In recent years, many studies have investigated networksthatmainly focus on transmitting and receiving content (i.e.,information-centric networking) rather than on hosts thattransmit and receive contents (host-centric networking),such as a conventional TCP/IP network [1, 2]. Content-Centric Networking (CCN) [1] is one of the promising architecturesfor realizing information-centric networking.Because of content caching at routers and existence ofmultiple repositories storing content replicas, content deliveryin CCN is classified as an anycast (any-to-one) communicationsrather than a unicast (one-to-one) communication.
