Abstract

The invention discloses a message transmission method and device, and the method is applied to an operator edge router at a cloud side, and comprises the steps: receiving and analyzing a first forwarding message through a first tunnel between the first tunnel and a virtual gateway, and obtaining an identifier of the first tunnel and an original message; determining an identifier of a second tunnel between the first tunnel and an operator edge router on the user side according to the identifier of the first tunnel, and packaging the original message and the identifier of the second tunnel according to a preset protocol of the second tunnel to obtain a second forwarding message; forwarding the second forwarding message to an operator edge router of the user side through a second tunnel, so that the operator edge router of the user side sends the original message to the target user side device according to an identifier of the second tunnel, wherein the identifier of the second tunnel is used for determining a tenant identifier of the target user side device. In this way, isolation of tenant routing and data can be achieved in the scene that the flow from the cloud side network to the user side network is forwarded based on the bearer network.

Description

technical field [0001] The embodiments of the present application relate to, but are not limited to, the field of network technologies, and in particular, relate to a packet transmission method and device. Background technique [0002] In a multi-tenant scenario, in order to ensure the security of tenant data, it is necessary to isolate tenants so that virtual machines within tenants can communicate with each other, while virtual machines between tenants are isolated from each other, that is, tenant isolation. In the related art, only the mapping technology from Virtual Extensible Local Area Network (VXLAN) to Virtual Local Area Network (VLAN) is applied to tenant isolation in a multi-tenant scenario, and there is no mapping between the virtual network and the virtual local area network (VLAN). The traffic forwarding between the underlying physical bearer networks implements tenant isolation. SUMMARY OF THE INVENTION [0003] In view of this, the present application provi...
