Problems solved by technology

[0003] The disadvantage of adopting this solution is that the multi-tenant network slicing in the SD-WAN backbone network itself is very complicated. In addition, the establishment of an overlay network based on the Internet, optical fiber and other underlay networks using IPSec technology, how to manage thousands of The technology of IPSec tunnels is more complicated. In addition, IPSec needs to be combined with VXLAN, which is equivalent to doubling the management complexity. That is, the overlay network needs to manage IPSec tunnels and VxLAN tunnels at the same time, and maintain two tunnel information

Embodiment 1

[0046]SD-WAN is a service formed by applying SDN technology to wide area network scenarios. This service is used to connect enterprise networks with a wide geographical range, including enterprise branches and data centers. In the following, the present invention is described by taking SD-WAN service as a specific application example.

[0047] The SD-WAN architecture that supports cloud computing adds a network service provider point (POP point) on the backbone network to utilize and manage Internet broadband, build a more powerful network for enterprise applications, and improve its performance to a new level.

[0048] Such as figure 1 As shown, the SD-WAN backbone network includes a management and control platform, a network service provider (POP) point, and a client equipment (CPE). The management and control platform is connected to all devices in the SD-WAN backbone network to realize global monitoring of all devices Deployment and control functions. For simplicity, the...

Abstract

The invention provides a data forwarding method and a data forwarding device based on tenant information. The method comprises the following steps: establishing a VPN channel between a network serviceproviding point and client equipment, wherein the network service providing point stores a first corresponding relationship between VPN channel information and tenant information, the VPN channel information is used for uniquely identifying the VPN channel, and the tenant information is used for uniquely identifying a tenant to which the client device belongs; the network service providing pointreceives a data packet from the client device, and obtains target VPN channel information from the data packet; the network service providing point queries target tenant information corresponding to the target VPN channel information from the first corresponding relationship; and the network service providing point forwards the data packet to a preset virtual machine corresponding to the target tenant information.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a data forwarding method and data forwarding device based on tenant information. Background technique [0002] The existing SD-WAN architecture that supports cloud computing establishes multiple network service provider (POP) points on the SD-WAN backbone network, and uses the VXLAN+IPSec architecture to distinguish the traffic of different users on the SD-WAN backbone network. Use VXLANtagid to identify the traffic of different tenants. At the POP point, different VXLAN IDs are used to match different tenants. According to the policies of different tenants' traffic arrangement, the corresponding traffic is dispatched to different security resource pools for corresponding processing. Since the length defined by a single VXLANIDRFC is 24 bits and supports a maximum of 16M, a single POP point can support a maximum of 16M tenant access. [0003] The disadvantage of a...
