Distribution of Network Traffic to Multi-Core Processors
Straňák, Peter ; Kořenek, Jan (referee) ; Martínek, Tomáš (advisor)
The content of this thesis is the design and implementation description of the driver for the NetCOPE platform. This driver is required to provide rapid transfer between hardware and software as well as multi-threaded applications. Driver is designed for Linux and is modified so that it allows multiple applications simultaneous access to the card. The paper provides basic information necessary for its adaptation and implementation details of individual features. The emphasis is on high data throughput. The part of the implementation is also a modification of the user library, which cooperates with the driver.

Porting Netflow/Combo6 Probe from Linux to FreeBSD
Grešša, Pavol ; Kašpárek, Tomáš (referee) ; Čejka, Rudolf (advisor)
The thesis deals with the problem of developing device drivers for FreeBSD operation system and explains particular steps necessary for their implementation. Furthermore, it describes modularity of drivers and basic technologies used in this operation system. Its purpose is to create a device driver for the principal card Combo6x of the Liberouter project. The output of the thesis should be a complete device driver supporting DMA transfers ant interrupts.

Verification of FPGA Generic Interconnection System
Bartoš, Václav ; Martínek, Tomáš (referee) ; Puš, Viktor (advisor)
This thesis deals with design, implementation and realization of simulation verification of generic interconnection system for FPGA chips. This system is part of the NetCOPE platform developed in the Liberouter project, within which was this work done. In the beginning, an usual methods of verification in SystemVerilog language are described. Then there is a brief description of the interconnection system, aimed especially to aspects important to verification. The main part of the thesis is design of verification environment and control program of test for all three components of the tested system. It started form the earlier described principles, that are established in the Liberouter project, and it add some more features. All components of the verification environment are designed to be general and reusable, so they can be used also in other verifications related to the interconnection system. At the end of the thesis, there are discussed results of the verification, found bugs and the general advantages of simulation verifications.

Netopeer: Configuration Platform for Network Devices
Žižlavský, Marek ; Žádník, Martin (referee) ; Kořenek, Jan (advisor)
Master's thesis analyzes available network device configuration options and describes NETCONF configuration protocol and NETCONF event notifications extension in details. It describes Netopeer, open configuration platform developed on Liberouter project, and its pitote deployment as FlowMon probe remote configuration system. Newly designed Netopeer architecture, which adds support for NETCONF event notifications, was verified by reference implementation. Security of the new design and implementation was analyzed, and recommended system settings were provided. This Master's thesis is based on results of previous bachelor's thesis of author and on existing software tools developed by the Liberouter project.

Design of Network Applications for a NetCOPE Platform
Hank, Andrej ; Kořenek, Jan (referee) ; Martínek, Tomáš (advisor)
Monitoring and security in multigigabit networks with speeds 1 - 100 Gb/s needs hardware acceleration. NetCOPE platform for rapid development of network applications uses hardware acceleration card with FPGA technology by means of hardware/software codesign. Increas in performance of platform's software part is dependent of parallel processing in applications to take advantage of utilising more processor cores. This thesis analyses NetCOPE platform architecture and possibilities of parallelising classic network applications and creates models of concurrent access to data in NetCOPE platform to utilize more processor cores. These models are subsequently implemented as extensions to platform's Linux system drivers. Userspace libraries are created to provide simple interface for applications to use these new features. To achieve high throughput of this solution several optimizations are performed. Results are measured by created testing tools.
