Library for Fast Network Traffic Processing
Vokráčko, Lukáš ; Viktorin, Jan (referee) ; Kořenek, Jan (advisor)
This thesis is focused on time-critical operations in context of computer networks. Processed operations are packet classification, specially one-dimensional classification, longest prefix matching using binary search on prefix length and TreeBitmap, pattern matching using Aho-Corasick, regular expression matching and packet header analysis and extraction. Purpose of this work is to design API for library implementing these operations. Implementation speed of these operations is measured on Intel and ARM platforms.

Modelling and Reliability Analysis of Campus Network at the BUT
Kraus, Zdeněk ; Ryšavý, Ondřej (referee) ; Veselý, Vladimír (advisor)
This thesis informs about technologies and architecture of computer network at BUT. It describes chosen technologies and some of theirs variants. Further, it contains simulation model design of a network switch device. That is followed by the model implementation with detailed description of model parts. Then, the model is tested on a set of simulation scenarios and it is evaluated in comparison with theoretical basis and real devices. In conclusion, thesis suggests future model development and improvements.

Finding the network architecture for alarm transmission system LAN-RING
Mikšíček, Pavel ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This master’s thesis deals with a complex solution for the visualization of network topology. The first part of thesis describes the operation principle of LLDP protocol, which was chosen as a tool for retrieving informations from network traffic based on the requirement of the assignment. There is a detailed description of the LLDP protocol implementation in C language to METEL s.r.o. network products. The second part deals with possibilities of graphical interface in software SIMULand intended for managing network devices. It describes tools expansion process for the visualization of the network topology. In conclusion, the results of testing final solution are introduced.

International Alphabets in Network Traffic Monitoring
Talašová, Irena ; Vrána, Roman (referee) ; Polčák, Libor (advisor)
This work deals with the implementation of support for network identifiers containing national characters in the SProbe software project, which is designed to monitor network flows. It was necessary to test and evaluate the status of selected network applications working over SMTP, POP3, IMAP, FTP or SIP protocols. On the basis of the information obtained, an extension of the current software project SProbe was proposed - a module to support network traffic monitoring with national alphabet characters. The proposed solution was then implemented and the functionality of the entire resulting system was tested. In addition, this work proposes and implements a modification of the test environment for faster and more efficient testing of the system focusing on tests containing diacritics.
