OSI Transport for Windows

Our IMPART ISO Transport is one of the most popular OSI Transport Stacks in the world. Over 50,000 installations in the UK alone demonstrates its reliability, efficiency and robustness. Built from a common code base, the OSI transport is available under Windows NT, 98, 2000, XP and later systems. A UNIX version is also available.

For Windows, 98, 2000 and XP clients, the OSI Transport is written as a 32-bit VxD, whereas for Windows NT4, it’s a high-performance native transport driver supporting the Microsoft defined Transport Driver Interface (TDI) at the top and the Microsoft NDIS interface (for Ethernet LAN access) at the bottom.

Customer written applications can use the IMPART Application Data Interchange (ADI) interface which provides a simple set of functions for reading and writing data, and requires the IMPART addressing files, or the Winsock or WinXTI interfaces, for more precise control.

Key Features

IMPART OSI Transport operates over LAN and supports the following:

ISO 8073 Connection-Oriented Transport Protocol Class 4 over ISO 8802-3 LAN
ISO 8473 Connectionless Network Protocol (CLNP)
ISO 9542 End System to Intermediate System routing exchange protocol (ESIS)
Dynamic addressing for use when the full CLNP is not used. This is used for environments such as Fujitsu’s IPA3 OSLAN, where there is not a network protocol and therefore no ESIS
Support for multiple LAN LSAPs
Support for multiple LAN cards and sub-networks
Transport connection switching. This is used when communicating over null CLNP to systems that may switch the LAN sub-network address used by their transport connection e.g. Fujitsu’s multi-node VME
Extensive tracing, diagnostic and statistics facilities
A GUI interface for setting OSI Transport and network layer parameters
A choice of application programming interfaces
Limited support for Aeronautical Telecommunications Network Standards.
