Lightnet: a protocol for future real time high speed broadcast networks

A set of high-speed protocols working on unidirectional broadcast systems is defined. Lightnet 1 is based on collision avoidance and a simple reservation scheme; Lightnet 2 is a version for heavy loads; and Lightnet 3 is designed to work on a ring topology. Three analytical models are developed to evaluate the performances of these protocols. Comparisons between analytical and simulation results show the accuracy of these models. A careful comparison between Lightnet I and Expressnet shows that the former outperforms the latter both for average delay and for flexibility to various kinds of traffic mixes under the assumption of uniform packet size.<
