Introduction

   Discussion of the standardization process and the RFC document series
   is presented first, followed by an explanation of the terms.
   Sections 6.2 - 6.9 contain the lists of protocols in each stage of
   standardization.  Finally come pointers to references and contacts
   for further information.

   This memo is intended to be issued quarterly; please be sure the copy
   you are reading is current.  Current copies may be obtained from the
   Network Information Center or from the Internet Assigned Numbers
   Authority (see the contact information at the end of this memo).  Do
   not use this edition after 30-Nov-91.

   See Section 6.1 for a description of recent changes.  In the official
   lists in sections 6.2 - 6.9, an asterisk (*) next to a protocol
   denotes that it is new to this document or has been moved from one
   protocol level to another.
