Abstract

Web-Services based Service-Oriented Architectures (SOAs) become ever more important. The Web Services Reliable Messaging standard (WSRM) provides a reliable messaging layer to these systems. In this work we present parameters for acyclic continuous phase-type (ACPH) approximations for message transmission times in a WSRM implementation confronted with several different levels of IP packet loss. These parameters illustrate how large data sets may be represented by just a few parameters. The ACPH approximations presented here can be used for the stochastic modelling of SOA systems. We demonstrate application of the models using an M/PH/1 queue.
