Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the present application clearer, the solution of the present application will be further described in detail below with reference to the accompanying drawings.

[0019] In order to solve the problems in the prior art, the present invention provides a message isolation method and device.

[0020] figure 1 It is a schematic diagram of the network environment where the message isolation method of the present invention is located. The network includes a plurality of VTEP devices (such as VTEP1, VTEP2 and VTEP3) and hosts (such as VM1 connected to VTEP1) connected to the VTEP devices respectively. Each VTEP device also It has multiple ports (for example, Port1 and Port2 on VTEP1).

[0021] Please refer to figure 2 , a schematic diagram of the processing flow of the message isolation method provided by the present invention, the message isolation method can be applied to a local VTEP device, and the message...

Abstract

The present invention provides a message isolation method and device, wherein the method includes: receiving a message, obtaining source isolation group information corresponding to the source address of the message; According to the forwarding information corresponding to the destination address of the message, the destination isolation group information corresponding to the destination address of the message is obtained according to the forwarding information; when it is determined that the source isolation group information is consistent with the destination isolation group information, according to the The isolation attribute in the destination isolation group information processes the packet. The invention realizes precise isolation of messages in the same VXLAN instance, effectively reduces equipment load in the VXLAN network, and improves equipment performance.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message isolation method and device. Background technique [0002] When the hosts in the VXLAN network communicate with each other, the VTEP (VXLAN TunnelEnd Point, VXLAN tunnel endpoint) device connected to the source VM can identify the VXLAN instance to which the source VM belongs, and learn the source VM information belonging to the same VXLAN instance. Then encapsulate the packet sent by the source VM into a VXLAN packet, search for the corresponding tunnel information according to the destination address of the packet, and forward the VXLAN packet to the VTEP device connected to the destination VM according to the tunnel information. If the VTEP device does not find the corresponding tunnel information according to the destination address of the packet, it will encapsulate the packet into a VXLAN packet and flood it in the VXLAN instance to which the source...
