Abstract

Današnje višeuslužne mreže pružaju korisnicima različite vrste komunikacijskih usluga putem iste prijenosne infrastrukture (fiksne ili mobilne mreže) neovisno o prijenosnom mediju. Novija istraživanja pokazuju kako je usluga prijenosa videosadržaja strujanjem jedna od najčešće korištenih usluga. Sve je više videoportala koji objavljuju različite videosadržaje koji se često mogu gledati bez ikakve naknade. Stoga uslijed popularnosti ove usluge i njenih specifičnih zahtjeva po pitanju mrežnih preformansi, u ovom radu napravljena je analiza prometnog toka pomoću programskog alata Wireshark na temelju pristiglih paketa za vrijeme gledanja videosadržaja (uživo ili na zahtjev). Analiza služi kako bi se opisala distribucija duljine paketa koji pristižu s poslužitelja na uređaj klijenta s obzirom na vrstu sadržaja i različitih kvaliteta videosadržaja. Također se analizirao broj generiranih paketa te na taj način dodatno opisao prometni tok prilikom prijenosa videosadržaja niže i više kvalitete.

Abstract (english)

Today's multiservice networks provide users with different types of communication services through the same transport infrastructure (fixed or mobile) regardless of the media. Newer research shows that video streaming service is one of the most commonly used services. A lot of video portals publish various video content that can often be viewed without any compensation. Therefore, due to the popularity of this service and its specific requirements regarding network performance, in this paper, an analisys of trafic flow has been made using software tool Wireshark on the basis of the received packets while watching the video (live or on demand). The analysis is used to describe the distribution of packet lengths that arrive from server to client based on the content type and different video content quality. The number of generated packets was also analyzed, and in that way additionally described the traffic flow in lower and higher quality video streams.
