New strategy of improving stream control transmission protocol performance over satellite link

Due to the advanced and unique features of multi-homing and multi-streaming, Stream Control Transmission Protocol is suitable for data communications over satellite network, however, the satellite network are characterized by long-propagation delays, large-bandwidth product, and corruption losses. Thus, these protocols (TCP, UDP, SCTP) doesnpsilat work better over the satellite link. In this paper, we propose a new strategy including Load sharing strategy and a new congestion control mechanism which aim to improve the performance of SCTP over satellite links. The effective of the proposed strategy is discussed and confirmed through experimental evaluations. The proposed strategy is implemented on the NS2 (Network Simulator Version 2.26) with an SCTP module. Simulation results demonstrate that the performance of SCTP is significantly improved.
