Aim of project is to build a Distributed File Server. A File server based on raft consenus protocol. This distributed file server is consist of 5 servers. Each have there own raft node and state machine. Project was accomplished in form of assignment where each assignment is one module of final File server.

In assignment I made a single file server. This file server takes command from client and execute them . File server supports operation of read, write, delete file . Besides this, file server also supports unusual operation like compare and swap and automatic deletion of file on basis of time expiry.

2. server.go

Assignment2 is about state Machine implementation. We were testing statemachine behivour through various event like AppendEntriesRequest, AppendEntriesResponse, VoteRequest, VoteResponse and timeout event were analyzing its output action for each event.

2. assign2_test.go

This was a wrapper to statemachine. In this assignment we integrate statemachine with its raftmachine. Here we implemnted 5 raftnode exchanging information, replicating data, electing leader. We also handled cases of partitions, leader's crashing

These 5 raftNodes are behaving concurrently and whole system will work untill majority of raft machine are in working state. #####Files Included

####Assignment4: This is integration of Raftamchine with file server of assignment1. Here we build a highly concurrent,fault tolerant distributed file server consisting of five file server which are behaving as one for client. #####Files Included
