Monitoring of services within active network elements by Mikrotik
Kamenář, Filip ; Slavíček, Karel (referee) ; Grenar, David (advisor)
This bachelor thesis deals with the monitoring of the VPN services on the networking elements Mikrotik. The theoretical part includes the description of RouterOS system, management options and networking devices used. The thesis consists of the description of the VPN services and analysis of PPTP, SSTP, L2TP and OpenVPN protocols, which are implemented in the practical part of this work. The theory also contains the description of monitoring devices included in the RouterOS system. In comparison, external tools are enlisted. Chosen monitoring tools are therefore implemented in the practical part of the thesis and in the monitoring script. The practical part of the bachelor thesis is focused on the establishment of VPN tunnels and its parameter measurement. The VPN clients are to be found in the Czech Republic, Ukraine and Egypt, which establishes the real conditions for network monitoring status. The final part of the work deals with the script, which is created for the automatic-monitoring of VPN service in the accessible network and sends the gathered data to the operators. The aim of the thesis is to illustrate the usage of integrated monitoring tools in the RouterOS system in the network built on the Mikrotik elements. The chosen monitoring service was the service VPN, which is being used for remote access to the local networks from distant part of the world by the corporations but also individuals. Individual monitored parameters are enlisted and compared depending on client geographic location.

Remote control of remote communication board of mobile robot
Jílek, Tomáš ; Žalud, Luděk (referee) ; Burian, František (advisor)
The thesis discusses the possible ways of remote management of devices running Mikrotik RouterOS and choosing appropriate variant for implementation of automated remote management of the device, which is part of a mobile robot. Due to the limited capabilities of embedded system, from which it is necessary to perform automated remote management of device with this operating system, it was not possible to use standardized protocols for this purpose. A substantial part of this work therefore deals with analysis and detailed documentation of proprietary protocols implemented in the MikroTik RouterOS operating system, which are suitable for implementation in an embedded system, from which it is necessary to perform automated remote management. The conclusion describes the principle of the proposed and realized implementation of proprietary protocols in C language. The described implementation is part of the library, which provides automated remote management using these protocols.

Real bandwidth devices operating on 802.11n
Vágner, Adam ; Reichert, Pavel (referee) ; Münster, Petr (advisor)
Wifi and any other recent wireless technology works in case of correct use. Simultaneously for huge density of wireless networks today is knowledge of this matters necessity. This project is generally about 802.11x standards and focused to 802.11n standard, topologies and implementations of MIMO in advance. Practical part represents measure simulations and few devices demonstrates real radio parameters. Then devices are tested to data efficiency and ping response in ideal environment and also under signal noise present environment. All measured values are compared in tables and graphs separately. Every event contains word rank.

Wireless Network
Götthans, Jakub ; Hruboš, Zdeněk (referee) ; Koch, Miloš (advisor)
The aim of this work is to design and realization of WLAN at GK SERVIS, spol. s r.o. The conception will be verified by measuring the functionality, security and reliability. The thesis is divided into theoretical, analytical and practical. The first part will discuss the theoretical problems of processing of wireless networks, in the second part analyzed the current status of LAN and WLAN in the last section has been prepared by the project and subsequently realized.

Multigateway routing system based on the Mikrotik router
Straník, Jan ; Novotný, Vít (referee) ; Jelínek, Mojmír (advisor)
This thesis deals with the routing of data traffic to multiple gateways with a network operating system MikroTik RouterOS, which has become widespread in the small firms and home users. It is aimed to describe the problem with using multiple gateways. RouterOS description itself and its core components needed to solve this issue, such as routing, packet marking and quality assuranceservices. It also deals with the description of the particular design and testing. The proposedsolution is verified on the example of a real situation. Finally, the proposed solution is compared to alternative solutions, commonly used in practice.

Application for Mikrotik RouterOS Remote Management
Doležal, Jiří ; Novotný, Tomáš (referee) ; Hájek, Josef (advisor)
This bachelor´s thesis deals with design and implementation of an application for remote management MikroTik RouterOS. Within this thesis has been created an application which allows to configure network router services. The thesis contains design and implementation of an application written in programming language C#. The application is runnable under operation systems MS Windows and Linux by using framework Mono. The application uses a user friendly graphical interface for simple management devices with MikroTik RouterOS.

Virtualization of laboratory tasks for the CISCO course
Abbasi, Farhad ; Komosný, Dan (referee) ; Kubánková, Anna (advisor)
Tato bakalářská práce se zabývá laboratorními úlohami pro novou certifikaci CISCO (CCNP ENARSI), seznámením se s tématy, výběrem nejvhodnějšího prostředí pro simulaci laboratorních úloh, vytvořením topologie pro každou laboratoř. Kromě topologie byl vytvořen konfigurační soubor (.txt) a nahrán do příslušného zařízení pro úlohy zaměřené na hledání problémů. V neposlední řadě bylo navrženo a implementováno řešení vzdáleného přístupu pro připravené laboratoře.

Virtualization on routers
Ráboňová, Jana ; Zvončák, Vojtěch (referee) ; Ilgner, Petr (advisor)
This thesis deals with router based virtualization in the field of computer networking. The main goal is to present platforms suitable for virtualization and demonstrate practical usage afterwards. There were choosen three virtualization platforms, Mikrotik MetaROUTER, KVM and LXC containers. All of them have been tested for its performance. For MetaROUTER platform has been done modifications to allow deploy the newest version of linux distribution OpenWRT. Further, there were choosen testing scenarios, for which have been shown the possible aplication of virtualization on routers.

Communications MikroTik and IPS
Golovkova, Nataliya ; Lieskovan, Tomáš (referee) ; Gerlich, Tomáš (advisor)
The bachelor thesis is is focused on network attack problems and possible protection against their consequencies. The theortecical part describes the attacks that are currently among the most widespread with focus on the attack of Denial of Services (DoS). The next part of the thesis deals with detection and prevention systems fornetwork traffic monitoring with emphasis on the Suricata system. The following part is about getting familiar with the Mikrotik devices that are used in the practical part of the thesis. The practical part aims to provide a solution to mitigate the DoS attack in the communication between Mikrotik router and Suricata system. The communication is solved in a script using the php programming language.
