before Wanware SNA -Illustration

Wanware SNA is a comprehensive, state-of-the-art connectivity solution for PC-based local area networks and standalone workstations. Available in client/server and traditional (host-based) versions, Wanware SNA emulates a full range of IBM devices and communications protocols, giving users a high-speed interface to SNA network applications and resources.

Wanware SNA emulates 3270, 5250, and RJE terminal and printer devices, allowing any number of users to access SNA hosts or peers through a local UNIX server. Wanware SNA can be installed either as a "standalone" application on a single PC, or as a client/server application on a LAN server. Each client can be configured to run multiple sessions, permitting users to access multiple hosts or run multiple applications.

after Wanware SNA -Illustration

To physically connect to the SNA network, Wanware SNA includes a high-speed WAN adapter that installs in the LAN server - the same robust, time-proven technology used in Netcom and NetcomHighway products. Using SDLC, QLLC/X.25, or LLC2 physical links, Wanware SNA supports both peer (APPN) and point-to-point (PU 2.0/PU 2.1) communications sessions.

APPN offers significant advantages over traditional SNA implementations. For example, Logical Units (LUs) can be "pooled" and allocated on an as-needed basis, ensuring more optimal use of network resources. In APPN peer environments, each session can span multiple communications links within the network, negating the restriction imposed by traditional point-to-point connections.

For administrators, APPN permits SNA node configuration tables to be updated dynamically (either locally or by the network), without rebooting the system. In the event of a link failure, APPN allows a server to automatically activate a second (back-up) link, without the need for manual intervention.

Since Wanware SNA was developed specifically for high-performance, multi-threaded UNIX server engines, your technology investment is not subject to the costly changes and limitations inherent in proprietary products. Wanware SNA is a modular, easy-to-install solution that enables you to simply "plug in" component upgrades as hardware and software technology evolves. Call today to find out more!

Network Management Tools

Wanware SNA is NetView-aware and includes Service Point Command Facility (SPCF) and Network Operator Facility (NOF) support. Extensive software utilities assist with system configuration, monitoring and logging, alarms, run-time management, problem determination, and command-line scripting for common operations.

An X.3, X.28 and X.29 PAD is supported by Wanware SNA. PAD connects remote terminals without requiring asynchronous hardware and modems. Users can connect to any X.25 host on the network.

Protocol Support

Wanware SNA runs over X.25, SDLC and QLLC.

Additional Functionality

Wanware SNA also offers an industry-standard 'C' library of programmatic interfaces for developing EHLLAPI, CPI-C, APPC/LU6.2, LUA, and CSV applications. Wanware SNA is ISO 8859 compliant, observing portability definitions for national language support (NLS), international character sets, keyboard mapping, and localization of Motif user interface functions.
