报告摘要：In the literature, Multipath Stream Control Transmission Protocol (MPSCTP) has been proposed as a multipath variant of Stream Control Transmission Protocol (SCTP). Unlike SCTP, MPSCTP uses the multiple available paths between the source and the destination in concurrent fashion, using the multihoming feature of SCTP. MPSCTP in its original form implicitly assumes no acknowledgement loss. We present modified algorithms for MPSCTP and other related protocols to mitigate this limitation and compare their performance with Concurrent Multipath Transfer (CMT) using ns2 based simulation. A new path selection strategy for data transmission is incorporated and its results are compared with the RTX-CWND strategy proposed in the literature. We also present a heuristic to implement delay insensitive optimization. The performance of this optimization for MPSCTP has been studied using ns2 based simulations. We have also presented the performance results of MPSCTP implementation in the Linux Kernel. We also discuss the problem of optimizing the flow division for multipath transport.
