Intro:
p2psim is a free, multi-threaded, discrete event simulator to evaluate, investigate, and explore peer-to-peer (p2p) protocols. p2psim runs in several UNIX-like operating systems. p2psim is part of the IRIS project.

Goals:
To make understanding peer-to-peer protocol source code easy, to make comparing different protocols convenient, and to have reasonable performance.

Because p2psim uses threads, implementations look like algorithm pseudo-code, which makes them easy to comprehend. p2psim supports several peer-to-peer protocols, making comparisons between different protocols convenient. p2psim maximizes concurrency for performance, minimizes the need for synchronization, and avoids deadlocks.

Disclaimer:
This is an alpha version of p2psim. We would value your feedback with suggestions and improvements.

Status:
p2psim already supports Chord, Accordion, Koorde, Kelips, Tapestry, and Kademlia. These implementations are specific to p2psim. They consist of substantially fewer lines of code than the real implementations.
