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.
