New and Changed Information in This Edition
SNAplus2 can now operate as an APPN Network Node, which resides in the backbone of an APPN network and
provides resource location and session routing facilities. Alternatively, it can still operate as an End Node or LEN
Node (as in earlier versions).
SNAplus2 can also operate as a Branch Network Node, allowing the APPN network to be separated into branches
to simplify its topology and reduce network management overheads. A Branch Network Node provides network
node functions to end nodes in a branch separated from the main APPN network, while acting as an end node in
the main network itself.
The High-Performance Routing (HPR) feature of APPN is now included. This provides Rapid Transport Protocol
(RTP), minimizing cycles and storage requirements for routing network layer packets through intermediate nodes on
a session route, and Automatic Network Routing (ANR), enabling APPN networks to automatically reroute sessions
if a portion of the originally computed route fails.
Enterprise Extender (HPR/IP) connectivity is now included. This provides HPR functionality over IP connections,
to support SNA applications connected over an IP network.
