Abstract

Recent research on Concurrent Multipath Transfer (CMT) and CMT with a Potentially-Failed destination state (CMT-PF) uses the transport layer multi-homing protocol Stream Control Transmission Protocol (SCTP) to increase application throughput by distributing transmitted data across multiple end-to-end paths. This paper investigates and evaluates the performance of CMT with Partial Reliability (CMT-PR) and CMT-PF with Partial Reliability (CMT-PF-PR), novel extensions of SCTP for real-time video distribution. The Evalvid-CMT platform was implemented in the University of Delaware's SCTP/CMT ns-2 module to perform emulation experiments in order to compare CMT and CMT-PR, CMT-PF and CMT-PF-PR,respectively. The results presented in the paper show how the CMT-PR and CMT-PF-PR outperform CMT and CMT-PF respectively. Consequently the former are suggested as strategies for real-time video concurrent multipath transmissions.
