Introduction to content centric network architectures replacing traditional location centric network

Nowadays, internet has became most important infrastructure used by the population over the 38.8 billion. The internet is the inseparable from our daily life. The internet based on such location centric communication, however, may induces high risk of network congestion and network service down due to network traffic dominated by contents delivery and multimedia applications. Then, the concept of content centric network (CCN) or information centric network (ICN) has been attracting the attention to resolve the problems under the location based network architecture. This paper explains the overview of the overview of network architectures based on CCN concept in order to help researchers developing well suited next-generation CCN-based network architectures.
