Methods for the Analysis of Node-in-isolation Models

Abstract

As pointed out in Chapter 2, a LAN or a MAN station is frequently analyzed in isolation and hence each station is modeled as an M/G/l queueing system with or without server vacation (node-in-isolation models). This chapter presents methods extensively used in the literature to analyze the performance figures of these systems. Specifically, it focuses on the study of the stochastic process {N(t),t≥0} which represents the number of packets queued in the system (e.g., a station of a MAN, a packet-switching node, etc.) at a random point in time.
