Cluster-based Cooperative Caching and Forwarding in CCN

Catching is one of the important issues in Content Centric Network (CCN). The default CCN caching scheme mainly focus for redundancy. However, the usage of the cache is inefficient because, CCN Routers store the whole Data in their Interest forwarding paths and multiple duplicated data are in the network. We would like to reduce cache storage usage and forward Interest message efficiently. In this paper, we propose a cluster based chunks de-duplication and forwarding mechanisms within an Autonomous System (AS). A content data is divided and parts of data are cooperatively stored in multiple routers. Thus, cluster based cooperative caching and forwarding mechanism can significantly reduce the Content storage size on each router as well as forwarding Interest traffic in the network. 1
