An Efficient Dynamic Bandwidth Reservation Method in Content-Centric Network

Currently, the Internet has been deployed widely to retrieve and distribute contents. However, since the Internet cannot efficiently deliver contents, Content Centric Network (CCN) has been proposed as new network architecture. Although communication quality control for contents delivery over CCN is also required as the same with the current Internet, the previous methods just relatively assign priority of content and cannot secure the communication quality with considering a content bit rate. In order to solve this problem, we have proposed a bandwidth reservation method of CCN. However, our previous method does not accurately calculate the bandwidth reservation. Therefore, in this paper, we propose an efficient bandwidth control method with using the DATA packet information. In evaluations, we implement the proposed method in CCNx and confirm that bandwidth of the content is guaranteed.
