Abstract
This invention provides a system for transparently mapping user level non-asynchronous transfer mode (ATM) sockets to an ATM virtual channel circuit associated with an operating system of a computer workstation and includes an ATM middleware subsystem for receiving a plurality of ATM extension calls from a non-ATM aware application and translating the plurality of ATM extension calls to a plurality of native ATM API calls. A configuration data base stores translation data for translating the ATM extension calls from the non-ATM application to the native ATM API calls. A WinSocket.TM. application receives the native ATM API calls from the ATM middleware subsystem and responsively generates signals for controlling the operating system according to the contents of the native ATM API calls. The ATM middleware system further generates formatted calls to the operating system from the plurality of ATM extension calls according to preexisting protocols associated with the operating system.
