摘要: 针对当前移动核心网中业务复杂僵化的问题,提出一种基于网络功能虚拟化及软件定义网络的联动机制,通过整合控制面信息,完成复杂业务的部署以及业务链与匹配策略的动态更新,实现从逻辑规则到转发流表的物理映射,保障基于业务链的通信模式,满足服务质量的需求。实验结果表明,该联动机制可以实现高效快速的业务链部署,有效满足移动网络对灵活性及可扩展性的要求。

Abstract: Aiming at the problem that present services are complicated and rigescent in the mobile network,this paper proposes an interaction mechanism based on Network Function Virtualization(NFV) and Software Defined Network(SDN).The system can achieve the complex services’ deployment and dynamic updates of the service chain and matched policy by integrating the information get from the control plane,completing the physical mapping from logic rules to forwarding flows.It meets the demand for Quality of Service(QoS) based on the communication mode of service chain.Experimental result shows that the interaction mechanism proposed can achieve the efficient and rapid deployment of service chain which satisfies the mobile network requirements of flexibility and scalability.
