                            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 for the listed protocol.

RFC 758                                                      August 1979

Port or Socket Numbers



                    ASSIGNED PORT or SOCKET NUMBERS

   Ports are used in the TCP [46] and 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 unknown
   callers a service contact socket is defined.  This list specifies the
   port or socket used by the server process as its contact socket.  In
   the AHHP an Initial Connection Procedure ICP [1,34] is used between
   the user process and the server process to make the initial contact
   and establish the long term connections leaving the contact socket
   free to handle other callers.  In the TCP no ICP is necessary since a
   port may engage in many simultaneous connections.
