           A Roadmap for Transmission Control Protocol (TCP)
                        Specification Documents

Abstract

   This document contains a roadmap to the Request for Comments (RFC)
   documents relating to the Internet's Transmission Control Protocol
   (TCP).  This roadmap provides a brief summary of the documents
   defining TCP and various TCP extensions that have accumulated in the
   RFC series.  This serves as a guide and quick reference for both TCP
   implementers and other parties who desire information contained in
   the TCP-related RFCs.

   This document obsoletes RFC 4614.
