OSI CLNS and LLC1 Protocols on Network Systems HYPERchannel
Status of this Memo
The intent of this document is to provide a complete discussion of
the protocols and techniques used to transmit OSI CLNS and LLC1
datagrams (and any associated higher level protocols) on Network
Systems Corporation's HYPERchannel equipment. This document is
intended for network planners and implementers who are already
familiar with the OSI protocol suite and the techniques used to carry
OSI traffic on standard networks such as 802.3.
This memo provides information for the Internet community. It does
not specify an Internet standard. Distribution of this memo is
unlimited.

Goals of this Document
In this document, we have three major technical objectives:
1. To standardize the encapsulation of LLC1 packets over
HYPERchannel. The format will be used for OSI CLNS and for
any other protocols using LLC1 over HYPERchannel. (Note
that if one desires to use the LLC1/SNAP combination for
TCP/IP, this is the format to use. This represents an
alternative to the native mode for TCP/IP over HYPERchannel,
allowing for sharing the medium at the LLC1 layer.)
