Utilization of Software Exchange in Laboratory Education
Komárek, Milan ; Endrle, Pavel (referee) ; Škorpil, Vladislav (advisor)
The main aim of this bachelor thesis is the use of a switchboard in laboratory exercises. The first section describes the SIP signalling protocol, its components, addressing and messages. In the second part there are designed three laboratory tasks. The first laboratory task is focused on connecting 3CX switchboard and Cisco router using a SIP Trunk. This describes the configuration of the switchboard, Cisco router and IP phones. The second laboratory task verifies the function of data transcoding in a 3CX switchboard. That includes an analysis of voice connection of participants working with a different codec. The third laboratory task tests specific functions provided by the 3CX switchboard.

IMS technology testing
Kuběna, Pavel ; Martinásek, Zdeněk (referee) ; Mácha, Tomáš (advisor)
This thesis is about the IMS technology, which is a standard defining the architecture for providing multimedia services. The theoretical part is a general description of the technology, architecture, a brief description of segments and used protocols. The practical part is a description of the environment of Open IMS Core and testing network designed according to theoretical knowledge. This is essentially a description and analysis of the registration process, voice transmission(it means a call between two users), text relay and video. A laboratory task was created on the basis of obtained knowledge.

IMS security solutions
Porubský, Tomáš ; Rášo, Ondřej (referee) ; Mácha, Tomáš (advisor)
In the first part of my master's thesis the network architecture of IMS (IP Multimedia Subsystem) is presented. The database of subscribers HSS (Home Subscriber Server) and SLF (Subscription Locator Function), as well as a SIP CSCF servers (Call Session Control Functions) process a SIP signalization and an AS application server performing services, etc. I focus on the registration of subscribers in the IMS network with a list of transmitted messages and description of each interface that is used in this network. The most important interfaces, which I described here, are Gm, Mw, Cx, Dx and Sh. Then I focused on security in IMS problems, which are divided into categories of access security and network security. After that is the implementation of IMS network in an open source Open IMS Core System considered under the Linux operating system. Here is the problem description from the actual system installation, through the configuration of all necessary elements of the network to the communication party itself. The communication analysis in the initial registration process and in subsequent communications is described. Finally I created laboratory exercises with a focus on the Open IMS Core System, where students learn about architecture and principle of networks based on IMS technology operation, with individual elements necessary for the operation of the network and their configuration. Students also test simple captured traffic analysis.
