Flow Networking in Grid Simulations

Abstract

Simulation tools play an essential role in the evaluation of emerging peer-to-peer, computing, service and content delivery networks. Given the scale, complexity and operational costs of such networks, it is often impossible to analyse the low-level performance, or the effect of new scheduling, replication and organisational algorithms on actual test-beds. As such, practitioners turn to simulation tools to allow them to rapidly evaluate the efficiency, performance and reliability of new algorithms on large topologies before considering their implementation on test-beds and production systems.
