A Crosslayer Concurrent Multipath Random Forward Algorithm

The rapid development of next generation network (NGN), communication technology and programming router in the last few years have given rise to a strong research interest in concurrent multipath (CMP) technology. Based on the analysis of flow relation and forward granularity, a novel network layer CMP forward algorithm, CCRF (crosslayer CMP random forward), is proposed. CCRF can classify different paths and different flows and forward packets concurrently, NS2 simulations prove that CCRF reduces the degradation of different paths performance and achieves a better performance of throughput and delay and it is easily deployed into the programming router.
