Adaptive Video Streaming over Information-Centric Networking (ICN)
Abstract
This document considers the consequences of moving the underlying
network architecture from the current Internet to an Information-
Centric Networking (ICN) architecture on video distribution. As most
of the traffic in future networks is expected to be video, we
consider how to modify the existing video streaming mechanisms.
Several important topics related to video distribution over ICN are
presented. The wide range of scenarios covered includes the
following: evolving Dynamic Adaptive Streaming over HTTP (DASH) to
work over ICN and leverage the recent ISO/IEC Moving Picture Experts
Group (MPEG) standard, layering encoding over ICN, introducing
distinct requirements for video using Peer-to-Peer (P2P) mechanisms,
adapting the Peer-to-Peer Streaming Protocol (PPSP) for ICN, creating
more stringent requirements over ICN because of delay constraints
added by Internet Protocol Television (IPTV), and managing digital
rights in ICN. Finally, in addition to considering how existing
mechanisms would be impacted by ICN, this document lists some
research issues to design ICN-specific video streaming mechanisms.
