Peer2Peer is a simple application built using socket programming in C++ which is capable of transferring files over TCP. Since TCP is used file verification(hashing) is not considered.

The P2P communication is achieved by two threads running under a main thread. One thread acts as a server and other thread acts as a client running under a single process. Thus if a new process is started it can communicate with each other. The hostname and port is needed to make the connection.

P2Pmain.cpp: The main startup file, resposible to create two threads.

PeerReceiver.cpp The peer receiver or the server thread, resposible to accept and provide files to other peers.

PeerSender.cpp The peer sender or the client thread, resposible to connecte to other peers and give commands to download specific file.

Go to the Debug folder and run make all to compile make clean to clean

A sample test is provided under the “Test” folder. The Test directory contains a simple structure of a P2P setup with 2 peers, Peer1 and Peer2. Each of them have a shared directory named, shared. Each of them have a executable named PeerToPeer which can be used to create a connection between each other.

The compiler warnings need to be fixed Error and Exception handling can be improved More test case and different file format need to be tested. Unit test case addition
