Network Access


OSI-TCP

These products are implementations of the ISO Transport Protocol Class 0 on top of TCP according to RFC-1006. They allow the OSI upper layers to run over TCP-IP based networks.

OSI-TCP is a driver level implementation whereas OSI-TMUX is a user-space implementation. Either products provides a Winsock interface for applications based on FTAM and CMIP to run seamlessly over TCP-IP networks. 

OSI-TMUX stands for Transport Stack Multiplexor. It enables communication with any of the three Transport stacks namely OSI-LAN, OSI-WAN and Microsoft TCP-IP at the same time.

An ISV can easily integrate their Upper Layers using this API and provide LAN, WAN and TCP-IP connectivity to OSI applications simultaneously.

The products have been tested for suitability with Telecommunications environment. It has undergone extensive reliability, performance, and stress testing with Hewlett-Packard HP-OV product for TMN.

Conformance 

OSI-TCP / OSI-TMUX have been implemented in conformance with RFC-1006 standard.

Interoperability 

I
nteroperability tests with a variety of systems were carried out as part of the quality assurance process. It interoperates with Sun/Solaris as well as HP/HP-UX implementations of RFC-1006.

Socket Primitives Supported 

The OSI-TCP provides a standard Winsock interface. 

The OSI-TMUX provides a Winsock-like interface. Each function call is prefixed with TMUX. This is because it is not a driver level component, but a user-space component.

Standards 

OSI-TCP and OSI-TMUX supports the following protocols: 

  • RFC-1006 

OSI Application developer 

  • Programming Guide: Interface description for Winsock functions. 

  • Sample application in 'C' demonstrating the use of OSI-TCP as well as OSI-TMUX services. 

System Requirements 

Hardware - Intel PC with suitable LAN communication board
Software - MS-Windows NT V3.1/3.5/3.51/4.0/Windows-2000

Complementary Products

OSI-CMIP - CMIP/ROSE protocols. Includes an ASN.1 compiler OSI-MAPS - ACSE/PRES/SESS Layers. Offers XAP API
