Content distribution systems, such as on-demand video services [6], file-sharing networks [8,1], and content clouds [2], provide ubiquitous data access and data sharing for large numbers of end-users. To efficiently provide content access across geographic locations, content storage nodes with limited capacity are conventionally organized in a multi-layer architecture to facilitate vertical as well...
Content cloud systems, e.g. CloudFront [1] and CloudBurst [2], in which content items are retrieved by end-users from the edge nodes of the cloud, are becoming increasingly popular. The retrieval latency in content clouds depends on content availability in the edge nodes, which in turn depends on the caching policy at the edge nodes. In case of local content unavailability (i.e., a cache miss), edge...
In this paper we study the content retrieval delay in a hybrid content distribution system, e.g., emerging content clouds [1], where a requested content item can be vertically retrieved from the central server and horizontally retrieved from network nodes. The content retrieval delay depends on the load intensities of the retrieval sources, which have asymmetric system properties such as bandwidth...
