Improving of Load-Balanced Self-Routing Switch by Network Code

Recently, a novel switch architecture is proposed to provide more scalable and lower delay service for the internet applications. But the structure is blocking and based on packet dividing. It causes serious performance degradation for most variable-sized packet switch application. In this paper, a new network code scheme is proposed to improve the packet loss performance of a two stage load-balanced structure based on concentrators. Analysis and simulation show that this network code scheme obviously cut down the packet loss of Load-Balanced Multi-path Self-routing switch while keeping the other good features of this structure.
