Simulation of Triple Play services in XG-PON networks in NS-3
Cymorek, Patrik ; Münster, Petr (referee) ; Horváth, Tomáš (advisor)
The main goal of this paper was to familiarize ourselves with Triple Play service and to determine the possibility of simulating this service in NS-3. The first chapter of this document describes optical networks in detail. In the next chapter, we describe and analyze Triple Play service, including consideration of its advantages and disadvantages. Future development of the service is described at the end of this chapter. A short description of the Quality of Service and the BitTorrent protocol is included at the end of the theoretical section of the paper. The topology that we used for the simulation of Triple Play service in XG-PON networks is presented in the practical part of this paper. We simulated Triple Play services in the topology that we designed. The results of the simulation are presented graphically with the help of files that were recorded during the simulation. Comparison of the simulated results with real behaviour in network is included at the end of the practical section of the paper.

Analysis of Sharing Networks
Blažek, Libor ; Mašek, Pavel (referee) ; Horváth, Tomáš (advisor)
The aim of the thesis is the design and implementation of the protocol in OPNET Modeler. In this work will be developed all the elements have been used no default settings. In the first chapters, making simulation are defined packets. Another chapter consists of a block diagram of workstations, which are assigned to function blocks. The central process is created by the process model, also for the router. The individual elements are inserted into a variety of elements and subsequently used in the simulation. Connection is a new service that has been defined separately. One of the simulations will be created on a smaller scale and the other on a global scale with more features.

Design of optical access networks
Nguyen, Filip ; Horváth, Tomáš (referee) ; Münster, Petr (advisor)
The aim of this paper is to outline the problems of the design of optical access networks. In the first Rasta work is generally described problems optickcýh GPON network GEPON. The second part deals with the optical network elements, such as HDPE ducts, fiber optic cables, optical splitters and the like. The third part is devoted to legislative operation of electronic communications, especially the work is focused on the rights and obligations of providers elektronickcýh communications. It is also in this part of the studied issues of territorial management in the design of optical access networks. In the last part was designed optical network, for which the development of model documentation to obtain zoning and accompanying technical report, including drawings. The proposed network was prepared in the lab of optical networks and were made to her measurements CD, PMD, OTDR measurement and direct method.

Impact assessment of split ratios on passive optical network
Gallo, Martin ; Kočí, Lukáš (referee) ; Horváth, Tomáš (advisor)
This thesis deals with the most recent passive optical network standard NG-PON2, describes the sublayer model which includes error correction coding during propagation in optical fibres. Assesses the impact of split ratios using the simulation environment created from defined model and compares various scenarios. Discusses possible sources of errors of simulation model in compare to real deployment.

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.

Using Optical Amplifiers in NG-PON2 Networks
Hrmel, Martin ; Münster, Petr (referee) ; Horváth, Tomáš (advisor)
The aim of the thesis was to introduce the standard ITU-T G.989. Introduction deals with passive network architecture, which clarifies the basic functional elements that occur in optical networks. Been described active components and the very principle of data transfer in the distribution network. Next section is devoted to new technologies that are defined for the latest generation of passive networks NG-PON2. There have been a principle of data transmission in such networks and their advantages and disadvantages. I described the principle of data transmission in such networks and their advantages and disadvantages. The practical part deals with creating a functional network of NG-PON2 also using optical amplifiers. Another suggestion was using a digital CATV transmission of QAM modulation under optical networks on a dedicated wavelength of 1550 nm. Also simulate the coexistence of this new standard with previous PON technologies. Finally, the work consisted in implementing the Miller’s code into OptSim v5.2 environment, which compared the transmission characteristics of each line of codes with this Miller’s code. All practical simulations were designed and simulated in program OptSim v5.2.

Triple Play Services in XG-PON Network.
Horváth, T.
This paper focuses on Triple Play services in XG-PON networks and their implementation and analysis in NS-3. Nowadays, Triple Play services dominate copper/optical networks. The network simulator allowed simulation of Passive Optical Networks (PON), especially XG-PON. Each service in the XG-PON simulation is represented OnOff application with different parameters. This article describes implementation and analysis of these services in basic topology of the XG-PON network.

Network Traffic Monitoring using Long Working Analyser
Gilík, Aleš ; Horváth, Tomáš (referee) ; Oujezský, Václav (advisor)
This diploma thesis is focused on network monitoring. The theoretical part describes using of detection and prevention systems, properties of these systems, their components and detection techniques. Next part of the thesis is focused on EndaceProbe analyzer and analytic application EndaceVision. Also web services, programming language WSDL and protocol SOAP are described. The practical part is focused on creating three laboratory exercises for network monitoring and for using EndaceProbe. Components of the exercises are the traffic generator IXIA and Cisco switches with the application of remote switched port analyzer. There are also used web services EndaceProbe, programming language WSDL and SOAP protocol.

Simulation of Triple Play services in passive optical networks with OMNeT++ application
Puchrík, Matej ; Oujezský, Václav (referee) ; Horváth, Tomáš (advisor)
The thesis deals with dynamic bandwidth allocation in passive optical networks of NG- PON2 standard. The paper also describes the so-called. triple play services and the practical part is a simulation of these services in passive optical networks NG-PON2 in the simulation environment OMNeT ++. As part of this work modules for passive optical network NG-PON2 were created as an expansion of project INET. Namely ONU, OLT and splitter modules were created. The first four chapters are theoretical and descibe older standards PON networks, further NG-PON2 networks and DBA algorithm then describes triple play services and explains their current status respectively. In another part a description of the programm OMNeT++ a description of the structure of simulation models. The practical part contains a description of modules, implementation of DBA algorithm and its modification, design simulated topology and detailed description of the configuration simulation. At the end of the practical part presents the results of simulations with the corresponding explanations.
