COSC364 RIP Assignment

Simulates RIP routing protocol.

Reads id, port, and output data from .config files with multiple example networks provided.

Completed to satisfaction for submission only just in the final moments with a significant bug fix and half an hour remaining to write a report - it was a very hectic and chaotic semester.

Authors:

Instructions

Requirements

  • Python3

Run

Single RIP router .config file

python3 rip_node.py <single .config file>

Network of multiple RIP router .config files

python3 rip_network.py <directory containing .config files>

Example

RIP routing simulation for router #1 when using a four-node network with router #3 inactived:

Welcome to the RIP router program. Awaiting initialization...
Router #1 has initialized successfully

----ROUTER #1 INITIALIZATION CONFIRMATION----
Router #1 ports: [1774, 1040, 1041]
Router #1 sockets and bounded ports: 
(2, <socket.socket fd=5, family=2, type=2, proto=0, laddr=('127.0.0.1', 1774)>)
(3, <socket.socket fd=6, family=2, type=2, proto=0, laddr=('127.0.0.1', 1040)>)
(4, <socket.socket fd=7, family=2, type=2, proto=0, laddr=('127.0.0.1', 1041)>)
