The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0050] The embodiments of the present application provide a message forwarding method and related devices for a virtual switch, which are described in detail below.

[0051] like Figure 1 As shown, Figure 11 is a schematic diagram of a scenario of a message forwarding system for a virtual switch provided in an embodiment of the present application. The message forwarding system for a virtual switch may include a computer device 100, in which a message forwarding device for a virtual switch is integrated, such as Figure 1 A computer device 100 in FIG.

[0052] In the embodiment of the present application, the computer device 100 may be a terminal or a server. When the computer device 100 is a server, it may be an independent server, or a server network or server cluster composed of servers. For example, the computer device 100 described in the embodiment of the present application includes but is not limited to a computer, a network host, a single network server, a plurality of network server sets or a cloud server constructed by a plurality of servers. The cloud server is constructed by a large number of computers or network servers based on cloud computing.

[0053] It is understandable that when the computer device 100 in the embodiment of the present application is a terminal, the terminal used may be a device including both receiving and transmitting hardware, that is, a device having receiving and transmitting hardware capable of performing two-way communication on a two-way communication link. Such a device may include: a cellular or other communication device having a single-line display or a multi-line display or a cellular or other communication device without a multi-line display. The specific computer device 100 may be a desktop terminal or a mobile terminal, and the computer device 100 may also be one of a mobile phone, a tablet computer, a laptop computer, etc.

[0054] Those skilled in the art will understand that Figure 1 The application environment shown in the figure is only one application scenario of the present application solution, and is not intended to limit the application scenario of the present application solution. Other application environments may also include Figure 1 More or less computer equipment as shown in Figure 1 Only one computer device is shown in the figure. It can be understood that the message forwarding system for the virtual switch can also include one or more other computer devices, which are not specifically limited here.

[0055] In addition, if Figure 1 As shown, the message forwarding system for the virtual switch may further include a memory 200 for storing data, such as storing user account information corresponding to the user terminal.

[0056] It should be noted that Figure 1The scenario diagram of the message forwarding system for the virtual switch shown is only an example. The message forwarding system and scenario for the virtual switch described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. A person of ordinary skill in the art can know that with the evolution of the message forwarding system for the virtual switch and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0057] For example, refer to Figure 4 , Figure 4 FIG. 1 is another schematic diagram of a message forwarding system for a virtual switch. Figure 4 In the example, the message sent by UE (User Equipment) is transmitted to vSwitch (Virtual Switch) via DCSW (Data Center SWitches). vSwitch generally needs to send the user message to vCPE (Virtual Customer Premise Equipment) for NAT (Network Address Translation) and other processing, and then transfer it back to vSwitch. vSwitch transmits the message processed by NAT and other processing to the external network via DCSW and BRAS (Broadband Remote Access Server) to achieve the purpose of user end surfing the Internet. It can be seen that the forwarding path of vSwitch is too long and the forwarding efficiency is low. Among them, the user end is in the intranet, that is, the local area network, and the external network is the wide area network. The communication between DCSW and vSwitch is based on VXLAN (Virtual Extensible Local Area Network) technology.

[0058] Next, a message forwarding method for a virtual switch provided in an embodiment of the present application is introduced.

[0059] In the embodiment of the message forwarding method for a virtual switch of the present application embodiment, a message forwarding device for a virtual switch is used as an execution subject. For the sake of simplicity and ease of description, the execution subject will be omitted in the subsequent method embodiments. The message forwarding device for a virtual switch is applied to a computer device.

[0060] See also Figure 2 , Figure 2 The present invention provides a flow chart of an embodiment of a method for forwarding a message for a virtual switch provided in an embodiment of the present application. The method for forwarding a message for a virtual switch is applied to the above-mentioned virtual switch, including:

[0061] 201. Receive a first message sent by a user terminal;

[0062] In an embodiment of the present application, the user terminal can access the external network by sending a first message, so the virtual switch can receive the first message.

[0063] In some embodiments of the present application, after receiving the first message sent by the user terminal, it may also include: determining the message type of the first message, the message type includes at least one of a forwarding message and a control message, the forwarding message is a user data message, and the control message is a protocol message; if the message type of the first message is a forwarding message, executing the step of detecting whether the virtual switch stores user account information corresponding to the user terminal. Among them, the forwarding message refers to the user traffic that needs to be forwarded to the external network, and the control message refers to the instruction for controlling the network connection with the external network, for example, the control message can be a dial-up Internet access instruction.

[0064] In some embodiments of the present application, after determining the message type of the first message, the method may further include: if the message type of the first message is a control message, sending the control message to the virtual client device to control the virtual client device to perform Internet dial-up control based on the control message. The control of Internet dial-up includes the establishment and disconnection of Internet dial-up, etc. It can be seen that this embodiment separates control messages from forwarding messages, that is, the virtual switch sends the control message to the virtual client device for processing, while the forwarding message does not need to be processed by the virtual client device, and is processed by the virtual switch and then sent to the external network, thereby realizing the separation of the forwarding plane and the control plane.

[0065] 202. Detect whether the virtual switch stores user account information corresponding to the user terminal, the user account information is used for network address translation, and the user account information is obtained from a virtual client device connected to the virtual switch;

[0066] In an embodiment of the present application, at least one user account information is stored in the virtual switch, and the user account information is obtained from the virtual client device. For example, after obtaining the user account information, the virtual client device can actively send the user account information to the virtual switch so that the virtual switch can store the user account information. Among them, the user account information is used to perform network address translation in the virtual client device. In an embodiment of the present application, the user account information is stored in the virtual switch in advance so that the virtual switch can perform network address translation processing instead of the virtual client device.

[0067] In some embodiments of the present application, the user account information is the relevant information on the user's dial-up network. For example, the user information includes the user's Internet dial-up information and IP allocation information. The IP allocation information may include the NAT IP information corresponding to the user, and the Internet dial-up information may be the outgoing sub-interface information. Of course, the user account information may also include some basic configuration information of the user account.

[0068] In some embodiments of the present application, detecting whether user account information corresponding to the user terminal is stored in the virtual switch may include: obtaining the virtualized network tunnel identifier (VNI, VXLAN Network Identifier) ​​and user terminal attribute information (i.e., qinq information, including CVLAN tag and SVLAN tag) in the first message; and detecting whether account information having the virtualized network tunnel identifier and user terminal attribute information is present in the multiple account information stored in the virtual switch to determine whether user account information corresponding to the user terminal is stored in the virtual switch. That is, based on the virtualized network tunnel identifier and the user terminal attribute information, the user account information is searched in the multiple account information.

[0069] 203. If the virtual switch stores user account information corresponding to the user terminal, perform network address translation on the first message based on the user account information to obtain a second message;

[0070] In the embodiment of the present application, if the virtual switch stores the user account information corresponding to the user terminal, it means that the first message does not need to be sent to the virtual client device, but the virtual switch directly performs network address translation and other processing to obtain the second message. It should be noted that in the process of obtaining the second message from the first message, in addition to the network address translation processing, it can also include the replacement of the outer tunnel header, inner header and other information in the first message.

[0071] In some embodiments of the present application, after detecting whether the user account information corresponding to the user terminal is stored in the virtual switch, the method may further include: if the user account information corresponding to the user terminal is not stored in the virtual switch, feedback of prompt information of abnormal network connection is sent to the user terminal, so that the virtual client device can dial up to the Internet. It is understandable that if the user account information corresponding to the user terminal is not stored in the virtual switch, it indicates that the Internet dial-up processing of the virtual client device is unsuccessful or the virtual client device fails, so the prompt information of abnormal network connection can be fed back to the user terminal, so that the user terminal can re-trigger the control message for Internet dial-up, so that the virtual client device can re-dial up to the Internet.

[0072] 204. Send the second message to the external network.

[0073] In the embodiment of the present application, the virtual switch transmits the second message to the external network via the DCSW and the BRAS, thereby enabling the user end to access the external network.

[0074] The message forwarding method for a virtual switch provided in the embodiment of the present application, by synchronizing the user account information in the virtual client device to the virtual switch for the virtual switch to perform network address translation, does not need to send the message to the virtual client device for network address translation, shortens the flow forwarding path of the virtual switch, and improves the flow forwarding efficiency of the virtual switch. It also has high fault tolerance, and the abnormality of the virtual client device will not affect the existing users' Internet access.

[0075] See also Figure 3 , Figure 3 This is a flow chart of another embodiment of a message forwarding method for a virtual switch provided in an embodiment of the present application. The message forwarding method for a virtual switch is applied to the above-mentioned virtual client device, including:

[0076] 301. Obtain user account information assigned to the client;

[0077] In an embodiment of the present application, the virtual client device is used to realize the connection between the access network (ie, the external network) and the user terminal. When establishing the connection between the access network and the user terminal, the virtual client device can automatically generate the user account information of the user terminal.

[0078] In some embodiments of the present application, obtaining user account information assigned to a user terminal may include: performing PPPOE Internet dial-up processing based on a control message sent by the user terminal for Internet dial-up to obtain Internet dial-up information of the user terminal; allocating an IP address to the user terminal to obtain IP allocation information of the user terminal, wherein the user terminal may request a virtual client device to allocate an IP address through DHCP (Dynamic Host Configuration Protocol).

[0079] 302. Send the user account information to the virtual switch, wherein the virtual switch stores the user account information, performs network address translation on the first message sent by the user terminal based on the user account information to obtain a second message, and sends the second message to the external network.

[0080] In an embodiment of the present application, after obtaining the user account information, the virtual client device may publish the user account information to the virtual switch through Redis (Remote Dictionary Server) to implement network address translation processing in the virtual switch.

[0081] The solution disclosed in the embodiment of the present application stores the user account information in the virtual client device in the virtual switch for the virtual switch to perform network address translation, without sending the message to the virtual client device for network address translation, thereby shortening the traffic forwarding path of the virtual switch and improving the traffic forwarding efficiency of the virtual switch.

[0082] The following is an example of the data processing flow of the virtual switch:

[0083] 1. The virtual switch receives the first message from the physical port;

[0084] 2. The virtual switch parses the outer tunnel header of the first message and extracts the VNI;

[0085] 3. The virtual switch parses the inner double-layer VLAN header of the first message and extracts the QinQ information;

[0086] 4. The virtual switch finds the user account information locally based on the vni+qinq information and exits the tunnel;

[0087] 5. The virtual switch directly uses the encapsulated message information under the user account information to fill the outer tunnel header and inner header (eth header + double-layer vlan header + PPPOE header) of the first message, where the Eth header includes the source MAC address and the destination MAC address, and PPPOE refers to the Ethernet-based point-to-point communication protocol);

[0088] 6. The virtual switch searches the flow table and performs the NAT function to replace the inner IP and port of the first message to obtain the second message.

[0089] 7. The virtual switch forwards the second message to the outgoing tunnel and sends it to the external network.

[0090] The following is an example of the data processing flow of a virtual client device:

[0091] 1. After the virtual client device configures the account information table, it publishes the basic account information to the virtual switch through redis;

[0092] 2. After the virtual client device successfully performs PPPOE dial-up based on the basic account information, it publishes Internet dial-up information to the virtual switch through redis;

[0093] 3. After the user requests the virtual client device to allocate an IP address through DHCP, the virtual client device publishes the account IP allocation information to the virtual switch through redis.

[0094] In order to better implement the message forwarding method for a virtual switch in the embodiment of the present application, based on the message forwarding method for a virtual switch, the embodiment of the present application also provides a message forwarding device for a virtual switch, such as Figure 5 As shown, the message forwarding device 500 for the virtual switch includes:

[0095] The receiving unit 501 is configured to receive a first message sent by a user terminal;

[0096] A detection unit 502 is used to detect whether the virtual switch stores user account information corresponding to the user terminal, the user account information is used for network address translation, and the user account information is obtained from the virtual client device connected to the virtual switch;

[0097] The conversion unit 503 is configured to perform network address translation processing on the first message based on the user account information to obtain a second message if the user account information corresponding to the user terminal is stored in the virtual switch;

[0098] The sending unit 504 is used to send the second message to the external network.

[0099] The message forwarding device for a virtual switch provided in an embodiment of the present application stores user account information in a virtual client device in the virtual switch for the virtual switch to perform network address translation, without the need to send the message to the virtual client device for network address translation, thereby shortening the traffic forwarding path of the virtual switch and improving the traffic forwarding efficiency of the virtual switch.
