ABSTRACT
Network use has evolved to be dominated by content distribution and retrieval, while networking technology still can only speak of connections between hosts. Accessing con- tent and services requires mapping from what that users care about to the network’s where. We present Content- Centric Networking (CCN) which takes content as a primitive – decoupling location from identity, security and access, and retrieving content by name. Using new approaches to routing named content, derived heavily from IP, we can simultaneously achieve scalability, security and performance. We have implemented the basic features of our architecture and demonstrate resilience and performance with secure file downloads and VoIP calls.
INTRODUCTION
The engineering principles and architecture of today’s Internet were created in the 1960s and ’70s. The problem net- working aimed to solve was resource sharing — remotely using scarce and expensive devices like card readers or high- speed tape drives or even supercomputers. The communication model that resulted is a conversation between exactly two machines, one wishing to use the resource and one pro- viding access to it. Thus IP packets contain two identifiers (addresses), one for the source and one for the destination host, and almost all the traffic on the Internet consists of (TCP) conversations between pairs of hosts.
