p2psim: Roll Your Own P2P Protocol

Posted by ryuzaki0 on from the and-this-does-error-checking-and-this-is-the-31337-part dept.

Anonymous Coward writes "p2psim is a free, multi-threaded, discrete event simulator developed at MIT to evaluate and investigate p2p protocols. You can quite easily add your own p2p protocol and compare it with others to make sure it runs well before you write the real thing. p2psim runs in Linux and FreeBSD."

    I don't think I have ever seen or read anything that states that p2p is not legal. Maybe I'm just way behind the times, but it was my understanding that p2p itself is legal, it's what the network is used for that is illegal.

  2. Protocol Stub by Lizard_King · · Score: 4, Informative

    In addition to a cool sim, p2psim gives you a stubbed out protocol to play around with. Build your own and guage efficiency! Check it:

    protocols/sillyprotocol.h and protocols/sillyprotocol.C contain the outline of a new, but unimplemented peer-to-peer protocol. Implement join() and lookup() to your liking. Look at the other protocols (in the protocols/ directory) for more example code. Then run your SillyProtocol as follows:

    p2psim/p2psim example/silly-prot.txt example/silly-top.txt example/silly-events.txt

    Kudos to a great release and the promotion of additional research and general purpose learning.
