dc.description.abstractA hierarchical cache architecture for the telecom cloud is investigated. Intermediate cache (IC) nodes, placed in geographically distributed datacenters, are interconnected through permanent “per content provider” (CP) virtual network topologies (CP-VNT), whilst leaf cache (LC) nodes are placed close to users. CP's video contents are replicated in the IC nodes through the CP-VNTs, whilst LC-to-IC anycast connections are established periodically for content synchronization. Topology creation and anycast provisioning problems are first formally stated and heuristic algorithms are proposed. Exhaustive simulation results show significant improvements in supported traffic. Algorithms are then experimentally validated within an implementation of the Applications-based Network Operations architecture.
