*
* \brief An implementation of a stream socket using TCP.
*
* This class contains the Tahoe implementation of TCP. Tahoe is not officially
* published in RFC. The reference for implementing this is based on
* Kevin Fall and Sally Floyd, "Simulation-based Comparisons of Tahoe, Reno, and SACK TCP", CCR, 1996
* http://inst.eecs.berkeley.edu/~ee122/fa05/projects/Project2/proj2_spec_files/sacks.pdf
* In summary, we have slow start, congestion avoidance, and fast retransmit.
* The implementation of these algorithms are based on W. R. Stevens's book and
* also RFC2001.
