Longest Prefix Match Algorithms
Sedlář, František ; Puš, Viktor (referee) ; Tobola, Jiří (advisor)
This bachelor's thesis deals with a description of basic longest prefix match (LPM) algorithms. Another algorithm - LC Trie - was added to existing implementations into the Netbench library. All the algorithms which the library includes were tested with real groups of IPv6 prefixes. They were compared on the basis of previously obtained data. Testing scripts for each of the algorithms were implemented as well as scripts for downloading groups of prefixes from significant sources on the internet.

Longest Prefix Match Algorithms
Sedlář, František ; Matoušek, Jiří (referee) ; Tobola, Jiří (advisor)
This master's thesis explains basics of the longest prefix match (LPM) problem. It analyzes and describes chosen LPM algorithms considering their speed, memory requirements and an ability to implement them in hardware. On the basis of former findings it proposes a new algorithm Generic Hash Tree Bitmap. It is much faster than many other approaches, while its memory requirements are even lower. An implementation of the proposed algorithm has become a part of the Netbench library.

Hardware Acceleration of Longest Prefix Match
Kekely, Lukáš ; Tobola, Jiří (referee) ; Kořenek, Jan (advisor)
This bachelor's thesis describes design and implementation of hardware architecture for longest prefix match in order to achieve high throughput, which is required in today's high-speed computer networks. It is focused on IPv4 as-well-as IPv6 networks. Designed hardware architecture has throughput 75 Gbps on the shortest IPv4 and IPv6 packets. Performance of designed architecture is also compared with performance of chosen algorithms, which are used in nowadays commercial devices. These algorithms are: Tree Bitmap, Shape-Shifting Trie and Binary Search on Prefixes. All algorithms were implemented in C language using multi-threaded processing.
