현재 위성 통신 시스템은 기존의 글로벌 서비스 인프라 구축이 가능하다는 장점에 고품질 통신 서비스 제공 기능을 더하여 명실 상부한 유비쿼터스 네트워크 환경을 지원하는 시스템으로 발돋움하기 위한 준비를 하고 있다. 이를 위해 기존의 DVB-RCS 대비 30% 이상의 성능 향상 지원을 목표로 하는 DVB-RCS NG 시스템에 대한 표준화 작업이 진행중에 있다. 이에 본 고에서는 DVB-RCS NG 표준화 동향과 더불어 DVB-RCS NG에서 표준화 채택이 유력한 링크계층 프로토콜로써 랜덤 액세스 기술과 인캡슐레이션 기술에 대해 전반적인 개념과 세부 기술을 살펴보고자 한다.
