최초의 이더넷 IEEE 표준인 48비트 주소체계와 버스 토폴로지를 갖는 10Mbps 이더넷이 1985년에 승인받은 이후, 이더넷 기술은 1995년 100Mbps 이더넷, 1998년 1 Gbps 이더넷, 2002년 10G 이더넷 표준 등장으로, 전송 용량을 10배씩 높이는 기술 발전이 표준으로 완성까지 시간이 오히려 짧아질 정도로 숨가쁘게 진화를 거듭하였다. 이더넷 전송 용량의 급속한 증가는 LAN과 WAN간 액세스 속도 차이를 급속하게 줄이는 결과를 가져와, 그렇지 않아도 대역폭 제한과 유연성 결여로 문제가 되던 전통적인 last mile WAN 서비스를 대체하는 것을 시작으로 결국에는 pure Ethernet WAN transport 기술로 캐리어 이더넷이라는 새로운 이더넷 적용 분야가 등장하게 되었다. 이 글에서는 캐리어 이더넷 네트워크 서비스의 출현 과정과 서비스 특징을 소개하며, 캐리어 이더넷 네트워크 구조 관련 요소 기술로 이더넷의 백본 확장 기술, OAM, resilience, QoS 기술 동향을 정리하고, 마지막으로 캐리어 이더넷 개발 현황과 향후 발전 전망에 대하여 살펴본다.
