Content Centric Networking (CCN) is a new paradigm that addresses the gap between the content-centric needs of a user and the current widespread location-centric IP network architecture. In this paper, the authors propose a hybrid content centric architecture based on their pub/sub enhancement to C- CN, Content-Oriented Publish/Subscribe System (COPSS). Their hybrid architecture (hybrid-COPSS) addresses both the need for incremental deployment of CCN and also elegantly combines the functionality of content centric networks and the efficiency of IP forwarding. Their architecture integrates IP multicast to achieve forwarding efficiency by taking advantage of shortest path routing.
