Abstract:
This paper introduces DSCTP (Dynamic Stream Control Transmission Protocol), a sender-side, transport-layer protocol that modifies the standard Stream Control Transmission Protocol (SCTP) protocol. Although SCTP provides support for multi-homing,the basic reason for such a provision was to improve reliability of associations, simultaneous transfer of new data to multiple paths is currently not allowed in SCTP. DSCTP adopts SCTP’s multi-homing feature to distribute data across multiple end-to-end paths in a multi-homed SCTP association. DSCTP aims at exploiting congestion control algorithm of Transmission Control Protocol (TCP) and SCTP. Through the use of dynamic policy management framework, DSCTP switches the transmission onto the alternate path using DSCTP’s flexible path management capabilities. We can gain significant throughput improvement if simultaneously transfer new data across multiple paths to the receiver. In this article,these techniques include transmission start, flow control, network monitoring, generation of policies, routing switching, and congestion recovery. Extensive simulations under different scenarios highlight the superiority of the proposed solution with respect to TCP and the standard SCTP implementation.
