Abstract

본 발명은 기존 LAN을 ATM 망에 접속시켜 LAN 간에 ATM 교환기능을 제공할 수 있도록 하는 교환장치에 관한 것이다.The present invention relates to an exchange apparatus capable of providing an ATM exchange function between LANs by connecting an existing LAN to an ATM network.

본 발명은 임의의 포트로부터 입력된 ATM셀을 적절한 방법에 의해 원하는 포트로 출력하는 ATM교환모듈(1), 다수의 기준 LAN들을 집선하여 ATM교환모듈에 접속하는 LAN가입자 접속모듈(3), ATM단말이나 ATM교환기 등을 ATM교환모듈에 접속시키는 ATM가입자 접속모듈(2), 각 가입자 접속모듈의 제어, ATM-LAN구축을 위해 요구되는 프로토콜, 연결 설정/해제제어를 위한 신호 프로토콜 및 ATM교환모듈 제어기능등을 수행하는 실시간 처리모듈(4,5)를 구비하며, ATM 교환모듈을 이용하여 본 발명과 연결된 단말이나 교환기간의 멀티캐스팅을 지원하며 LAN간 연결에 사용되는 라우터(Router)의 고장시에도 교환기능을 통해 LAN간의 연결을 제공하므로써 망의 신뢰성(Reliability)를 극대화시킬 수 있다. 또한 고유의 ATM-LAN이 전개되어가는 과정에서 허브(Hub)로서 사용될 수 있으므로 별도의 장치없이 기존 LAN 및 ATM단말을 접속시켜 손쉽게 망을 구축할 수 있는 효과가 있다.The present invention provides an ATM switching module (1) for outputting an ATM cell inputted from an arbitrary port to a desired port by an appropriate method, a LAN subscriber connection module (3) for converging a plurality of reference LANs and connecting the ATM switching module, and ATM. ATM subscriber access module (2) for connecting terminals or ATM exchangers to ATM exchange modules, control of each subscriber access module, protocols required for ATM-LAN establishment, signaling protocols for connection establishment / release control, and ATM exchange modules It is provided with a real-time processing module (4, 5) performing a control function, etc., using the ATM exchange module to support the multicasting of the terminal or exchange period connected to the present invention, the failure of the router (Router) used for connection between LANs It also maximizes the reliability of the network by providing connectivity between LANs through the exchange function. In addition, since a unique ATM-LAN can be used as a hub in the process of deployment, it is possible to easily establish a network by connecting existing LAN and ATM terminals without a separate device.
