A large-scale real-time network simulation study using PRIME

We examine the capabilities of conducting network experiments involving a large-scale peer-to-peer web-content distribution network. Our study uses a real-time network simulator, called PRIME, running on EmuLab, which is a shared cluster computing environment designed specifically for network emulation studies. Our study is one of the largest network experiments that involve a real implementation of a peer-to-peer content distribution system under HTTP traffic from a public-domain empirical workload trace and using a realistic large network model. Our experiments demonstrate the potentials of real-time simulation for studying complex behaviors of distributed applications under large-scale network conditions.
