An Information-Centric Content Delivery Network Excluding Redundant Surrogate Duplications

We pursue herein the establishment of an advanced and feasible Content Delivery Network (CDN) system by exploiting a simple Information-Centric Network (ICN) capability on the IP network, introducing a Breadcrumbs-based in-network guidance framework in addition to user-side caches. Through caching property analyses, we first present an interesting and beneficial feature by cooperation as follows: each popular content is automatically (without explicit control) cached on a designated surrogate server without duplication. Moreover, we propose a new cooperation method between CDN and Breadcrumbs, which enhances the abovementioned feature and consequently reduces the workload of origin servers and cache miss ratio by effectively using the cache capacity with a smaller processing overhead.
