基于SDN的融合网络研究

With the development of network technology, a number of different network services, communications equipment continue to emerge, allowing users to exposure to a complex and diverse network environments. Therefore, how to converge a variety of Internet applications, heterogeneous network, multi-vendor network and multi-carrier network becomes particularly important. SDN as a new network architecture, letting control and forward plane separated, make application achieve the Ethernet, wireless network and even optical network resource management at different levels. The convergence network combining with SDN and network virtualization technology, is an effective way to achieve convergence networks. Based SDN, combine with the coordinate controller concept, this paper proposed a convergence network architecture based on SDN, and heterogeneous networking is tested.
