Abstract	We develop a simulation model of the OSI Network Layer of packet-switching networks. We present the scope of our research and the need for simulation tools. We discuss the migration from an MS Windows interactive, real-time, GUI-based tool to two packages that can run under Linux. We describe aspects common to all serial execution versions that have been extensively used in a serial execution under the SHARCNET environment. Then, we focus on the porting to a parallel implementation. We examine and discuss alternate candidate solutions and their tradeoffs while converting the serial code to the parallel code. We discuss the parallelization of the code using pthread POSIX threading. Current work is targeted to design a model with a parallel architecture in mind from the outset.
