abstract

The Stream Control Transmission Protocol (SCTP) has been developed as a reliable transport layer protocol for carrying PSTN signalling messages over IP networks. However, its advanced congestion control and fault tolerant features make it a strong competitor to the widely used TCP protocol. In this paper, we investigate the performance of SCTP in an error-prone network, and compared it with that of TCP. We have found that the performance of SCTP is higher than that of TCP for a range of wireless error probabilities. We have shown that differences in the retransmission mechanisms of the two protocols leads to the better performance of SCTP.
