Embodiment Construction

[0033] In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0034] see figure 2 , figure 2 It is a schematic structural diagram of an embodiment of a network system composed of data centers in this application. The network system includes a plurality of data centers, and data centers can communicate with each other. In this embodiment, the network system includes three data centers including a first data center 110 , a second data cente...

Abstract

The present application discloses a method, gateway and system for synchronizing virtual machine location information between data center gateways, wherein the method includes: the second gateway of the second data center receives the first location sent by the first gateway of the first data center An update message, wherein the first location update message is sent by the first gateway when it detects that the first virtual machine migrates across data centers to the first data center, and is used to notify that the location information of the first virtual machine has changed ; The second gateway deletes the MAC route of the first virtual machine saved by the second gateway according to the first location update message; when the second gateway receives a message sent to the first virtual machine, and the first When the second gateway does not save the MAC route of the first virtual machine, the second gateway learns from the first virtual machine to obtain the current location information of the first virtual machine. Through the foregoing manner, accurate synchronization of virtual machine location information between data centers can be achieved.

Description

technical field [0001] The present application relates to the communication field, in particular to a method, a gateway and a system for synchronizing virtual machine position information between data center gateways. Background technique [0002] Currently, virtual machine migration is possible between interconnected data centers. After the virtual machine is migrated across data centers, the location information of the virtual machine will change, so the interconnected data centers need to update the outgoing interface of the virtual machine in the local MAC routing table to synchronize the location information of the virtual machine. So that all data centers can correctly forward the data flow accessing this virtual machine. [0003] Existing methods for synchronizing location information of virtual machines after migration are as follows: [0004] Such as figure 1 , after the first virtual machine (English: virtual machine, VM for short) 112 is migrated from the secon...
