Perfecting the analysis of 10Gbit/s computer network
Ťápal, Tomáš ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
The master’s thesis consists of several parts. Describes the technology 10 Gbps Ethernet. Analyzer Ixia and Endace presents, especially their use for traffic analysis and stress testing the network devices. It deals with documents RFC concerning the routers and switch testing. Thesis includes the reports of tests switches and router performed by RFC 2544 and RFC 2889 documents. Part of the thesis is dedicated to COMBO FPGA cards. Documentations to the analyzers is created in this thesis and macro is on the CD for presentation of measurement results.

Implementation and Verification of Network Interface Blocks
Matoušek, Jiří ; Kaštil, Jan (referee) ; Tobola, Jiří (advisor)
Network interface blocks are basic part of the NetCOPE platform where they help to the network application designers to deal with problems of implementing the Data Link Layer of the OSI Reference Model, especially the MAC sublayer. This thesis is focused on the design and implementation of such network interface blocks operating at speed 10 Gb/s. Designed input interface block provides checking of several parts of the Ethernet frame and allows discarding of this frame based on checking results. Output interface block supports replacing frame's Source Address by a pre-set value and provides frame's CRC computation. Both network interface blocks also include a set of frames counters. Implemented network interface blocks were tested on the COMBO card. SystemVerilog verification testbench was also designed for both network interface blocks.

Network Traffic Simulation and Generation
Matoušek, Jiří ; Kořenek, Jan (referee) ; Korček, Pavol (advisor)
Development of computer networks able to operate at the speed of 10 Gb/s imposes new requirements on newly developed network devices and also on a process of their testing. Such devices are tested by replaying synthetic or previously captured network traffic on an input link of the tested device. We must be able to perform both tasks also at full wire speed. Current testing devices are either not able to operate at the speed of 10 Gb/s or they are too expensive. Therefore, the aim of this thesis is to design and implement a hardware accelerated application able to generate and replay network traffic at the speed of 10 Gb/s. The application is accelerated in the FPGA of the COMBOv2 card and it also utilizes the NetCOPE platform. Architecture of the application is modular, which allows easy implementation of different modes of operation. The application implements both capturing and replaying network traffic at full wire speed, but traffic can be limited to a specified value of bitrate at the output. The thesis is concluded by a comparison of the implemented application and the packet generator implemented on the NetFPGA platform. According to this comparison, the implemented application is better than the NetFPGA packet generator.
