摘　　要：SDN北向接口是通过控制器向上层业务应用开放的接口,其目标是使得业务应用能够便利地调用底层网络资源和能力。文章首先介绍SDN北向接口的功能、分类及实现案例;进而以云计算资源管理平台为例分析SDN应用;最后在OpenStack开源框架下提出虚拟机迁移网络策略同步跟随场景的实现方案。Network applications and services can invoke underlying network resource and capability efficiently vianorthbound, which is exposed by SDN controller. First of all, this paper introduces the function, classification and use caseof SDN northbound. Furthermore, cloud computing resource management platform is analyzed as typical SDN application.Finally, the concrete implementation solution on virtual machine migration with synchronized network policies is proposedbased on OpenStack open source framework and its SDN Neutron plugin.
