Find a TCP-based protocol, read it, and understand it. Then you should write a text that explains the protocol, what it does, and a brief history of it (1 page). Then you should explain the protocol in detail, step by step (at least 2 pages). Include a flowchart. Finally, include a conclusion that explains why this protocol is set up the way it is and whether it might be improved. Choose a protocol that is neither too tiny nor too large.
