In this paper we consider the use of a fluid flow approximation based on ordinary differential equations (ODEs) derived from a model of a key distribution centre. The model is specified using the Markovian process algebra PEPA. The basic model suffers from the commonly encountered state space explosion problem when tackled using Markov chain analysis. Fluid flow analysis is therefore one possible mechanism for deriving approximate solutions for systems with large populations. The system is analysed numerically and results derived from solving the ODEs are compared with a queueing network approximation.
