Paper Abstract

Design and analysis of ATM networks in which sources are represented as fluid on/off is addressed. It is critical that cell loss rate as an important QOS measure be related to the call blocking, an important network design parameter, and this relation be used in link capacity sizing, call admission, and routing design. Recently, some research on the relation of cell loss and call blocking have appeared. However, they ignore buffering in the multiplexer. In this paper, it is shown that call blocking in a buffered ATM multiplexer behaves as an Erlang-B loss system. For analytic purposes system buffer is assumed infinite and transmission rate of the link (C) is assumed to be finite. Using past results on probability of cell loss and properties of Nearly Completely Decomposable Markov Chains, the aggregate cell loss when system is in different states is determined. It is shown that call blocking performance for a given link capacity is independent of the individual source parameters. An extended set of application of the results and an inverse problem is stated.
