Abstract

WebRTC je skup standarda i protokola koji omogućuju audiovizualnu komunikaciju u Web pregledniku, prijenos podataka i mnogo više putem peer-to-peer veze. Opisana je pozadina takve komunikacije, osnovne arhitekture, mogućnosti WebRTC-a, te su predstavljene postojeće aplikacije koje ovu novu tehnologiju koriste.
Objašnjeni su osnovni koncepti i metode kvalitete usluge (engl. Quality of Service, QoS) i iskustvene kvalitete (engl. Quality of Experience, QoE), kao i testovi koji se koriste za ocjenjivanje iskustvene kvalitete audiovizualnih komunikacijskih usluga.
Pomoću eksperimenta, prikupljeni su rezultati od 20 ispitanika koji su komunicirali s vođom eksperimenta u 9 različitih scenarija ovisnih o vrijednostima manipuliranih mrežnih parametara. Rezultati su objašnjeni i raspravljeni.

Abstract (english)

WebRTC is a group of standards and protocols that enable audiovisual communication in the browser, data transfer and much more in a peer-to-peer fashion. The background of such communication, the main architectures and models, capabilities of WebRTC and existing applications that are using this new technology were described.
The main concepts and methods of Quality of Service (QoS) and Quality of Experience (QoE) were explained as well as the tests that are used in evaluating QoE of audiovisual communications.
In an experiment, results were collected from 20 subjects communicating with experiment leader in 9 different scenarios depending on the value of manipulated network parameters. The results were explained and discussed.
