Computer networking - practical exercises using the mininet emulator

Exercises

We currently have four non-trivial Java programming exercises, designed to reinforce the principles presented in the Computer Networking course.

Reliable transport
This practical requires you to implement a reliable, sliding window transport protocol for transmitting data over a potentially lossy channel.
Simple router
The objective of this exercise is to build a router that will forward packets between network segments based upon rules in the static routing table that you give it.
Dynamic routing (PWOSPF)
After you have completed this exercise, you will no longer have to feed your router a static routing table, since it will be able to figure out routes itself.
Net address translation (NAT)

The final two exercises build upon your simple router code, so you must complete that exercise before moving on. Additional exercises are currently under development.

Infrastructure and library code

Java library functions (mahameru)

Downloads:

A .jar file and raw socket library can be downloaded here (plug-and-play).
Source code (mahameru is still in the pre-alpha stage, so this may be useful for debugging if something doesn't work).
API documentation.

Test topologies (CaMT)
