MCF(Multi-Core Fiber)는 광 네트워크의 용량을 늘리는 유망한 공간 분할 다중화 기술 중 하나입니다. MCF 기반 네트워크에는 두 가지 과제가 있습니다. 하나는 인접한 두 광섬유 코어의 광 신호 품질을 저하시키는 코어 간 누화(XT)입니다. 다른 하나는 막대한 데이터 손실을 초래하는 링크 장애로부터 네트워크를 보호하는 것입니다. 다중 링크 장애로부터 보호하는 한 가지 방법은 물리적으로 분리된 링크를 백업 네트워크로 준비하는 것입니다. 확률적 보호는 특정 보호 실패 확률을 허용하여 보호 효율성을 향상시킵니다. 확률적 보호를 적용한 백업 네트워크 설계에 대한 기존 연구는 MCF 기반 네트워크를 대상으로 하지 않기 때문에 코어간 XT로 인한 보호 실패, 광자원의 과도한 소모 등의 문제가 발생한다. 이러한 문제를 해결하기 위해 본 논문에서는 MCF 광 경로 네트워크에 대한 XT 인식 백업 네트워크 설계 모델을 제안합니다. 제안된 모델은 확률적 다중 링크 장애로부터 네트워크를 보호합니다. 코어 간 XT로 인한 보호 실패 확률을 일정하게 허용하고 백업 네트워크에서 필요한 링크 수를 최소화하는 확률적 보호를 채택합니다. 우리는 확률론적 보호 요구 사항을 충족하고 모델을 정수 선형 계획법 문제로 공식화하는 알고리즘을 제시합니다. 우리는 제안된 모델을 더 큰 네트워크에 적용하기 위해 경험적 접근 방식을 개발합니다. 수치 결과는 제안된 모델이 기본 경로와 동일한 방식으로 백업 경로를 프로비저닝하는 전용 할당 모델보다 더 적은 수의 링크를 필요로 한다는 것을 보여줍니다.

Abstract: Multi-core fiber (MCF) is one of the promising space-division multiplexing technologies to increase the capacity of optical networks. MCF-based networks have two challenges. One is the inter-core crosstalk (XT) that degrades the quality of optical signals in two neighboring fiber cores. The other is network protection against link failures that cause massive data loss. One way to protect against multiple link failures is to prepare physically separated links as a backup network. Probabilistic protection improves the efficiency of protection by allowing a certain probability of protection failure. Existing studies on backup network design with probabilistic protection do not target MCF-based networks, which raises problems such as protection failure due to the inter-core XT and excessive consumption of optical resources. To address these problems, this paper proposes a XT-aware backup network design model for the MCF optical path networks. The proposed model protects the network against probabilistic multiple link failures. We adopt probabilistic protection that allows a certain probability of protection failure due to the inter-core XT and minimizes the required number of links in the backup network. We present an algorithm to satisfy the probabilistic protection requirement and formulate the model as an integer linear programming problem. We develop a heuristic approach to apply the proposed model to larger networks. Numerical results observe that the proposed model requires fewer links than the dedicated allocation model, which provisions the backup paths in the same manner as the primary paths.

AB - Multi-core fiber (MCF) is one of the promising space-division multiplexing technologies to increase the capacity of optical networks. MCF-based networks have two challenges. One is the inter-core crosstalk (XT) that degrades the quality of optical signals in two neighboring fiber cores. The other is network protection against link failures that cause massive data loss. One way to protect against multiple link failures is to prepare physically separated links as a backup network. Probabilistic protection improves the efficiency of protection by allowing a certain probability of protection failure. Existing studies on backup network design with probabilistic protection do not target MCF-based networks, which raises problems such as protection failure due to the inter-core XT and excessive consumption of optical resources. To address these problems, this paper proposes a XT-aware backup network design model for the MCF optical path networks. The proposed model protects the network against probabilistic multiple link failures. We adopt probabilistic protection that allows a certain probability of protection failure due to the inter-core XT and minimizes the required number of links in the backup network. We present an algorithm to satisfy the probabilistic protection requirement and formulate the model as an integer linear programming problem. We develop a heuristic approach to apply the proposed model to larger networks. Numerical results observe that the proposed model requires fewer links than the dedicated allocation model, which provisions the backup paths in the same manner as the primary paths.
