TPS®/SNA Product Series

Published in TPS

TPS®/ SNA ( Systems Network Architecture ) is a full featured SNA implementation for both traditional hierarchical subarea networks ( PU 4 / 5 to PU 2.0 ) and peer-to-peer networks ( PU 2.1 ). LU support includes dependent support for LUs 0, 1, 2, 3, 4, 7 and dependent and independent LU support for LU 6.2. TPS®/ SNA supports multiple links ( PUs ) and data link types on the same system ( limited only by the number and type of hardware adapters on the system ). Data link types supported include: SDLC, Token Ring, Ethernet, or Data Link Switching - DLSw ( Switch-to-Switch Protocol ).

TPS® /SNA provides a full set of standard SNA APIs, including CPI-C ( Common Programming Interface - Communications ), APPC ( Advanced Program to Program Communications ) and dependant LU API for LU types 0, 1, 2, 3, 4, and 7. Developers can then write user application programs to interface directly with host applications. TPS®/ SNA can also be used with TPS® /SNA Primary to create a ‘Virtual SNA Mainframe’ so you can migrate your host applications to the UNIX® platforms.

TPS®/SNA works with TPS®/ 3270 ( SNA ) emulation, TPS®/ RJE ( Remote Job Entry ), and many other networking software applications to provide exceptional client to host connectivity. TPS®/ SNA can also be used with TPS®/ TN3270 Server to create an Internet TN3270 gateway environment.

TPS®/ SNA is not only exceptionally reliable, but it makes host connectivity economical and easy.


TPS®/ SNA can be used with TPS®/ SNA Primary to simulate a ‘Virtual SNA Mainframe’. Ideal for company looking to replace their mainframe or write customized applications. With TPS®/ SNA API support, TPS®/ SNA is an excellent fit for developing SNA applications.

ARCHITECTURE

TPS®/SNA uses standard UNIX® functions to support the data link and application interfaces. This makes TPS®/SNA portable across UNIX® platforms and gives a common look and feel if TPS®/SNA is run on differing UNIX® platforms. It also makes the product very independent of UNIX version changes. When an upgrade is made to the operating system, a new version of SNA is not required.

TPS®/SNA was designed with performance in mind. Advanced message buffering and handling techniques have been used for the SNA traffic to reduce the processor and memory overhead.

PRODUCT POSITIONING

TPS®/ SNA is an ideal solution for SNA connectivity in distributed UNIX® networks. In addition to being full-featured, ultra-reliable and delivering maximum performance with minimum system overhead, TPS®/ SNA is very competitively priced.
