Analysis of WiFi Traffic at the BUT
Lacina, Vojtěch ; Matoušek, Petr (referee) ; Čejka, Rudolf (advisor)
This work inquires into problem of current wifi traffic on VUT. The traffic has been captured with tcpdump program, anonymized and analyzed in process of creating this work. All this in order to get insight into it's nature. Resulting informations imply the need for traffic shaping which is described later in work. This work tries to determine most fitting means of traffic shaping which would result in improved quality of connection for interactive applications as well as greater satisfaction of provider (VUT) and users.

Traffic Shaping in High Speed Networks in DPDK
Doležal, Pavel ; Fukač, Tomáš (referee) ; Vrána, Roman (advisor)
This bachelor thesis is focused on traffic shaping in high speed networks. It presents framework DPDK, which can be used for fast packet processing. General traffic shaping mechanisms are described as well as traffic shaping in Linux using program tc. It also introduces a design and implementation of traffic shaper using DPDK framework for networks with 10 Gbps bandwidth. The traffic shaper uses a complex mechanism of hierarchical token bucket. The system was tested using high speed traffic generator Spirent.

PC as a Border Router of an Internet Service Provider
Nowak, Michal ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This Bachelor Thesis tries to investigate structure of a network of medium size Internet Service Provider in Rousínov and surroundings, as well as tries to study demands of ISP that belongs to router's functionality. Thesis discuss mainly chosen distribution of the Linux operating system and used system services with regard to computer and system services performance and stability. Anyway an absolute majority of bandwidth will belong to IPv4 traffic, Router is IPv6 capable thought Tunnel Broker. Another components of thesis are basic authentication, blocking of unknown clients, traffic shaping and basics of theory about WAN interfaces bonding.

Network Capacity Optimization on UNIX
Pelikán, Martin ; Galamboš, Leo (advisor) ; Steinhauser, Antonín (referee)
Title: Optimizing the utilization of networks' capacity on unix-like systems Author: Martin Pelikán Department: Department of Distributed and Dependable Systems Supervisor: RNDr. Leo Galamboš, Ph. D., Department of Distributed and De- pendable Systems Abstract: Modern unix-like systems contain very powerful network stacks with configuration options often beyond operators' understanding. A comparison of available algorithms, documentation and visualization of certain components help their understanding, leading to better configuration choices. By explaining the network stack from the drivers up to the network layer will exhibit problems with timekeeping, burst traffic processing or queue management with regard to classification, scheduling or traffic regulation options in Linux or OpenBSD. The thesis works as an overview of implemented algorithms and updated documen- tation of Linux's actions and filters, while the implementation introduces a new portable tool to visualize existing configuration on remote machines without the need of modifying them. Keywords: network internals, traffic shaping, traffic classification, queue ma- nagement 1
