Automated Inference of User Interface for NETCONF Protocol
Man, Jakub ; Orsák, Michal (referee) ; Tisovčík, Peter (advisor)
Tato práce se zaměřuje na vytvoření uživatelsky přívětivého grafického rozhraní pro zařízení komunikující protokolem NETCONF. Bylo zvoleno řešení pomocí webového rozhraní, aby bylo použití co nejjednodušší a z pohledu uživatele nevyžadovalo další instalaci. V práci bylo vytvořeno uživatelské rozhraní obsahující systém pro rozšíření a knihovnu pro operace nad protokolem NETCONF. Knihovna pro NETCONF umožňuje uživatelům připojení k zařízením, uložení informací o zařízení do databáze, připojování ke skupinám zařízení pomocí profilů a modifikace konfiugrace zařízení. Systém rozšíření umožňuje výrobcům zařízení poskytnout uživatelům grafické rozhraní, které nevyžaduje další zaškolování uživatelů, aniž by museli vyvýjet celou aplikaci.

Software Testing
Vadkerti, Miroslav ; Kořenek, Jan (referee) ; Martínek, Tomáš (advisor)
The aim of the thesis is to design a methodology for automatized source code testing for the project Liberouter. The designed methodology allows testing the compatibility and usability of the given software on a large scale of variants of supported platforms. The methodology is implemented in programming language Perl as an automatized server working with VMware Server virtualization software.

Processing Unit for Analysis and Modification of Network Traffic
Pazdera, Jan ; Kořenek, Jan (referee) ; Martínek, Tomáš (advisor)
This paper deals with the design and implementation of the Processing Unit for Analysis and Modification of Network Traffic. The proposed unit is intended to analyse an incoming network traffic and perform packet header editations to provide the proper packet delivery. The designed architecture has the following characteristics. It is based on the stream processor concept which allows to process independent stream elements (i.e. packets) in parallel. Multiply stream clients can be used to process the same stream data concurrently. The stream clients can be driven either autonomously or by program. The packets are processed according to the incoming metadata and transmited to the output. The Processing Unit has been implemented in VHDL language. The target technology is Field Programmable Gate Array (FPGA).

DMA Controller and Network Interface Card Driver for COMBO2 Platform
Kaštovský, Petr ; Kořenek, Jan (referee) ; Martínek, Tomáš (advisor)
There is a family of COMBO cards used for netork monitoring acceleration being developed on the Liberouter project, which is the CESNET's research activity. These cards are equipped with Xilinx's programmable field array. To enable usage of classic tools for network monitoring and management, not only application specific tools, it is necessary to implement network interface card on the platform, that realizes packet reception and transmission through the standard Linux kernel interface. This thesis describes the design and implementation of network interface card's key components. Those are DMA controller and Linux device driver.

Network Applications Acceleration
Štourač, Jan ; Korček, Pavol (referee) ; Puš, Viktor (advisor)
There has been developed family of cards called COMBO under the auspices of the CESNET association. These cards carry programmable field array and their purpose is intended into accelerating of net traffic. There is also a platform called NetCOPE which is based on these cards and it's purpose is to accelerate and simplify the development of network applications. This thesis contains a detailed analysis of data throughput through a whole platform and describes some possible improvements which should reflect in a better performance of the whole platform.

Adaptive Sampling of Input Packets Implemented in FlowMon Probe
Kaštovský, Petr ; Martínek, Tomáš (referee) ; Kořenek, Jan (advisor)
There is a FlowMon probe being developed in a Libeouter project that is used for passive network measurements. The probe has better stability and accuracy than sofware based solutions even under a heavy load or network attack. To guarantee a precision of results there is a need to data reduction to prevent measuring system overload. There are few kinds of data reduction. Method used in the FlowMon probe is called sampling. Adaptive sampling unit sets the sampling rate (rate of processed and discarded packets) according to actual state of measured network.

The Stateful Packet Processing in P4 Language
Kohout, Pavel ; Martínek, Tomáš (referee) ; Kořenek, Jan (advisor)
With the growing speed and complexity of computer networks, arise requirements for creating powerful devices that are capable of collecting statistics and changing their own functionality according to the demands of network administrators. These requirements can be described using specialized programming languages such as P4. In this bachelor thesis a design, implementation, testing and integration of register and counter stateful memory modules into P4 compiler system for FPGA technology was made. The created system supports the collection of statistics described in P4 language at speeds up to 100 Gbps.

Web Configuration Interface for Network Devices
Žižlavský, Marek ; Kořenek, Jan (referee) ; Martínek, Tomáš (advisor)
Main goal of this bachelor work is to design a universal configuration system for remote network device configuration based on the NETCONF protocol and to develop a web configuration interface for the FlowMon, monitoring probe. This work uses existing software tools developed by the Liberouter project. Main objective of the implementation part of this work is to develop a web configuration interface, supporting class libraries for configuration management and GUI creation in PHP. Implemented web configuration interface for the FlowMon probe is a fully-functional prototype of a configuration interface based on concepts of the universal configuration system designed in this bachelor work.
