Aggressive transmission in the interconnected parallel banyan network

Abstract

The authors propose an improvement to the interconnected parallel banyan network (IPBN), a highspeed switching architecture for converged services networks. The IPBN design consists of multiple banyan networks with links provided at every stage to allow cell transfer to and from each plane, thereby offering multiple paths. The improvement makes use of an aggressive transmission scheme, which takes advantage of this multiplane architecture by sending out multiple copies of each cell. Using simulations, aggressive transmission in the IPBN is shown to offer better performance by way of lowering cell loss probabilities. Furthermore, the introduction of a skewing function in the distribution of cell copies to the IPBN's multiple planes resulted in even better performance in the way of further decreased cell loss probabilities.
