The world is a jungle in general, and the networking game contributes many animals. -David C. Plummer ARP RFC
Contents
Overview
This assignment is part of the Networking With Xinu track for professors that are Teaching With Xinu and it is intended to be completed in groups of two or three.
Preparation
A new tar-ball is provided with a solution to the previous assignment. If your solution is similar to the one presented, you may choose to continue on with it; but it is suggested that you untar the new project files in a fresh working directory:
tar xvzf <tar-ball location>
Address Resolution Protocol
Standard 37 of the Internet Official Protocol Standards is the Address Resolution Protocol (ARP). In this assignment students will build the Address Resolution Protocol into Embedded Xinu.
Upon completion of the assignment the students' implementation should:
Required Assignment Parts
- add and remove ARP table entries
- send, receive and process ARP requests
- have ARP entries time out and be removed
- lookup MAC address from table (given an IP) and return it to help fill in packets before sending them
Optional Assignment Parts
- shell integration: add an 'arp' command to the shell
- options for: adding entry, removing entry, sending request, clearing table
Student Outcomes
Upon completion of this assignment students should understand the key role this protocol plays in the overall networking architecture. Each student should be able to understand what an Internet Protocol address is and how the protocol uses this address to acquire a MAC address for the network packet before it can proceed through the system and be sent out over the network.
