Abstract :
SCTP has been found to perform poorly performance in the presence of spurious timeouts (ST) caused by delay spikes which are especially frequent in today´s wireless mobile networks. Spurious timeouts cause unnecessary retransmission for several segments and congestion control back-off. There are some proposals for avoiding unnecessary retransmissions after a spurious RTO for require use of SCTP options. We introduce a new SCTP sender algorithm for recovery after a retransmission and show that unnecessary retransmissions can be avoided without SCTP options. The algorithm effectively avoids the unnecessary retransmissions after a spurious RTO, improving the SCTP performance considerably.
