Large-Scale Network Simulations of Internet Distributed Systems

The design and evaluation of large distributed systems such as peer-to-peer networks and anonymous networks are difficult. Analytical models are insufficient, thus high-fidelity simulations are required. This research group’s Distributed Virtual Network simulator is able to run such simulations by using the actual protocol code ported from existing overlay network nodes. The main limitation is memory consumption, since each overlay node was originally built to run on a stand-alone machine. The researchers intend to scale up their simulation to current internet scale (over a million virtual nodes) and beyond to characterize the network behavior under current and future loads. They will also study the network under multiple attack scenarios that the system was built to resist, but for which no analytical model exists.
