EXPERIENCES OF USING THE PEPA PERFORMANCE MODELLING TOOLS WITH A NON-REPUDIATION PROTOCOL

摘要

In this paper, we described a experience of using PEPA eclipse plug-in tool to specify a functional-equivalent representation of a non-repudiation protocol. The model is specified using Markovian process algebra PEPA. The basic model suffers from the well known state space explosion problem when tackled using Continues Time Markov Chain analysis. In order to modelling in a scalable way, functional rates has been adopted to avoid a unintended system behaviour. The functional rates have been specified in a CMDL (Chemical Model Definition Language) format which equivalently generated from the PEPA model by PEPA eclipse plug-in. This representation has been converted back to PEPA expression, and analyzed numerically.
