Measuring of System Load in Embedded Linux
Skopal, Jakub ; Korček, Pavol (referee) ; Viktorin, Jan (advisor)
The bachelor thesis describes the quantities which characterize the load of the embedded systems based on the Linux kernel. The library was designed and implemented to observe the load of the system in order to facilitate and unify the observation of individual quantities and their reciprocal coherence. Due to the lack of external dependencies of the library the memory requirements are low. To demonstrate the use of the implemented library, a program was designed which depicts the graphs of measured quantities in real time on a remote computer.

Library for Fast Network Traffic Processing
Vokráčko, Lukáš ; Viktorin, Jan (referee) ; Kořenek, Jan (advisor)
This thesis is focused on time-critical operations in context of computer networks. Processed operations are packet classification, specially one-dimensional classification, longest prefix matching using binary search on prefix length and TreeBitmap, pattern matching using Aho-Corasick, regular expression matching and packet header analysis and extraction. Purpose of this work is to design API for library implementing these operations. Implementation speed of these operations is measured on Intel and ARM platforms.

Automatic Testing of the BeeeOn System
Wolfert, Richard ; Hujňák, Ondřej (referee) ; Viktorin, Jan (advisor)
This Master's thesis is about analysis of Internet of Things project BeeeOn, design and production of unit, integration and system tests and their automation by utilization of Continuous integration system Jenkins CI. The theoretical part is devoted to software testing fundamentals and Continuous integration systems. The main point of this thesis is about specification and description of BeeeOn system, its requirements for automatic testing and its implementation. In conclusion, the results of this work and expansion possibilities are discussed.

Modular Framework for Sensor Data Processing
Rašovský, Martin ; Viktorin, Jan (referee) ; Korček, Pavol (advisor)
The bachelor thesis deals with the issue of concept and realization of the server application for a smart home system, where the purpose of the whole application is in the form of framework that offers the calculations and possible actions among the system. The theoretical part of this thesis analyses and describes architecture of the existing system with the focus on the server part. From previous analysis is derived the concept of the application . The concept describes the way of communication with other nodes of the system, storing data and configuration . Further the thesis selects the used technologies and deals with the implementation details of the project. Furthermore the thesis documents testing , the integration into described smart home system and results of functionality of the application . In the conclusion is discussed further possible expansions of the project.

Server for Collecting Sensor Data and Control of Active Elements
Halaj, Jozef ; Hujňák, Ondřej (referee) ; Viktorin, Jan (advisor)
Bachelor's thesis aims on communication with remote sensors and active elements in the smart home system called BeeeOn. The individual parts of the BeeeOn system are described with respect to the current insufficient communication principle and implementation. For communication with BeeeOn gateways, the WebSocket technology is used. It allows communication on netwoks with a restricted access to privileged ports. The implemented server is in principle capable of serving a high number of BeeeOn gateways that works as a bridge among the server and the remote sensors. The communication is secured with SSL/TLS, it uses confirmation mechanism to guarantee reliability and it is easily extendable by other protocol messages. It enables the system to send asynchronous commands to the BeeeOn gateway and to the connected devices. The server is implemented in C++ language. The most common communication scenarios were tested by automated tests.

Acceleration of NAT and Packet Filter in FPGA for 10G Networks
Orsák, Michal ; Kořenek, Jan (referee) ; Viktorin, Jan (advisor)
This thesis deals with the design of a universal hardware acceleration unit for packet filtering in FPGA for 10G networks. Maximum count of rules is greatly increased by the use of external QDR-II memory. Parameters of accelerator are suitable for NAT, packet filtering and lawful interceptions. The platform uses variable number of processing units. One of them controls accelerator by USB port. The rest is used for network processing.

Communication on the ADSP-SC58x Chip
Havran, Jan ; Korček, Pavol (referee) ; Viktorin, Jan (advisor)
This projects describes the design of communication between SHARC and ARM cores on ADSP-SC58x platform, concretely between bare-metal and Linux applications on ADSP-SC589 chips. There are outlined several available technologies for data transfer, such as MCAPI, MDMA or shared memory. There are also designed and implemented new communication principes based on current implementations of these technologies.

Integration of Sensors and Actors into the BeeeOn System
Bednařík, David ; Korček, Pavol (referee) ; Viktorin, Jan (advisor)
In this bachelor thesis, the task was to acquaint with components of smart home from these vendors Belkin WeMo, Philips Hue, BeeWi, to study their communication protocol and create modules to BeeeOn system to control them. In the theoretical part of thesis is described how the BeeeOn system works and how the single device from mentioned manufacturers behaves and communicates. In the practical part, it is mentioned the way of extension of BeeeOn Gateway application to modules for control the smart home devices. This part also includes the methods of testing and verification of accuracy of implementation.

Emulator for Intelligent Home End Stations
Brychtová, Hana ; Viktorin, Jan (referee) ; Korček, Pavol (advisor)
This thesis covers design and implementation of an application with a graphic user interface emulating the behaviour of end stations for intelligent home. These devices are used for measuring physical quantities and controlling switches. The application is implemented in C++ using Qt Framework. The final product is an application which provides a simple way of testing in a friendly user interface. The main benefit is in enabling a parallel developement of the server application and the developement of the hardware end station devices.
