Information-Centric Network (ICN) is a new paradigm, which solve the limitations of the IP network architecture. The one of the advantage in ICN is that it reduces network traffic by using in-network caching. The caching is an important element of the ICN, because the factor that leads to efficient usage of network resources is the high hit ratio of a cache in a router. In this paper, the authors consider social influence in cache replacement policy over ICN. The social influence makes a decision based on the Social Network Service (SNS) application. This paper proposes a new cache replacement policy by social influence of user in SNS over ICN. The proposed algorithm is able to reduce network resource than existing ICN.
