P2P File Sharing

Overview

P2P file sharing software. Peers share handshake and bitfield messages with each other when a connection is formed. After, the peers use choke, unchoke, request, have, piece, interested, and not interested messages to distribute the data to all peers in the network.

Completed Features

We completed all features outlined in the document. All messages are sent and received properly. Peers will choke and unchoke based on the unchoking interval and optimistic unchoking interval. Peers will send interested and not interested messages based on the info they have about other peers' bitfields. Major operations are logged in the respective log files.

Compilation & Running Instructions

To compile, run the following command in p2p-file-sharing/src:

javac ChokeHandler.java MessageHandler.java Peer.java Client.java Log.java Server.java peerProcess.java

To run, run the following command in p2p-file-sharing/src:

java peerProcess <peerId>

Ex. java peerProcess 1001

NOTE: peerId must match a peer in p2p-file-sharing/src/config/PeerInfo.cfg
