XMPP/Jabber 란 ?
• eXtensible Message & Presence Pro-tocol– “XML 스트리밍 기술로 인터넷상의 두 지점간
Presence, Message 그리고 XML 로 표현가능한 구조적 정보를 실시간으로 전달하기 위한 국제 표준 .
XML

XMPP History1998 1999- 2000 2002-2003 2004 2005 2009
•독점적인 IM 서비스에 대항 , 오픈소스 프로젝트인 Jabber 출범 (Jeremie Miller)
•Jabber.org 커뮤니티를 통해서 프로토콜 지속적 개선
• IETF 에 의해 표준의 형태를 갖추게 됨
•XMPP 표준 제정•(RFC3920, RFC3921)
•GoogleTalk 출시

XMPP 프로토콜의특징특징 설명Open free, open, public 프로토콜 Standard IETF 표준Proven 수천개의 서버 , 수백만의 사용자 확보Decentral-ized
email 과 유사한 방식으로 확장
Secure SASL, TLS 등 규격 지원Extensible XML namespace 에 의해 자신만의 프로토콜을 코어위에 확장
Flexible IM 위에 네트워크 관리 , 콘텐츠 동기화 , 협업 도구 , 파일공유 , 게임 , 등 확장 가능
Diverse 수많은 회사 또는 오픈소스 프로젝트에서 다양한 응용서비스들을 출시하고 있음 .
