   * stability and fairness of the internet relies on the use of congestion control mechanisms
      * %BLUE%refers to the congestion collapse in the 80s
      * %BLUE% _bandwidth_ - describes the maximum data transfer amount over a certain time 
   * [TBIT can] detect bugs and non-compliance in TCP implementations deployed in public web servers

---++__%NAVY%Introduction%ENDCOLOR%__
   * Understanding TCP behavior can be important for Internet-related research, ISPs, OS Vendors and application developers.
   * [web servers were chosen to test TCP behavior because] web servers will respond to a request for information without requiring any special privileges
   * TBIT shows that newer TCP variants such as NewReno and SACK are widely deployed in the Internet
   * TCP initial window used at a web server can not necessarily be inferred simply by knowing the operating system used at that server
   * useful not only in simulations and modeling, but also in standards-body decisions to advance documents specifying larger values for initial windows
   * ability to publically identify end hosts not conforming to end-to-end congestion control can help significantly in reinforcing the use of end-to-end congestion control in the Internet
   * TBIT...identifies these failure modes and the extent of their deployment in the Internet, to identify the responsible vendors, and to track the progress (or lack of progress)
   * TCP behavior determined by equipment on the path to the server
   * [tests of ECN are] testing for the presence of firewalls and load balancers that block access to servers from hosts attempting to negotiate ECN
   * interested in understanding the congestion control behavior in the Internet and not just the congestion control of the web server boxes
