摘　　要：针对企业网络在数据通信安全性和管理便捷性两个方面的挑战,通过在网络范围内定义一种单一的细粒度的管理策略,并在其中直接执行,最终设计并部署一种新型的集中式体系架构网络。实现的集中式架构网络通过一个中心控制器与功能非常简单的基于流的以太网交换机相链接,并由中心控制器负责数据流的准入与路由管理。这种网络架构能够有效支持有线和无线两类主机节点,并与现有的主机和交换机兼容。实际的部署案例及性能测试表明,该网络架构的交换机对存储空间要求较低,同时该架构具有较好的可扩展性,并能够有效容忍链路故障。Focusing on the challenges of enterprise networks in two aspects of data communication security and management convenience,we defined a single network-wide fine-grain management policy which is directly enforced in the network,by this way we finally designed and deployed a novel centralised architecture network. The implemented centralised architecture network links with the flow-based Ethernet switches with extremely simple function through a central controller in charge of data flow ＇s admittance and routing management. This architecture can support both the wired and wireless hosts effectively,and is compatible with the existing hosts and switches as well. It is demonstrated by the practical deployment cases and the performance testing that the network architecture has loose requirement on the storage space of switches,moreover,this architecture also has good expansibility and can tolerate all kinds of link failures effectively.
