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.

近年来，内容交付在Internet流量中占很大比例，但是Internet中使用的端到端通信与以内容为中心的交付不匹配，并导致可观的交付成本和延迟。考虑到以内容为中心的网络的优势，我们有动力采用基于名称的机制来实现Internet中的内容通信，并提出Internet环境（CCFI）中以内容为中心的框架。CCFI提出了单播地址和名称之间的映射机制，以便它可以使用基于名称的机制来实现以下两个目标：（1）以单播方式将内容请求转发到最近的服务器；（2）支持多个源之间的内容共享。最后，对CCFI进行分析和评估，
