Abstract

We propose the neighbor-state based queuing (NBQ) for improving the performance of flows sharing link bandwidth under various transfer protocols. Each router with NBQ informs the next upstream router of its link status. According to the received status, the NBQ dynamically sets the packet discard ratio of the non-adaptive flows. The NBQ reduces the wasted non-adaptive flows and provides available bandwidth for the adaptive flows. We have demonstrated dramatic improvements of the adaptive flow´s throughput using our scheme through simulations.
