- This work was published near to the REF deadline. It evaluates adaptive streaming in information-centric networks via simulation, suggesting that caching low-bitrate encodings at the edge negatively impacts quality-of-experience. The paper hypothesizes that the scale of video
services causes resource constraints to fall on the network rather than caches. The evidence derives from an optimization algorithm designed using a metric from authors' prior work, and shows performance is highest when low-bitrate content is pushed to core caches. An effective heuristic based on the optimization is able to be distributed across caches in the transmission path.
