This project enables Simple Window-based Reliable Data Transfer in C/C++. It utilizes Go-Back-N protocol to achieve reliable data transfer on top of UDP socket and uses json11 for packet serialization.
This project requires the complier to support C++11. Here is a guide to update gcc on ubuntu.
In the root directory, run make command in the terminal.
This will generate two folders, server_folder and client_folder, as well as two programs server and client inside them.
Inside server_folder, run
> server < portnumber > [ CWnd Pl PC ]
This will run the server program and wait for requests on the portnumber specified by the user.
Inside client_folder, run
> client < server hostname >< server portnumber >< filename > [ Pl PC ]
This will run the client program which first tries to handshake with server and then requests the file in server_folder specified by filename.
The parameters in [ ] are optional. Cwnd is the window size which is default to 5. Pl is the probability for packet loss and Pc is the probability for packet corruption from 0 to 1.
