WDM(Wavelength Division Multiplexing) 기술은 광섬유에서 10Gbps 속도로 여러 파장을 제공하는 새로운 광 기술입니다. IP 패킷이 WDM 네트워크에서 직접 전달되는 WDM 네트워크상의 IP(인터넷 프로토콜)는 차세대 인터넷을 위한 인프라를 제공할 것으로 기대됩니다. IP over WDM 네트워크의 경우 WDM 보호 메커니즘은 매우 안정적인 네트워크(즉, 링크/노드 장애에 대한 견고성)를 제공할 것으로 예상됩니다. 그러나 기존 IP는 라우팅 기능을 통해 신뢰성 메커니즘도 제공합니다. 본 논문에서는 먼저 WDM 네트워크의 보호 기능을 갖춘 IP over WDM 네트워크를 설계하기 위한 최적화 문제를 공식화하여 높은 신뢰성을 갖춘 IP over WDM 네트워크를 얻을 수 있습니다. 우리의 공식은 혼합 정수 선형 문제(MILP)를 초래합니다. 그러나 MILP는 소수의 변수(이 경우 노드 및/또는 파장)에 대해서만 풀 수 있는 것으로 알려져 있습니다. 따라서 우리는 두 가지 경험적 알고리즘을 제안합니다. 최소 홉 우선 and 최대 트래픽 우선 백업 lightpath에 파장을 할당하기 위해 접근합니다. 우리의 결과는 min-hop-first 접근 방식이 신뢰할 수 있는 네트워크를 구축하는 데 더 적은 파장을 사용한다는 것을 보여줍니다. 즉, 모든 lightpath는 WDM 보호 메커니즘을 사용하여 보호될 수 있습니다. 그러나 우리의 최대 트래픽 우선 접근 방식은 링크 실패로 인해 IP 라우터에서 증가된 트래픽 양을 절약할 수 있다는 점에서 좋은 선택이기도 합니다.

Abstract: A WDM (Wavelength Division Multiplexing) technology is a new optical technology, providing multiple wavelengths at the rate of 10 Gbps on the fiber. IP (Internet Protocol) over WDM networks where IP packets are directly carried on the WDM network is expected to offer an infrastructure for the next generation Internet. For IP over WDM networks, a WDM protection mechanism is expected to provide a highly reliable network (i.e., robustness against the link/node failures). However, conventional IP also provides a reliability mechanism by its routing function. In this paper, we first formulate an optimization problem for designing IP over WDM networks with protection functionalities of WDM networks, by which we can obtain IP over WDM networks with high reliability. Our formulation results in a mixed integer linear problem (MILP). However, it is known that MILP can be solved only for a small number of variables, in our case, nodes and/or wavelengths. We therefore propose two heuristic algorithms, min-hop-first and largest-traffic-first approaches in order to assign the wavelength for backup lightpath. Our results show that the min-hop-first approach takes fewer wavelengths to construct the reliable network, that is, all of lightpaths can be protected using the WDM protection mechanism. However, our largest-traffic-first approach is also a good choice in the sense that the approach can be saved the traffic volume increased at the IP router by the link failure.
