Abstract

This paper presents a new idea of structural design of the optical access network for IPOW(IP over WDM) services. More efficient network can be constructed, because the IP packets are transmitted directly to the WDM without going through an intermediate layer of networks. The wavelength Routing is based on a label switching technology. The ability to transmission of high volume traffics and QoS capability of the optical label switching directly to the end user of the IPOW optical internet networks is provided. As in AON(Active Optical Network) flexible bandwidth on demand subscribers is allocated. By the Simulation of the proposed optical access networks to measure the BER(Bits Error Ratio) at the end of the nodes the network characteristics are analyzed. These results are based on the design of efficient optical network.

본 논문에서는 IPOW(IP over WDM) 서비스를 위한 광가입자망의 구조설계에 관한 새로운 아이디어를 제공한다. IP 데이터를 중간계층을 거치지 않고 직접 WDM망을 통해 처리함으로써 보다 효율적으로 망을 구성할 수 있다. 파장단위로 하는 레이블 스위칭 방식을 기반으로 한 IPOW 광인터넷 기술을 이용하여 대용량 트래픽 전달 능력과 레이블 스위칭의 QoS 제공 기능을 네트워크 종단 사용자에게 직접적으로 제공한다. 또한 가입자 요구에 따라 액세스 밴드폭을 유동적으로 지원하는 AON(Active Optical Network) 형태의 광가입자망의 기능도 갖고 있다. 여기에서 제안한 IPOW 기반의 광액세스 네트워크는 시뮬레이션을 통하여 가입자망에 걸려 있는 끝단에서 BER(Bits Error Ratio) 특성을 분석하여 효율적인 광 가입자망의 설계 기준을 제시한다.
