        Moving Outdated TCP Extensions and TCP-Related Documents
                  to Historic or Informational Status

Abstract

   This document reclassifies several TCP extensions and TCP-related
   documents that either have been superseded, have never seen
   widespread use, or are no longer recommended for use to "Historic"
   status.  The affected documents are RFCs 675, 721, 761, 813, 816,
   879, 896, 1078, and 6013.  Additionally, this document reclassifies
   RFCs 700, 794, 814, 817, 872, 889, 964, and 1071 to "Informational"
   status.

1.  Introduction

   TCP has a long history.  Over time, many RFCs have accumulated that
   describe aspects of the TCP protocol, implementation, and extensions.
   Some of these have been superseded, are no longer recommended for
   use, or have simply never seen widespread use.

   Sections 6 and 7.1 of the TCP roadmap document [RFC7414] already
   reclassified a number of TCP extensions as "Historic" and describes
   the reasons for doing so, but it did not instruct the RFC Editor to
   change the status of these RFCs in the RFC database.  The purpose of
   this document is to do just that.

   In addition, this document reclassifies all other documents mentioned
   in the TCP roadmap that currently have an "Unknown" status to either
   "Historic" or "Informational".

2.  Status Changes

   The following two sections give a short justification why a specific
   TCP extension or a TCP-related document is being reclassified as
   "Historic" or "Informational".  In addition, the letter code after an
   RFC number indicates from which original status a particular RFC is
   changed to "Historic" or "Informational" (see BCP 9 [RFC2026] for an
   explanation of these categories):

      S - Standards Track (Proposed Standard, Draft Standard, or
      Internet Standard)

      E - Experimental

      I - Informational

      H - Historic

      B - Best Current Practice

      U - Unknown (not formally defined)

   For the content of the documents itself, the reader is referred
   either to the corresponding RFC or, for a brief description, to the
