HP-UX SNAplus2 Release 7 family APPN (Advanced Peer-to-Peer Networking) End Node allows a single HP 9000 or Integrity system to connect simultaneously to both pre-APPN and APPN nodes.

HP-UX SNAplus2 Release 7 family APPN (Advanced Peer-to-Peer Networking) End Node allows a single HP 9000 or Integrity system to connect simultaneously to both pre-APPN and APPN nodes.

The SNAplus2 APPN End Node enables HP 9000 systems to operate at the periphery of an APPN network. Executing along with HP-UX SNAplus2 Link, the SNAplus2 APPN End Node product helps an HP 9000 system participate in APPN's dynamic configuration and resource location while simultaneously running other applications as well.

The HP-UX SNAplus2 Link provides the major features of an IBM 3274 cluster control unit and the lower four levels of systems network architecture (SNA). Physical Unit Type 2 (PU 2) and Type 2.1 (PU 2.1) Low Entry Node are emulated; Logical Unit Types 0, 1, 2, 3, and 6.2 (LU 0, LU 1, LU 2, LU 3, and LU 6.2) are supported.

Features

  • Supports APPN End Node capability while operating in traditional host-based networks
  • Enables sessions to span multiple communication links
  • Allows logical units (LUs) to be dynamically located as required
  • Supports dynamic definition of dependent LUs at the host
  • Supports the dependent LU requestor function, allowing sessions to be routed across an APPN network
  • Provides the APPN connection network feature reducing addressing complexity while increasing performance
  • Enables an HP 9000 system to be a node in an APPN environment. The nodes operate as peers instead of being controlled by a host computer.
  • Support for sessions can now span multiple communication links within the network, thus removing the restrictions of a single point-to-point connection.
  • Allows remote resource (LUs) to be dynamically located as required instead of being configured explicitly at the local system, easing network administration.
  • Information about other systems in the network is obtained dynamically, significantly reducing the require- ment for initial configuration.
  • Provides support for Dynamic Definition of Dependent LUs (DDDLU) at the host. While com- municating with a DDDLU-capable host, SNAplus2 APPN End Node can add required LUs to the host when the communication link to the host is established. The LUs need not be statically configured to the host. This simplifies both initial configuration and subsequent expansion.
  • Supports the Dependent LU Requestor (DLUR) function which works in conjunction with Dependent LU Server (DLUS) on the host. The combination of DLUR and DLUS provides the facility to route sessions for dependent LUs across an APPN network. Existing applications can be retained without modification while taking advantage of APPN's network management, dynamic resource location, and route selection capabilities.
  • Provides the APPN Connection Network feature in a Shared Access Transport Facility (SATF). In an SATF environment, APPN removes the requirement to define a Link Station between each pair of communicating nodes by defining a connection network, thus significantly reducing addressing complexity. In addition, a connection network reduces traffic on the LAN and improves performance.
