                       ASSIGNED PROTOCOL NUMBERS

   In the Internet Protocol (IP) [46,101] there is a field, called
   Protocol, to identify the the next level protocol.  This is an 8 bit
   field.

                         ASSIGNED PORT NUMBERS

   Ports are used in the TCP [46,102] to name the ends of logical
   connections which carry long term conversations.  For the purpose of
   providing services to unknown callers, a service contact port is
   defined.  This list specifies the port used by the server process as
   its contact port.  The contact port is sometimes called the
   "well-known port".

   To the extent possible, these same port assignments are used with the
   UDP [46,100].

   To the extent possible, these same port assignments are used with the
   ISO-TP4 [64].

   The assigned ports use a small portion of the possible port numbers.
   The assigned ports have all except the low order eight bits cleared
   to zero.  The low order eight bits are specified here.

   Port Assignments:

                   ASSIGNED AUTONOMOUS SYSTEM NUMBERS

   The Exterior Gateway Protocol (EGP) [115,118] specifies that groups
   of gateways may form autonomous systems.  The EGP provides a 16-bit
   field for identifying such systems.  The values of this field are
   registered here.

                        DOMAIN SYSTEM PARAMETERS

   The Internet Domain Naming System (DOMAIN) includes several
   parameters.  These are documented in RFC 883 [80].  The CLASS
   parameter is listed here.  The per CLASS parameters are defined in
   separate RFCs as indicated.

                   ASSIGNED ARPANET LOGICAL ADDRESSES

   The ARPANET facility for "logical addressing" is described in
   RFC 878 [74].  A portion of the possible logical addresses are
   reserved for standard uses.

   There are 49,152 possible logical host addresses.  Of these, 256 are
   reserved for assignment to well-known functions.  Assignments for
   well-known functions are made by Joyce Reynolds.  Assignments for
   other logical host addresses are made by the NIC.

   Logical Address Assignments:

                     ASSIGNED ARPANET 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.  Later specifications defined this field as the
   "message-id" with a length of 12 bits.  The name link now refers to
   the high order 8 bits of this 12-bit message-id field.  The Host/IMP
   interface is defined in BBN Report 1822 [10].

   The low-order 4 bits of the message-id field are called the sub-link.
   Unless explicitly specified otherwise for a particular protocol,
   there is no sender to receiver significance to the sub-link.  The
   sender may use the sub-link in any way he chooses (it is returned in
   the RFNM by the destination IMP), the receiver should ignore the
   sub-link.

                      IEEE 802 NUMBERS OF INTEREST

   Some of the networks of all classes are IEEE 802 Networks.  These
   systems may use a Link Service Access Point (LSAP) field in much the
   same way the ARPANET uses the "link" field, further, there is a
   extension of the LSAP header called the Sub-Network Access Protocol
   (SNAP).

   The IEEE likes to describe numbers in binary in bit transmission
   order, which is the opposite of the big-endian order used throughout
   the Internet protocol documentation.

   These numbers (and others) are assigned by the IEEE Standards Office.

   At an ad hoc special session on "IEEE 802 Networks and ARP" held
   during the TCP Vendors Workshop (August 1986), an approach to a
   consistent way to sent DOD-IP datagrams and other IP related
   protocols on 802 networks was developed.

   Due to some evolution of the IEEE 802.2 standards and the need to
   provide for a standard way to do additional DOD-IP related protocols
   (such as Address Resolution Protocol (ARP)) on IEEE 802 networks, the
   following new policy is established, which will replace the old
   policy (see RFC-960 and RFC-948 [138]).

   The new policy is for DDN and ARPA-Internet community to use IEEE
   802.2 encapsulation on 802.3, 802.4, and 802.5 networks by using the

Top       Page 37 
   SNAP with an organization code indicating that the following 16 bits
   specify the Ethertype code (where IP = 2048 (0800 hex), see Ethernet
   Numbers of Interest).

                                                                  Header

      ...--------+--------+--------+
       MAC Header|      Length     |                     802.{3/4/5} MAC
      ...--------+--------+--------+

      +--------+--------+--------+
      | Dsap=K1| Ssap=K1| control|                             802.2 SAP
      +--------+--------+--------+

      +--------+--------+---------+--------+--------+
      |protocol id or org code =K2|    Ether Type   |         802.2 SNAP
      +--------+--------+---------+--------+--------+

   The values of K1 and K2 must be assigned by the IEEE.  There is
   already assigned a value of K1 that indicates that the 5-octet SNAP
   header follows.  There may be a value of K2 that is already assigned
   that indicates that the last two octets of the SNAP header holds the
   EtherType.

   The total length of the SAP Header and the SNAP header is 8-octets,
   making the 802.2 protocol overhead come out on a nice octet boundary.

   K1 is 170.  The IEEE like to talk about things in bit transmission
   order and specifies this value as 01010101.  In big-endian order, as
   used in Internet specifications, this becomes 10101010 binary, or
   AA hex, or 170 decimal.

   We believe that K2 is 0 (zero).  This must be further investigated.
   As an interim measure use K2 = 0.

   The use of the IP LSAP (K1 = 6) is to be phased out as quickly as
   possible.

   Many of the networks of all classes are Ethernets (10Mb) or
   Experimental Ethernets (3Mb).  These systems use a message "type"
   field in much the same way the ARPANET uses the "link" field.
