A SDN-based network virtualization architecture with autonomie management

The ossified architecture and widespread application of the internet have restricted its development For overcoming the existing obstacles of network innovation and management, network virtualization and autonomic management have been proposed. However, these two attractive technologies are subjected to the headaches of updating various devices. Software-Defined Networking (SDN) separates the control plane from the data plane. Therefore, some network control and management functions could be implemented through softwares. This provides a chance for the network virtualization and autonomic management In this paper, a SDN-based network Virtualization architecture with Autonomic management (SDNVA) is proposed. The SDNVA architecture enables heterogeneous virtual networks to coexist on the same physical network, and supports hierarchical autonomic management. Moreover, we evaluate SDNVA on our testbed and find that the SDNVA architecture can perceive topology changes and isolate multiple virtual networks.
