Optimization of network position prediction
 Pospíšil, Petr ; Pfeifer, Václav (referee) ; Burget, Radim (advisor)
This work is about position prediction in network, it is focused to find Landmark closest to the Host in the network (with lowest distance vector). The algorithm is based on GNP system. In terms of GNP system simulation was selected method for mathematical part of position prediction. The method was Simplex Downhill. The designed algorithm was implemented in Java. In the first step chose Host continent by meassuring the distance vector. In next step is selected nearest part in the continent. In conclusion estimate Host its position and then closest Landmark. Results from this work is important for designing TTP protocol. The verdict is that the GNP can be used for TTP, but Landmarks must be located in uniform density.

VoIP- IP network voice communication
 BERAN, Václav
The possibility for using the VoIP technology as an alternative solution for the te-lephone system is very attractive. The main reason is the widely expanded computer sites and also their higher effectiveness. The main goal of the work is to describe the VoIP technology and create the first publication in Czech republic which deals with this theme in details. First of all I concentrate on the explanation of the basic words, conceptions and principles necessary to fully understand the whole field. The main scope of the work is VoIP technology which is described in third chapter. There are described also the methods of voice coding, signalling protocols (SIP, H.323, MGCP, IAX) and issues related with QoS. The work also covers the Skype program with descriptions of it's principles, installation and control.
