A New Internet-Draft is available from the on-line Internet-Drafts 
directories.

Modern implementations of TCP contain four intertwined algorithms that have
never been fully documented as Internet standards:  slow start, congestion 
avoidance, fast retransmit, and fast recovery.  [2] and [3] provide some 
details on these algorithms, [4] provides examples of the algorithms in 
action, and [5] provides the source code for the 4.4BSD implementation.  
RFC 1122 requires that a TCP must implement slow start and congestion 
avoidance (Section 4.2.2.15 of [1]), citing [2] as the reference, but fast 
retransmit and fast recovery were implemented after RFC 1122.  The purpose 
of this Internet Draft is to document these four algorithms for the 
Internet.                                                                  

Internet-Drafts are available by anonymous FTP.  Login with the username

Send a message to:  [e-mail]. In the body type: 
     "FILE /internet-drafts/draft-stevens-tcpca-spec-00.txt".
							
NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.
							
For questions, please mail to [e-mail].
							

Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
of the Internet-Draft.
