Virtualization of I/O Operations in Computer Networks
 Remeš, Jan ; Martínek, Tomáš (referee) ; Matoušek, Denis (advisor)
This work deals with virtualization of computer systems and network cards in high-speed computer networks, and describes implementation of the SR-IOV virtualization technology support in the COMBO network card platform. Various approaches towards network card virtualization are compared, and the benefits of the SR-IOV technology for high performance applications are described. The work gives overview of the COMBO platform and describes design and implementation of the SR-IOV technology support for the COMBO platform. The work concludes with measurement and analysis of the implemented technology performance in virtual machines. The result of this work is the COMBO cards' support for the SR-IOV technology, which makes it possible to use them in virtual machines with wire-speed performance preserved. This allows future COMBO cards to be used as accelerators in the networks utilizing the Network Function Virtualization.

Implementation of Bloom Filters in FPGA
 Matoušek, Denis ; Kaštil, Jan (referee) ; Žádník, Martin (advisor)
The thesis deals with probabilistic data structure Bloom filter and its modifications - counting Bloom filter and multistage filter. The fundamentals of these data structures are explained and the mathematical equations describing their properties including the equation to minimize the false positive rate are shown. Appropriate hash function is chosen considering an implementation on a FPGA chip. Designs of architectures of the hash function and data structures are implemented in VHDL language and their synthesis is done. Its results are discussed considering occupied resources of a FPGA chip, a critical path and maximum frequency.

Time Synchronization in Computer Networks
 Matoušek, Denis ; Kořenek, Jan (referee) ; Martínek, Tomáš (advisor)
The master's thesis deals with design of a solution for time synchronization in computer networks that is a crucial problem of many network applications. Based on analysis of protocols for time synchronization, PTP protocol was chosen as an appropriate candidate. The thesis describes the implementation of the design for a special network interface card and demonstrates features of the solution in several tests. A part of the solution processing precise timestamps was implemented in FPGA chip on the network card while PTP messages are processed in a software application. Values of configurable parameters of the application were determined based on analysis of the network card properties and results of particular tests. It was achieved accuracy in order of tens of nanoseconds.
