内容中心网络（CCN）通过内容层取代了互联网架构的IP窄腰。当节点想要访问一段内容时，它会向网络发送一个Interest数据包。然后，网络使用内容的名称进行路由，将兴趣转发到内容对象的一个或多个副本。在本文中，我们提出了一个基于OpenWRT操作系统的CCN测试床的实现。分析了室内环境下优化链路状态路由协议（OLSR）的性能.我们在UDP上传输单个数据流。为了评估，我们考虑了跳数，延迟和抖动指标。实验结果表明，测试床中的节点通信顺畅，延迟和抖动值较低。
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.
