Delay Analysis in Computer Communication Systems

Abstract

In this paper, we propose a seemingly efficient method computing the delay distributions in computer communication systems including switching system. The proposed method is based on GPH (Generalized Phase-Type) distributions which are the distributions of random sum of i.i.d. exponential random variables. The class of GPH distributions has several properties which can be applied conveniently for computational purposes. This basic methodology adopted in delay analysis for switching system is explained step by step. Application results are given to demonstrate the accuracy of the method and to verify that the system meets the requirements of delay. The propose method seems to be very useful to analyze delay performance in computer communication systems.
