Abstract

The implementation of passive optical network in the access network will result in design of the network that have characteristics of broadband, long distance transmission, transparency. Particularly, optical technologies of WDM and WGR have made a new access network of WDM-PON. This paper proposes the algorithm that determines structural elements of a survivable optical access network, and simulates the cost of various scheme of proposed network architectures. Our results show that multistage star is the most cost effective scheme than the other architectures and show that network architecture designed by proposed algorithm provides survivability with single link and 1st node failure.

수동적인 광 네트워크로 구현되는 가입자망은 광대역, 장거리 전송, 투명성의 특성을 갖는 네트워크로 설계할 수 있다. 특히 WDM과 WGR의 기술은 WDM-PON의 새로운 가입자망 구성을 가능하게 한다. 본 논문은 생존성을 갖는 광 가입자망의 구성요소들을 결정하는 알고리즘을 제안하고 여러 구조들에 대한 비용을 분석하여 경제적이고 생존성이 있는 광 가입자망 구축 방향을 제시한다. 결과에 의하면 여러 광 가입자 구성 중에서 다중 성형 구조가 가장 경제적인 구조로 분석되었고, 제안한 알고리즘에 의해 설계된 구조에서 첫째 노드 장애와 모든 단일 링크 장애에 대한 생존성이 있음을 확인할 수 있었다.
