APPN Networking

SNAP-IX supports both traditional hierarchical SNA and more modern APPN networks, thus allowing users to benefit from the ease of configuration, fault tolerance and modern link types that are provided by APPN. A single SNAP-IX system can connect simultaneously to both pre-APPN and APPN nodes.

SNAP-IX can operate as a Network Node, End Node, or LEN Node, depending on its configuration. It takes full advantage of APPN facilities, including dynamic configuration and resource location, while still retaining the capability to operate in traditional host-managed SNA networks.

• Resources can be added, deleted, or modified as required while the system is running, without having to stop and restart the system.
• The APPN Node provides inherently dynamic configuration as it learns about other resources in the network, reducing the amount of information to be configured at each system.
