Highly Available Scalable CMS in the Java EE Environment
Šramko, Samuel ; Kolář, Dušan (referee) ; Burget, Radek (advisor)
This thesis deals with the background of the design of a highly available, scalable and modular content management system based on the Java EE platform and the OSGi framework and with the implementation of the designed system. It describes the design and implementation of the application decomposition to modules, their communication and bindings. Finally, it presents the results of the application testing and proposes available extensions of the application.

Load Balancing in OpenFlow Networks
Marciniak, Petr ; Ryšavý, Ondřej (referee) ; Grégr, Matěj (advisor)
The aim of this thesis is to develop a load balancing tool for OpenFlow networks. Software-defined networking (SDN) principles are introduced (OpenFlow protocol used as an example) and compared to the legacy routing and switching technology. Openflow is the first protocol/API enabling communication between the control and infrastructure planes of the software-defined networking model. Key features of the protocol are described and several OpenFlow controllers are introduced. Current best practices in computer networks load balancing are discussed as well. The load balancing application development process is described including the test laboratory setups - Mininet (SW) and OFELIA (HW). The application test results are evaluated and possible further enhancements to the program are discussed.

Dynamic Metric in OSPF Networks
Mácha, Tomáš ; Orgoň, Miloš (referee) ; Bešťák, Robert (referee) ; Novotný, Vít (advisor)
Masivní vývoj Internetu vedl ke zvýšeným požadavkům na spolehlivou síťovou infrastrukturu. Efektivita komunikace v síti závisí na schopnosti směrovačů určit nejlepší cestu pro odesílání a přeposílání paketů ke koncovému zařízení. Jelikož OSPF v současné době představuje jeden z nejpoužívanějších směrovacích protokolů, jakýkoli přínos, který by pomohl udržet krok s rychle se měnícím prostředí Internetu, je velmi vítán. Významným omezením OSPF protokolu je, mimo jiné, absence informovanosti algoritmu pro výpočet metriky o aktuálním vytížení linky. Tato vlastnost představuje tzv. slabé místo, což má negativní vliv na výkonnost sítě. Z tohoto důvodu byla navržena nová metoda založená na dynamické adaptaci měnících se síťových podmínek a alternativní strategii OSPF metrik. Navržená metoda řeší problém neinformovanosti OSPF metriky o síťovém provozu a nevhodně vytížených linek, které snižují výkonnost sítě. Práce rovněž přináší praktickou realizaci, kdy vlastnosti nové metody jsou testovány a ověřeny spuštěním testů algoritmu v reálných zařízeních.

Design of the slab bridge
Strouhalová, Petra ; Krejčík, Vladimír (referee) ; Klusáček, Ladislav (advisor)
This thesis deals with design and solution of road slab bridge structure. Draft prestressing force is processed using the load balancing, the thickness of the slab is consedered in five variants. The aim of this thesis is to determine which option is appropriate for prestressing and which not and subsequently one selected variant design.

Methodology of optimal usage of load balancing in data center environment
Nidl, Michal ; Gála, Libor (advisor) ; Hořejš, Jan (referee)
The following master thesis is focused on creation of methodology for optimal usage of load balancing in data center environment. Thesis is divided into eight chapters. The first chapter describes the reasons why to deal with this topic further. The second chapter summarizes the state of load balancing. This chapter is based on research of already elaborated thesis which were focused on load balancing in different ways. The third chapter summarizes load balancing including its key principles. The fourth chapter describes an actual state of load balancing in data center environment. An observation of real usage of load balancing in selected data center was used for the main purpose of this chapter. The fifth chapter consists of analysis of the currently existing methodologies which are used from the infrastructure projects purpose. The sixth chapter deals with creation of methodology for optimal usage of load balancing in data center. The seventh chapter evaluates usage of methodology by applying of this methodology to real practical example of implementation of load balancing. The eighth chapter summarizes all detected conclusions.
