软件定义网络的资源发现研究

his paper presents an improved way of resource discovery based on the features of software-defined networks. The improved source discovery takes advantage of new features of SDN to satisfies the request of network user in the layer of globale topology. It is in accord with the theory of SDN to take the function of resource discovery to the control plane to reduce the burden on datapath. In this paper, the controller adds a new resource discovery module to achieve improved resource discovery approach and complete the allocation of resources. The results of experiment show that the improved resource discovery is efficiency and lays a good foundation for resource allocation.
