To consider the different environments of the network and select the appropriate transition mechanism, this paper studies the Intranet IPv6 network integration and transition platform based on campus network. We focus on the service migration of IPv4/IPv6, and propose the design idea of network integrated service architecture. Then, from the engineering point of view, a scheme for dual protocol to find the logical layer independent and the physical layer shared is put forward, and a network service topology that supports IPv4/IPv6 user access is also proposed. In the actual deployment process, the dynamic routing, address resolution, network connectivity, are configured accordingly, and the specific scheme is tested. The experimental results show that the scheme can realize the safe and fast access of IPv4/IPv6 network resources for Intranet users, and achieve the interconnection between IPv4 and IPv6 networks.
