IEEE 802 Numbers

IEEE 802 Numbers


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

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.

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]).
