Very good reading. I'd also recommend Van Jacobson's talk https://www.youtube.com/watch?v=gqGEMQveoqg You'll learn some good stories about internet history.

He has done a lot of work on TCP congestion control, especially the fast retransmission idea by using duplicate ACKs.

There is an interesting thing about TCP. A lot of popular TCP implementation use city names, e.g. TCP Reno, TCP Vegas, TCP Westwood.

TCP Westwood is a very interesting implementation. It has very intelligent way to estimate bandwidth, (not just based on duplicate ACKs). You may find this paper very interesting. http://netlab.cs.ucla.edu/internal/wiki-internal/files/rohit...
