Networking named content

Current network use is dominated by content distribution and retrieval yet current networking protocols are designed for conversations between hosts. Accessing content and ser-vices requires mapping from the what that users care about to the network’s where. We present Content-Centric Net-working (CCN) which uses content chunks as a primitive – decoupling location from identity, security and access, and retrieving chunks of content by name. Using new approaches to routing named content, derived from IP, CCN simulta-neously achieves scalability, security and performance. We describe our implementation of the architecture’s basic fea-tures and demonstrate its performance and resilience with secure file downloads and VoIP calls.
