Low latency internet livestreaming in named data networking

Abstract

Low Latency HTTP Live Streaming (LL-HLS) is a receiver-driven adaptive bitrate Internet streaming protocol, with five low-latency extensions added to HLS. On top of previous HLS/NDN translation work, we investigate NDNizing LL-HLS. Specifically, we design the translation of the five extensions. One lesson learned is that to achieve low-latency real-time communication in NDN is to hold requests until the response is generated at data producer, hence achieving immediate response transmission. On implementing three of the five extensions on top of the HLS/NDN translation work, low-latency livestreaming system is able to run over NDN with the average point of capture to playback latency decreased from 26.7 to 3.5 seconds.
