Implementation of quality of service in a converged network
Zvolenský, Daniel ; Kovář, Petr (referee) ; Škorpil, Vladislav (advisor)
The point of this work is the creation of IP network with a proper topology, in Network Simulator version 2, where voice packet stream with recommended compresion by G.723 standard and real-time video by H.263 standard will be simulated. Theoretical part of this work consists of convergence of nets with an implementation of Quality of Services description. In practical part of this work is identification with bacis commands in program Network Simulator 2, which make possible simulation of network behaviour.

Use of reliable multicast for feedback transmission in IPTV
Sobotka, David ; Novotný, Vít (referee) ; Komosný, Dan (advisor)
This Diploma thesis is focused on a part of network communication in the system of IPTV using the protocol to provide transmission of real-time multimedia RTP, specifically using the control protocol RTCP to carry voting results. The thesis further shows variants and ways of using reliable multicast and specific multicast (SSM). The main practical goal of this thesis is the program for the simulation of carrying voting results that I have created in the C++ programming language for MS Windows platform. The result is the client program receiving an inquiry from the server and reacting by application packets of the RTCP protocol. On the other side is the server program that picks up the packets and processes them. The programs run in the console mode, thus they have no graphical user interface. A user in the server program can create any inquiry and consequently send it to the client. Furthermore, the server can possibly view the current results of voting. In the client program a user can vote and possibly send another vote that will simulate other clients.

IPTV multicast model with RTP protocol
Ležák, Aleš ; Skořepa, Michal (referee) ; Šimek, Milan (advisor)
This diploma thesis contains questions of simulation data transfer by ASM multicast. In simulation tool Opnet Modeler is proceed design of service IPTV. IPTV means television which is transfered in network by IP protocol. Data of IPTV service are sending by multicast transfer. Multicast is a technology which uses a group transfer. It is actually communication of a one source of data with many users. These users are receiving the same data. A main target of this technology is to decrement loading of source node and transference system in distribution of data towards group of users. Most often is multicast used in distribution of audiovisual data. Relation RTP/RTCP is simulated with a different numbers of users. Observed is interval of transmission of control RTCP packets. This will be reached by two methods which will be confront in the end. One is a theoretic calculation by course of a equation and second is a practical simulation in Opnet Modeler.
