NWG/RFC# 739 JBP 11 Nov 77 42341 Assigned Numbers

Network Working Group J. Postel Request for Comments: 739 USC-ISI NIC: 42341 11 November 1977

                          ASSIGNED NUMBERS

This Network Working Group Request for Comments documents the currently assigned values from several series of numbers used in network protocol implementations. This RFC will be updated periodically, and in any case current information can be obtained from Jon Postel. The assignment of numbers is also handled by Jon. If you are developing a protocol or application that will require the use of a link, socket, etc. please contact Jon to receive a number assignment.

Most of the protocols mentioned here are documented in the RFC series of notes. The more prominent and more generally used are documented in the Protocol Handbook [1] prepared by the Network Information Center (NIC). In the lists that follow a bracketed number, e.g. [1], off to the right of the page indicates a reference to the protocol assigned that number.

                                                              [Page 1]

NWG/RFC# 739 JBP 11 Nov 77 42341 Assigned Numbers Assigned Link Numbers

                       ASSIGNED LINK NUMBERS
 The word "link" here refers to a field in the original ARPANET
 Host/IMP interface leader.  The link was originally defined as an 8
 bit field.  Some time after the ARPANET Host-to-Host (AHHP) protocol
 was defined and, by now, some time ago the definition of this field
 was changed to "Message-ID" and the length to 12 bits. The name link
 now refers to the high order 8 bits of this 12 bit message-id field.
 The low order 4 bits of the message-id field are to be zero unless
 specifically specified otherwise for the particular protocol used on
 that link.  The Host/IMP interface is defined in BBN report 1822 [2].

NWG/RFC# 739 JBP 11 Nov 77 42341 Assigned Numbers Assigned Socket Numbers

                      ASSIGNED SOCKET NUMBERS
 Sockets are used in the AHHP [1,3] to name the ends of logical
 connections which carry long term conversations.  For the purpose of
 providing services to all callers an Initial Connection Procedure ICP
 [1,34] is used between the user process and the server process.  This
 list specifies the socket used by the server process as its contact
 socket.
