Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Such as Figure 1 to Figure 3 As shown, the present invention utilizes the Keepalvied of the virtual router redundancy protocol (VRRP, VirtualRouter Redundancy Protocol) realized, a plurality of Linux servers are virtualized into a virtual IP, so that when one of the servers fails, the virtual IP Drift to other servers to achieve high network reliability.

[0031] The method that the cloud-to-cloud environment GRE tunnel realizes communication disclosed by the present invention comprises the following steps:

[0032] Step 1) Configure GRE Tunnel

[0033] Enable the gre module on the server and enable the routing and forwarding function.

[0034] Create the first public virtual machine S1 and the second public virtual machine S2 under the network segment of the public cloud S;

[0035] Establish the first private virtual machine C1 and the second private vi...

Abstract

According to a method for realizing communication of the GRE tunnels in the cloud-to-cloud environment, disclosed by the invention, load balancing of channels can be realized by configuring a plurality of routes reaching the same target address, that is, two tunnels work at the same time and share direct network communication flow of two clouds under a hybrid cloud architecture at the same time. The high-reliability purpose is achieved. According to the invention, the GRE tunnel and the Keepalived tunnel are matched, and the two GRE tunnels are mutually main and standby, so that the high reliability of the whole network is realized.

Description

technical field [0001] The invention relates to the field of computer network communication, in particular to a method for realizing communication through a GRE tunnel in a cloud-to-cloud environment. Background technique [0002] With the rapid development of cloud computing, more and more enterprises are migrating their applications to the public cloud, while synchronizing data back to the private cloud, forming a hybrid cloud architecture. The hybrid cloud architecture must first solve the problem of network connectivity between the two cloud environments. Common solutions include public network VPN and physical dedicated line. Compared with physical dedicated line, public network VPN has the characteristics of low cost and easy operation. Lightweight application scenarios with no special requirements on network quality can basically meet the requirements. [0003] A GRE tunnel can be implemented on a Linux virtual machine through simple configuration to achieve network ...
