The Content Centric Networks (CCN) replaces the IP narrow waist of the Internet architecture by a content layer. When a node wants to access a piece of content, it sends an Interest packet to the network. The network then, using the name of the content for routing, forwards the Interest to one or more copies of the content object. In this paper, we present the implementation of a OpenWRT OS based testbed for CCN. We analyze the performance of Optimized Link State Routing (OLSR) protocol in an indoor scenario. We transmitted single ICMP flow over UDP. For evaluation we considered hop count, delay and jitter metrics. The experimental results show that the nodes in the testbed were communicating smoothly and we got low values of delay and jitter.
