Abstract

An IPTV has emerged as a widespread system when a realtime network and broadcasting system have progressed. Interestingly, it can also be organized with IPTV STBs and FC-AL for a high-quality TV content-sharing architecture. It is, however, not easy to configure a large community network with the FC-AL since it only has a 7-bit address space with supporting up to 127 users in the FC-AL single loop. We, therefore, propose an extendible FC-AL-based IPTV network architecture using a FC switch device. In this article, our suggested architecture shows a superb startup delay, such as less than 20msec. In addition, it demonstrates outstanding extendibility, such that the number of accomodable users increases almost linearly according to adding loops. Lastly, it reveals exceptional time-shifting hours, i. e., which supports more than 140 hours with 1000 users.

IPTV의 실시간 멀티미디어 컨텐츠 공유를 위해서는 안정적인 네트워크망과 멀티미디어 사용자 단말이 필요하다. 따라서 FC-AL과 IPTV STB를 이용하여 실시간 고화질 IPTV 컨텐츠 공유 아키텍처를 구성할 수 있지만, 프로토콜의 제한성으로 일정수 이상의 크기를 가진 커뮤니티 네트워크를 구성하기에는 어려움이 있다. 따라서 본 논문에서는 FC Switch를 활용하는 확장가능한 FC-AL 다중루프 기반의 IPTV 컨텐츠 공유 아키텍처를 제안한다. 제안된 아키텍처는 15 msec이하의 우수한 시작지연 시간을 보여주며, 루프수를 증가함에 따라 선형증가하는 공유 IPTV 프로그램수를 보여준다. 또한, 실험을 통하여 다중루프에서의 우수한 시간이동 서비스를 지원함을 보여준다.
