With the recent growth of network traffic demands, a high-capacity optical-path network based on reconfigurable optical add-drop multiplexers (ROADMs) is highly desirable. Among the various technologies available, extending the useable frequency band

Optical Fiber Communication Conference (OFC) 2022.
Efficient network design and control algorithms for fiber-granular routing networks are proposed. Routing performance of next-generation broad-bandwidth optical paths on fiber-granular routing networks with over 100×100 fiber-cross-connects is verif

Performance Evaluation of Dynamic Fiber-Granular Routing Networks with Next-Generation Optical Paths
Publikováno v:
26th Optoelectronics and Communications Conference.
The introduction of next-generation paths and fiber-granular routing to dynamic optical networks is studied. Due to the severe deterioration of statistical multiplexing effect, the fiber utilization ratio decreases by 50+% from current levels.

We propose a cost-effective metro network architecture with fiber-granular routing and path-granular add/drop operations together with its ILP-based design algorithm. The proposal alleviates the impact of filtering impairment while using already depl

We propose a novel RSA algorithm for dynamically-changing flexible-grid networks. The proposed scheme can suppress spectral fragmentation and adapt to traffic-distribution change. Extensive simulations show that the fiber-utilization efficiency is in

We propose an ultradense wavelength-division-multiplexing (WDM) network architecture that dramatically enhances channel accommodation density to achieve extremely high spectral efficiency. The trade-offs between high spectral efficiency and severe si

For efficient and dynamic path operations in transparent optical networks, routing and wavelength assignment (RWA) must be optimized in terms of not only link-resource utilization but also traffic distribution. In this paper, we propose a reinforceme
