CCN is communication architecture that takes content as a primitive
and retrieves content by name
not by host IP again.It builds on publish/subscribe and network-embedded caching with bandwidth-storage tradeoff.Since it is a clean-slate design
there are many issues to be explored.The concepts
characteristics
network model and recent advances of CCN were introduced.The challenges and some key issues CCN faced were also emphasized.In order to demonstrate the feasibility and implementations
two CCN system samples were also presented.
