Network services in IMS
Mikulec, Matěj ; Mácha, Tomáš (referee) ; Nagy, Ľuboš (advisor)
This thesis is focused on services that can be used in the architecture IP Multimedia Subsytem. The first chapter describes the main entities in the IMS architecture. The second chapter is focused on services - Presence, Instant Messaging, Push to Talk over Cellular and IPTV. For each service is described architecture and basic signaling. The third chapter describes the various protocols used in IMS, protocol SIP is described in more details. The fourth chapter contains a description of the application environment SDS Ericsson in which was implemented practical part. The fifth and final chapter deals with the IPTV service in SDS and SIP communications with IMS core. Traffic reports are analyzed in each case the client communication with IMS core with integrated tracking of messages passing through the CSCF, HSS and DNS in program SDS. Important findings of the work are summarized in the conclusion.

POF - polymer optical fibres
Mikulec, Matěj ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
This work focuses on polymer optical fiber (POF). It describes basic properties of polymer optical fibers, materials for production and methods of manufacturing processes. In following chapters are given individual fibers that vary different refractive indexes and diameter of fiber. Also there are analyse connectors which are used for joining. As very suitable solution for home installation seems to be using the system Optolock without connectors. In the work is also written several areas where it is possible to use the POF. It can break through in automotive industry, home networks or as a sensor. The practical part contains measuring polygon draft and FTTH proposal using POF for distribution system in the house, where P2P topology is choosen. It´s also made a proposal for distribution of POF in the apartment. For installation in the apartment prices of network components are compared between POF distribution and UTP cat.6 cabling. UTP cat.6 is in this comparison many times more cheaply. Final chapter evaluate demands on work with POF fibers. Describes preparation of fiber before communication and creation of small experimental network. Important findings of the work are summarized in the conclusion.
