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 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 provides HPR functionality over IP connections, to support SNA
applications connected over an IP network.
APPC Application Suite provides SNA equivalents of common TCP/IP applications such as
ftp and
ping, which use
independent LU 6.2 protocols to communicate with similar applications running on other nodes in the SNA network.
APPC Application Suite can be used to provide support for operations, such as file transfer, that are frequently
performed across a network.
SNAplus2 now supports Windows Client computers running the Windows 2000, Windows XP, or Windows Server
2003 operating systems.
