Bonjour and Zeroconf

Bonjour 란?

봉쥬르? 본져? 한국말로 어떻게 불러야할지 좀 거시기하군요. 많이 보신듯한 단어일겁니다.
원래는 Apple에서 랑데뷰로 불렸었는데 상표권문제로 봉쥬르로 명명되었다고합니다.
Bonjour는 Apple에서 만든 Zero Configuration Networking 프로토콜로써 IP 네트워크 상에서 컴퓨터, 주변기기 및 서비스를 자동으로 검색하는 서비스를 말합니다.
(참고, Zeroconf는 LGPL  이기때문에 다른 플랫폼/OS에서도 bonjour서비스를 볼수있다)

아이폰, 아이패드용 어플에 이 기술을 적용해 멋진 어플을 만들어 보는것도 좋을거 같습니다. 소규모 내부 클라우드 시스템 구축도 가능하지 않을까요?

다음은 애플에서 제공하는 샘플코드입니다.
서버와 클라이언트 두 개의 소스로 나누어져 있고 서버 측의 이미지를 클라이언트에서 볼 수 있는 프로그램입니다.
