미래지향적 네트워크 및 서비스 인프라의 구축을 위해 네트워크의 개방화와 가상화에 대한 관심이 높아졌다. 이를 지원하는 기술로서 SDN (Software-defined Networking) 및 NFV(Network Function Virtualisation) 기술이 소개되었다. 특히 트래픽에 따라 필요한 네트워크 기능들을 선택적으로 조합 및 실행하여 하나의 네트워크 서비스를 구현하는 서비스 체이닝(Service Chaining 혹은 Service Function Chaining) 기술이 높은 관심을 받고 있다. 이를 통해 컴포넌트 서비스들로 이루어진 경로를 정의함으로써 네트워크 서비스를 적시에 구성 및 능동적으로 제어할 수 있다. 본 고에서는 서비스 체이닝 기술의 기본 개념및 기능에 대해 간략히 소개하고, 주요 기능의 표준화를 담당하는 IETF SFC WG 의 주요 표준화 이슈에 대한 분석 및 향후 전망을 기술한다.
