Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the prior art, when transmitting an extensible virtual local area network VXLAN message, a virtual channel End Point (VTEP) node is configured in a virtual machine and a server, respectively, to implement encapsulation and decapsulation of the extensible virtual local area network VXLAN message.

The specific execution steps are that the virtual machine sends the data frame to the VTEP node of the virtual machine, the VTEP node adds a VXLAN header to the data frame, the VXLAN header comprises a VXLAN network identifier VNI, an outer layer source IP address and an outer layer destination IP address, then the VXLAN header and the data frame are encapsulated into a VXLAN message and sent to the VTEP node deployed at the server end; and the VTEP node deployed at the server decapsulates the received VXLAN message to obtain a data frame encapsulated therein, processes the data frame, encapsulates the processed data frame, the VXLAN network identifier VNI obtained in the decapsulation process, the outer layer source IP address and the outer layer destination IP address together, and sends the encapsulated data frame, the outer layer source IP address and the outer layer destination IP address to the VTEP node corresponding to the virtual machine.

As can be seen from the above execution steps, the server needs to process the data frame sent by the virtual machine, and also needs to execute the steps of VLAN packet encapsulation and VXLAN packet decapsulation.

Based on the above, the present scheme provides a message transmission method, through setting the backflow switch, the processes of VLAN message encapsulation and VXLAN message decapsulation are completed, and the server only needs to process the VLAN message sent by the backflow switch, thereby reducing the performance consumption of the server.

To facilitate understanding of the embodiment, a detailed description is first given to a message transmission method disclosed in the embodiment of the present application.

Example one

Referring to fig. 1, an interactive flow diagram of a message transmission method provided in the embodiment of the present application is shown, which includes the following steps:

step 101, the virtual machine sends the VXLAN message to a return switch.

And 102, the return switch receives the extensible virtual local area network VXLAN message sent by the virtual machine, and analyzes the extensible virtual local area network VXLAN message to obtain message encapsulation information contained in the extensible virtual local area network VXLAN message and an original message.

Step 103, the return switch determines, based on the message encapsulation information, a transmission port between the virtual machine and the server corresponding to the message encapsulation information, and determines identifier information corresponding to the message encapsulation information.

And 104, the return switch packages the original message based on the identifier information to obtain a Virtual Local Area Network (VLAN) message corresponding to the original message.

And 105, the return switch transmits the VLAN message to the server through the transmission port.

And 106, the server processes the received VLAN message and sends the processed VLAN message to a return switch.

And 107, the return switch receives the VLAN message sent by the server, analyzes the head of the VLAN message, acquires the identifier information, and determines the message encapsulation information based on the identifier information.

And step 108, the return switch packages the VLAN message based on the message packaging information to obtain an extensible virtual local area network VXLAN message.

And step 109, the return switch sends the VXLAN message to the virtual machine.

It should be noted that the communication process between the virtual machine and the server is executed through the return switch, the virtual machine and the return switch communicate based on the extensible virtual local area network VXLAN message, and the return switch and the server communicate based on the virtual local area network VLAN message.

The following is a detailed description of steps 101 to 109.

For step 101:

the header of an extensible virtual local area Network VXLAN message sent by a virtual machine carries a VXLAN Network Identifier (VNI), outer layer source IP address information, and outer layer destination IP address information, where the outer layer destination IP address information is IP address information of a server that the virtual machine needs to communicate with. The server has only one corresponding reflow switch, so the virtual machine can determine the reflow switch to be sent through the outer layer destination IP address.

In actual implementation, communication can be performed only between devices in the same VXLAN network, so that it can be determined whether the virtual machine and the server are in the same VXLAN network according to the VXLAN network identifier VNI, and further determined whether the virtual machine is allowed to send a VXLAN message to a return switch corresponding to the external destination IP address information of the virtual machine.

With respect to step 102:

the return switch can analyze the received extensible virtual local area network VXLAN message to obtain message encapsulation information contained in the extensible virtual local area network VXLAN message and an original message. The message encapsulation information includes a VXLAN network identifier VNI, outer layer source IP address information, and outer layer destination IP address information, and the message type of the original message may be a VLAN message.

For step 103:

in a possible implementation manner, a mapping relationship table may be stored in advance in the return switch, where the mapping relationship table stores mapping relationships between the packet encapsulation information and the transmission ports and between the packet encapsulation information and the identifier information. After the message encapsulation information is obtained by analyzing the reflux switch, the transmission port between the virtual machine and the server and the identifier information corresponding to the message encapsulation information can be determined according to the message encapsulation information. Specifically, the return switch may search, according to the packet encapsulation information obtained by the analysis, a transmission port between the virtual machine and the server and identifier information corresponding to the packet encapsulation information in the mapping relationship table.

For example, the mapping relationship table may be as shown in table 1 below:

TABLE 1

The VXLAN network identifier VNI, the outer layer source IP address information, and the outer layer destination IP address information may be regarded as a set of data, and when the VXLAN network identifier VNI, the outer layer source IP address information, and the outer layer destination IP address information are determined, a uniquely determined transmission port and an identifier are corresponding to each other in the mapping relationship table.

For example, if the VXLAN network identifier VNI is "123", the outer-layer source IP address information is "234", and the outer-layer destination IP address information is "345", based on table 1 above, the corresponding transmission port is a, and the identifier is 1.

With respect to step 104:

after determining the transmission port between the virtual machine and the server and the identifier information corresponding to the message encapsulation information, the return switch may encapsulate the original message according to the identifier information.

Specifically, when the original message is encapsulated according to the identifier information, it may be detected whether the VLAN header position in the original message is empty, if the VLAN header position of the original message is empty, a VLAN header is newly encapsulated for the original message, and the identifier information is added to the newly encapsulated VLAN header, so as to obtain a VLAN message 1 of the virtual local area network corresponding to the extensible virtual local area network VXLAN message 1. Illustratively, the identifier information may be added to the 3 rd and 4 th bytes of the newly encapsulated VLAN header, and in another example, the addition position of the identifier information in the VLAN header may be predetermined by the server and the reflow switch.

If the VLAN header position of the original packet is not null, the identifier information may be added to the innermost layer of the original packet, or if the VLAN header position of the original packet is not null, the identifier may be added to a position that is pre-agreed by the server and the return switch.

With respect to step 105:

in one possible application scenario, a switch may be connected to multiple servers, and a server may be connected to a switch, so that the selection of servers may be implemented through different ports on the switch.

Based on step 104, while determining the VLAN packet corresponding to the VXLAN packet, the return switch may also determine a transmission port between the return switch and the server, so that after determining the VLAN packet corresponding to the VXLAN packet, the return switch may send the VLAN packet to the server through the determined transmission port.

For step 106:

because the server has only a single switch connected to it, the server can send the processed VLAN message to the return switch through the port connected to the switch.

It should be noted that the VLAN packet in the step after step 106 is a processed VLAN packet sent by the server to the return switch.

For step 107:

in practical applications, the switch is connected to multiple servers, and therefore, the switch may process VLAN packets sent back by multiple servers at the same time. In order to determine the virtual machine corresponding to the VLAN packet, the VLAN packet sent back by each server may carry identifier information, and then the return switch may search for corresponding packet encapsulation information according to the identifier information, and determine the virtual machine corresponding to the VLAN packet based on the packet encapsulation information.

In specific implementation, after receiving a VLAN message sent by a server, a reflux switch may parse the header of the VLAN message, obtain identifier information, determine message encapsulation information based on the identifier information, and then encapsulate the VLAN message based on the message encapsulation information to obtain an extensible VLAN VXLAN message.

The identification symbol information may be obtained at a position in a header of a VLAN packet of a virtual local area network that is pre-agreed by the reflux switch and the server when obtaining the identification symbol information, for example, the reflux switch and the server are pre-agreed, and when the server sends the VLAN packet, the identification symbol information is added to the 3 rd and 4 th sections of the VLAN header, so that when the reflux switch analyzes the VLAN packet, the identification symbol information may be directly obtained from the 3 rd and 4 th sections of the VLAN header.

In a possible implementation manner, when determining the packet encapsulation information based on the obtained identifier information, the packet encapsulation information corresponding to the identifier information may be searched in a mapping relationship table pre-stored in the return switch according to the packet encapsulation information.

For step 108:

in an example of the present application, when a VLAN packet is encapsulated based on packet encapsulation information, a header of the VLAN packet may be deleted, a new VLAN packet header is encapsulated for the VLAN packet with the header deleted, packet encapsulation information is added to the newly encapsulated header, and then the VLAN packet after the new header is added is encapsulated into an extensible VLAN VXLAN packet.

For step 109:

it should be noted that, in the process of transmitting data to the virtual machine by the server, the meanings represented by the outer layer source IP address information and the outer layer destination IP address information have changed. In the process of transmitting data to the server by the virtual machine, the outer layer source IP address is the IP address of the virtual machine, the outer layer destination IP address is the IP address of the server, and the virtual machine transmits data to the outer layer destination IP address in the process of transmitting data; in the process of transmitting data to the virtual machine, the server transmits data to the outer layer source IP address instead of transmitting data to the outer layer destination IP address.

When the extensible virtual local area network VXLAN message is sent to the virtual machine, the extensible virtual local area network VXLAN message can be sent to the virtual machine corresponding to the outer layer source IP address information.

In the message transmission method provided by this embodiment, after receiving an extensible virtual local area network VXLAN message sent by a virtual machine, a return switch determines identifier information and an original message corresponding to the message encapsulation information based on message encapsulation information in the extensible virtual local area network VXLAN message, and encapsulates the original message according to the identifier information to obtain a virtual local area network VLAN message corresponding to the original message; after receiving the VLAN message sent by the server, the message encapsulation information is determined according to the identification symbol information in the VLAN message, and the VLAN message is encapsulated based on the message encapsulation information to obtain an extensible virtual local area network VXLAN message. The reflux switch is arranged between the virtual machine and the reflux switch, so that the decapsulation of the extensible virtual local area network VXLAN message and the encapsulation of the virtual local area network VLAN message are completed, and the server only needs to process the virtual local area network VLAN message sent by the reflux switch, so that the performance consumption of the server is reduced, and the response rate of the server is improved.

In order to ensure the connection between the server and the virtual machine, when the connection between the server and the virtual machine fails, a worker is prompted to perform maintenance in time, and in another possible implementation manner of the present application, failure Detection may be performed through Bidirectional Forwarding Detection (BFD).

Specifically, the IP address of the server may be used as a destination IP address, the IP address of the virtual machine may be used as a source IP address, then the BFD message is sent to the server through the virtual machine, after the backflow switch receives the BFD message sent by the virtual machine, the server to be sent and a corresponding port of the server in the backflow switch are determined directly according to the destination IP address in the BFD message, and then the BFD message is sent to the server directly through the port.

In the reverse test, the IP address of the server may be used as a source IP address, the IP address of the virtual machine may be used as a destination IP address, a BFD message is sent to the virtual machine through the server, and after receiving the BFD message sent by the server, the return switch determines the virtual machine to be sent directly according to the destination IP address in the BFD message, and then sends the BFD message to the corresponding virtual machine.

In the detection process, if any one party does not receive the BFD message, an alarm is triggered, and the specific process will not be described here.

In a possible application scenario, the message types received by the return switch include a BFD message, a VLAN message, and an VXLAN message, and after receiving any one of the messages, the return switch determines the message type of the message, and then performs different processing based on different message types.

Illustratively, if the type of the received message is a BFD message, forwarding the BFD message according to a destination IP address in the BFD message; if the received message type is a Virtual Local Area Network (VLAN) message, analyzing the VLAN message to obtain identifier information, then determining message encapsulation information based on the identifier information, encapsulating the VLAN message based on the message encapsulation information to obtain an extensible virtual local area network (VXLAN) message, and sending the extensible virtual local area network (VXLAN) message to a virtual machine; if the received message type is an extensible virtual local area network VXLAN message, analyzing the extensible virtual local area network VXLAN message to obtain message encapsulation information and an original message, then determining identification symbol information and a transmission port based on the message encapsulation information, encapsulating the original message based on the identification symbol information to obtain a virtual local area network VLAN message corresponding to the original message, and transmitting the virtual local area network VLAN message based on the transmission port. The specific execution process refers to steps 101 to 109 described above.

The embodiment also provides a message transmission method, which is a flow diagram of the message transmission method provided in the embodiment of the present application, and is shown in fig. 2, where the method is applied in a return switch, and includes the following steps:
