VDR: A Virtual Domain-based Routing Scheme for CCN

Abstract

In this work, we propose VDR, a routing scheme based on virtual domains -- domains that are not bound to physical routers -- to exploit the benefits of aggregation and hashing while overcoming their disadvantages. VDR addresses the FIB scalability issue in CCN by facilitating aggregation without compromising on the advantages of CCN such as ease of data replication and obtaining the data from a closer source. Our preliminary evaluation shows that VDR lowers the number of FIB entries present at a router significantly without compromising much on path stretch.
