Achieving robust fairness of SCTP extension for MPEG-4 streaming

In this paper, we introduce an extension of Stream Control transmission Protocol (SCTP) aiming for improving the efficiency of delay-sensitive transmission of multimedia data such MPEG-4 traffic. Briefly, our SCTP extension exploits one-way delay between SCTP endpoints, which allows the SCTP extension to retransmit lost packets selectively depending on whether the lost packets would still arrive before the schedule time. By computer simulations, we show that our extension provides the better performance than a simple retransmission method based on lifetime under both wired and wireless access links. Specifically, we confirm that our extension maintains the fair sharing of bandwidth among the legacy TCP flows, irrelevant to wired and wireless access links.
