Routing among autonomous systems in Internet
Daněk, Michal ; Komosný, Dan (referee) ; Novotný, Vít (advisor)
Bachelor thesis describes the architecture of the Internet, its division into autonomous system and methods of their interconnection. Furthermore extensively describes routing mechanisms among autonomous system but also inside. More space is dedicated to routing protocols OSPF and BGP. At the end of the work is designed laboratory task for subject Network Architecture where this protocols are used.

Signal generator controlled by AVR
Wiesner, Jiří ; Steinbauer, Miloslav (referee) ; Roubal, Zdeněk (advisor)
The aim of this thesis was to design a universal function generator, which would find use for magnetizing and demagnetizing job, or for measuring hysteresis. The heart of the control module is an 8-bit microcontroller from Atmel, they are connected to the input/output peripherals, not least optocouplers for relay. Microcontroller communicates with the other module mounted DA converters using the SPI lines. At the exit so they can rise to any signals programmed into the MCU.

Data flow control in ISP network
Důbrava, Marek ; Jeřábek, Jan (referee) ; Koton, Jaroslav (advisor)
The thesis focuses on the control of data flow in networks of Internet service providers. The problem of aggregation and related overload network elements are shown. Theoretical section describes the standardized methods for managing data flow. The parameters associated with managing data flow are described for devices selected devices. The thesis displays measurements depicting to which extent the ECN algorithm occurs in practice. In the thesis is theoretically described HTB program, which is complemented by a newly described algorithm. The new algorithm is implemented into the program and tested on a real network ISP.

PC as a Border Router of an Internet Service Provider
Nowak, Michal ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This Bachelor Thesis tries to investigate structure of a network of medium size Internet Service Provider in Rousínov and surroundings, as well as tries to study demands of ISP that belongs to router's functionality. Thesis discuss mainly chosen distribution of the Linux operating system and used system services with regard to computer and system services performance and stability. Anyway an absolute majority of bandwidth will belong to IPv4 traffic, Router is IPv6 capable thought Tunnel Broker. Another components of thesis are basic authentication, blocking of unknown clients, traffic shaping and basics of theory about WAN interfaces bonding.

Wireless Security System
Matyáš, Jan ; Kočí, Radek (referee) ; Hanáček, Petr (advisor)
This thesis describes the design and implementation of portable wireless security device for monitoring object. The device consists of a control module allowing user to set and monitor current state of the measuring module which communicates with the control module wireless using the ISM band. The device is battery powered and highest possible battery life per charge is required.

Deploying Virtual Servers for ISP
Zelený, Jan ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
This thesis describes principals of virtualization based on the Xen project. Text focuses mainly on putting system into service for purpose of it's subsequent use by ISPs. The goal of this work is also to explore the possible usages of virtualized systems based on the Xen by ISPs. One of these possibilities will be specified to the point when it will by usable or it will be able to be developed independently of author of this work. This work also designs and mostly implements system, which can be used as a base for wide spectrum of of services, when installing these services doesn't effect the rest of the system.

Monitoring and regulation of water reservoir
Malý, Michal ; Fedra, Zbyněk (referee) ; Frýza, Tomáš (advisor)
This work is sight on production automatic machine for temperature adjustment and highs water level in reservoir. Automatic machine watch air temperature, water temperature in reservoir and temperatures on solar panel. Further watch water mark in reservoir by the help of rustless probe. By the help of this way adventitious data governs circulatory pump and solenoid valve for suffer waters. Work includes full technical documentation including PCB.

Adjustable timer for three-phase motor
Motyčka, Lukáš ; Petržela, Jiří (referee) ; Hruboš, Zdeněk (advisor)
The thesis describes several potential solutions of an adjustable timer, such as monostable multivibrators, asynchronous (ripple) and synchronous counters and microcontrollers. It also deals with issue of switching three-phase asynchronous motors with limit a high starting current on starting - star-delta switch, softstarter, frequency inverter. Particular attention is focused on the conceptual design of the timer using micro- controller Atmel (timer control unit), LCD (display device) and control switches. The microcontroller will be complemented by external 32,768 kHz watch crystal, necessary for real-time function - Real Time Counter (RTC). The cause for this choice is not only simplicity and clarity of control to the operator, but also reliability, low power consumption and also the price of the device itself.
