Analiza protokola za hitre internetne povezave na osnovi protokola uporabniškega datagrama

ROZMAN, MARJAN (author), Sedlar, Urban (mentor)

V diplomskem delu je predstavljena študija protokola za hitre internetne povezave na osnovi protokola uporabniškega datagrama (angl. Quick User Datagram Protocol Internet Connections - QUIC), ki ga je zasnoval Google za pospešitev spletnega prenosa. Najprej opisujemo delovanje in zgradbo protokola, za tem ga pa primerjamo s protokolom za krmiljenje prenosa (angl. Transmission Control Protocol – TCP). Za ocenitev njegovega vpliva na spletno učinkovitost v primerjavi s protokolom za prenos hiperteksta (angl. Hypertext Transfer Protocol – HTTP) 1.1 in 2.0 merimo čas nalaganj spletne strani v različnih pogojih. QUIC dosega primerljive ali boljše rezultate v večini primerov, razen pri izgubnem prenosu povprečne spletne strani, kjer HTTP/1.1 prenos opravi preko več vzporednih povezav. QUIC je v splošnem bolj učinkovit pri količini podatkov, ki so potrebni za prenos spletne strani, le pri prenosu ene datoteke sta obe HTTP različici boljši.

Abstract

This thesis presents the study of protocol QUIC (Quick UDP Internet Connections) that was designed by Google in order to speed up Web transport. First we describe the operation and structure of protocol, then we compare it to protocol TCP. To evaluate its impact on Web performance, we conduct a series of page load time measurements in different conditions and compare it to protocols HTTP/1.1 and HTTP/2. QUIC provides comparable or better results in most cases, except for transfer of an average Web page in a lossy network environment, where HTTP/1.1 transfers data through parallel connections. QUIC improves on amount of data needed to transfer a Web page, except for single file transfer in a lossless network environment, where both HTTP versions provide better results.
