VoIP and QoS
 Kolmačka, Jan ; Křivánek, Vítězslav (referee) ; Kovář, Petr (advisor)
The bachelor’s thesis gives the basic information about the solution of a problem with Quality of Service in sequence with the VoIP telephony. In a few last years the VoIP technologies and basically the other multimedia applications have unbelievable grow. It is caused by a big demand internet user’s for the new interactive applications offering voice transfers and streaming video. These new habits bring quite big requests on networks from the side of QoS. That is why, it was necessary to develop new methods, which reach requested parameters of QoS in single categories. The first part discuss theoretically about protocols used in the VoIP telephony. The second part presents QoS, parameters of QoS and two basic methods for guarantee QoS. In the last part of the bachelor’s thesis is theoretically described the QoS support in Wi-Fi with the main aim on new technologies QoS reservation defined in the 802.11e. The following simulations and the results of the different settings parameters QoS are made by the powerful simulating software Opnet Modeler.
