An Information-Centric Design And Implementation Based On SDN

In the current network, the traffic increase very fast because of more and more services. But the transmission of the information is based entirely on information address, the content of the information is transparent to the network. There is so much information that is same transmitting in the network, resulting in a waste of bandwidth and energy. In the socioeconomic perspective, the current network structure makes low profits transmitting so mush content. So we hope the future network can provide different services to different groups and stakeholders. The future network needs a new structure to distribute information effectively.The current network is not able to complete information distribution very effectively, so lots of research institutions study to design a new structure. As the core of the network is no longer the nodes, but the information, so the future network is information-centric network. Now some research institutions have some preliminary results, such as NetInf, NDN, PSIRP, COMNET. But there does not have a unified information-centric network, so this paper will analyze some problems that still exist in the information-centric network. For the existing problems, this paper proposes an information-centric network based on SDN. This paper defines the design of the architecture, the separation of the control plane and data plane. The control plane is responsible for the distribution of the information, registration, cache management and the data plane for forwarding. In the paper, we focus on the information distribution according to the information feature and network states. In addition, the architecture also supports mobility management and multicast, which has provided a guarantee for more efficient transmission of information.After the completion of the design and implementation of the architecture, this paper evaluate of the performance of the architecture. In performance assessment, we use the theoretical analysis and also use OpenFlow and Mininet in the network to simulate including the configuration of the information distribution paths, mobility management, scalability. Analysis and simulation results show that the architecture has good performance on information transmission, mobility management, scalability.
