Optical signal processor
Heng Loong Lee,Dimitra Simeonidou +1 more
- 30 Aug 2001
TL;DR: In this paper, an optical signal processor for the optical processing of a digitally amplitude-modulated optical signal input was presented. But the authors did not specify the presence or absence of a predetermined digital bit pattern within the optical signal.

Protection by diversity in elastic optical networks subject to single link failure
Karcius D. R. Assis,Raul C. Almeida,Martin J. Reed,A. F. Santos,Henrique A. Dinarte,Daniel A. R. Chaves,H. Li,S. Yan,Reza Nejabati,Dimitra Simeonidou +9 more
TL;DR: In this paper , a mixed-integer linear programming (MILP) formulation is proposed to find an optimized unequally partitioning of connections' transmission rate among multiple disjoint paths, in order to provide dedicated protection and reduction in maximum number of slots on network and average bandwidth squeezing.

Energy aware planning of multiple virtual infrastructures over converged optical network and IT physical resources
Anna Tzanakaki,M. P. Anastasopoulos,Konstantinos Georgakilas,Dimitra Simeonidou +3 more
- 18 Sep 2011
TL;DR: An MILP model for virtualization of the underlying physical resources is proposed and validated achieving significant energy savings in energy efficient planning of multiple concurrent infrastructures incorporating integrated optical network and IT resources.
