TCP congestion control
Suppose you are using TCP to transfer a 4 MB file over a network. The receiver advertises a receive window of 4 MB. Assume that the retransmission timers expire after 5 RTTs. (a) If TCP sends 4KB segments, how many RTTs does it take ... implements fast retransmit and fast recovery. How many RTTs are saved by the fact that your TCP implements fast retransmit and fast recovery?

TCP - Stanford Lectures
In one of the quizes, they asked the following question : "A server typically listens for TCP connections on a particular port (e.g. 80 for HTTP or 22 for SSH). Which fields can the server use to distinguish packets for a particular ... address from the packet received from the client... (After all, this destination IP address corresponds to the Server itself !).
