Networking communication system and method based on multi-centralized VPN server

The invention belongs to the field of mobile communication, and provides a networking communication system and method based on a multi-centralized VPN (Virtual Private Network) server, which introduces a VPN management server and a UDP (User Datagram Protocol) shunting server, can dynamically add and manage multiple VPN servers, and solves the problem that the VPN server is difficult to expand. And nearby access of the client is supported, and the problem of long time delay of mutual access of the client is solved. Client list subscription synchronization between the VPN servers is supported, and the problem that disaster recovery transfer of the VPN servers is difficult is solved. The public network address information after the NAT of the client side is regularly added to the IP header reserved field, the possibility is provided for mutual P2P access between the client sides, and the problem that the server bandwidth occupation is high is solved. 本发明属于移动通信领域，提供了一种基于多中心化VPN服务器的组网通信系统及方法，本发明引入VPN管理服务器和UDP分流服务
