A Method for Improving Cache Hit Ratio by Virtual Capacity Multiplication

Abstract

Recently, ICN (Information Centric Networking) attracts many number of network researchers as the key technology for supporting future networking. The future network needs to deliver the multimedia contents consist of large bits size over the network in the request from a bunch of consumer. As the solution for such contents delivery, ICN propose to implement in-network cache for reducing amount of traffic and response time induced by contents request and contents delivery. However, due to the capacity of contents router’s limitation, cache hit ratio of the ICN degrades when the number of requests from users is increased. Hence, in this paper, we propose a method to increase cache hit ratio on ICN against increasing contents requests. Our method increases cache hit ratio by virtually increasing capacity of contents routers by cooperation among the routers.
