Abstract

This paper examines the performance for the integrated voice and data services in hybrid fiber/coax (HFC) networks through mathematical analysis. Ourobjective is to obtain the feasible region (FR) for the integrated services subjected to their packet level quality-of-service (QoS) requirements. The analysis is focused on the upstream channel and the performance of the system is evaluated in terms of voice packet loss probability and the mean data message delay. Two different service classes are provided for voice. Thevoice packet loss probability is independent of data traffic and an elaborate discrete-time Markov chain model is developed, The data traffic is modeled as a batch Poisson arrival model. Two schemes are considered for data: with or without bandwidth reservation. The integrated voice and data systems are analyzed using the matrix-analytic method. Numerical examples are presented to demonstrate the performance of such a proposed integrated voice and data system. (C) 2001 Elsevier Science B,V. All rights reserved.
