Research on Cache Placement Strategy for CCN in Future Network

In order to overcome the well known deficiencies of the current Internet,the future network is becoming the research hotsopts,and great expectations are held on the Content-Centric Network( CCN). A distributed cache strategy which allows the network node to store the content is used in CCN. The cache placement of CCN is a popular issue now. With the analysis of some common cache placement strategies,propose a dynamic cache placement strategy based on the popularity of the content and potential demands. Content will be cached on some nodes. Then,simulation experiments are conducted on ccn Sim. The experimental results showthe cache efficiency will be obviously improved.
