인터넷 사용자들의 급증으로 인터넷을 이용한 다양한 부가서비스들이 창출되고 있으며 가장 대표적인 것이 인터넷 전화이다 최근들어 인스턴트 메시징 및 프레즌스 서비스의 응용서비스가 보편적으로 확대되고 있는 추세이며 이 서비스는 IETF의 IMPP 워킹 그룹에서 표준이 개발되고 있는데 IMPPP 워킹그룹에서는 인스턴트 메시징 및 프레즌스 서비스를 위한 기본 모델 및 요구사항, 공통데이터 포맷 등에 대한 표준을 담당하고 있다. 또한, 사용자의 친구 목록 관리 및 권한 부여 등 IMPP 서비스를 위한 확장은 SIMPLE 워킹그룹에서 정의하고 있다. 본 논문에서는 IETF SIMPLE(SIP for Instant Messaging and Presence Leveraging Extensions) 워킹그룸에 대한 표준 진행 사항과 IMPP 서비스에서 친구 목록 및 사용자의 권한 설정을 관리해주는 XCAP 서버 설계를 다룬다.
