Performance analysis of nonblocking packet switch with input and output buffers

Abstract

The performance of nonblocking packet switches such as the knockout switch and Batcher banyan switch for high-speed communication networks can be improved as the switching capacity L per output increases; the switching capacity per output refers to the maximum number of packets transferred to an output during a slot. The N*N switch with L=N was shown to attain the best possible performance by M.J. Karol et al. (1987). Here a N*N nonblocking packet switch with input and output buffers is analyzed for an arbitrary number of L such that 1<or=L<or=N. The maximum throughput and packet loss probability at input are obtained when N= infinity .<<ETX>>
