BigData Approach to Management of Large Netflow Datasets
Melkes, Miloslav ; Ráb, Jaroslav (referee) ; Ryšavý, Ondřej (advisor)
This master‘s thesis focuses on distributed processing of big data from network communication. It begins with exploring network communication based on TCP/IP model with focus on data units on each layer, which is necessary to process during analyzation. In terms of the actual processing of big data is described programming model MapReduce, architecture of Apache Hadoop technology and it‘s usage for processing network flows on computer cluster. Second part of this thesis deals with design and following implementation of the application for processing network flows from network communication. In this part are discussed main and problematic parts from the actual implementation. After that this thesis ends with a comparison with available applications for network analysis and evaluation set of tests which confirmed linear growth of acceleration.

FITKit Virtualization
Vavruša, Marek ; Korček, Pavol (referee) ; Vašíček, Zdeněk (advisor)
Thesis presents a method of FITkit hardware platform virtualization. First part describes an extension of the libkitclient library to support virtual devices and discusses a protocol design for FITkit device sharing in the IP networks. The protocol is extended to offer an automatic device discovery in local network based on UDP multicast. The second part of the thesis presents an architecture for a remote compilation of FITkit platform binaries and the implementation in the fcmake and QDevKit. The last chapter summarizes implemented tools and presents possible future extensions.

System for Sharing Scanners over Network
Richter, Martin ; Rychlý, Marek (referee) ; Očenášek, Pavel (advisor)
The purpose of this master's thesis is creation of a system capable of sharing scanners over computer network. The target scanner interfaces are TWAIN and WIA on Microsoft Windows operating system, and SANE on GNU/Linux. C++ programming language, Boost libraries and Qt framework were used to implement the programming part of this work. Several smaller helper libraries were implemented that are useful even outside this work, most notably TWAIN++ framework. The resulting system enables the user to share scanners over network, and scan using any of the aforementioned interfaces.

Design and Implementation of Network Application for Audit and Monitoring of Computers
Krym, David ; Veselý, Zdeněk (referee) ; Dydowicz, Petr (advisor)
This diploma thesis deals with design and implementation of a network application for monitoring of computers for a chosen company. The application allows administrators to automate the gathering of hardware and software information. The purpose of the application is also to monitor hardware values, such as processor temperature or harddisk free space. The design uses client-server architecture. Three applications were created: server, client and graphical management console.

GSM gate for PLC systems
Kadaňka, Karel ; Cipín, Radoslav (referee) ; Knobloch, Jan (advisor)
The master´s thesis describes the initial design of communication module for industrial automation purposes which can transmit short status messages via the GSM network informing about the status of the connected device to a predefined telephone number. In the first part, the communication protocols are describe and a market survey is carried out. Then follows the evaluation of the market survey and the justification of construction of the device. The following chapters are devoted to the description of the device being developed, its individual components and program description and testing prototype.

Realization of the Car2X and Car2Car communication device
Štohanzl, Milan ; Sloupenský, Marek (referee) ; Prokopec, Jan (advisor)
This work explores possibilities of Car2Car and Car2X communication. It contains survey of system properties, types of transmission messages, etc. It represents architecture of the system and deals with technical expectations and limitations of system. In the light of the fact that this work is created in the time, when development of this system hasn’t finished yet, the work doesn’t contain details which would allow deeper technical view about area of vehicular communication. The work also deals with the possibility of realization of device, communicating with a similar standard. Like the most suitable standard was chosen an IEEE 802.11a. Mobile unit has been realized by single board computer Mini 2440 and communication has been realized by WiFi module OWS451i, which works as AT modem. Mini 2440 and infrastructure server are based on Linux operation system.
