Farsighted Spectrum Resource Assignment Method for Advance Reservation Requests in Elastic Optical Networks

Scheduling-Inspired Spectrum Assignment Algorithms for Mesh Elastic Optical Networks

Spectrum assignment has emerged as the key design and control problem in elastic optical networks. We have shown that spectrum assignment in networks of general topology is a special case of scheduling multiprocessor tasks on dedicated processors. Based on this insight, we develop and evaluate efficient and effective algorithms for mesh and chain networks that build upon list scheduling concepts.

Routing, Spectrum, and Transponder Assignment (RSTA) in Elastic Optical Networks

Backbone networks are evolving toward Elastic Optical Network (EON) architecture that allows a flexible and efficient use of spectrum resources. Flexibility in EONs is guaranteed also by emerging sliceable bandwidth variable transponders (SBVTs) that support the simultaneous generation of multiple optical carriers. Such carriers can be used to serve different lightpaths (i.e., slice-ability), o...

Dynamic Advance Reservation Multicast in Data Center Networks over Elastic Optical Infrastructure

We investigate dynamic advanced reservation (AR) multicast in data center networks over elastic optical infrastructure, and propose several algorithms to realize all-optical AR multicasting for data center backup and migration by considering request scheduling and RSA jointly.
