Map case network virtual connection interface system
First Claim
1. A system for establishing a communication connection for the transfer of information between a real MAP network of data processing computers and a real non-MAP connection-oriented network of data processing computers, wherein each of said data processing computers in each network is a type of electronic digital computing machine that can execute collections of user created instruction programs, and can be connected to a local area network, so that said programs can communicate with other programs in other data processing computers, said system comprising:
- each data processing computer in each of said networks being connected to execute predetermined user created data programs;
interface means to establish a Virtual MAP CASE connection path between a computer in said MAP network and a computer in said non-MAP connection-oriented network, in response to a request from either computer, in accordance with a State Table in FIG. 3 of the drawings;
said interface means being adapted to manage information transfer between said computers over said Virtual MAP CASE connection path in accordance with said State Table in FIG. 3 of the drawings;
so that said Virtual MAP CASE connection path presents the appearance of a real MAP connection path for the transfer of said information.

Abstract
The disclosure describes a system to permit communication between two dissimilar networks that involves an interface system. More particularly, it is an interface system to permit communication between a MAP network that is utilizing common application service elements (CASE) and a network of non-MAP computer equipment. The interface system that is described establishes a connection between the two networks which involves a process of decoding data from one network into predetermined component parts, and then encoding the component parts into data for transfer to computer equipment in the other network, and then, releasing the connection when the data transfer is completed, in accordance with the State Table of FIG. 3 of the drawings.
