Measurement parameters of communication via PCI Express
Dujiček, Ondřej ; Dvořák, Vojtěch (referee) ; Pristach, Marián (advisor)
This bachelor thesis deals with parameters affecting throughput of PCI Express bus and its main result is a design and implementation of a unit for measuring parameters of communication over PCI Express bus. The unit is implemented in VHDL language and its support on generating and measuring traffic at speeds up to 100 Gbps. Unit’s operation frequency, when implemented in Virtex 7 available at COMBO-100G , is 200 MHz. The implemented unit is controlled from software through MI32 interface and it is able to measure the amount of transferred packets and data in both receive and transmit directions. This information can be exported into software using MI32 interface.

DPDK for COMBO Network Cards
Vido, Matej ; Dvořák, Milan (referee) ; Viktorin, Jan (advisor)
Software framework Data Plane Development Kit provides a standard API for fast packet processing in the user space. The DPDK covers multiple devices and architectures from different vendors. The CESNET association develops the family of COMBO network cards that are able to process Ethernet traffic up to 100 Gb/s through their SZE2 interface. This thesis describes the design and implementation of the DPDK user space driver for COMBO network cards. The driver is called szedata2 and has already become a part of the DPDK mainline in the version 2.2.0 (December 2015). The thesis describes also the measurements and the accomplished results. Packets have been received and transmitted at the wirespeed of the 100 Gb/s link.

System for Protection against DoS Attacks
Šiška, Pavel ; Wrona, Jan (referee) ; Kučera, Jan (advisor)
This bachelor's thesis deals with the design and implementation of the software part of the system for protection against DoS attacks. Nowadays Denial of Service attacks are quite common and can cause significant financial damage to internet or service providers. The main goal of this thesis was to provide software, which is focused on high-speed data throughput and can provide efficient protection against these attacks in 100 Gbps networks. Key part of the system, which is being developed in cooperation with CESNET, is hardware-accelerated network interface card, which can process incoming network traffic at full wire-speed and does the operations laid down by the software part. The main task of the software is evaluation of the information about network traffic and managing actions of the hardware accelerator. The software part of the proposed system has been successfully implemented and the properties of the system have been verified in an experimental evaluation. During the work on this thesis the first implementation of the system has already been deployed in CESNET network infrastructure.
