Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a network link multiplexing method, device and computer storage medium. Background Art

[0002] Currently, many users' mobile phones or CPE (Customer Premises Equipment) have multiple network connection methods, especially CPE devices usually have 4G / 5G (fourth / fifth generation mobile communication technology) connection, WiFi (wireless network communication technology) connection and wired Ethernet connection. When the user uses it, the CPE device will automatically switch the network according to the quality of the connected network. For example, when the WiFi network jitters abnormally, it will automatically switch to the 4G / 5G network connection.

[0003] However, the disadvantage of this switching method is that the terminal device will only switch to another network when the current network is basically completely unavailable. If the current network is just slow (high latency) and not disconnected, the terminal device will not switch even if the network quality of other optional links is better. In many scenarios, the user's business traffic will be affected by network quality issues, resulting in a poor user experience. Summary of the invention

[0096] The following is an explanation of the terms and related technologies involved in this application:

[0097] CPE (Customer Premises Equipment): CPE refers to communication network equipment installed in the user's residence or office for access to the Internet or other communication services. Common CPEs include routers, modems, network switches, wireless access points and other devices. CPE acts as a bridge between user equipment and network provider equipment, enabling users to enjoy network connection and communication services. CPE can usually use multiple network links such as 4G, 5G, and WiFi.

[0105] Network controller: A hardware device or software program that manages and controls data traffic, connections, and communications in a computer network. It is responsible for observing network communications, enforcing network policies, and optimizing network performance.

[0106] In a computer network, the network controller acts as a central processing unit and has the following functions:

[0112] A network controller can be a part of a network device such as a switch, router, or firewall, or it can be a software program running on a server or operating system. It plays a key role in computer networks, ensuring the normal operation and good performance of the network.

[0113] The following describes several exemplary embodiments to illustrate the technical solutions of the embodiments of the present application and the technical effects produced by the technical solutions of the present application. It should be noted that the following embodiments can refer to, draw on or combine with each other, and the same terms, similar features and similar implementation steps in different embodiments will not be described repeatedly.

[0114] Figure 1 A schematic diagram of the system architecture for implementing a network link multiplexing method provided in an embodiment of the present application, such as Figure 1As shown, the system includes a CPE device, a network controller and a corresponding business website. The CPE device is used by users, and a dedicated SDK and one or more target APPs (applications) are installed therein. These target APPs are APPs in the CPE that are configured with a dedicated SDK. The dedicated SDK can intercept the traffic of these target APPs, that is, all external traffic (including network messages) of these target APPs needs to be forwarded through the SDK. In the embodiment of the present application, the network controller is set in the cloud, and the CPE can be connected to the network controller through multiple network links, such as 4G, 5G or WiFi network links. The network controller can forward the traffic received from the target APP to the business website corresponding to the target APP.

[0115] Specifically, when the target APP in the CPE needs to send a network message to the business website, it can be understood as the "uplink traffic" processing stage. The target APP sends a network message, which is intercepted by the dedicated SDK in the CPE. The dedicated SDK can then forward the intercepted network message to the corresponding network controller through one or more network links. The network controller then sends the received network message to the business website corresponding to the target APP.

[0116] The business website responds to the received network message feedback sent by the target APP. The network message feedback information can be understood as the "downlink traffic" processing stage. The business website corresponding to the target APP will generate network message feedback information in response to the received network message, and send the generated network message feedback information to the corresponding network controller. The network controller can send the received network message feedback information to the CPE's dedicated SDK through one or more network links, and then the dedicated SDK will feedback to the target APP.

[0117] The solution of this application mainly improves the reuse of multiple network links when sending network messages in the "upstream traffic" processing stage, and the reuse of multiple network links when sending network message feedback information in the "downstream traffic" processing stage, thereby realizing efficient reuse of multiple network links in combination with the cloud network controller in the use of CPE. The network link reuse solution will be described in detail below.

[0118] This application involves cloud technology. Cloud technology is a general term for network technology, information technology, integration technology, management platform technology, application technology, etc. based on the cloud computing business model. It can form a resource pool, which is used on demand and is flexible and convenient. Cloud computing technology will become an important support. The background services of the technical network system require a large amount of computing and storage resources, such as video websites, picture websites and more portal websites. With the rapid development and application of the Internet industry, each item may have its own identification mark in the future, and all of them need to be transmitted to the background system for logical processing. Data of different levels will be processed separately, and all kinds of industry data require strong system backing support, which can only be achieved through cloud computing.

[0119] Figure 2 A schematic diagram of a flow chart of a network link multiplexing method provided in an embodiment of the present application, the execution subject of the method may be Figure 1 Dedicated SDK in CPE, such as Figure 2 As shown, the method may include:

[0120] Step S201, when receiving the network message of the target application, the network message is split according to the flow based on the forwarding weight of each network link to obtain the sub-network message corresponding to each network link. The forwarding weight of each network link is determined based on the network quality of the network link.

[0121] As mentioned above, the target application CPE is an application configured with a dedicated SDK, and the network messages sent by these target applications will be intercepted by the dedicated SDK, that is, the dedicated SDK will obtain all traffic generated by each target application. When the user uses the target application, if he needs to access the corresponding business website, the target application will generate a corresponding network message, and then the network message needs to be sent to the corresponding business website to obtain the corresponding network message feedback information.

[0122] Among them, the dedicated SDK is pre-installed on the CPE. In addition to intercepting the traffic of the target application, it can also detect the current network quality of each network link between the CPE and the network controller. Obviously, the dedicated SDK can not only intercept the traffic of the target application, but also detect the network quality of each network link. Only NQA detection is performed to obtain the link quality of each network link. Therefore, the dedicated SDK can use the detected network quality to decide how to reuse each network link.

[0123] Specifically, when any target application in the CPE sends a network message, the dedicated SDK will intercept the network message, and the dedicated CPE needs to forward the network message to the corresponding target network controller in the cloud. In the solution of this application, the dedicated SDK will first determine the forwarding weight of each network link at the current moment, and split the intercepted network message according to the traffic according to the forwarding weight to obtain the sub-network message corresponding to each network link.

[0124] For example, if the traffic size of a network message intercepted by the dedicated SDK is 10M, and it is known in advance that there are three network links that the CPE can support, namely 4G, 5G and WiFi, and the dedicated SDK determines that the forwarding weights corresponding to the current 4G network link, 5G network link and WiFi network link are 0.3, 0.2 and 0.5 respectively, then the dedicated CPE will split the network message according to the traffic based on the forwarding weight to obtain the sub-network message corresponding to each network link. Specifically, the traffic of the sub-network message corresponding to the 4G network link is 3M, the traffic of the sub-network message corresponding to the 5G network link is 2M, and the traffic of the sub-network message corresponding to the WiFi network link is 5M. Then, the dedicated SDK will forward the network message according to the above traffic distribution. Specifically, the dedicated SDK sends the corresponding sub-network message on the 4G network link, that is, sends the corresponding 3M traffic in the network message, the dedicated SDK sends the corresponding sub-network message on the 5G network link, that is, sends the corresponding 2M traffic in the network message, and the dedicated SDK sends the corresponding sub-network message on the WiFi network link, that is, sends the corresponding 5M traffic in the network message. It can be understood that in the embodiment of the present application, the sub-network messages split from the unified network message can be sent on different network links at the same time.

[0125] It should be noted that in the scheme of the embodiment of the present application, when splitting the network message, the data structure of the network message can be analyzed, and the network message can be divided in sequence according to the intrinsic order of the data structure, so as to obtain the sub-network message corresponding to each network link, so as to facilitate the subsequent target network controller to obtain the corresponding network message based on the aggregation of each sub-network message.

[0126] In addition, in the solution of the embodiment of the present application, the forwarding weight of each network link is determined by the current network quality of each network link detected by the dedicated SDK. It can be understood that the determination of the network quality of each network link can be the network quality at the current moment detected by the dedicated SDK, or it can be determined by statistical calculation of the network quality within a time period including the current moment and the historical moment.

[0127] It can be understood that if the network quality corresponding to a network link supported by the CPE indicates that the network link is disconnected, then the traffic of the sub-network message corresponding to the network link is 0, that is, the dedicated SDK does not forward the traffic in the network message through the network link.

[0128] Step S202, sending the corresponding sub-network messages to the target network controller through each network link, so that the target network controller aggregates the sub-network messages to obtain a network message, and sends the network message to the corresponding service website.

[0129] The target network controller is one of the multiple network controllers located in the cloud, and the target network controller can be determined based on the delay between the dedicated SDK in the CPE and each network controller. At the same time, since users may move when using or carrying CPE, the delay between the dedicated SDK in the CPE and each network controller will change. At this time, in order to ensure better network quality, the network controller will be switched, that is, the target network controller will be re-determined.

[0130] Specifically, in the previous step, the dedicated SDK split the intercepted network message, and then determined the sub-network message sent on each network link. In this step, the corresponding sub-network messages will be sent to the target network controller through each network link. After receiving the sub-network messages sent through each network link, the target network controller will aggregate these sub-network messages to obtain a complete network message. The aggregation process can be understood as the reverse process of the aforementioned splitting process, that is, the original network message is restored based on each split sub-network message. Then the original network message is sent to the corresponding business website. At this point, the processing process of "upstream traffic" is completed.

[0131] Continuing with the above example, the dedicated SDK sends the corresponding sub-network message on the 4G network link, that is, sends the corresponding 3M traffic in the network message, the dedicated SDK sends the corresponding sub-network message on the 5G network link, that is, sends the corresponding 2M traffic in the network message, and the dedicated SDK sends the corresponding sub-network message on the WiFi network link, that is, sends the corresponding 5M traffic in the network message. The target network controller receives the above sub-network messages and aggregates them to obtain the original network message of 10M. Specifically, each sub-network message can be aggregated according to the split order of each sub-network message to obtain the corresponding original network message. Then the original network message is sent to the corresponding business website.

[0132] The solution provided by the present application, when receiving the network message of the target application, will first divide the network message according to the flow based on the forwarding weight of each network link supported by the CPE, and obtain the sub-network message of the corresponding flow that needs to be sent on each network link. Then, the sub-network messages of the corresponding flow are forwarded to the target network controller through each network link respectively, so that after receiving each sub-network message, the target network controller aggregates each sub-network message to obtain the original network message sent by the target application, and sends the original network message to the business website corresponding to the target application. The solution splits the network message by the forwarding weight of each network link determined based on the quality of each network, so that different types of network links can be fully utilized in the process of sending the network message of the target application, which maximizes the network connection performance and reliability and improves the user experience.

[0133] In an optional embodiment of the present application, the method may further include:

[0134] The network quality of each network link is obtained at intervals of a second preset period.

[0135] Specifically, the dedicated SDK in the CPE can periodically detect the network quality of each network link, for example, once every 3 minutes. Then, in the solution of the embodiment of the present application, the forwarding weight of each network link will be determined based on the network quality of the most recent detection.

[0136] The specific duration of the second preset period can be set according to actual needs.

[0137] In an optional embodiment of the present application, the higher the network quality of the network link, the greater the corresponding forwarding weight.

[0138] Specifically, the higher the network quality of a network link, the faster the network messages are sent through it, and the better the user experience. Therefore, a network link with high network quality can send more traffic. Therefore, the higher the network quality of the network link, the greater the corresponding forwarding weight can be set to ensure the performance of the network connection.

[0139] In summary, if Figure 3 As shown, the process of sending a network message from a target application in a CPE to a corresponding service website in an embodiment of the present application may include the following steps:

[0140] (1) Install a dedicated SDK on the user's CPE and configure which APPs (applications) forward network messages through the SDK, that is, configure a dedicated ADK for the target APP. The reason for configuration is that only some APPs are suitable for network transmission through the split-first-and-aggregate method of this solution, while other APPs use a special transmission protocol with the business website and cannot be split.

[0141] (2) After the dedicated SDK is installed, it will automatically detect the network links on the current CPE, and then periodically perform NQA detection on each network link, and calculate the forwarding weight of each link based on the detection results of each network link. The higher the quality of the network link detected by NQA (such as low packet loss rate, low latency, and small jitter), the higher the forwarding weight assigned to it, and more traffic will be forwarded through it when forwarding network packets.

[0142] (3) When the target user APP sends an uplink network message (i.e., when sending a network message to the corresponding business website), the network message will pass through the dedicated SDK. The dedicated SDK will distribute the traffic to different network links according to the forwarding weight and forward the network to the target network controller deployed in the cloud.

[0143] (4) After receiving the sub-network messages from different network links, the target network controller can re-aggregate the sub-network messages according to the time sequence of the sub-network messages, and then forward the original messages to the corresponding service website.

[0144] In an optional embodiment of the present application, the method may further include:

[0145] Receive the corresponding sub-network message feedback information sent by the target network controller through each network link. Each sub-network message feedback information is obtained by the target network controller by splitting the network message feedback information according to the traffic based on the forwarding weight of each network link. The network message feedback information is sent to the target network controller by the business website in response to the network message.

[0146] Specifically, in the cloud, the target network controller will send the aggregated original network message to the corresponding business website, and the business website will respond to the network message and feedback the corresponding network message information to the target network controller. Then, the target network controller will send the network message feedback information to the dedicated SDK in the CPE, and the dedicated SDK will send it to the target application. In the process of the target network controller sending the network message feedback information to the dedicated SDK in the CPE, each network link can also be reused according to the forwarding right of each network link, that is, the network message feedback information is split according to the traffic based on the forwarding weight of each network link. At this time, the forwarding weight used is the forwarding weight used when splitting the network message in the corresponding "uplink traffic" processing stage. The target network controller can determine the size of the corresponding forwarding weight according to the traffic size of the sub-network message received from different network links.

[0147] Specifically, the traffic flowing down from the cloud will first reach the target network controller, and then be forwarded to the dedicated SDK by the target network controller. When receiving the uplink traffic, the target network controller will record the proportion of traffic sent through each network link, for example: WiFi, mobile network, and wired network account for 30%, 50%, and 20% respectively, and the network distribution will also be carried out according to this proportion when forwarding the downlink traffic. Since the dedicated SDK on the CPE periodically detects the network quality of each network link and adjusts the proportion of each network link in real time, the cloud controller does not need to perform network detection anymore, and can directly forward the downlink traffic according to the uplink sending strategy.

[0148] In an optional embodiment of the present application, the method may further include:

[0149] Send a registration request to the dedicated software development kit SDK registration center;

[0150] Receive the token and network controller address list sent by the SDK registration center after the registration request is verified;

[0151] Obtaining the target delay corresponding to each network controller in the network controller address list at intervals of a first preset period, where the target delay is the network delay between the dedicated SDK and each network controller;

[0152] Send the corresponding sub-network message to the target network controller through each network link, including:

[0153] determining a target network controller from among the network controllers based on the target delays;

[0154] Each network link between the target network controller and the target network controller is established through the token, and the corresponding sub-network message is sent to the target network controller through each network link.

[0155] Specifically, after users purchase network aggregation services from cloud vendors, they can download the corresponding dedicated SDK from the website to start using it. In order to prevent the dedicated SDK from being maliciously misused, registration is required when the dedicated SDK goes online. First, you need to register at the dedicated SDK registration center. Only after verification is passed can the dedicated SDK establish a network connection with the network controller.

[0156] Specifically, if Figure 4 As shown, the registration process may include the following steps:

[0157] (1) Users purchase services from cloud vendors, download and install the dedicated SDK on the CPE, and log in with their account and password.

[0158] (2) When the dedicated SDK goes online for the first time, it will carry the account and password to initiate registration with the dedicated SDK registration center in the cloud. After receiving the request number, the registration center will first verify the account and password. After the verification is successful, a token will be generated based on the user name, the unique ID (identification information) of the dedicated SDK, and the timestamp.

[0159] (3) The dedicated SDK registration center then feeds back the network controller address list and token to the dedicated SDK, and notifies the network controller of the dedicated SDK's account and token. The SDK can only connect after the network controller records them.

[0160] (4) Finally, the dedicated SDK uses the account and token to establish a network connection with the network controller.

[0161] After the dedicated SDK registration is completed, Figure 5 As shown, the target delay between each network controller and the dedicated SDK can be detected according to the acquired network controller address list. Then, the target network controller can be determined according to the detected target delay.

[0162] In an optional embodiment of the present application, determining a target network controller from each network controller based on each delay includes:

[0163] If it is the first time to determine the target network controller, the network controller with the smallest corresponding target delay among the network controllers is determined as the target network controller;

[0164] If it is not the first time to determine the target network controller, the network controller with the smallest corresponding target delay among the network controllers is determined as the candidate network controller, and the candidate network controller or the network controller currently connected to the dedicated SDK is determined as the target controller.

[0165] Specifically, in order to be able to forward the network messages to the business website in the shortest path after aggregating the network messages, the network controller in the solution of the embodiment of the present application will also adopt a multi-region distributed deployment, and a real network controller instance will be deployed in each core area. Therefore, the dedicated SDK needs to select the most suitable network controller as the target network controller when connecting to the network controller. Since the SDK is deployed on the user side, the user may move with the CPE. When the SDK successfully registers with the registration center, the dedicated SDK registration center will return the addresses of all currently available network controllers to the dedicated SDK, and the dedicated SDK will decide on its own to connect to the network controller, that is, the dedicated SDK will determine which network controller is the target network controller.

[0166] After receiving the network controller address list returned by the dedicated SDK registration center, the dedicated SDK will start a thread in the background to periodically detect the connectivity and network latency of each network controller, that is, to obtain the target latency between each network controller. After each detection, the dedicated SDK will save the target latency data of each network controller in the cache. When a network message needs to be sent, it will query the cache for the network controller with the smallest target latency as the target network controller for sending. When the dedicated SDK switches the target network controller node to be connected, in order to prevent message loss, it has to suspend traffic transmission until the previous wave of messages has been successfully aggregated at the previous node before switching to the new node.

[0167] In order to prevent unnecessary business losses caused by frequent ping-pong switching of user CPE in critical areas, the period of the background detection thread of the dedicated SDK should be set longer. In this way, even if the connection fails to switch in time due to the movement of the user's location, it will only cause a short-term increase in delay, which is negligible compared to the loss of business traffic suspension during switching.

[0168] In an optional embodiment of the present application, determining the candidate network controller or the network controller to which the dedicated SDK is currently connected as the target controller includes:

[0169] If the target time interval corresponding to the candidate network controller is not less than the first preset value, determining the candidate network controller as the target network controller;

[0170] If the target time interval is less than the first preset value, determining the network controller to which the dedicated SDK is currently connected as the target controller;

[0171] The target time interval is the time interval between the last time the dedicated SDK was connected to the candidate network controller and the current time.

[0172] Specifically, ping-pong switching can be prevented by determining the target network controller in the above manner.

[0173] Specifically, under the guidance of the above ideas, there can be another way to prevent ping-pong switching, which is to record the cache of the connection time on the dedicated SDK of the CPE, and build a network controller connection time list, which records the connection time of each network controller's most recent connection with the dedicated SDK, as shown in Table 1 below:

[0174] Table 1

[0175] Network Controller Node Last connection time (Unix timestamp) Node-1 1680693202 Node-2 1680691202 Node-3 1680693102

[0176] When the dedicated SDK is connected to a network controller, the ID and connection time of the controller node will be recorded in the memory, that is, a network controller connection time list will be built in the cache. When the dedicated SDK continues to connect to the network controller node, the most recent connection time in the network controller connection time list will be refreshed periodically (for example, every 30 seconds). At the same time, a timer will be started in the dedicated SDK to refresh the network controller connection time list every 10 seconds. When refreshing, all controller node information in the cache is read. If the most recent connection time exceeds the threshold (for example, 30 minutes), it means that the last connection to the controller node was 30 minutes ago, and it will be deleted from the network controller connection time list. When the user's CPE moves in space and the dedicated SDK wants to switch to another network controller, it will first query the network controller connection time list information. If the controller node to be connected exists in the cache and the most recent connection time is less than 5 minutes, the switch will not be performed. The background thread will continue to detect the latency of the connectable network controller node. If the new node is always in a switchable state, it will be switched after 5 minutes. This can avoid ping-pong switching when the user CPE moves back and forth between the boundaries of two areas.

[0177] Figure 6 A flowchart of another network link multiplexing method provided in an embodiment of the present application, the execution subject of the method may be Figure 1 The target network controller in Figure 6 As shown, the method may include:

[0178] Step S601, receiving the corresponding sub-network message sent by the dedicated software development kit SDK through each network link.

[0179] Step S602: Aggregate the sub-network messages to obtain corresponding network messages, and send the network messages to the corresponding service website.

[0180] Among them, the sub-network message corresponding to each network link is obtained by the dedicated SDK when receiving the network message of the target application, splitting the network message according to the traffic based on the forwarding weight of each network link, and the forwarding weight of each network link is determined based on the network quality of the network link.

[0181] Specifically, when any target application in the CPE sends a network message, the dedicated SDK will intercept the network message, and the dedicated CPE needs to forward the network message to the corresponding target network controller in the cloud. In the solution of this application, the dedicated SDK will first determine the forwarding weight of each network link at the current moment, and split the intercepted network message according to the traffic according to the forwarding weight to obtain the sub-network message corresponding to each network link.

[0182] The dedicated SDK splits the intercepted network message and determines the sub-network message sent on each network link. In this step, the corresponding sub-network messages will be sent to the target network controller through each network link. After receiving the sub-network messages sent through each network link, the target network controller will aggregate these sub-network messages to obtain a complete network message. The aggregation process can be understood as the reverse process of the aforementioned splitting process, that is, the original network message is restored based on each split sub-network message. The original network message is then sent to the corresponding business website. At this point, the "upstream traffic" processing process is completed.

[0183] The solution provided by the present application, when receiving the network message of the target application, will first divide the network message according to the flow based on the forwarding weight of each network link supported by the CPE, and obtain the sub-network message of the corresponding flow that needs to be sent on each network link. Then, the sub-network messages of the corresponding flow are forwarded to the target network controller through each network link respectively, so that after receiving each sub-network message, the target network controller aggregates each sub-network message to obtain the original network message sent by the target application, and sends the original network message to the business website corresponding to the target application. The solution splits the network message by the forwarding weight of each network link determined based on the quality of each network, so that different types of network links can be fully utilized in the process of sending the network message of the target application, which maximizes the network connection performance and reliability and improves the user experience.

[0184] In an optional embodiment of the present application, the method further includes:

[0185] Receiving network message feedback information sent by the service website in response to the network message;

[0186] Based on the forwarding weight of each network link, the network message feedback information is split according to the flow rate to obtain the sub-network message feedback information corresponding to each network link;

[0187] The corresponding sub-network message is sent to the dedicated SDK through each network link.

[0188] Specifically, in the cloud, the target network controller will send the aggregated original network message to the corresponding business website, and the business website will respond to the network message and feedback the corresponding network message information to the target network controller. Then, the target network controller will send the network message feedback information to the dedicated SDK in the CPE, and the dedicated SDK will send it to the target application. In the process of the target network controller sending the network message feedback information to the dedicated SDK in the CPE, each network link can also be reused according to the forwarding right of each network link, that is, the network message feedback information is split according to the traffic based on the forwarding weight of each network link. At this time, the forwarding weight used is the forwarding weight used when splitting the network message in the corresponding "uplink traffic" processing stage. The target network controller can determine the size of the corresponding forwarding weight according to the traffic size of the sub-network message received from different network links.

[0189] Specifically, the traffic flowing down from the cloud will first reach the target network controller, and then be forwarded to the dedicated SDK by the target network controller. When receiving the uplink traffic, the target network controller will record the proportion of traffic sent through each network link, for example: WiFi, mobile network, and wired network account for 30%, 50%, and 20% respectively, and the network distribution will also be carried out according to this proportion when forwarding the downlink traffic. Since the dedicated SDK on the CPE periodically detects the network quality of each network link and adjusts the proportion of each network link in real time, the cloud controller does not need to perform network detection anymore, and can directly forward the downlink traffic according to the uplink sending strategy.

[0190] In an optional embodiment of the present application, sending the network message to the corresponding service website includes:

[0191] The network message is sent to the corresponding business website through the dedicated line link between the forwarding gateway corresponding to the target network controller and the forwarding gateway corresponding to the business website.

[0192] Further, the network message is sent to the corresponding business website through a dedicated link between the forwarding gateway corresponding to the target network controller and the forwarding gateway corresponding to the business website, including:

[0193] If the dedicated line link is a third-party dedicated line link, the network message is sent to the corresponding business website through a preset encrypted tunnel on the third-party dedicated line link.

[0194] Specifically, the above solution can speed up the transmission of CPE network traffic to the cloud, and then the network traffic is forwarded from the cloud to the business website through the public network link. Some users have high requirements for network quality (usually higher requirements for network security) and hope to speed up network transmission as much as possible. In the cloud transmission section, consider using dedicated links instead of ordinary public network links for transmission.

[0195] like Figure 7 As shown in the figure, when the network controller in city A transmits data to the business-2 website in city C, the data can be transmitted through the dedicated link between the two cities. The user ID of the VIP user (configured through the SDK) needs to be configured on the forwarding gateway. When the business traffic reaches the forwarding gateway, the gateway identifies the traffic of the VIP user and forwards it through the dedicated link. The dedicated link not only has a fast transmission rate, but also has extremely high security due to its dedicated characteristics and isolation of external traffic.

[0196] However, some cities do not have dedicated lines between them. To ensure the traffic security of VIP users, they can only go through areas with dedicated lines. Figure 7 As shown in the figure, when the traffic from city A is forwarded to city B, since there is no direct dedicated line, it needs to take a detour through city C, which undoubtedly increases the network latency. In this scenario, traffic can be forwarded with the help of a third-party dedicated line link between city A and city B. The third-party dedicated line link may be used by multiple business parties at the same time, and cannot guarantee security like a self-built dedicated line. Here, an encrypted tunnel is established between forwarding gateways for transmission. Configure the user ID to be accelerated in advance on the forwarding gateway, create a dedicated IPSEC (Internet Protocol Security) encrypted tunnel for each user, and when the user traffic reaches the forwarding gateway, it is forwarded to the corresponding IPSEC tunnel according to the user ID.

[0197] It should be noted that the above cities A, B, and C are merely illustrative and may be replaced by any other different locations.

[0198] Figure 8 A structural block diagram of another network link multiplexing device provided in an embodiment of the present application, such as Figure 8 As shown, the device 800 may include: a network message splitting module 801 and a first network message sending module 802, wherein:

[0200] The first network message sending module 802 is used to send the corresponding sub-network message to the target network controller through each network link, so that the target network controller can aggregate the sub-network messages to obtain the network message and send the network message to the corresponding service website.
