Internet Protocol
Two parts of standard number 5 of the Internet Official Protocol Standards are the Internet Protocol (IP) and the Internet Control Message Protocol (ICMP). In this assignment students will build both IP and ICMP into Embedded Xinu.
Upon completion of the assignment the students' implementation should:
Required Assignment Parts
- send and receive packets of with type IP
- further demultiplex IP packets to find the underlying type
- send and receive ICMP packets
Optional Assignment Parts
- reply to ICMP echo requests properly
- shell integration: add a 'ping' command to the shell (sending out echo requests)
Student Outcomes
Upon completion of this assignment students should understand the key role this protocol plays in the overall networking architecture. Each student should also be able to understand the unique ties between the Internet Protocol and the Internet Control Message Protocol.
