软件定义网络(SDN)为未来网络业务的管理要求提供了一种新的解决方案。以动态服务功能链作为服务功能编排模式、以高级网络编程语言作为服务功能部署工具,并结合虚拟网络映射设计了业务到策略、从控制器到网络节点的部署方案。基于SDN三层结构,提出动态策略管理系统。动态策略管理系统可以根据反馈的网络状态信息调整网络策略,并对同一节点上的网络策略进行冲突检测,根据不同的冲突类型选择组合方式,有效避免了网络策略冲突,实现网络服务的自适应部署。最后,通过实验验证了动态策略管理系统从业务到策略的完整部署过程。
Software defined networking(SDN)provides a new solution for management requirements of the future network. Based on dynamic service function chain as the creation model of service function
advanced network programming language as a service deployment tools
and combined with virtual network mapping theory
a deployment scheme which could take services to policies
and take controllers to network nodes was designed. Based on the three-layer structure of the SDN
a dynamic policy management system was proposed. It can implement self-adaption deployment of network service
which based on the feedback information of the network state. Besides
it can detect network policy conflicts on the network note and choose different ways of combination to avoid policy conflicts. Finally
the complete deployment process of the dynamic policy management system was verified through some experiments.
