[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0020] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0021] At present, for the dual WAN network architecture, if a user's home has a 100M bandwidth from operator 1 and a 500M bandwidth from operator 2, if the slicing solution is not adopted, assuming that the allocation strategy of the two bandwidths is 1:1, that is, the corresponding bandwidth is used in a 1:1 order according to the service. When the user is preparing to play a game, other users visit a website and are allocated to the 500M link of operator 2. If the user plays the game immediately at this time, the game service will be allocated to the 100M bandwidth of operator 1. Because the game is very sensitive to latency, and bandwidth preemption is very likely to occur on the low-bandwidth link, resulting in excessive latency, which leads to a poor user experience after the dual WAN traffic is superimposed.

[0022] In order to solve the technical problem in the prior art that high-bandwidth services are allocated to low-bandwidth links under a dual WAN network architecture, the present application provides a data transmission method. For dual WANs, the allocation is based on the proportion of the number of connections created. Network slicing can be used to fix specific services or users to a certain link, thereby avoiding being divided into low-bandwidth links when the connection is created. Therefore, it can be ensured that important services can always occupy high-bandwidth links to improve the user's actual network experience.

[0023] Figure 1 A flowchart of a data transmission method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the steps of the method include:

[0024] Step 101, obtaining data to be transmitted, obtaining a preset corresponding relationship before transmitting the data to be transmitted, and determining a wide area network bandwidth corresponding to the data to be transmitted based on the preset corresponding relationship, wherein there are multiple wide area network bandwidths, and different wide area network bandwidths correspond to different bandwidths;

[0025] In an optional implementation manner of an embodiment of the present application, the data types in the embodiment of the present application may include: data divided based on user type, data divided based on service type, and data divided based on port. In a specific example, the data divided based on user type may refer to data corresponding to users of different priorities, such as VIP users and ordinary users, or users may be divided into more users of different priority levels, and specific settings may be made according to actual needs. Data divided based on service type may refer to web services, video services, voice services, etc. Data divided based on ports may refer to different ports, such as LAN1, LAN2, and LAN3, etc.

[0026] In addition, it should be noted that the bandwidths of the multiple WAN broadbands in the embodiment of the present application are different, so that data with high bandwidth requirements can be set to correspond to WAN broadbands with large bandwidths, so that the bandwidths of the multiple WAN broadbands can be fully utilized.

[0027] Step 102: Transmit the data to be transmitted based on the wide area network bandwidth corresponding to the data to be transmitted.

[0028] Through the above steps 101 and 102, before transmitting the data to be transmitted, the WAN bandwidth corresponding to the data to be transmitted can be determined based on the preset corresponding relationship, and the data to be transmitted can be transmitted based on the selected WAN broadband, thereby avoiding the data that does not have a corresponding relationship from being streamed with the WAN broadband, ensuring the high transmission performance of the data, improving the user experience, and solving the problem in the prior art that high-bandwidth data is allocated to a low-bandwidth link under a dual WAN network architecture.

[0029] In an optional implementation manner of the embodiment of the present application, the preset correspondence in the embodiment of the present application is used to characterize that each wide area network broadband corresponds to one or more types of data. Before obtaining the preset correspondence, the method of the embodiment of the present application may further include:

[0030] Step 11, classifying the user equipment corresponding to the data to be transmitted, and obtaining the user equipment type of the user equipment corresponding to the data to be transmitted;

[0031] Step 12: Based on the user equipment type, a preset correspondence relationship between different user equipment types and different wide area network bandwidths is established.

[0032] The user device types involved in the above steps 11 and 12 can be set accordingly according to different application scenarios. For example, in a company environment, users with large bandwidth requirements are set as VIP users, and users with low bandwidth requirements are set as ordinary users, that is, the user device types include VIP users and ordinary users. Among them, VIP users include IT staff or anchors used for live broadcasts, etc., and ordinary users can refer to civilian staff, etc. Based on this, two WAN bandwidths are pulled down in this application scenario, one is 500M and the other is 1000M, then the corresponding relationship between VIP users and 1000M WAN bandwidth is set, and the corresponding relationship between ordinary users and 500M WAN bandwidth is set. In actual use, ordinary users, such as ordinary civilian staff, can only use 500M bandwidth and cannot use 1000M bandwidth, which avoids ordinary users streaming to 1000M to affect the bandwidth usage of VIP users.

[0033] In an optional implementation manner of the embodiment of the present application, the method of determining the wide area network bandwidth corresponding to the data to be transmitted based on the preset corresponding relationship involved in the above step 101 may further include:

[0034] Step 21, determining a user equipment type of a user equipment corresponding to the data to be transmitted;

[0035] Step 22: Determine the wide area network bandwidth corresponding to the user equipment type based on the preset corresponding relationship.

[0036] For the above steps 21 and 22, the above VIP user and the 1000M wide area network bandwidth have a corresponding relationship, and the ordinary user and the 500M wide area network bandwidth have a corresponding relationship. Figure 2 As shown in the figure, high bandwidth represents 1000M and low bandwidth represents 500M. Based on this, by mapping the services of VIP users to high-bandwidth lines, we can avoid being assigned to low-bandwidth scenarios when participating in the dual WAN connection creation. Therefore, VIP services give priority to using high-bandwidth links. At the same time, the services of ordinary users are mapped to low-bandwidth links, thereby reducing the use of high-bandwidth lines by ordinary users' services. At the same time, low-bandwidth links can also ensure the basic network use of ordinary services.

[0037] In an optional implementation manner of the embodiment of the present application, the preset correspondence in the embodiment of the present application is used to characterize that each wide area network broadband corresponds to one or more types of data to be transmitted. Before obtaining the preset correspondence, the method of the embodiment of the present application may further include:

[0038] Step 31, classify the data to be transmitted and obtain the service type;

[0039] Step 32: Based on the service type, a preset correspondence relationship between different service types and different wide area network bandwidths is established.

[0040] The types of services involved in the above steps 31 and 32 can be set accordingly according to actual needs, for example, the types of services are divided into: web services, video services and voice services. Since different wide area network broadbands in the embodiment of the present application have different bandwidths, the corresponding relationship between different wide area network broadbands can be set based on the actual types of services. For example, if the current voice service has a large demand for bandwidth, and the web services and video services have a smaller demand for bandwidth than the voice service. Based on this, if the two wide area network bandwidths currently pulled are 500M and 1000M, the corresponding relationship between the voice service and the 1000M wide area network broadband is set, and the corresponding relationship between the web services and the video services and the 500M wide area network broadband is set. In actual use, the data corresponding to the voice service is transmitted based on the 1000M bandwidth, and the data corresponding to the web services and the video services are transmitted based on the 500M bandwidth. Of course, the above is just an example. In different application scenarios, the demand for bandwidth of each type of service may be different, and the corresponding relationship between the two needs to be set according to actual needs. In addition, in the embodiment of the present application, more than two bandwidths can be set, for example, a web service, a video service, and a voice service each correspond to one bandwidth.

[0041] In an optional implementation manner of the embodiment of the present application, the method of determining the wide area network bandwidth corresponding to the data to be transmitted based on the preset corresponding relationship involved in the above step 101 may further include:

[0042] Step 41, determining the service type of the data to be transmitted;

[0043] Step 42: Determine the wide area network bandwidth corresponding to the service type based on the preset corresponding relationship.

[0044] For the above steps 41 and 42, the above voice service still has a corresponding relationship with the 1000M wide area network bandwidth, and the web service and video service have a corresponding relationship with the 500M wide area network bandwidth, as shown in the following example. Figure 3 As shown in the figure, high bandwidth represents 1000M, low bandwidth represents 500M, and by mapping voice services to high-bandwidth lines, it is possible to avoid being assigned to low-bandwidth scenarios when creating dual WAN connections. At the same time, ordinary services such as web pages and videos can be mapped to low-bandwidth links, thereby reducing the use of high-bandwidth lines by ordinary services, while low-bandwidth links can also ensure the use of basic networks for ordinary services.

[0045] In an optional implementation manner of the embodiment of the present application, the preset correspondence in the embodiment of the present application is used to characterize the data correspondence between each wide area network broadband and one or more local area network ports. Before obtaining the preset correspondence, the method of the embodiment of the present application may further include:

[0046] Step 51, classifying the LAN port for accessing the router through which the data to be transmitted is accessed, and obtaining the LAN port type;

[0047] Step 52: Based on the LAN port type, a preset correspondence between different LAN port types and different WAN bandwidths is established.

[0048] The LAN port types involved in the above steps 51 and 52 can be set accordingly according to actual needs. For example, if the current number of LAN ports is 3, they are LAN1, LAN2, and LAN3 respectively, then the LAN port types include LAN1, LAN2, and LAN3. Since different WAN broadbands in the embodiment of the present application have different bandwidths, the corresponding relationship between the different WAN broadbands can be set based on the actual LAN port types. For example, if the current bandwidth demand of LAN1 is large, and the bandwidth demand of LAN2 and LAN3 is smaller than that of voice services. Based on this, if the two WAN bandwidths currently pulled are 500M and 1000M, the corresponding relationship between LAN1 and the 1000M WAN broadband is set, and the corresponding relationship between LAN2 and LAN3 and the 500M WAN broadband is set respectively. In actual use, the data transmitted by LAN1 is transmitted based on the 1000M bandwidth, and the data corresponding to LAN2 and LAN3 is transmitted based on the 500M bandwidth. Of course, the above is just an example. In different application scenarios, the bandwidth requirements of the services of each LAN port may be different, and the corresponding relationship between the two needs to be set according to actual needs. In addition, in the embodiment of the present application, more than two broadbands can be set, for example, LAN1, LAN2, and LAN3 each correspond to one broadband.

[0049] In an optional implementation manner of the embodiment of the present application, the method of determining the wide area network bandwidth corresponding to the data to be transmitted based on the preset corresponding relationship involved in the above step 101 may further include:

[0050] Step 61, determining the LAN port type of the LAN port to which the data to be transmitted is connected;

[0051] Step 62: Determine the WAN bandwidth corresponding to the LAN port type based on the preset corresponding relationship.

[0052] For the above steps 61 and 62, it is still assumed that there is a corresponding relationship between the above LAN1 and the 1000M wide area network bandwidth, and there is a corresponding relationship between LAN2 and LAN3 and the 500M wide area network bandwidth respectively. Figure 4 As shown in the figure, high bandwidth represents 1000M and low bandwidth represents 500M. By mapping the LAN port to the high-bandwidth line, it is possible to avoid being assigned to the low-bandwidth scenario when creating a dual WAN connection. Therefore, users connected to the LAN1 port will use the high-bandwidth link with high priority. At the same time, other ports can be mapped to the low-bandwidth link to reduce the use of the high-bandwidth line, while the low-bandwidth link can also ensure its basic network use.

[0053] It can be seen that through the embodiment of the present application, negative balancing at different levels such as port level (such as LAN1, LAN2 and LAN3, etc.), user level (VIP users and ordinary users), and service level (voice service, web service and video service) can be achieved. That is, different data can be directly allocated to the corresponding bandwidth link according to the corresponding relationship, so that the services of the same user all go through the same bandwidth link to ensure the network quality of the same user. In addition, in the embodiment of the present application, the combination of service data at different levels such as port level, user level and service level can also be achieved, for example Figure 5 As shown, user A is set to correspond to broadband A (high bandwidth), user B is set to correspond to broadband B (low bandwidth), voice service corresponds to broadband B, game service corresponds to broadband A, and network port 1 corresponds to broadband A. In other words, the same broadband can correspond to one or more different levels of service data, indicating that multiple different levels of service data can share the same broadband, but in the same broadband, the multiple different levels of service data may or may not have priorities with each other, and can be further set as needed, for example, in the same broadband, the priority of user-level data is higher than that of service-level data, and the priority of service-level data is higher than that of port-level data. The above is just an example, and the priorities of different data can be set according to actual needs.
