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.
