Software defined optical network
Kloda, Tomáš ; Horváth, Tomáš (referee) ; Kočí, Lukáš (advisor)
This thesis is focused on explanation of software defined networking and communication via OpenFlow protocol with description of transmitted messages. This thesis deals with software defined optical networking, which describes combinations of OpenFlow with other technologies and methods to control the optical path. In another part, the thesis is focused on the description of the physical layer of optical backbone networks, where there is a description of multiplexers, DWDM technology and optical elements. This thesis also includes designs of software defined optical network with implementation of extended header for transmission in the optical domain. Outcome of this thesis are simulations, which include synchronization between the elements during initialization of software defined optical network with occurence of delay. At the end, the thesis is focused on simulations of the actual data transfer within the proposed software defined optical network.

Design of laboratory exercises in the field of network programmability
Dubovyi, Dmytro ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
The aim of the graduation thesis is to evaluate the current development in the field of SDN and the possibility of programmability of SDN elements using the application programming interface. The first theoretical chapter describes the following: the basic architecture of SDN, the traffic within SDN between its individual layers, the communication protocols Southbound interface and Northbound interface. The second chapter of the thesis deals with the programmability of SDN elements with the help of API. The third theoretical chapter describes the current development in the field of SDN. The practical part of the thesis is devoted to creation of two laboratory tasks dealing with the programming of the SDN API. Laboratory tasks include BIG-IP programming from F5 Network and routers from Arista Network. Programming is done using Python via REST API for BIG-IP, or eAPI for Arista EOS. The Ansible setup tool is also used for the same purpose.
