Abstract
Buzz-net is a local network supported by a pair of unidirectional buses to which stations are connected via passive interfaces. The access protocol is a hybrid which combines random access and virtual token features. More precisely, the network operates in random access mode at light load and virtual token mode at heavy load. Because of the virtual token implementation, Buzz-net retains high efficiency even at very high bus speeds. Efficiency at high speeds and bus unidirectionality make Buzz-net particularly suitable for fiber optics media. This paper describes the protocol, develops approximate analytic models for performance evaluation, and compares Buzz-net performance results to those of other unidirectional bus schemes.Keywords
