基于SDN的网络资源虚拟化的研究与设计

With the continuous development of the Internet, types of network service and the network traffic are growing. How to ensure the transmission quality of different services has proposed a new problem to the majority of researchers. Emergence of Network virtualization makes this problem resolved, and provides convenient conditions for the study of new Internet technologies and new infrastructure reform Internet. This paper has proposed a new network resource virtualization design based on SDN, which can efficiently virtualize and allocate network resources, and also dynamically adjust resources based on the needs of the load status of the network, enabling the network resources efficiently utilization.
