Advanced features of traffic shaping for 802.3 and 802.11 networks under OS Linux
Pánek, Michal ; Endrle, Pavel (referee) ; Szőcs, Juraj (advisor)
This bachelor work deals with possibilities of traffic shaping and control in OS Linux. First part of the work examines indiviual tools needed for working with data stream. The second part consideres methods intended for traffic shaping. From these methods intended for use in standarts 802.3 and 802.11 were selected and described. The second part of paper focused on Hierarchical Token Bucket and Class-based queueing method. The third part is the practical application of methods on the hardware, the measurement of the individual standards and processing into charts.

Establishment of the Linux internet gateway using advanced filtering
Matocha, Tomáš ; Pust, Radim (referee) ; Jelínek, Mojmír (advisor)
The thesis Establishment of the Linux internet gateway using advanced filtering focuses on~the installation of~the Linux operating system on~the older computers, that functions as a gateway to connect clients in the internal network to the Internet. The thesis describes creation an advanced filter with using iptables. Shows some types of security against attacks from the Internet. The other chapters are discussed, advanced traffic control mechanism (such as a TC and a qdisc). The system queue, it is highly beneficial where it is necessary to hierarchically divide traffic between users. It describes types of queue and assembled configurations for clients in the internal network. Next chapter describes the DNS server caching-only type and application denyhosts, which increases the overall security system. Have your own DNS server is certified, especially if we want to reduce the data traffic. Last chapter describes the RADIUS server and its implementation using Apache and MySQL database. Furthermore, the configuration options are described and the examples of the particular configurations are provided. Finally, it presented a system for authentication through the RADIUS server. The thesis seeks to provide a~complex view of security and filtering.
