About

This is a very light implementation of Routing Information Protocol (Networking) using POSIX Threads.

The idea is to have some n number of files in the directory names ($n.txt). These files represent routers. In each file there are three space separated columns.

Col-1 Col-2 Col-3

• Col-1: This is the name of the router file.

• Col-2: This is the distance between the router whose name is specified in col-1 and with the router whose file you have currently opened. If this distance is: "1" : directly connected "2" : connected at a distance of 2 metres. (1 metre for directly connected) ... "16": not reachable, infinite distance.

  Hence, the maximum distance reachable is 15

• Col-3: This specifies the next hop destination to reach the router whose name is specifies in Col-1. A hop of 0 , means no hop is required. Initially, there are obviously no hops

What all can I do

• Add a router. You don't create a new file. The new router remains in memory. The initial router files are just for initiation since I needed File Handling as the initialisation approach.
• Fail a link:
• Add a link:
• Invalidate a router
• Revalidate a router
• Exit simulation:

All of these actions have been carefully studies and implemented. I would appreciate if someone could come up with their bugs or an efficient code perhaps.
