Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing:

[0027] As shown in Figure 1, it is the network connection schematic diagram of the present invention, wherein application server A 1. 4, application server A 2. 5 and user A6 are connected with VPN gateway server A2 through network A3, and application server B 1. 9, application server B 2. 10 and user B11 are connected with VPN gateway through network B8 Server B7 links to each other, there are interconnected tunnels between the VPN gateway servers and between the VPN gateway servers and the central server 1, and there are interconnected tunnels between the mobile client 12 and each VPN gateway server and the central server 1;

[0028] Each gateway server communicates with the central server to report the network information of its own agent. The central server records the entrance IP address information and network information of each gateway, and uniformly configures the v...

Abstract

The present invention discloses a method for IP address space planning exemption among VPN networks and private domain name access, belonging to the computer network technical field. The method of the present invention uses a center server for the unified allocation of IP address spaces among independent VPN networks, and then uses a domain name analysis system to realize domain name access amongnetworks. The present invention is widely applied to VPN systems and other point-to-point interconnected systems. On the basis of preserving the prior configuration among independent VPN networks, the present invention adds and removes an independent network with very low cost; by using a center management system to manage and configure the gateway information and network architecture informationof interconnected networks, the present invention improves management efficiency and simplifies configuration steps; through the mode of private domain name access, the present invention ensures thatthe access of shared resources among networks accords with common access habits, and simplifies operation.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and in particular relates to a method for exempting planning of IP address spaces between VPN networks and accessing private domain names. Background technique [0002] With the rapid development of the Internet and information technology, and the needs of enterprise informatization and network officeization, VPN (Virtual Private Network) technology has become one of the main network interconnection technologies. VPN is usually an extension of an enterprise's internal network. It is a wide area network technology that can connect remote branches, business partners, mobile office workers, etc., and provide secure end-to-end data communication. [0003] Each network interconnected by traditional VPN is independent. Since each network can allocate and use its own internal network address, it is inevitable that the IP address space used may have the problem of reuse, that is, each branch of...
