SDN特征剖析及典型应用介绍
Feature Analysis and Typical Application Introduction of SDN
摘要
Abstract
By comparing with policy based network control and soft switch, the technical origins of SDN are introduced. The SDN architecture, including the network programmability and network virtualization ideas, is illustrated. Its innovative features and the significance for network development are analyzed. The SDN is still lack of a clear business model and its centralized controller exists the problems in status collection and scalability. The limitations caused by the control principles of complex system are pointed out. In addition, the typical application scenarios of SDN are introduced and SDN is mainly suitable for the integrated control for IP networks, optical networks and wireless networks in local autonomous networks.关键词
