Content caching at intermediate nodes is a very effective way for optimizing the operations of Content Centric Networking, so that future requests can be served without going back to the origin of the content. Several caching techniques have been proposed since the emergence of the concept. However, few of these techniques consider providing caching incentives for the nodes or quality of service guarantees for content owners. Moreover, the Content Centric Networking framework still faces challenges when implemented in the current network layering paradigm, as it requires a radical change in the TCP/IP protocol stack.
