Performance analysis of token rings as high speed backbone networks

Abstract

Results of a performance analysis are presented for several token ring protocols in a backbone environment; the fiber distributed data interface (FDDI) and the exhaustive service and the single-service broad site wideband networks for a reduced speed of 100 Mb/s. The operation of the protocols is studied in detail with respect to several performance parameters like percentage of token use or number of packets transmitted per token capture. For performance comparison, queue length as well as packet and file delay is considered. Every media access protocol under consideration is shown to work very well for typical numbers of stations ( >
