IEEE 802 Numbers


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 MILNET uses the "link" field.  Further, there is an
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.
The address is:

IEEE Registration Authority
c/o Iris Ringel
IEEE Standards Dept
445 Hoes Lane, P.O. Box 1331
Piscataway, NJ 08855-1331
Phone +1 908 562 3813
Fax: +1 908 562 1571

The fee is $1000 and it takes 10 working days after receipt of the
request form and fee.  They will not do anything via fax or phone.

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 send DoD-IP datagrams and other IP related protocols
(such as the Address Resolution Protocol (ARP)) on 802 networks was
developed, using the SNAP extension (see [RFC1042]).
