SHINE: Secure Hybrid In Network caching Environment

Abstract

In this paper we look after the secure delivery of multimedia content across an innovative Content Delivery Network comprising both satellite and terrestrial trunks. The CDN in question leverages state-of-the-art technologies both at the edges and in the core of the integrated distribution architecture and highly relies upon in-network caching strategies in order to improve its performance. We propose an architecture envisaging a combination of multicast, simulcast and unicast communication scenarios where satellite links are exploited to support local in-network caching. We analyse integrated network deployment scenarios where the satellite acts as the interconnection link between distributed in-network caches and a terrestrial CDN and/or feeds edge-network caches at micro-centre locations.
