Problems solved by technology

[0003] After VXLAN introduces the overlay technology, although it is possible to send data packets by superimposing the tenant's packets on the operator's network, it is precisely because the tenant's packets are directly superimposed on the operator's network. Therefore, the operator cannot directly determine which tenant the above-mentioned data packet belongs to from the data it sends, and thus cannot monitor and count the traffic of the tenant

Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0045] figure 1 It is a schematic flowchart of the first data sending method provided in the embodiment of the present application, and the method is applied to network devices.

[0046] In practical applications, a virtual user network generally corresponds to a tenant, and a tenant may correspond to multiple virtual machines. Specifically, the data sent based on the virtual user network can be divided into the following situations:

[0047] The first type: send data between two virtual m...

Abstract

The embodiment of the application discloses a data sending method and device, relating to the network technical field, and is applied to network equipment. The method comprises: determining the virtual user network to which a received data message belongs; when determining the data message needs to be transferred through a tunnel, calculating the first identification corresponding to the virtual user network to obtain the second identification corresponding to the virtual user network, wherein the length of the second identification is no greater than the usable length of a preset filed in an Internet protocol IP header; performing tunnel encapsulation on the data message, wherein the preset filed in the external IP header of an encapsulated data message carries the second identification; and transferring the encapsulated data message through the tunnel. The data sending method and device can send data messages, and allow service providers to determine the lessees to which the data messages belong.

Description

technical field [0001] The present application relates to the field of network technologies, in particular to a method and device for sending data. Background technique [0002] With the rapid development of network technology, virtualized network technology has been used more and more in practical applications. In practical applications, one virtual user network generally corresponds to one tenant, and one tenant may correspond to multiple virtual user networks. Common virtual user networks such as VXLAN (Virtual eXtensible Local Area Network, Virtual Extensible Local Area Network), VXLAN uses a large layer-2 virtualization network technology, compared with VLAN, VXLAN introduces overlay (coverage) technology, can maximize Meet the needs of tenants. [0003] After VXLAN introduces the overlay technology, although it is possible to send data packets by superimposing the tenant's packets on the operator's network, it is precisely because the tenant's packets are directly su...
