Management of data networks based on IP protocol
Patala, Petr ; Fojtová, Lucie (referee) ; Novotný, Vít (advisor)
The objective of this master’s thesis is monitoring and management of computer networks via SNMP protocol and its practical application. The main part describes working with SNMPc program in an experimental network through implementation of its parts into the network and configuration of SNMP agents on routers, switch and end station. This thesis includes the results of traffic testing, disconnected links, effects of traffic load on QoS parameters, making longterm statistics, baselines and alarms. The thesis also includes parametres obtained with SNMP protocol from network nodes and end station.

Simulation of network element in Matlab environment
Kuchár, Peter ; Vymazal, Michal (referee) ; Vychodil, Petr (advisor)
Master’s thesis is dedicated to the issue of network element. In the first part are described technological aspects as the internal structure of network elements and control mechanisms that provide differentiaton of services and support their quality requirements. In the first chapter are listed control mechanisms from most simple like FIFO to the more sophisticated like CBWFQ. Active queue managements are not missing and they are described in the section Riadiaci člen. Significant role in the differentiation of services have processes marking and pakets classification. The second chapter is devoted most promising standard DiffServ. Contains section devoted to architecture, paket marking, code point DSCP and the final part is devoted to the types of per-hop behavior and it is expedited forwarding EF and technique assured forwarding AF. The third chapter gives an overview common models of neural networks, their properties and assess their suitability for deployment in network elements. The routher design itself and its structure in programming environment Matlab/Simulink is the subject of the fourth chapter. Except used bloks from Simulink library is described their setting and function in the wiring. Consequently results are reviewied and conclusions drawn.

Network Element with Advanced Control
Zedníček, Petr ; Kacálek, Jan (referee) ; Škorpil, Vladislav (advisor)
The diploma thesis deal with finding and testing neural networks, whose characteristics and parameters suitable for the active management of network element. Solves optimization task priority switching of data units from input to output. Work is focused largely on the use of Hopfield and Kohonen networks and their optimization. Result of this work are two models. The first theory is solved in Matlab, where each comparing the theoretical results of neural networks. The second model is a realistic model of the active element designed in Simulink

Simulating the control of a network element with neural network
Šilhan, Petr ; Kacálek, Jan (referee) ; Škorpil, Vladislav (advisor)
The thesis deals with the use of neuronal networks for the control of telecommunication network elements. The aim of the thesis is to create a simulation model of network element with switching array with central memory, in which the optimization control switching array is solved by means of the Hopfield neural network. All source code is created in integrated environment MATLAB with the use of Neural Network Toolbox.
