摘要 为了应对网络数据的指数式增长以及满足未来网络对内容的需求,结合内容中心网络(sontent centric network,CCN)和软件定义网络(software defined network,SDN)2种未来互联网结构的优势,提出一种软件定义的内容中心网络结构(software defined content centric network,SD-CCN)。SD-CCN以SDN中分离控制平面与数据平面为核心原则,以CCN中基于内容的分发作为主要目标,其基本组成包括控制平面、控制通道、数据平面和数据通道4个部分。所有的控制决策都由控制平面发出,所有的数据操作都在数据平面完成。仿真实验结果表明,该结构相比传统的内容中心网络具有更小的网络开销。 In order to meet the exponential growth of network traffic and the content needs of future networks,we proposed the Software Defined Content Centric Network structure(SD-CCN)by combining the advantages of content centric network(CCN)and software defined network(SDN).The SD-CCN separates the control plane and data plane as SDN,and achieves information distribution based on contents.The SD-CCN consists of control plane,data plane,control channel and data channel.The control plane is responsible for making decisions and sending them to the data plane through the control channel.Data plane is responsible for different data operations.Simulation results show that SD-CCN has better performance of network overhead compared with the traditional CCN.
