Content-Addressable-Network

A P2P hash table based network system.

Introduction

This CAN system is implemented by Java. It can do file insert, file retrieve, node join and displaying the peer information. Node leave is not implemented. I mainly use Java RMI to implement all the functions of the CAN system, and use the socket to assist the routing mechanism.

File description

For implement the bootstrap: BootStrap.java Implement the interface that need to call remotely BootStrapInt.java The interface of the RMI function BootstrapServer.java Start the RMI service and bind the bootstrap object to network For implement the CAN system: CanNode.java All the remote function of the CAN system in this file CanNodeInt.java The interface of the CAN functions CanNodePeer.java Start RMI service and implement the join, view, insert and search InetArea.java The object for contain area of the node in the zone InetPoint.java The object for contain the coordinate and the IP address for find RoutingTable.java The object contain the surrounding peer IP and area information SysParameter.java The system parameter of the CAN system RunNetwork.java Main function for accept the required command

How to compile and run

All the files need to compile: javac *.java To start the bootstrap server: java BootstrapServer.java To start a peer: java RunNetwork.java

Set Bootstrap server IP

I assume the bootstrap server is running on: glados.cs.rit.edu. So make sure the bootstrap server is running on glados. If want to run the bootstrap server on other machine, open file SysParameter.java and change the variable: public static final String BOOT_IP = “glados.cs.rit.edu” to the IP address of the machine that you want running the bootstrap server.

Run the peer

The peers can run on the machine with different IP. It accept the command required by the project. To exit the program can use command “exit” or “quit”. To exit the bootstrap server press Ctrl + C on keyboard.
