An Optimal SACK Scheduling Mechanism for Concurrent Multi-Path Transport Schemes

Up to now, the most concurrent multi-path transport (CMT) schemes mainly aim at the issues caused by forward transmission like data reordering at receiver side and neglect the studies on impact of reverse paths' transmission delays. This paper proposes a SACK scheduling mechanism for the CMT schemes to accelerate data transmission in multi-homing environment, in this scheme, the most SACK chunks will be sent via an optimal reverse path. Simulation results show that the proposed scheme can significently improve the transmission efficiency of the CMT schemes in some cases.
