In recent times, optical networks, encompassing both access and backbone networks, have evolved into fundamental solutions offering high-speed communication rates, efficient resource allocation mechanisms, and a diverse array of services. Presently, advancements in dense wavelength division multiplexing (DWDM) technology enable next-generation optical telecommunications networks to achieve transmission speeds of 100 Gbps, 400 Gbps, or even 1 Tbps for a single optical path. The concept of elastic optical networks (EONs) facilitates the effective utilization of such high bitrates on optical paths to cater to users with varying demands, which may be significantly lower than the network’s capacity.

The presentation will discuss various ways to analyze the nodes of EONs. The author’s simulation environment will be discussed, as well as the proposed analytical models for determining traffic characteristics in the considered systems.

Maciej Sobieraj received the M.Sc. and Ph.D. degrees in electronics and telecommunications from the Poznan University of Technology, Poland, in 2008 and 2014, respectively. Since 2007, he has been working with the Faculty of Computing and Telecommunications, Institute of Communications and Computer Networks, Poznan University of Technology. He has coauthored of more than 60 scientific papers. His research interests include modeling multi-service cellular systems, switching networks and traffic engineering in TCP/IP networks.
