광교환 및 광라우팅 기술은 광인터넷에 접속되는 이용자가 원하는 인터넷 서비스를 실시간으로 제공받을 수 있도록 대상 목적지를 찾아 최단 시간내에 접속시켜 주기 위해 광인터넷 제어평면을 이용한다 GMPLS기반 광인터넷 제어평면은 노드간 신호 유형 및 신호속도, 그리고 전송 프레임 구조 등과 무관한 호/연결 접속 능력을 제공하기 위해 기존의 계층 2.5 스위칭 구조인 MPLS개념에 계층 1스위칭 구조로까지 확장된 개념이다. 이 확장된 개념을 기능 구조화하고 시스템화하기 위해서는 표준화 상황 및 기술개발 동향을 분석하고, 노드간 상호연동성을 보장할 수 있는 현실적인 시나리오와 기능 구조를 우선 결정해야한다. 본 논문에서는 시스템 엔지니어링 관점에서 광인터넷 제어평면의 개념 단계에서부터 시스템 단계에 이르기까지 표준화 상황, 제어평면 기능, 그리고 시스템 적용 등을 단계적으로 기술함으로서, 제어평면 관련 광인터넷 시스템에 좀더 가까이 다가서고자 한다.
