The push from online video content providers to replace traditional broadcast television comes with the added expectation of comparable Quality of Experience (QoE) of video streaming. In-network caching, combined with prefetching, can be useful to improve DASH video delivery latency. In this paper, we propose an Adaptation Aware Hybrid Client-Cache (AAHCC) framework, a cache pre-fetching scheme that prefetch bitrate using an adaptation algorithm based on throughput measurements from the client and the forecasted throughput at the cache. For evaluation, we ran the experiments in a network with and without background traffic on GENI distributed testbed. Our results show that AAHCC by predicting the correct bitrate for the next segment reduces the number of unused pre-fetches and improve the byte-hit rate compare to a basic client-driven pre-fetch scheme.
