Caching and Routing Jointly in Information-Centric Networks (ICN)

Abstract

Information-Centric Networks (ICN) aim to transform the current Internet from a host-centric model to a content-centric model. The main component of ICN is the policy of caching and the routing algorithm used to respond to user requests from caches. There are downsides to caching such as redundancy of copies, or the availability of data in the cache with nodes near to the end user, and ignoring it from the routing algorithms, as well as Increase congestion on network nodes in caching policies and routing algorithms. We suggest Caching and Routing Jointly (CRJ) to combine the work of the cache management policy with the routing algorithm to achieve common goals that increase the efficiency of the work of the ICN. We perform a comprehensive simulation using Icarus simulator and using real internet topologies; Simulation results: Increased cache hit rate, reduced data replication in nearby nodes, reduced latency to process user requests, and reduced network congestion and load.
