Optimizing HTTP Adaptive Streaming using Modern Protocols

Authors: BOECKX, Bram;

Optimizing HTTP Adaptive Streaming using Modern Protocols

Abstract

De groei van internetverkeer, vooral door mediastreaming, heeft HTTP Adaptive Video Streaming tot een belangrijk deel van het netwerkverkeer gemaakt, goed voor meer dan 65% in 2022. Hoewel Video On Demand domineert, wint live streaming snel aan populariteit door de realtime interactiviteit. Het implementeren van live streaming via HAS kent echter uitdagingen, vooral op het gebied van latency, wat cruciaal is voor een optimale Quality of Experience (QoE). Deze thesis onderzoekt het potentieel van het QUIC-protocol om QoE in live videostreaming te verbeteren door latentie te verminderen en prestaties te verhogen tegenover TCP. Er wordt gekeken of QUIC beter presteert in termen van latentie, bitrate stabiliteit, en on-time weergave, en of de TCP-geoptimaliseerde ABR-logica kan worden aangepast voor QUIC. Ook wordt de impact van HTTP/3's Extensible Prioritization Scheme op QoE onderzocht. Het onderzoek omvatte updates aan het Vegvisir-framework en de dash.js-applicatie voor live streaming over HTTP/3, met aanpassingen aan de Livesim2-server. Resultaten tonen aan dat QUIC een veelbelovend alternatief is voor TCP, met extra voordelen van HTTP/3-functies zoals multiplexing. Deze bevindingen benadrukken het potentieel van QUIC en HTTP/3 om de QoE van live streaming aanzienlijk te verbeteren, vooral in scenario's met lage latentie, wat een belangrijke stap is in de evolutie van streamingprotocollen.
