[0024] In this scheme, a hierarchical virtual private network is required, that is, it divides the VPN into a sub-VPN and a parent VPN. The hierarchical relationship between the sub-VPN and the parent VPN is fixed, and the parent VPN is responsible for the services of its sub-VPNs. and connection, which does not solve the problem of limited bandwidth on a single VPN instance

Embodiment 1
[0078] like figure 2 As shown, a communication method based on an OpenVPN cluster, the method involves a VPN cluster, a gateway, a terminal device connected to the gateway, a client, and one or more gateways are connected to each VPN instance that is communicatively connected to the gateway, and the One or more terminal devices are connected to the gateway; each VPN instance that is preferably connected to the client for communication is connected to a client; in this way, even if there are multiple clients involved in multiple services, they do not need to be connected to the same VPN instance. Overcome the serious bandwidth limitation problem caused by multiple clients connecting to the same VPN instance in the traditional technology.
[0079] The VPN cluster is created by a gateway management platform, the VPN cluster includes multiple VPN instances, some VPN instances are connected to the gateway of the peripheral device, and some VPN instances are connected to the client...
Embodiment 2
[0216] refer to Figure 4 , an OpenVPN cluster-based system, including a VPN cluster, a gateway 2, a terminal device 1 connected to the gateway 2, a client 4, and a gateway management platform 5;
[0217] The gateway management platform 5 includes the following modules:
[0218] VPN instance 3 generation module: used to create multiple VPN instances 3 on one or more hosts;
[0219] Routing table generation module: create a routing table and distribute the routing table to the host;
[0220] Distribute the routing table containing the routing paths between the client 4 and the corresponding VPN instance 3 to the corresponding client 4;
[0221] Distribute the routing table containing the routing paths between the gateway 2 and the corresponding VPN instance 3 to the corresponding gateway 2;
[0222]Routing rule generation module: for setting routing rules and distributing routing rules to the iptables of the host computer, the routing rules include: between gateways 2 and be...

Abstract
The invention belongs to the technical field of communication, and discloses an OpenVPN cluster, including a plurality of VPN instances, some VPN instances communicate with gateways of peripheral devices, and some VPN instances communicate with clients of peripheral devices; the OpenVPN cluster stores Routing rules and routing tables, the routing rules include: communication between gateways and terminal devices connected to the gateways is prohibited through VPN instances; the routing table includes routing paths between any VPN instances, clients and corresponding VPN Routing paths between instances, routing paths between gateways and corresponding VPN instances; each VPN instance performs data transmission according to routing rules and routing tables. The OpenVPN cluster enables the client to connect to the gateway without being limited by the number of gateways or the bandwidth of a single VPN instance, thereby improving the stability and performance of the network. At the same time, the present invention also provides a method for constructing the OpenVPN cluster and a communication method based on the OpenVPN cluster. , A system based on the OpenVPN cluster.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to an OpenVPN cluster and its construction method, communication method and system. Background technique [0002] The applicant Chengdu Weishitong Information Industry Co., Ltd. filed an invention patent application CN201410462379.8 in 2014, which disclosed a load-balancing SSL VPN device cluster system and its working method. The system includes a main controller. The SSL VPN device of the node, and several SSL VPN devices serving as working nodes; all SSL VPN devices are provided with an intra-group synchronization module, and the master node SSL VPN device is also provided with a load management module, an address responder, and a data splitter; The cluster uniformly provides a globally set virtual IP address to the outside world, and uses the IP address as the DNS resolution address of a virtual single SSL VPN device; the entire SSL VPN device cluster is connected to netwo...
