초록
본 논문에서는 IP-TV 서비스 시스템 구성 및 지원 기술들에 대해서 알아보고, IP-TV 서비스를 위한 광대역통합망 전달계층 구조를 제시한다. 그리고 IP-TV 서비스를 위한 전달망 제어구조 및 제어 메커니즘을 제안한다. 또한 DWDM(Dense Wavelength Division Multiplexing) 전달망에서의 unicast RWA(Routing and Wavelength Assignment) 문제와 MCRWA(Multicast RWA) 문제 해결을 위해 각각 MW-MIPR(Multi-Wavelength Minimum Interference Path Routing) 알고리즘과 본 논문에서 제안한 VS-MIPMR(Virtual Source-based Minimum Interference Path Multicast Routing) 알고리즘을 적용한다. 최종적으로 유니캐스트 및 멀티캐스트 서비스 모델에서 이러한 알고리즘들의 성능과 효율성을 평가하고 분석한다.
Abstract
In this paper, we observe system configuration and supporting techniques of IP-TV services and present transport layer structure of broadband convergence network (BcN) for IP-TV services. And we propose the control architecture and mechanism of transport network. Moreover, we apply Multi-Wavelength Minimum Interference Path Routing (MW-MIPR) and Virtual Source-based Minimum Interference Path Multicast Routing (VS-MIPMR) proposed in this paper to resolve unicast and multicast routing and wavelength assignment (RWA) problem in DWDM transport network, respectively. Finally, we evaluate and analyze the performance and efficiency of these algorithms in unicast and multicast service model.
