Abstract

This paper compares some architectures to achieve the optimized WDM architecture for all optical transport network, the comparison is presented in terms of the number of required wavelength and LT. These architecture types are PPWDM, SHWDM, DHWDM and fully optical WDM. Topology is a static ring network where the routing pattern is fixed and traffic pattern has uniform demand. This paper also proposes an algorithm for the wavelength assignment for a folly optical WDM ring network which has full mesh traffic pattern. The algorithm is based on heuristic algorithm which assigns traffic connections according to their respective shortest path. Traffic described here that is to be passed through can be routed directly within the optical layer instead of having the higher layer to handle it.

본 논문은 완전 광전달망에 적합한 네트워크 구조를 얻기 위해 몇 가지 구조들의 파장 수와 LT 수를 비교한다. 이 구조들은 PPWDM, SHWDM, DHWDM, 완정 광 WDM이며, 사용되는 토폴로지는 라우팅 패턴이 일정하고 트래픽 패턴이 균일한 정적 링 네트워크이다. 또한, 본 논문은 완전 메쉬 형태의 트래픽 패턴을 갖는 완전 광 WDM 링 구조에서 파장 할당 알고리즘을 제안한다. 파장 할당 알고리즘은 상위 계층과 관계없이 광 계층에서 직접 설정되는 트래픽을 최단의 경로를 따라 할당하는 학습적 알고리즘에 기초한다.
