Switches for FTTx - deployment in networks with IPTV
Horváth, Tomáš ; Reichert, Pavel (referee) ; Münster, Petr (advisor)
The aim of this paper was to acknowledge ourselves with the switches which can be used in the networks based on FTTx. The first chapter deals with the IPTV service, its advantages, disadvantages and provided services. In the following chapter, optical fibres and the possibilities of their termination are discussed - FTTH, FTTC, FTTB, FTTO, FTTP and FTTN. The next part involves the methods of broadcasting and more detailed analysis of multicast addresses including defined range and multicast distributional trees. The conclusion of the theoretical analysis of this paper is formed by the explanation of all 3 versions of the IGMP record and the division of switchers through the signals transmitted. In the practical part, the suggestion of testing these switchers is carried out. The first method represents testing through one video file in various resolutions. Another possibility of testing is based on the first method, nevertheless, with the difference that the testing is done in two streams and each one of them has a different data flow. The purpose of the last testing is to demonstrate the fact that the video flow is transmitted through multicast, not every single flow from a server to a client separately. The connection between switchers was reduced to 10 Mb/s and the chosen video file runs at these average transmission data.

Multicast Distribution Trees Modelling in OMNeT++
Malik, Adam ; Ryšavý, Ondřej (referee) ; Veselý, Vladimír (advisor)
Support of multicast routing and its implementation is one of the main goals in nowadays computer networks. Adapting new technology could be often challenging and connected with difficulties. For this reason its better to try it in some simulating enviroment and implement it only after successful results of tests and simulations. The aim of this diploma thesis is to familiarize the reader with the multicast routing, describe the possibilities of network testing in OMNeT++ and come up with new multicast routing framework for this discrete simulation tool.

Design of IP Multicast Communication Tests
Stehura, Igor ; Matoušek, Petr (referee) ; Švéda, Miroslav (advisor)
This masters thesis is about mutlicast. There are explained 2nd and 3th layers of the ISO/OSI model multicast addressing. Routers in a network use multicast routing protocols to optimally route multicast packet through the network, this is also in this project. These multicast protocols are DVMRP, protocol PIM in his two modes, PIM Sparse Mode and PIM Dense Mode. Protocol DVMRP uses protocol IGMP, which is described as well. At practical section of this masters thesis is presented connections, by which tests was executed.

Multicast in IP networks
Petrovský, Peter ; Verner, Lukáš (referee) ; Krkoš, Radko (advisor)
This semestral thesis deals with multicast communication. It explains the principle of multicast data transfer. It also deals with protocol for logging into groups and distributed multicast services. Using TFTP is implemented system for content distribution by multicast communication. It measure and compare the difference between unicast and multicast.

Multicast Simulation in OMNeT++
Mateleško, Petr ; Veselý, Vladimír (referee) ; Matoušek, Petr (advisor)
This bachelor thesis deals with the possibilities of multicast simulation in OMNeT++ simulator. It describes basic principles of the multicast data transfer and closely focuses on the IGMP protocol in all of its versions. The applied part of this thesis consists of a design and implementation of an IGMP extension module for the OMNeT++ simulator.

Architectures of Internet-Based Systems with Multicasting
Veselý, Vladimír ; Matoušek, Petr (referee) ; Švéda, Miroslav (advisor)
With rapid expansion of interest in multimedia and distributed computing applications across the Internet increases importance of optimized delivery of group traffic. According to current situation the best practice to achieve this goal is multicasting. This masters thesis summarizes multicasting methods and facts. Also it draws conclusions from practical application of presented information on commercial project.

Internet television within next generation access networks
Szymeczek, Andrzej ; Sládok, Ondřej (referee) ; Grenar, David (advisor)
The topic of the bachelor thesis is „Internet Protocol Television at the Access Networks of the New Generation“. The aim of the project is to make the network where internet television service is functional and after then to test the facilities and specifications of this network. The theoretical part of the project is focused on the basic characteristics and specifications of the internet television service. Further in the project is description of the network protocols for multimedia data transfer in real time and way of the transmission through the network. The simulation is designed in the simulation program GNS3. The simulation contains functional model of the network and because of the simulation is possible to run video streaming through the network. The transvered data and sideeffects, which have an influence on the function and quality of the stream, are analysed. Also the differences between unicast and multicast streaming are considered.

Monitoring Application for Multicast sessions
Kopecký, Martin ; Komosný, Dan (referee) ; Šimek, Milan (advisor)
This work deals with a monitoring application for multicast sessions. The general aim is to develop the application for monitoring multicast sessions from network elements of a laboratory computer network. The first part describes possibilities of monitoring computer networks in terms of monitoring techniques and protocols. The second part contains a topology of the laboratory computer network and several basic commands for setting of the multicast in Cisco IOS. The third part is devoted to the developed application for monitoring the multicast in Java language. The last part describes the testing on an actual multicast network and an example of such testing is stated there.
