Abstract

U radu je obrađena mogućnost pružanja interaktivnih multimedijskih usluga u javnim mrežama za prijenos podataka. Kao ključan segment arhitekture posebno je naglašena uloga IP protokola. Obrađeni su svi aspekti pružanja javnih usluga na IP infrastrukturi, kao što su izolacija, adresna separacija i garancija kvalitete usluge. Pretpostavka je da se sve vrste usluga pružaju na jedinstvenoj infrastrukturi. Navedene su sve tehnologije koje omogućuju pružateljima usluge realizaciju takvih usluga: u pristupnom dijelu mreže, koncentracijskom prstenu i jezgri.
Detaljno su obrađeni svi parametri koji utječu na percipiranu kvalitetu usluge na interaktivne usluge kao što su prijenos govora ili radiodifuzija digitalnog TV signala. Naglašeni su dijelovi arhitekture mreže u kojima je potrebno posvetiti osobitu pozornost osiguranju kvalitete usluge, kao i načini na koje je to moguće realizirati. Nadalje, posebno je izdvoje problem odabira usluge u IP mrežama, i način njegovog rješavanja na skalabilan i tehnički kvalitetan način.
U zadnjem dijelu prikazan je prijedlog konkretne realizacije infrastrukture koja omogućava pružanje usluge interaktivne televizije. Ova usluga podrazumijeva istovremenu mogućnost pristupa na usluge prijenosa TV signala, govora i podataka. Predloženi su načini realizacije arhitekture, kao i konkretne mjere koje moraju biti poduzete kako bi se usluga mogla tehnički realizirati.

Abstract (english)

This paper focuses on the possibility to provide interactive multimedia services (Interactive TV) by utilizing service provider networks. The key segment of the architecture is the utilization of IP protocol. All of the key aspects of services integration on IP networks are covered: customer isolation, address independance and QoS guarantee. Basic assumption is that all services are provided on the unified infrastructure. All of the technologies relevant to the network architecture needed to provide the services are specified: in access, edge and the core of the network. Detailed treatment is given to all of the parameters that have influence on the perceived quality of service for interactive multimedia srvices, such as voice services or TV distribution services. Parts of the architecture that are most significant for the overall quality of service are specified, as are the methods and technologies used to realize them. Furthermore, service selection problem in IP based networks is especially mentioned , and solutions for service selection are presented.
In the last part, real world architecture which enables the provider to support multimedia services is examined. Special case of the Interactive TV scenario is elaborated, which includes integration of voice, video and data services. Concrete architecture is proposed, and also the steps that need to be taken for the services to be delivered.
