“…These drawbacks in cost and wavelength contention are mitigated with the design of an N × M WSS as single component without internal wavelength contention. Numerous studies have demonstrated the N × M WSS as a single component based on LCOS technologies [21,22]. Additionally, the N × M WSS without contention offers potential benefits such as supporting multi-flow application [23] and the realization of CDC ROADM architecture [9].…”

Flexible optical networks will provide the required service diversity to manage unpredictable traffic patterns and growth. However, a key challenge is to quantify flexibility in order to indicate the associated performance of individual components and subsystems required to support networks and correlate it with other figures of merit. Measurable key performance indicators will aid the process towards the design and deployment of cost effective and efficient optical networks. Moreover, the design and placement of network elements within a network influences the resultant network-wide flexibility and performance. In this paper, we highlight critical design parameters for key optical components, optical transmission and switching subsystems using flexibility as an additional figure of merit. We derive models to measure the flexibility of key optical components, optical transmission and switching subsystems based on entropy maximization. Using these models, we evaluate flexibility and design trade-offs of the presented enabling technologies with other key performance indicators such as spectral efficiency, lightpath reach, total capacity, normalized cost, connectivity and others. This study provides an advanced and more informed set of design rules that quantify and visualize the different degrees of flexibility of enabling technologies and associated performance based on required specification and/or functionality.

“…and forwards the traffic to the aggregation and core tires. In this architecture, we assume the use of a 2 × K WSS, as the one demonstrated in [12]. Multiple interfaces (K ≥ 2) can be reserved to connect to the aggregation/core tier and support any topology (e.g., fat-tree and Quartz) for high scalability and resiliency.…”

SUMMARYMany detailed studies ranging from networking to hardware as well as standardization activities over the last few years have advanced the performance of the elastic optical network. Thanks to these intensive works, the elastic optical network has been becoming feasible. This paper reviews the recent advances in the elastic optical network from the aspects of networking technology and hardware design. For the former, we focus on the efficient elastic network design technology related to routing and spectrum assignment (RSA) of elastic optical paths including network optimization or standardization activities, and for the latter, two key enabling technologies are discussed: elastic transponders/regenerators and gridless optical switches. Making closely-dependent networking and hardware technologies work synergistically is the key factor in implementing truly effective elastic optical networks. key words: elastic optical network, network design, routing and spectrum assignment, elastic transponder
