Excerpt
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.
