ISP Network Optimalization
Čech, Ondřej ; Podermański, Tomáš (referee) ; Grégr, Matěj (advisor)
Bachoelor's thesis is focusing on analysis of network local ISP, detecting actual problems and offering a solution for founded problems. There were problems with broadcast-storm, private address space, RSTP protocol settings and DHCP spoofing. The following changes were introduced: OSPF routing, RSTP override, automatic backup, client separation using DHCP. There has been a reduction in broadcast traffic and associated broadcast-storm.

Design of reliable VLAN-based enterprise data nework
Vrablic, Pavol ; Krkoš, Radko (referee) ; Novotný, Vít (advisor)
The main aim of this work is to identify the potential issues within a robust network to provide a highly reliable and fault free service – with a smooth and reliable functionality of critical services. This work contains new methods of branch networking and virtualization that is increasingly used in enterprise networks. It is important to note that computer clustering provides the functionality of critical services that can surpass potential partial failures and network QoS; which overall, achieves a high quality and reliable service.

Application of virtual local area networks for effective and flexible data network design
Brázda, Libor ; Burda, Karel (referee) ; Novotný, Vít (advisor)
This thesis is aimed to the problems of virtual local networks. In the first chapters are explained both basic and advanced methods of designing and management of virtual LAN networks. The following chapters are dedicated to the methods of effective management VLAN networks and to the protocol Spanning Tree, preventing formation of loops in redundant networks, and their exploitation in VLANs. The practical part describes the application of the implementation of the technology of virtual local networks in experimental network, containing various types of devices. Based on this theory, a laboratory assignment has been designed for the training of the students in solving such problems. The scope of the laboratory assignment is divided into simpler partial tasks, which even a less advanced student should be able to configure and test.

New trends in data network design
Hlavatý, Jindřich ; Zeman, Václav (referee) ; Novotný, Vít (advisor)
are used. In the theoretical part I analyse some basic network protocols and their gradual development, VLANs and Spanning Tree Protocol, MPLS protocol and other. There are described parameters for the design of new networks and the models networks and their various are used, the network with a new architecture and a software-defined network (SDN),too. The practical part deals with designed laboratory exercises for teaching students. The laboratory experiments are always divided into several tasks. They are formed even students ignorant or less familiar with the issue could configure and test it.

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.

Software Controller for OpenWrt Based Wi-Fi Access Points
Jašíček, Petr ; Krajsa, Ondřej (referee) ; Ilgner, Petr (advisor)
The aim of this thesis was to create a web application used for centralized management and configuration of wireless networks on access points running on OpenWrt distribution. The reader is acquainted with common principles of wireless networks including description of existing solutions for their centralized management. After that the thesis introduces the reader to OpenWrt distribution and to a method of its configuration using UCI model. The reader is then introduced to the main technologies used in this thesis. Author further describes architecture, user interface and implementation of the web application. The created web application is platform agnostic and provides easy way to manage and configure access points with OpenWrt distribution.

Revision & improvement of structural cabling in the building of the Faculty of Music, Janáček Academy of Music and Performing Arts
Špičák, Jan ; Novotný, Vít (referee) ; Sedlák, Petr (advisor)
The objective of this bachelor’s thesis is to perform an analysis of structural cabling in the building of the Faculty of Music, Janáček Academy of Music and Performing Arts, and to propose an improvement of mentioned cabling system to achieve current industry standards of stability & reliability. Both horizontal cabling routes and physical network topology are taken into account; network hardware recommendation with its setting is also included, although mentioned newly purchased equipment is not strictly required. In the conclusion, the thesis deals with an economic evaluation of the proposed solution as a major decision-making factor for the chosen public institution.
