Nothing specifically assigned although you may want to review some of the RFCs in the documents folder so you can complete the assignment.  If you want to study protocols in a bit more detail, check out these references:

TCP/IP Illustrated: The Implementation
By W. Richard Stevens, Gary R. Wright
Contributor Gary R. Wright

600 pages
This is my personal favorite for getting started with network protocols.  It's an old text that hasn't been updated lately--which means you won't get confused with all the crazy workarounds that have been implemented over the years.  Start out with the fundamentals, then you can study RFCs that added the just features you're most interested in.
