On Incorporating Differentiated Network Service into GridSim

Grid computing technologies are increasingly being used to aggregate computing resources that are geographically distributed across different locations. Commercial networks are being used to connect these resources, and thus serve as a fundamental component of grid computing. Since these grid resources are connected over a shared infrastructure, it is essential that we consider their effect during simulation. In this paper, we discuss how new additions to the GridSim simulation toolkit can be used to explore network effects in grids. We also investigate techniques to incorporate differentiated service, background traffic and collecting information from the network during runtime in GridSim. As a result, these features enable GridSim to realistically model grid computing experiments
