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.

Wavelength selective switching
Sikora, Vojtěch ; Kočí, Lukáš (referee) ; Münster, Petr (advisor)
Optical circuits switching is a rapidly growing area of photonic networks. With increasing requirements of photonic services only software defined networking allows flexible and effective networks creation. This bachelor thesis introduces technologies of optical circuits switching, especially wavelength selective switching node as reconfigurable optical add drop multiplexer used in wavelength division multiplexing networks. Using specialized software VPIphotonics the WSS 1x4 and ROADM for an interconnection between Prague, Brno, Ostrava and Vienna was designed.

SDN in LAN networks
Kříž, Daniel ; Hošek, Jiří (referee) ; Slavíček, Karel (advisor)
This bachelor's thesis is devoted to the problem of Software Defined Networks. It describes the concept of SDN, the OpenFlow protocol, which is an integral part of this issue, and lastly is mentioned the concept of NFV. The goal is to research this issue, gather information about the available open source controllers and choose the most suitable ones. Furthermore, a proposal for the implementation of the laboratory task and a~list of available components have to be created. The final task is to construct and test laboratory task and then with help of this knowledge create laboratory manual.

Virtual network topology design based on software defined networks
Moravcová, Klára ; Slavíček, Karel (referee) ; Novotný, Vít (advisor)
This Diploma thesis deals with virtualization of data networks, but mainly with concept of software-defined networking. Architecture, security risks and differences besides traditional networks are described within SDN framework. Description includes protocol OpenFlow, which is integral part of SDN concept. Brief summary mentions also NFV concept. The goal of this thesis is to determine available solutions, invent laboratory task and compile laboratory manual. Tables with currently available controllers and commutators for SDN were created and pattern of laboratoral task was realized within Mininet emulator and OpenDaylight controller. Laboratoral task itself is designed with aim to apprize students of subject of Network architecture with SDN concept and its real implementation.

VoIP Traffic Monitoring and Management in OnePK Enabled Networks
Antolík, Dávid ; Matoušek, Petr (referee) ; Ryšavý, Ondřej (advisor)
The main goal of this master's thesis is to apprise of principles of Cisco One Platform Kit based on software defined networks and with monitoring techniques in that type of networks. The focus is concentrated on monitoring the quality of Voice over IP communication. Next part of this thesis is a proposal and implementation of the extensible monitoring environment OneMon on the Cisco One Platform Kit. It is possible to extend OneMon environment using specific analyzers to monitor various types of network traffic. The part of this master's thesis is also implementation of VoIP traffic analyzer for SIP and RTP protocols. This analyzer provides information about phone calls and their quality in a monitored segment of a computer network.

Network virtualization - software defined networks
Veselý, Marek ; Krkoš, Radko (referee) ; Novotný, Vít (advisor)
The aim of work is a new trend in network architecture, called Software defined networks. Describes function of controller as the main device, which controlling the whole network. Further the communication between switch and controller is here, which controlling protocol OpenFlow. First chapter gently deal with principe of the VLAN networking. Further it is much more oriented with software defined networks, where the main principe is described. Protocol OpenFlow is described in deatail, as his functions are discussed too. There are also advantages and disadvantages and possibility to use this network in university campus.

Lawful Interception in Software Defined Networks
Franková, Barbora ; Ryšavý, Ondřej (referee) ; Polčák, Libor (advisor)
This thesis covers utilization of software defined networks for lawful interception purposes. Based on specific implementation of lawful interception system SLIS developed by Sec6Net group, suggests improvements aiming at more precise identification of intercepted users and better effectivity of system resources. First aim is achieved by implementation of a new module for dynamic identification component while the other one alters configuration mechanism for probes and OpenFlow switches.

SDN Routing According to Transmitted Content
Gavryliuk, Olga ; Franková, Barbora (referee) ; Holkovič, Martin (advisor)
This works main point of focus is routing in software defined networks, which allow routing based on transfered packets. For accomplishing this task it was necessary to create a detection mechanism, that finds the connection within the OS which needs priority handling. New connections are sent via a routing aplication which is running on the SDN controller POX. The controller divides applications based on two criteria: The application requiring the largest bandwidth and the application requiring the fastest route. For this purpose four algorithms for routing data based on application preferences were designed and implemented. The applications were implemented in the Python language and they were tested in the simulation tool Mininet.

A Network Control Language for OpenFlow Networks
Antolík, Dávid ; Veselý, Vladimír (referee) ; Ryšavý, Ondřej (advisor)
The main goal of this bachelor thesis is to design and implement a high-level language for declarative configuration of Open-Flow networks. The compiler of the language, data model and interpreter were implemented employing Trema as the underlaying Open-Flow controller. The implementation was tested in a virtual network environment and it was shown that it is fully functional for basic network configurations.
