1.0  Introduction

The APPN Implementers' Workshop (AIW) is an industry-wide consortium
of networking vendors that develops Advanced Peer-to-Peer
Networking(R) (APPN(R)) standards and other standards related to
Systems Network Architecture (SNA), and facilitates high quality,
fully interoperable APPN and SNA internetworking products.  The AIW
approved Closed Pages (CP) status for the architecture in this
document on December 2, 1997, and, as a result, the architecture was
added to the AIW architecture of record.  A CP-level document is
sufficiently detailed that implementing products will be able to
interoperate; it contains a clear and complete specification of all
necessary changes to the architecture of record.  However, the AIW
has procedures by which the architecture may be modified, and the AIW
is open to suggestions from the internet community.

The architecture for APPN nodes is specified in "Systems Network
Architecture Advanced Peer-to-Peer Networking Architecture Reference"
[1].  A set of APPN enhancements for High Performance Routing (HPR)
is specified in "Systems Network Architecture Advanced Peer-to-Peer
Networking High Performance Routing Architecture Reference, Version
3.0" [2].  The formats associated with these architectures are
specified in "Systems Network Architecture Formats" [3].  This memo
assumes the reader is familiar with these specifications.

This memo defines a method with which HPR nodes can use IP networks
for communication, and the enhancements to APPN required by this
method.  This memo also describes an option set that allows the use
of the APPN connection network model to allow HPR nodes to use IP
networks for communication without having to predefine link
connections.
