Content-Centric Framework over the Internet Environments

In recent years, content delivery accounts for a large proportion of the Internet traffic, but end-to-end communications used in the Internet mismatch content-centric delivery and lead to considerable delivery costs and latency. Taking the advantages of content-centric networking into account, we are motivated to employ the name-based mechanism to achieve content communications in the Internet and propose a content-centric framework in the Internet environment (CCFI). CCFI proposes a mapping mechanism between a unicast address and a name so that it can employ the name-based mechanism to achieve the following two objectives: (1) forward a content request to the nearest server in a unicast way; (2) support content sharing among multiple sources. Finally, CCFI is analyzed and evaluated, and the data show that it effectively reduce the content communication costs and latency.
