본 논문에서는 OXC(Optical Cross Connect)를 사용하여 다중 파장 분할 다중화(WDM) 자가 치유 링 시스템을 상호 연결하는 광 전송 네트워크의 최적 설계 방식을 제안합니다. 이러한 링 시스템을 상호 연결하기 위해 각 허브에 필요한 OXC 수를 계산하기 위해 가상 메시 네트워크가 생성됩니다. 여기서 각 OP(광 경로)는 여러 인접 링("링"은 네트워크 토폴로지에서 원으로 정의됨)을 통과합니다. )은 허브 목록을 기반으로 결정됩니다. 그런 다음 주어진 수요를 수용하기 위해 OXC 및 링 시스템을 포함한 시설의 전체 비용을 최소화하는 정수 프로그래밍 기반 설계 문제가 공식화됩니다. 이 문제를 해결함으로써 우리는 각 링에 필요한 링 시스템 수, 각 개별 양방향 링 시스템 내의 파장 할당, 각 허브에 필요한 OXC 수 및 각 OP에 할당할 용량을 동시에 최적화할 수 있습니다. 수치적 예는 OADM의 비용이 OXC의 비용보다 낮고 OXC 대 광섬유 비용 계수 비율이 충분히 큰 경우 링 기반 네트워크가 메시 복원 가능 네트워크보다 비용 효율적이라는 것을 보여줍니다.

Abstract: This paper proposes an optimal design scheme for photonic transport networks that interconnect multiple wavelength division multiplexing (WDM) self-healing ring systems by using optical cross connects (OXCs). To calculate the number of OXCs required in each hub to interconnect these ring systems, a virtual mesh network is generated, on which the route of each optical path (OP) going through multiple adjacent rings ("ring" is defined as circle in network topology) is determined based on a list of hubs. An integer-programming-based design problem is then formulated that minimizes the overall cost of facilities including OXCs as well as ring systems to accommodate a given demand. By solving this problem, we can simultaneously optimize required number of ring systems in each ring, wavelength assignment within each individual bidirectional ring system, required number of OXCs in each hub, and capacity to be allocated to each OP. Numerical examples show that the ring-based network is more cost-effective than the mesh restorable network when the cost of an OADM is lower than that of an OXC, and the OXC-to-fiber cost-coefficient ratio is sufficiently large.
