Abstract: 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.
