Automated testbed for SIL/PIL testing of embedded application using FPGA
Prusák, Lukáš ; Burian, František (referee) ; Arm, Jakub (advisor)
The master's thesis deals with designing a testbench for a selected soft-core processor NEORV32 with a RISC-V architecture for simulations of embedded applications in an FPGA environment. The testbench was created in the Vivado environment with the aim of extending it to a testing and validation framework. Basic modules such as GPIO, PWM, UART, and PC were selected and implemented. Several test scenarios have been designed for these modules. The testbench has also been supplemented with additional scripts, to create hierarchically correct project setup and test execution. The work also suggests a few possible ways to improve and expand the testbench.

Simulation scenarios in NS2 demonstrating knowledge obtained in the MPKT course
Mašek, Jan ; Mlýnek, Petr (referee) ; Jeřábek, Jan (advisor)
The aim of the bachelor´s thesis is to develop simulation tasks for modeling of data networks. The tasks will be used in the course Modern communication technique (MKPT). The networks are simulated in the environment of Network Simulator 2 (NS2). A brief description of program environment NS2, as well as basics of Tcl language is mentioned in the introduction. Described is the possibility of simulation HTTP protocol in NS2 using OTcl PagePool classes. Totally six proposed tasks form the core of the thesis. The first task uses PagePool/Math and displays the simplest communication between client, server and cache. Next task uses PagePool/CompMath and it shows the communication between client, cache, Web server, FTP server and FTP client. The task, that uses PagePool/WebTraf class, simulates communication between two clients and three servers. The last three tasks are of different topologies and course of communication using PagePool/ProxyTrace. The exercises of this class are the most complicated and their input files allow defining whole communication. The outputs of exercises are given in graphs, log files of HTTP communication and the last task contains detailed instructions.

Control of network operation generator from OPNET Modeler environment
Bartl, Milan ; Hošek, Jiří (referee) ; Molnár, Karol (advisor)
In this work an interface between network simulator OPNET Modeler and network operations generator IxChariot is described. The goal is to control the generator by data from an OPNET modeler simulation. More accurately the generator is supposed to produce a data flow with desired settings of DSCP field, which is used to support quality of service mechanism. The goal can be achieved by two possible approaches: using IxChariot TCL API or IxChariot C API. Both of these approaches are described and conclusions are made at the end.

Wireless model 802.11 in NS2
Botta, Miroslav ; Kubánková, Anna (referee) ; Šimek, Milan (advisor)
Theme of this work is simple wireless simulation Network Simulation 2 tool. The work consists of more parts. In the first section is basic theory about Wi-Fi networks, they types and standards and describes how useful can it be in practical life. In the second section there is a short annotation for programming in TCL language and possibilities of NS2 for simulating wireless networks. In the end there is a complex simulation of this network. In the third part there are two complex tasks where the information’s are drawn from the previous two parts.

Automatic configuration of intermediate networking devices used in Cisco academy
Verner, Lukáš ; Jeřábek, Jan (referee) ; Komosný, Dan (advisor)
his semestral´s thesis deals with proposal and system implementation for automatic configuration of Cisco network devices. This system is called AutoConf and it is intended for distant copying configuration files from eagle-server to the switches and routers in Cisco academy laboratory. It is handled by web pages placed on eagle-server. In this system, user can create new laboratory exercises with configuration files for network devices and then these files could be used for configurations. Informations about done configurations are saved in relation database MySQL. Network devices which will be configured by system AutoConf have to be connected with eagle-server. To setup their connection settings was created decision-making mechanism. If it detects physical connection between network device and eagle-server before network device starts, it will set network device for communication with eagle-server.

WiFi Network 802.11b and Its Simulation
Martiš, Viktor ; Očenášek, Pavel (referee) ; Šimek, Václav (advisor)
This work deals with the technological background of wireless networks and the conceptual issues of their simulation. The introductory part provides a brief review of essential facts related to wireless networks and simulation flow. Furthermore, our work will focus on one particular type of such networks, which is governed by the standard IEEE 802.11b, also recognized as WiFi network. The actual simulation will be carried out by means of "The network simulator - NS2". Its general description is included together with some practical comments on possible deployment scheme. Then, we design a simple WiFi network which will be subjected to our analysis. The underlying topology was inspired by a real network scheme where the data traffic can be constatnly monitored and evaluated. Simulation of the proposed network was successsfully performed with help of the previously mentioned NS2 simulator. Script written in TCL language, which containted network definition and necessary control commands, served as the simulation input. The final part of this work contains a general summary of individual analyses and their comparison with real-life network performance.
