본 논문에서는 대용량 광WDM(Wavelength Division Multiplexing) 네트워크에서 간단하고 빠른 라우팅 방법에 대해 설명합니다. 향후 증가하는 트래픽 부하를 수용하기 위해서는 대용량 WDM 네트워크가 필요합니다. 이 대용량 WDM 네트워크에서는 각 링크에 많은 광섬유가 있으며, 이 광섬유를 통해 엄청난 양의 광 데이터를 동시에 전송할 수 있습니다. 라우팅 및 파장 할당(RWA)을 포함한 파장 예약을 통해 광 데이터를 전송하기 위해 광 경로가 구성됩니다. 기존 RWA 방법은 각 광섬유에서 사용 가능한 파장에 대한 많은 정보를 처리해야 하기 때문에 RWA 문제를 적시에 해결하기가 어렵습니다. 즉, 대용량 WDM 네트워크에서는 전기적 처리가 병목 현상이 된다. 따라서 대용량 WDM 네트워크에서는 간단하고 빠른 RWA 방식이 필요하다. 본 논문에서는 축소된 정보를 네트워크 맵으로 고려하는 간단하고 효과적인 RWA 방법을 제안한다. 목표는 다중 광섬유를 효과적으로 사용하여 네트워크 성능을 향상시키는 것입니다. 하나의 요청에 대해 매우 짧은 시간에 전환 작업을 수행해야 하므로 복잡한 처리는 데이터 전송에 적합하지 않습니다. 또한, 상세한 네트워크 정보를 자주 수집하는 것은 실용적이지 않습니다. 제안하는 파장 할당 방법은 기존 방법보다 파장을 더 균일하게 할당하므로, 제안하는 라우팅 방법은 각 파장 상태에 대한 세부 정보를 고려하지 않고도 경로를 선택할 수 있다. 제안하는 라우팅 방법은 지역 정보와 축소된 네트워크 정보만 필요하다. 본 논문에서는 제안된 라우팅 방법이 컴퓨터 시뮬레이션을 통해 대용량 광 WDM 네트워크에 적합한 솔루션을 얻을 수 있음을 보여줍니다. 제안된 RWA 방법은 다른 단순 RWA 방법에 비해 손실 확률을 획기적으로 향상시킨다. 또한 이 문서에서는 조정 가능하거나 고정된 파장 변환 기능을 갖춘 두 가지 유형의 광 스위치에 대해 설명합니다. 상대적으로 기술 수준이 낮은 파장 변환기는 대용량 WDM 네트워크에서 제안된 RWA 방식을 사용하면 효과적입니다. 본 논문은 대용량 광 WDM 네트워크에는 복잡한 라우팅 방법이 필요하지 않음을 보여줍니다.

Abstract: This paper discusses a simple and speedy routing method in large-capacity optical Wavelength Division Multiplexing (WDM) networks. The large-capacity WDM network is necessary to accommodate increasing traffic load in future. In this large-capacity WDM network, each link has many fibers and a huge amount of optical data can be transmitted through these fibers simultaneously. Optical path is configured for transmitting optical data by wavelength reservation including routing and wavelength assignment (RWA). Since traditional RWA methods have to treat much information about available wavelengths in each fiber, it is difficult to resolve RWA problem on time. In other words, the electrical processing becomes the bottleneck in the large-capacity WDM network. Therefore, a simple and speedy RWA method is necessary for the large-capacity WDM network. In this paper, we propose the simple and effective RWA method which considers reduced information as Network Map. The objective is to improve the network performance by using multiple fibers effectively. The complex processing is not suitable for data transmission because the switching operation must be done in very short time for one request. In addition to this, it is not practical to collect detailed network information frequently. The proposed wavelength assignment method assigns wavelength more uniformly than traditional method, and therefore, the proposed routing method can select routes without considering detailed information about each wavelength state. The proposed routing method needs only local information and reduced network information. This paper shows that the proposed routing method can get suitable solution for large-capacity optical WDM networks through computer simulations. The proposed RWA method drastically improves the loss probability against other simple RWA methods. This paper also describes two types of optical switches with tunable or fixed wavelength conversions. The wavelength converters with relatively low technology becomes effective with the proposed RWA method in the large-capacity WDM network. This paper reveals that complex routing methods are not necessary for large-capacity optical WDM networks.
