Modified Stream Control Transmission Protocol over Broadband High Latency Networks

Stream Control Transmission Protocol (SCTP) is newly emerged protocol, which is combination of good qualities of TCP and UDP. It is a reliable message oriented protocol providing multistreaming and multihoming. In this paper, a modified algorithm is proposed for dealing multiple packet losses which improves congestion control mechanism in network. Proposed SCTP is a simple sender side alteration to the SCTP congestion window update algorithm with same traditional SCTP receiver. The results are compared with traditional SCTP and Scalable SCTP traffic using Network Simulator-2 and result is better than the other schemes.
