The interconnection network is often the critical component of a large multicomputer because the performance is very sensitive to network latency and throughput. To study the performance of existing and proposed network implementations, we conducts parametric simulation studies. Most modern multicomputer networks use wormhole routing. This thesis describes a methodology for the modeling and simulation of wormhole routing networks. This methodology is based on a framework called the DEVS (discrete event systems specification) formalism which supports modular and hierarchical specification of discrete event models. We use DEVSIM++, a C++ based modeling and simulation environment that implements the DEVS formalism. From simulation studies, topologies of interconnection networks, flit buffer size, and various routing algorithms of wormhole routing are performed, we propose a effective wormhole routing architecture.
