Prerequisites

• Java-8
• MultiThreading and Socket Programming
• Basic Data Structures and Protocol understanding

Description:

Implement the Jajodia-Mutchler voting algorithm. Let there be eight servers, A, B, C, D, E, F, G, and H. There is only one data object X, replicated across the eight servers, that is subject to writes. Initially, the version number (VN), replicas update (RU) and distinguished site (DS) values for X at all servers are 1, 8, and A, respectively. The rule for selection of distinguished site favors the server that is alphabetically smallest among the candidates.

For Further Details read Project3.pdf

Requirements for the Project

1. You must attemp at least two writes in each of the network components show in Figure 1. A write can originate at any of the servers in the corresponding partition.
2. After each write attempt, successful or unsuccessful, output the VN, RU, and DS values for each server

Important Note

Current Implementation does not handle multiple requests at once. For Crash Failures read the Research paper to implement Make_Current Method.
