- Abstract
There are multiple paths between pairs of multihomed source and destination hosts. However, some Stream Control Transmission Protocol (SCTP) versions always try to use the best available path and funnel all traffic onto it, leaving the remaining ones for redundancy. We investigate fair rate allocation for flows on paths in best path transfer (BPT) using SCTP multihoming. Firstly, path capacity is defined and the common paths shared by several different sources are considered. Based on the idea of network utility maximization (NUM), the rate allocation model for BPT is presented, in which path reputation is used as a novel metric for the best path selection. In order to obtain the optimum of our model, two distributed algorithms are presented, and different fairness concepts can be achieved among competing sources if different utility functions are chosen accordingly. Simulation results confirm that the proposed algorithms can achieve the global optimums within reasonable convergence times.
