Enabling a Network Simulation Application on Grid Infrastructure

The advent of heterogeneous and distributed environments, such as Grid environments, made feasible the solution of computational intensive problems in a reliable and cost-effective way. We demonstrate the operation of a mechanism and evaluate its performance and effectiveness for the Network Simulation application in a Grid environment. The network simulator (ns-2), that was implemented, is used for simulation of high speed optical networks. In order to be able to meet the requirements of commercial business processes on the Grid, and especially network simulation tasks, we present a toolkit for centralized job submission and access. The approach has been implemented within the framework of the GRIA IST project that was originally designed for industrial based applications.
