An emerging use case in software-defined networking is to provide efficient mapping of multiple virtual infrastructures (VIs) simultaneously over the same physical substrate (PS) which can increase the resource utilization of the PS, thus improving i

In this paper, we address the problem of traffic grooming and regenerator placement in a WDM optical network in which lightpaths are hop-constrained by physical impairments. The efficient placement of regenerators and electronic grooming equipment at

Current fixed grid wavelength routed networks are limited in terms of spectral efficiency due to the rigid nature of wavelength assignment. We propose the Flexible Optical WDM (FWDM) network architecture for flexible grid optical networks in which th

We introduce architectures to enable flexible-client functionality in software-defined transport networks for the first time, and propose an effective algorithm to provision time-varying traffic. Transponders with flexible-client interfaces improve s

An algorithm is proposed to map virtual infrastructures with survivability over T-SDN for the first time. The algorithm improves the traffic-carrying capacity of networks by provisioning at least 13% more demands than the baseline algorithms.

A conventional colorless and directionless ROADM architecture is modified to achieve contention-free performance without relying on external transponders and OTN switches, and can achieve a smaller size and lower power consumption than those of a con
