Problems solved by technology

[0004] When there are a large number of VPNs in the distributed data center network, since IPsec tunnels need to be established individually for each VPN, a large number of IPsec tunnels need to be established, which wastes the resources of IPsec tunnels
Moreover, the public network address needs to be used when establishing an IPsec tunnel, so a large amount of public network address resources will be occupied

Abstract

The application provides a message transmission method and a message transmission device. The method comprises the following steps: after receiving a first message, determining VPN (Virtual Private Network) information corresponding to the first message, and querying a forwarding table corresponding to the VPN information according to the destination IP address of the first message to get an outbound interface corresponding to the destination IP address; if the outbound interface is a GRE (Generic Routing Encapsulation) tunnel, packaging a first GRE tunnel header corresponding to the GRE tunnel for the first message to get a first GRE tunnel message, wherein the first GRE tunnel header contains the VPN information; acquiring an IPsec (IP Security) tunnel corresponding to the GRE tunnel, and packaging a first IPsec tunnel header corresponding to the IPsec tunnel for the first GRE tunnel message to get a first IPsec tunnel message; and sending the first IPsec tunnel message through the IPsec tunnel so that opposite-end equipment receiving the first IPsec tunnel message can send the first message according to the VPN information. Through the technical scheme of the application, the resources of the IPsec tunnel can be saved, and the public network address resources can be saved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message transmission method and device. Background technique [0002] IPsec (IP Security, IP Security) is a three-layer tunnel encryption protocol. IPsec provides high-quality, cryptography-based security guarantees for data transmitted on the Internet. It is a traditional implementation of three-layer VPN (Virtual Private Network, virtual private network) security technology. IPsec protects user data that needs to be transmitted by establishing a "channel" between specific communicating parties. This channel is called an IPsec tunnel. [0003] In the distributed data center network, IPsec+VPN technology is used between different data centers to transmit user data. Specifically, an IPsec tunnel is established between gateway devices in different data centers, and an IPsec tunnel is independently established for each VPN. For example, between gateway devi...
