Longest Prefix Match in High-Speed Networks
Skačan, Martin ; Tobola, Jiří (referee) ; Kořenek, Jan (advisor)
This thesis deals with the Longest Prefix Matching (LPM), which is a time-critical operation in packet forwarding. To achieve 100Gbps throughput, this operation has to be implemented in hardware and a forwarding table has to fit into the on-chip memory, which is limited by its small size. Current LPM algorithms need large memory to store IPv6 forwarding tables or cannot be simply implemented in HW. Therefore we performed an analysis of available IPv6 forwarding tables and several LPM algorithms. Based on this analysis, we propose a new algorithm which is able to provide very low memory demands for IPv4/IPv6 lookups. To the best of our knowledge, the proposed algorithm has the lowest memory requirements in comparison to existing LPM algorithms. Moreover, the proposed algorithm is suitable for IP lookup in 100Gbps networks, which is shown on new pipelined hardware architecture with 140Gbps throughput.

Performance testing of networks with Mikrotik components
Kaláb, Vojtěch ; Kubánková, Anna (referee) ; Mašek, Pavel (advisor)
The goal of the thesis is to develop and describe application for Mikrotik Network stress testing. The aplication is developed in high-level scripting programming language Python. The aplication allowed us to configure and display in diagram our connected routers and network stress testing. Theoretical part is focused on Mikrotik company, their development and products. Next part is about theory of network stress testing and graph theory. The last part is about aplications development, programming language Python and used tools and libraries.

Audio signal transmission over a standard Ethernet network
Rubínek, Tomáš ; Jaššo, Kamil (referee) ; Bayer, Robert (advisor)
The work describes digital audio networks for audio signal transmission. Describes the various types of digital networks and describes them. It deals in more detail with digital networks for audio signal transmission over a standard Ethernet network and compares their possibilities and uses. It compares several types of digital networks for audio signal transmission over a standard Ethernet network: Dante, AVB, Ravenna and AES67. It also compares these networks in terms of scalability and other possible uses. The practical part of the thesis is then focused on the configuration and settings of devices in the Dante network. There are stated examples for usage of the Dante network in model situations including examples of the concrete Dante devices connected to the network. In the last part of the thesis is described the realization of Dante network in the recording and postproduction room.
