KR950016082A - Prototype System and Control Method of Highly Intelligent Network Switching System - Google Patents

Abstract

The present invention relates to a prototype system and a control method of an advanced intelligent network switch, and the basic exchange function of the switched system can be easily implemented, and the functions of the advanced network switch and other network elements can be easily used by using a general library supported in a Unix environment. It is easy to implement the standardized structural concepts, modeling, and interfaces of the high-intelligence network by presenting the system structure of the high-intelligence network prototype as a basic exchange system that can be easily implemented with the general development environment of Unix and DOS. By using this, it is possible to verify whether the service can be provided quickly and easily through modularization and reuse of network functions, and since it is composed of general-purpose systems rather than specific systems, it is possible to flexibly apply the concept of evolving communication network to verify and understand quickly.It can be effective.
