Performance of Segnet — a simulation study

Abstract

This paper describes the performance evaluation of Segnet, a CSMA/CD-based protocol with dynamic network segmentation. Segnet is shown to be suitable for network environments where the traffic pattern is highly localized into groups of stations clustered together. Some further improvements in performance are also shown to accompany the incorporation of store-and-forward buffers in Segnet stations. This is because degradations in performance caused by the segmenting of the network are minimized by temporary storage of packets which would otherwise have to be abandoned.
