In this assignment you should find a TCP based protocol, read and learn how it works. The you should create a document which describes the protocol, what it does and a bit of its history (1 page). Then you should explain the protocol, step by step how it works (at least 2 pages). Add a sequence diagram. Finally, add a conclusion giving some insight about why this protocol is built like this and if there are any possibility of improvement. Do not pick a very small or very large protocol.
