Hierarchical Cache Management for Software Defined Content Network
-
Abstract
An architecture combining Content-Centric Network and Software-Defined Network has attracted more attention gradually. This paper focuses on collecting topology information and constructing the hierarchical cache model of the network in SDCN based on POF. We discuss how to distribute cache capacity based on node value under the total storage budget for the network. A cache decision strategy based on node value -CDV and a cache replacement strategy based on content popularity-CRP are also proposed. Experimental results show that the cache performance in SDCN is improved.
