摘要
SDN(Software Defined Network)是一种创新的网络构架,其核心理念是将控制平面和数据平面分离开来,将网络的管控集中到控制层面。OpenFlow作为南向接口标准提供了控制平面和数据平面分离的可能。文章从SDN的网络构架、SDN的硬件结构和OpenFlow协议对SDN进行了基本的分析,并采用mininet平台构建基于二层学习型交换机的简单防火墙,并对其进行仿真,交换机带宽测试值最高可达到1.09Gbps。
SDN （Software Defined Network） is an innovative network architecture, the Basic principle is the sq〉aratioii of con-trol and data plane. OpenFlow, which is used as the southbound interface standard , provides a possibility to the sq〉 aration . This paper makes a basic analysis of SDN network, hardware architecture and OpenFlow protocol. Then building a simple Firewall basic L2 learning switch by Mininet platform. The maximum bandwidth of two switches is 1.09Gbps.
