摘　　要：针对云数据中心网络存在的可扩展性和灵活性问题,提出了一种基于SDN(Software Defined Networking)的云数据中心弹性网络架构,解决目前云平台存在的网络无法弹性调度和灵活分配的问题。基于OpenDayLight设计高性能控制器集群架构和多控制器负载均衡算法,解决传统SDN架构中存在的控制器单点失效的问题,保障云数据中心中多租户的高效网络按需调度和SDN网络的可靠性。利用Mininet模拟环境验证了提出方法的有效性。In order to solve the network scalability and flexibility problems in cloud data center,this paper proposes an elastic cloud data center network architecture based on SDN(Software Defined Networking),which can solve the elastic scheduling and flexible allocation problems in the cloud platform.A high performance controller cluster and multiple controller load balancing algorithm is designed based on OpenDayLight to solve the single point of failure problems in traditional SDN architecture,and an efficient and reliable multi-tenant network is provided in the cloud data center.It uses Mininet to simulate network environment to verify the effectiveness of the proposed method.
