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.

Adaptation of access networks for advanced networking technologies
Frollo, Martin ; Škorpil, Vladislav (referee) ; Novotný, Bohumil (advisor)
The bachelor thesis is focusing on the real-time services running in packet networks and problems that may arise while they are running. Specifically it is focused on the technology of VoIP service. There are many different signaling protocols to support this service. Among others, the SIP protocol is very widespread. In addition of the connection it is necessary to ensure the transmission of voice data. That is the task of the RTP protocol. This service and also others for which time is critical with increasing constraints on networks it needs to be frequently given the priority over traditional services like downloading files, and more. VoIP service has certain requirements for transmission parameters that must be followed for optimal function. They are for example, packet loss, one-way delay and delay variation. Most problematic is to ensure the optimal operation of the service on slower transmission routes. That is why it was necessary to establish mechanisms capable of real-time services to ensure sufficient network capacity to meet end user. These are, for example technologies of integrated services or differentiated services. At the present time, however, the technology of integrated services is not very widespread because of its inefficiency. On assembled telephone network made from available components in the laboratory, there are analyzed and confirmed some of the distinctive features and characteristics of the SIP protocol. Furthermore, measurements confirmed sufficient network capacity for VoIP service of the used network and parameters affecting security of the QoS have been evaluated.
