SUMMARY:Dynamic Cache Partitioning for Encrypted Content Delivery
DESCRIPTION:In-network caching is an appealing solution to cope with
 the\nincreasing bandwidth demand of video\, audio and data transfer over
 the\nInternet. Nonetheless\, an increasing share of content delivery
 services\nadopt encryption through HTTPS\, which is not compatible
 with\ntraditional ISP-managed approaches like transparent and proxy
 caching.\nThis raises the need for solutions involving both Internet
 Service\nProviders (ISP) and Content Providers (CP): by design\, the
 solution\nshould preserve business-critical CP information (e.g.\,
 content\npopularity\, user preferences) on the one hand\, while allowing
 for a\ndeeper integration of caches in the ISP architecture (e.g.\, in
 5G\nfemto-cells) on the other hand. In this paper we address this issue
 by\nconsidering a content-oblivious ISP-operated cache. The ISP
 allocates\nthe cache storage to various content providers so as to maximize
 the\nbandwidth savings provided by the cache: the main novelty lies in
 the\nfact that\, to protect business-critical information\, ISPs only need
 to\nmeasure the aggregated miss rates of the individual CPs. We propose
 a\ncache allocation algorithm based on a perturbed stochastic
 subgradient\nmethod\, and prove that the algorithm converges to the
 allocation that\nmaximizes the overall cache hit rate. We use extensive
 simulations to\nvalidate the algorithm and to assess its convergence rate
 under\nstationary and non-stationary content popularities. Our results
 (i)\ntestify the feasibility of content-oblivious caches and (ii) show
 that\nthe proposed algorithm can achieve within 15% from the global
 optimum\nin our evaluation. Joint work with Gyorgy Dan and Dario Rossi\,
