Packet Trains: Measurements and a New Model for Computer Network Traffic.

Abstract

Traffic measurements on a ring local area computer network at Massachusetts Institute of Technology are presented. The analysis of the arrival pattern shows that the arrival processes are neither Poisson nor Compound Poisson. An alternative model called packet train is proposed. In the train model, the traffic on the network consists of a number of packet streams between various pairs of nodes on the network. Each node-pair stream (or node-pair process, as we call them) consists of a number of trains. Each train consists of a number of packets (or cars) going either direction (from node A to B or from node B to A). The inter-car gap is large (compared to packet transmission time) and random. The inter-train time is even larger. The Poisson and the Compound Poisson arrivals are shown to be special cases of the train arrival model. Keywords: Computer Communications; Land transportation; and Rail transportation.
