Optimized flow division modeling for multi-path transport

Multipath Transport Protocols like Stream Control Transmission Protocol (SCTP) and Multipath TCP (MPTCP) support concurrent usage of multiple paths between the end users. In this paper we investigate the flow division at the source among multiple paths as an optimization problem. We also introduce link-by-link error recovery scheme and compare the system performance when the traditional end-to-end error recovery approach is adopted. The optimization objectives also depend upon whether the supported application is delay sensitive or delay insensitive in nature.
