15.1 Introduction
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 impos-
sible to analyze the low-level performance, or the effect of new scheduling,
replication, and organizational algorithms on actual test-beds. As such,
practitioners turn to simulation tools to allow them to rapidly evaluate
