QoS Implementation in Access Network
Adámek, David ; Molnár, Karol (referee) ; Filka, Miloslav (advisor)
This diploma thesis deals with computer networks which play a key role in present society. More and more demands are placed on these networks (especially on quality of services and throughput) because of fast-growing developement of services such as voice and video real-time transmissions. All the packets in typical Ethernet networks are equal. Therefore it is sometimes impossible for the application to maintain required throughput speed of a network. For this case it is useful to take some mechanisms into the consideration. These mechanisms (sometimes called QoS) are able to distinguish different types of transmissions and traffic, analyze them and then prioritize them according to some pre-defined set of rules. The most famous mechanisms are Integrated Services and Differentiated Services. The implementation of Differentiated Services is the goal of this thesis.

Implementation of quality of service in the control of a network element
Boháč, Martin ; Kyselák, Martin (referee) ; Škorpil, Vladislav (advisor)
The main task of the Master Thesis is introduction into problems of quality of service in converged networks especially with use of IP protocol version 6. Converged networks are able to transfer different data types - voice, data or multimedia stream. Design of active network unit is realized in Matlab Simulink. Designed model consists of simple network with some computer terminals which are connected with network element - switch. Switch model simulates real traffic of computer terminals, that are sending data to remote users. Packets in switch are sorting by data stream type and QoS. Switch is managed by neuron network. Neuron network reacts to input data and controls switch depending on type of recipient. Switch model can be used in laboratory exercising. Solving this theme needs basic skill in Simulink and theme can be done in one laboratory exercise.

Jelínek, Tomáš ; Hošek, Jiří (referee) ; Molnár, Karol (advisor)
Bachelor thesis deals with Diffserv mechanism for Quality of Service in data network and goes through several parts of structure MIB database for managing Diffserv mechanism. The first chapter is introduction. I explain SNMP protocol in the second chapter. In the third chapter I deal with Quality of Service (QoS) and in the next chapter I explain Diffserv mechanism and its architecture. In fifth chapter I present possibilities of using Policy Information Base (PIB). I show several parts of MIB database in the sixth chapter. I compare two parts of MIB database and summary whole work in the last chapter.

QoS in a computer network of VŠE
Kalina, Tomáš ; Pavlíček, Luboš (advisor) ; Beneš, Jiří (referee)
The diploma thesis is focused on analysis and deployment of Quality of Services (QoS) in a computer network of The University of Economics in Prague (VŠE). The thesis describes the main QoS technologies focusing on technology Diffserv and its deployment with using available network devices in computer network of VŠE. In thesis the needs of network services and protocols for quality of services with division into different classes of services according to priority are discussed. The thesis explains the benefits and drawbacks of deploying QoS in the environment of VŠE with regard to wired and wireless network. In the practical part recommendations are applied to the production network and subsequently the benefits of modification are evaluated.
