Routing and Caching Strategy in Information-Centric Network (ICN)
The main usage of Internet today is content distribution and retrieval. In today’s Internet, connections and data exchanging can only happen between hosts, which is also called host centric end-to-end communication. As the network users and demand of contents grows quickly, current network paradigm is getting more and more complicated and can barely meet the needs in the future. Recently, the architecture of information/content centric networking (ICN) has been proposed and is expected to replace the current communication model. As an in-network caching system, the cache management scheme is a key factor of ICN. To improve the performance of this architecture, a lot of effort has been put by many researchers into this area. In this paper, a new strategy about content caching and routing is introduced. And the results of this new scheme show that this strategy leads to a good performance, i.e., the new scheme can reach less hops, when comparing with regular LRU cache strategy. And less hops means the requested object can be found in nearer routers, the network traffic, hence, is reduced.
