All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a network switching method, where the network switching method may be applied to a first electronic device, and the first electronic device may be applied to a network switching system, as shown in fig. 1, which is a structural diagram of the network switching system provided in the embodiment of the present invention, where the network switching system includes:
a first electronic device 11, a second electronic device 12, and a server 13; wherein, the first electronic device 11 includes: at least one virtual machine 111, and a first virtual switch 112 having a communication connection with the at least one virtual machine 111, respectively; the server 13 is a data transmission bridge between the first electronic device 11 and the second electronic device 12.
The first electronic device 11 may further comprise a switch 113 for communicating with the second electronic device, the switch 113 being different for different types of virtual networks; for example, if the electronic device is in the first virtual network, the first virtual switch 112 in the first electronic device 11 interacts with the virtual machine in the second electronic device 12 through the second switch 1131. If the virtual machine is in the second virtual network, the first virtual switch 112 in the first electronic device 11 interacts with the virtual machine of the second electronic device 12 through the third switch 1132.
In an embodiment of the present invention, after the virtual network is switched, for example, after the virtual network is switched from the second virtual network to the first virtual network, the first electronic device 11 generally does not switch from the first virtual network to the second virtual network again, and therefore, in an optional embodiment, in a class of virtual networks, the first electronic device only includes the second switch 1131 or the third switch 1132 corresponding to the virtual network; in an optional embodiment, during the switching process of the two types of virtual networks, the second switch 1131 or the third switch 1132 may be allowed to exist at the same time, so as to ensure that data in both types of virtual networks can be transmitted and received. After the virtual network is switched, the information corresponding to the second virtual network is deleted, so that the first virtual switch and the third switch 1132 are connected by a dotted line in fig. 1.
It is understood that the switch 113 may be a virtual switch or a physical switch, if the switch 113 is a virtual switch, the switch 113 is located inside the first electronic device, and if the switch 113 is a physical switch, the switch 113 is located outside the first electronic device, and fig. 1 illustrates the switch 113 as a virtual switch.
The following describes a network handover method provided in an embodiment of the present invention with reference to the structure of the network handover system, and as shown in fig. 2, is a flowchart of an implementation manner of the network handover method provided in the embodiment of the present invention, where the method includes:
step S201: establishing a second switch having a communication connection with the first virtual switch.
Wherein the second switch is configured to establish a communication channel between the first virtual switch and a second electronic device under a first virtual network, wherein the first virtual switch and a third switch have a communication connection before the second switch is established, the third switch is configured to establish the communication channel between the first virtual switch and the second electronic device under a second virtual network, and the first transmission network is different from the second virtual network.
The second switch is a virtual switch located in the first electronic device, or the second switch is a physical switch.
In an alternative embodiment, when the second switch is a virtual switch, the second switch may be a tunnel bridge br-tun and the first virtual switch may be a bridge br-int.
In an optional embodiment, the third switch is a virtual switch located in the first electronic device, or the third switch is a physical switch.
In an alternative embodiment, where the third switch is a virtual switch, the third switch may be a tunnel bridge br-prv.
Since the second switch is already established, the first electronic device may receive data transmitted by the second electronic device under the first virtual network.
Step S202: setting configuration information for establishing a communication channel between the at least one virtual machine and the second switch in the first virtual switch.
Before switching to the first virtual network, the virtual machine in the first electronic device communicates with the second electronic device through the first virtual switch and the third switch, so the first virtual switch stores configuration information for controlling a communication channel between the at least one virtual machine and the third switch in advance. In an optional embodiment, at this time, the first electronic device may interact with the second electronic device under the first virtual network and the second virtual network at the same time. The service flow between the first electronic device and the second electronic device under the second virtual network is not interrupted.
Step S203: and controlling the at least one virtual machine to interact with the second electronic equipment through the first virtual switch and the second switch under the first virtual network respectively based on the configuration information.
To sum up, the network switching method provided in the embodiment of the present invention first establishes the receiving channel and the sending channel between the first virtual network and the second electronic device, and the receiving channel and the sending channel in the first virtual network and the receiving channel and the sending channel in the second virtual network exist simultaneously in the switching process, so that the traffic of the service staff between the first electronic device and the second electronic device is not interrupted, and the problem of network capacity expansion is solved.
Generally, the virtual network of the first electronic device needs to be switched because the current second virtual network restricts the first electronic device, for example, assuming that the second virtual network is a VLAN network and the first virtual network is a VXLAN network, since the second virtual network allows 4096 user groups at most, if 4096 user groups are exceeded, the first electronic device needs to be switched from the second virtual network to the first virtual network.
In an optional embodiment, after the first electronic device may interact with the second electronic device under the first virtual network, configuration information preset in the first virtual switch and used for establishing a communication channel between the at least one virtual machine and the third switch may be deleted; and if the third switch is a virtual switch, deleting the third switch.
The embodiment of the invention provides a network switching method, wherein first electronic equipment comprises a virtual machine and a first virtual switch, and the virtual machine of the first electronic equipment interacts with the virtual machine in second electronic equipment (wherein the second electronic equipment is other electronic equipment except the first electronic equipment) through the first virtual switch and a third switch by using a second virtual network at the beginning; in order to ensure that the first electronic device can still perform normal interaction with the second electronic device in the second virtual network during the network switching process, the embodiment adopts a technology of establishing the second switch (a communication channel between the first virtual switch and the second electronic device can be established in the first virtual network), and setting configuration information for establishing a communication channel between a virtual machine in the first electronic device and the second switch in the first virtual switch, thereby implementing the network switching. Further, in the network switching method provided by the embodiment of the present invention, within a certain time, the first electronic device may simultaneously use the first virtual network and the second virtual network to respectively communicate with other electronic devices, so that, during the process of switching from the second virtual network to the first virtual network, the first electronic device does not need to migrate the virtual machine in the first electronic device, and during the process of switching the virtual networks, the first electronic device does not affect the communication with other electronic devices using the second virtual network.
After the first electronic device establishes the second switch and configuration information for establishing a communication channel between the at least one virtual machine and the second switch is set in the first virtual switch, the first electronic device can interact with the second electronic device through the first virtual network. And a proxy gateway is not needed, so that the performance loss during data packet forwarding is reduced.
The server 13 is configured to record information of a virtual network between the first electronic device and the second electronic device, and therefore, in an optional embodiment, the first electronic device needs to send, to the server 13 configured to manage the electronic device to use a virtual network type, indication information carrying a switch of the first electronic device from the second virtual network to the first virtual network.
In an optional embodiment, the establishing a second switch having a communication connection with the first virtual switch comprises:
setting a first flow table for establishing a reception channel for receiving a message from the second electronic device under the first virtual network;
setting a second flow table for establishing a transmission channel for transmitting a message to the second electronic device under the first virtual network.
In an optional embodiment, setting, in the first virtual switch, configuration information for establishing a communication channel between the at least one virtual machine and the second switch includes:
setting a third flow table for establishing a reception channel for receiving a message from the second switch;
setting a fourth flow table for establishing a transmission channel for transmitting a message to the second switch.

2. Setting a third flow table for establishing a reception channel for receiving a message from the second switch in the first virtual switch of the first electronic device.
That is, a receiving channel with the second electronic device is first established in the first electronic device.
At this time, the first electronic device may interact with the second electronic device in the second virtual network, or may receive data sent by the second electronic device in the first virtual network.
3. Setting a second flow table for establishing a transmission channel for transmitting a message to the second electronic device under the first virtual network in a second switch of the first electronic device.
4. And setting a fourth flow table for establishing a sending channel for sending the message to the second switch in the first virtual switch of the first electronic device.
A transmission channel is established in the first electronic device with the second electronic device.
Assuming that the first virtual network is a VXLAN network, the first electronic device and the second electronic device may interact under the VXLAN network.
As the third switch and the configuration information preset in the first virtual switch and used for establishing the communication channel between the at least one virtual machine and the third switch are not deleted; therefore, the first electronic device and the second electronic device can normally interact under both the first virtual network and the second virtual network.
In an alternative embodiment, steps 3 and 4 may be performed first, and then steps 1 and 2 may be performed.
5. The method comprises the step that a first electronic device sends instruction information carrying the first electronic device to be switched from the second virtual network to the first virtual network to a server for managing the electronic device to use the virtual network type.
