As the number of branches connected to edge devices increases, the public and private network data that needs to be processed explodes, causing the edge devices to be overloaded and affecting the normal interaction of data. To solve these problems, this study analyzes the root cause of the problems and proposes a solution that integrates network equipment virtualization technology with multi-protocol label switching and border gateway protocol technology. For the feasibility verification of the solution, with the help of laboratory equipment, the environment required for the solution is built, and the deployment of the solution is completed. Then, the solution’s availability, data access control and isolation, distributed data processing and load sharing are tested, and it is compared with traditional methods in ten dimensions such as equipment redundancy, scalability, and management. The test and comparison results show that the solution can realize the distributed data processing and load sharing on edge devices, and it is superior to traditional methods as an effective VPN solution.
