Here are some specific questions that I am pondering as I get 
ready to write the final exam. I will be happy to discuss potential 
solutions via email. Do not send me mail saying "Hey, what's the 
answer to number 7?"  Instead, send me your proposed solution.


1) What features does UDP provide? What is the header format?

2) What features does TCP provide? What is the header format?

3) What are the types of errors that we handle in ARQ protocols
   and how do we handle them?

4) Calculate utilization and window size requirements for sliding window 
   protocols under varying conditions (e.g. frame size and propogation delay) 

5) For TCP, explain how the retransmit timer works and how it is calculated?

6) Explain how the retransmit timer works and how it is calculated?

7) What is the difference between Flow Control and Congestion control?

8) How is Flow Control performed in TCP? UDP?

9) How is Congestion Control performed in TCP? UDP? What are the
   drawbacks to this approach?

10) You should know how to read and follow the TCP connection state diagram.
   You do not have to memorize every detail but should be able to answer 
   questions about it.
