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 acknowledgment loss. In this work, a modified algorithm for MPSCTP is proposed to mitigate this limitation and its performance is compared 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. This paper also presents 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.
