In Information-centric Networking (ICN)' users can obtain contents from caches in ICN routers. However' how to use caches efficiently is one of challenges. One existing scheme to obtain caches uses a caching algorithm reducing cache overlaps among routers' and users can obtain caches by re- ferring to records that routers have about caches. However' this scheme has two problems. First' routers which forward Interests towards a cache are limited. Second' this scheme depends on information from an ISP on forwarding Inter- ests. In this paper' we propose Cache-aware routing scheme Referring Distance for contents managed by extended Inter- est for ICN (CaRD)' which enables all routers to obtain the closest content without information from an ISP. In CaRD' routers record hop counts to a server and a cache as passing information of contents. Routers compare these hop counts' and then send request packets towards the closest contents. Moreover' caches move by request packets' so a hop count to a cache of record needs updating. For that' CaRD extends request packets. We add two new fields to request pack- ets and change their operation. To confirm effectiveness of CaRD' we implement CaRD on a simulator' ndnSIM' and evaluate cache hit ratio' traffic and download time.
