In this paper, through the demand analysis of cloud computing data center network, the typical layer 2 Technology (virtual switch technology and tunnel technology) and cloud data center cross site layer 2 interconnection technology are analyzed and discussed in detail. This paper proposes MPLS VPN technology as an important technology of cloud computing data center network second tier expansion, and discusses VPLS network architecture and working principle in detail. This paper proposes the network architecture and implementation scheme of cloud data center based on MPLS VPN, and completes the network related tests. Finally, the characteristics of the system are summarized and analyzed. In this study, MPLS VPN technology is integrated into the existing cloud computing architecture to achieve the seamless integration of cloud computing resources and lay a theoretical foundation for the connection between virtual private cloud and public cloud. The experimental results show that according to the requirements of cloud computing data center, this research realizes the dual activity of network between data centers.
