On the performance of adaptive video caching over information-centric networks

The growing demand for video streaming is straining the Internet, and mandating a fundamental change in future networking paradigms. Current advancements in Information-centric Networks (ICN) promise a novel approach to intrinsically handling content dissemination, caching and retrieval. While streaming technologies are converging towards Dynamic Adaptive Streaming (DAS), in-network caching in ICN facilitates serving users with better video qualities, potentially beyond their actual bandwidth-mandated throughput. In this paper, we propose an assessment framework for adaptive video streaming to evaluate the performance of ICN caching schemes, and measure their impact on improving users' streaming experience. We present a thorough study of core performance metrics and adopt those metrics which are designed for video caching. We conduct experiments on a NS-3 based simulator, ndnSIM, and propose insights which will aid the development of future caching schemes that cater to inevitable bitrate variations.
