Accounting and Inspecting IP Telephony Traffic
Sivák, Vladimír ; Ryšavý, Ondřej (referee) ; Matoušek, Petr (advisor)
This thesis describes architecture of IP telephony networks based on signaling protocol SIP and transport protocol RTP. Also tools used for analyzing VoIP traffic are described. Main objective is to design and implement a system for the detection of calls and extraction of voice payloads from the captured packets. The system first recognizes the signaling messages of SIP protocol. These messages are analyzed afterwards. Output statistics are generated based on gathered data. Voice data will be stored in form, which is suitable for further processing.

Modelling Cisco Router in Simulation Tool OMNeT++
Sivák, Vladimír ; Ryšavý, Ondřej (referee) ; Matoušek, Petr (advisor)
This bachelor's thesis describes simulation of computer networks using open source simulator OMNeT++ including the INET Framework extension. According to real behaviour of Cisco routers, we implemented a new modul for the INET Framework extension. Casy study compares behaviour of real network with simulation of the same network in OMNeT++ using the implemented modul.
