Due to the fact that proxy-driven proxy cache management and the client-driven streaming solution of Dynamic Adaptive\r\nStreaming over HTTP (DASH) are two independent processes, some difficulties and challenges arise in media data management\r\nat the proxy cache and rate adaptation at the DASH client. This paper presents a novel client-driven joint proxy cache management\r\nandDASHrate adaptationmethod, named CLICRA,whichmoves prefetching intelligence fromthe proxy cache to the client. Based\r\non the philosophy of CLICRA, this paper proposes a rate adaptation algorithm, which selects bitrates for the next media segments\r\nto be requested by using the predicted buffered media time in the client. CLICRA is realized by conveying information on the\r\nsegments that are likely to be fetched subsequently to the proxy cache so that it can use the information for prefetching. Simulation\r\nresults show that the proposed method outperforms the conventional segment-fetch-time-based rate adaptation and the proxydriven\r\nproxy cache management significantly not only in streaming quality at the client but also in bandwidth and storage usage in\r\nproxy caches.
