ABNO-driven content distribution in the telecom cloud

As current traffic growth is expected to strain capacity of today¿s metro network, novel content distribution architectures where contents are placed closer to the users are being investigated. In that regard, telecom operators can deploy datacenters (DCs) in metro areas, thus reducing the impact of...

CP¿s data is replicated in the core DCs through the CP-VNTs, while metro-to-core (M2C) anycast connections are established periodically for content synchronization.
