Simulation and measurement of triple play services in FTTx networks
Horváth, Tomáš ; Münster, Petr (referee) ; Šifta, Radim (advisor)
The aim of this thesis was to ascertain with the measurement methods of passive optical networks and the creation of a simulation model that corresponds to the measured network and comparison of results. The first chapter deals with Triple Play services, which are focused on different services (transmission of television signals, voice and data transmission). Each service consists of a subchapter and presents a detailed description of the parameters associated with the transmission. The second chapter of the theoretical part consists of an analysis of passive optical networks according to termination method of FTTx optical fiber. Partial part of this chapter consists of description of standard passive optical networks APON, BPON, GPON and EPON. The EPON standard is explained in detail. The theoretical part of the thesis is concluded with a description of active elements that will form the laboratory measured network. Testing of designed passive optical network is performed in the practical part of the thesis. The measurement is divided into two chapters. The first chapter consist of measuring of the „inanimate network“, as there are missing active elements in the nominated net. Network measurements were done by a direct measuring method and reflectometric method. The second chapter of the practical part consists of measuring the parameters of quality of service (QoS). This chapter is divided into subchapters, such as: the measurement using RFC 2544 standard, the measurement using ITU-T standard Y.156 (EtherSam) and bit error rate testing (BERT). The practical part ends with a designed simulation network model, which was proposed in OptSim 5.2. The aim of the simulation model was to maximally resemble a real network, due to result comparison.

Advanced Utilization of Network Analyzers
Novák, Přemek ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
This bachelor´s thesis consists of description of the laboratory network Cisco and any of its components. Furthermore, the possibility of network analysis according to the standards RFC 2544 and EtherSAM and description of the measurement using analyzer Vepal TX300, Fluke NTS II and Sunlite E1 used in lab reports. In the first task, the characteristics of network elements are analyzing. In the second task, parameters of Cisco network are examined and the third task is focused on the E1 frame.

DOCSIS Technology in Access Networks
Pirohanič, Lukáš ; Šilhavý, Pavel (referee) ; Horváth, Tomáš (advisor)
This bachelor thesis explains the design and implementation of data communication between a central unit and a cable modem. Suitable transfer medium and intermediate devices for signal forking and amplification are chosen in practical part of the work. The upstream and downstream channel transfer rates are tested using modulation techniques and also testing the DOCSIS Network for qualitative parameters and laboratory task dealing with the DOCSIS standard. The theoretical part describes DOCSIS standard, CATV network architecture and signal modulation during transmission.

Network infrastructure performance analysis
Barniak, Martin ; Verner, Lukáš (referee) ; Krkoš, Radko (advisor)
This thesis deals with analysis of network infrasctructure. It focuses on devices like a switch and router. To analyse a network we usually use resources which are divided into basic and advanced. Basic resources are the most commom like a ping, trace route, netstat, route or arp. The term advanced means network analyzers. Network analyzer is Optixia XM2. Next are described individual key parameters which are dependent on function and reliability of computer network. Thesis describe measurement methods like RFC 2544, RFC 3393 and EtherSAM. The conclusion is devoted to individual measurements and their evaluation.
