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.

Optimization of digital switching fields
Mikéska, Marek ; Šilhavý, Pavel (referee) ; Kapoun, Vladimír (advisor)
The diploma thesis is focused on the features description of electronics switches for digital switching arrays and on the design of program for optimal calculation of switching points and the figure of switches in digital switching arrays investigation. The electronics switches types, used for time circuit separation, are described in the preamble. These switches are the base of digital switching arrays and in principal two types are defined: the switch S and switch T. The switch S allows the interconnection only of the same channel intervals from incoming circuit with random outgoing circuit. The switch S is being used in multistage switching arrays in combination with the switches T because it can not be used separately. The switch T allows exchanging the time position of incoming circuit to different time position of outgoing circuit depending on connection needs. The time switch can substitute the space switch under specific work conditions. In practice, the time switch with controlled reading and writing is used. The following part of diploma thesis is focused on the designs and calculations of optimal switching points of digital switching array which is the executive unit of switching systems. These systems directly interconnect the signals from digital multiplexes and make the basic assumptions for telecommunication networks integration. The digital switching array means the equipment which is able to connect the channels of digital multiplexes carrying the information in encoding form. The multiplexes are the most often with pulse coded modulation or adaptive delta modulation. The digital switching arrays are divided into the time and space one. The switching arrays of digital switching systems can be made by time switching array T whose realization is limited to specific capacity or by the connection of multistage arrays. Single stages sequenced one behind each other are made by the switches T and S. The space array S does not allow making the digital switching array of switching centre. The program which determines possible proposals of switching arrays from defined figure of inputs and calculates the optimal figure of switching points and switches is a part of diploma thesis.
