Assignment 1 Breakdown - Spring 2025

Welcome, everyone! This page is your starting point for Assignment 1: Simulating Data Forwarding Operations of Network Routers. In this assignment, you'll use the C programming language to simulate the core functions of network routers, including reading routing data, generating packets, and simulating packet forwarding.

Assignment Overview

In this assignment, you will:

• Read and process data from files:

  • nodeinfo.txt: Contains node names and IP addresses.

  • linkinfo.txt: Describes the connections between nodes, including link cost and bandwidth.

  • routeinfo.txt: Provides pre-computed routing information (source, destination, next hop, and cost).

  Create a routing table:

  • Use the data from the files to build a routing table where each node has an entry for every destination. Each entry includes the destination node, the cost to reach it, and the next hop on the path.
