CP-Steering: CDN- and Protocol-Aware Content Steering Solution for HTTP Adaptive Video Streaming

Abstract

In recent years, HTTP Adaptive Streaming (HAS)-based technologies, such as Dynamic Adaptive Streaming over HTTP (DASH), have become the predominant video delivery paradigm over the Internet. HAS-based content providers frequently employ multiple Content Delivery Network (CDNs) to distribute their content to the end users. Recently, Apple and DASH-IF standardization introduced content steering technique to enable content providers to switch the content source that a player utilizes at start-up or midstream. Due to diverse adaptive video streaming demands for latency-sensitive and/or bandwidth-sensitive streams, satisfying end users with a pleasant Quality of Experience (QoE) poses a new challenge for redesigning the current content steering strategies. This paper leverages the recent popular Quick UDP Internet Connections (QUIC) transport protocol and introduces a CDN- and Protocol-aware content Steering solution for HTTP Adaptive Streaming (CP-Steering). We discuss the details of CP-Steering strategy and then give directions for future work.
