Abstract

등시성 이더넷, 이더넷, 등시성 토큰링, 토큰링, 다른 등시성 LAN 또는 다른 LAN 시스템과 같은 다수의 등시성 및 비-등시성 LAN 프로토콜을 포함할 수 있는 혼합된 네트워크 환경의 지원이 제공된다. 혼합된 환경의 지원에는 핸드쉐이킹 방법으로 구현되는 프로토콜 검출 메카니즘이 있다. 상기 핸드쉐이킹 방법은 링크 종단의 시그널링 자격을 판단하여 정확한 프로토콜을 실행한다. 이렇게 함으로서 등시성 노드와 허브는 이더넷, 토큰링 또는 네트워크 케이블의 다른 단에 있는 다른 LAN장치의 존재를 자동적으로 검출한다. 만약 이와같은 검출이 발생한다면, 상기 등시성 LAN 장치는 LAN에 호환하는 동작 모드로 폴백(fall-back)할 것이다. 전형적으로, 단지 상기 허브만이 이더넷, 토큰링 등시성 모드와 같은 다른 네트워킹 모드로 동작할 수 있는 자격을 가질 것이다. 상기 허브는-등시성 또는 비등시성; 이더넷, 토큰링 또는 다른 LAN 서비스를 제공하는 서비스의 종류에 대해 부속된 노드와의 식별형태를 경청할 것이다.
