Abstract

Tema ovog završnog rada bila je analiza funkcionalnosti čvora zaduženog za upravljanje pozivom u višemedijskom sustavu. Čvor CSCF u promatranom rješenju ostvaren je tehnologijom virtualizacije. Platforma kojom se upravlja resursima virtualnog višemedijskog sustava, u ovom radu je Openstack.
CSCF čvor sastoji se od više logičkih komponenti koje međudjelovanjem ostvaruju usluge definirane na aplikacijskom sloju. Slučajevi uporabe ostvareni u laboratorijskom okruženju predočeni su alatom Wireshark. Uspješni osnovni poziv, te poziv izvan pozivateljeve SIP domene analizirani su na razini poslanih i primljenih paketa s ciljem uvida u ulogu CSCF čvora za upravljanje poziva.
Ovaj rad sadrži opis arhitekture virtualiziranog IMSa, s naglaskom na arhitekturu CSCF čvora, slike alatom Wireshark snimljenih slučajeva uporabe, te sekvencijske dijagrame osnovnog poziva i poziva izvan pozivateljeve SIP domene.

Abstract (english)

The subject of this thesis was the analysis of the functionality of the node in charge of the Call Session Control Function within the multimedia system. In the observed solution, the CSCF node is realized via virtualizing technology. Platform used for coordination of virtual multimedia system’s resources is, in this thesis, Openstack.
The CSCF node contains multiple logical components which realize the services defined on the application layer through interaction. Use cases achieved in a laboratory environment are presented with the help of the Wireshark tool. Successful basic call and call outside the originating user’s SIP domain are analysed on a level of sent and received packets with the goal of understanding the role of the CSCF node for calls management.
This thesis contains a description of virtualized IMS architecture, focusing on the CSCF node’s architecture, screenshots of use cases captured by the Wireshark tool and the sequential diagrams of the basic call and the call outside of the originating user’s SIP domain.
