Caching Simulators for Content Centric Networking

Content sharing is becoming popular application of internet, yet internet design has little consideration for content sharing, so to keep up with latest trend and to efficiently use internet for content sharing, a new network concept is proposed called Content centric networking (CCN). It is one of the capable frameworks which support caching and improve fast content delivery. CCN is designed in such a way that each router in a network has storage space for caching. This paper discusses different tools capable for evaluating performance of caching techniques, different routing strategies used by the simulator for monitoring different distinctive metrics, like communication overhead, file download time, hit ratio, hit distance.
