Designing Content Placement of CDN for Improving Aggregation Effect of ICN FIBs

Information-centric networking (ICN) has attracted wide attention as a new network architecture which can efficiently deliver digital content and Internet of Things (IoT) data. However, prefix aggregation of FIB (forwarding information base) of ICN routers is difficult because the organization names are independent of location. In this paper, we propose to use the CDN (content delivery network) as a method of allocating originals of content at routers to effectively reduce the size of FIBs of ICN routers. Using the measured data of web-content location, we evaluate the proposed algorithm of allocating web content at routers and show that the proposed method can reduce the size of FIBs by about 45% on average.
