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 networksShow full document text
