Cache-Friendly Streaming Bitrate Adaptation by Congestion Feedback in ICN
Dinh C. Nguyen, Jiong Jin, Atsushi Tagami · 2016
HTTP adaptive streaming is an attractive solution to the explosion of multimedia content consumption over the Internet, which has recently been introduced to information-centric networking in the form of DASH over CCN. In this paper, we enhance the performance of such design by taking advantage of congestion feedback available in ICN networks. By means of utility fairness optimization framework, we improve the adaptation logic in terms of fairness and stability of the multimedia bitrate delivered to content consumers. Interestingly, we find that such fairness and stability have a very positive impact on caching, making streaming adaptation highly friendly to the ubiquitous in-network caches of the ICN architectures.
