이더넷(Ethernet)은 본래 캠퍼스, 기업이나 가정 등 근거리의 LAN 영역에 주로 사용되는 기술이었으나 플러그 앤 플레이(plug and play)와 같은 단순함(simplicity), 적은 설치 비용 및 쉬운 운용 등을 장점으로, 통신 사업자 및 운용자(carrier)의 고유영역인 MAN/WAN에서도 사용 가능한 메트로 이더넷 및 캐리어 이더넷(Metro/Carrier Ethernet)으로 빠른 속도로 진화 발전하고 있는 상황이다. 캐리어 이더넷은 탄력성(resiliency), 신뢰성(reliability), 확장성(scalability), 관리성(manageability) 등과 같은 특징을 중요시하는 통신 사업자 환경에서 이더넷 기반 서비스를 제공할 수 있는 확장된 이더넷 기술을 의미한다. 본 고에서는 캐리어 이더넷 기술에 대한 정의와 관련 서비스를 소개하고, MEF, IEEE 802, ITU-T, IETF 등 국제 기구 및 연관 포럼에서 진행중인 캐리어 이더넷 기술의 표준화 동향을 살펴보고자 한다.
