Sub-path congestion control for Concurrent Multipath Transfer

We proposed a sub path congestion control principle for SCTP (SPCC-SCTP) with bandwidth-aware source scheduling by dividing an association into sub paths based on shared bottleneck detection to overcome existing flaws of standard SCTP in supporting the multi-homing feature in the case of Concurrent Multipath Transfer (CMT). The performance of the SPCC-SCTP is assessed through ns-2 experiments in a simplified Diff-Serv network. Simulation results demonstrated the effectiveness of our proposed mechanism and invite further research.
