CCN protocol: Relieve telecommunications backhaul congestion


PARC has developed a communications protocol complementing existing IP infrastructure to dramatically reduce backhaul congestion on telecommunications networks. Content-Centric Networking (CCN) uses a unique architecture that caches content at the packet level, at every node, as part of the network itself. This provides superior performance to application layer Content Distribution Networks by providing very fine-grained responsiveness to changes in both location and traffic mix. CCN is available as part of a network layer, not the application. Wherever IP is extended to the edge in Long Term Evolution networks, CCN can significantly reduce backhaul capital expenses, with the lowest cost operating expenses, since CCN protocol can be deployed as an overlay on IP.
