Abstract:
The talk will concentrate on optimization of EONs. First, the most popular network services will be briefly discussed together with predictions on network traffic. Next, the general idea of Elastic Optical Networks will be introduced. The main part of the talk will be focused on optimization of EONs in the context of traffic patterns following from cloud computing and content-oriented networking. In more details, various approaches for optimization of EONs will be discussed including ILP (Integer Linear Programming) modeling, heuristic and metaheuristic algorithms. Some illustrating results obtained on real topologies will be reported to show performance of various optimization methods in the context of EONs.
Bio:
Krzysztof Walkowiak received the Ph.D. degree and the D.Sc. (habilitation) degree in computer science from the Wroclaw University of Technology, Poland, in 2000 and 2008, respectively. Currently, he is an Associate Professor at the Department of Systems and Computer Networks, Faculty of Electronics, Wroclaw University of Technology.
