Research on Analysis and Simulation of SCTP

Stream Control Transmission Protocol(SCTP) is a new transport layer protocol recommended by the IETF.It reserves some characteristics of the traditional TCP protocol,and also develops its distinct features: multi-streaming and multi-homing.With these advantages,SCTP can meet the needs of the fast developing communication networks,and has a trend to replace the traditional transport layer protocols in some areas.The features and function modules of SCTP are firstly introduced,based on the traditional transport layer protocols.Then,simulate the failure network and compare the fault tolerance of SCTP with TCP during the multi-homing host peers by using NS2 software.Simulation results show that only SCTP could handover transmission automatically on the other activated path when the primary path is broken down,and SCTP with the feature of multi-homing has apparent performance advantages on robustness.
