[0035] As described in the background technology, because the TCP protocol needs to be implemented in the kernel, the kernel must be upgraded to achieve aggregation; in addition, MPTCP also relies on the cooperation and support of the server, which is difficult to implement in actual applications.

[0036] In the technical solution of the present invention, the request of the application layer protocol is distributed to multiple available transmission links, and the above network requests are sent in parallel through multiple available transmission links, thereby achieving the effect of multi-link concurrency and multi-link aggregation of business data. In addition, since the application layer protocol supports the splitting and reorganization of data, it does not need to rely on the support of the server; and the solution of the present invention is implemented at the application layer and does not need to rely on the kernel system, thereby reducing the complexity of multi-link transmission implementation and helping to expand the scope of application.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] Figure 1 The present invention is a flowchart of a multi-link transmission method according to an embodiment of the present invention.

[0039] The multi-link transmission method of the embodiment of the present invention can be used on the terminal device side, that is, the various steps of the above method can be performed by the terminal device. The terminal device can be various appropriate devices such as a mobile phone and a computer. More specifically, the various steps of the multi-link transmission method can be performed by a computer program in the terminal device.

[0040] Specifically, the multi-link transmission method may include the following steps:

[0041] Step 101: Obtain a network request, where the network request is a request of an application layer protocol;

[0042] Step 102: Allocate the network request to a plurality of available transmission links, so as to transmit the network request using the plurality of available transmission links.

[0043] It should be pointed out that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0044] It is understandable that, in a specific implementation, the multi-link transmission method can be implemented in the form of a software program, which runs in a processor integrated inside a chip or a chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0045] The application layer protocol in this embodiment defines how application processes running on different end systems transmit messages to each other.

[0046] In a specific implementation, the network request can be a Hyper Text Transfer Protocol (HTTP) request, a File Transfer Protocol (FTP) request, a Domain Name System (DNS) request, a Simple Network Management Protocol (SNMP) request, a Telnet request, etc.

[0047] It is understandable that in a specific application scenario, multi-link transmission may be performed on different application layer protocol requests according to actual application requirements, which will not be described in detail here.

[0048] In the specific implementation of step 101, the network request may come from an application (Application, APP) in the terminal device. The application may generate the network request to request network resources.

[0049] Furthermore, in the specific implementation of step 102, the network request can be allocated to multiple transmission links for transmission. Among them, the multiple available transmission links are selected from multiple types of links, such as wireless network (Wi-Fi), cellular network (Cellular), Ethernet (Ethernet), etc. The embodiment of the present invention utilizes multiple transmission links to achieve parallel transmission of network requests and improve transmission efficiency.

[0050] In a specific implementation, when there are multiple network requests, the multiple network requests may be respectively allocated to multiple transmission links.

[0051] In another specific implementation, when the number of network requests is single, the single network request may be split into multiple sub-network requests, and then the multiple sub-network requests are respectively allocated to multiple transmission links.

[0052] In the embodiment of the present invention, the request of the application layer protocol is distributed to multiple available transmission links, and the above network request is sent in parallel through multiple available transmission links, thereby achieving the effect of multi-link concurrency and multi-link aggregation of business data. In addition, since the application layer protocol supports the splitting and reorganization of data, it does not need to rely on the support of the server; and the solution of the present invention is implemented at the application layer and does not need to rely on the kernel system, thereby reducing the complexity of multi-link transmission implementation and helping to expand the scope of application.

[0053] In a specific embodiment, when a network request for a device is sent to a server through a multi-link transmission method, since the port of the terminal device is the outlet for the device to communicate with the outside world, the embodiment of the present invention can also realize multi-port transmission.

[0054] In a non-limiting example, see Figure 2 , the multi-link transmission method may include steps 201 to 205.

[0055] In step 201, a network request is obtained, where the network request is a request of an application layer protocol, and the number of the network request is one or more.

[0056] In step 202, link qualities of a plurality of available transmission links are estimated.

[0057] In a specific implementation, the link quality of multiple available transmission links can be estimated to determine the link quality of each transmission link. Specifically, the link quality of the transmission link can be estimated based on parameters such as the packet loss rate and signal-to-noise ratio of the transmission link.

[0058] Specifically, the link quality of multiple available transmission links can be estimated to determine the link quality of each transmission link. Specifically, the link quality of the transmission link can be estimated based on parameters such as the packet loss rate and signal-to-noise ratio of the transmission link.

[0059] It should be noted that, for the specific implementation of estimating link quality, reference may be made to the prior art and will not be repeated here.

[0060] In step 203, multiple network requests are allocated to the multiple available transmission links according to the link quality, or the network request is split into multiple sub-network requests and the multiple sub-network requests are allocated to the multiple available transmission links, so as to transmit the multiple network requests or the multiple sub-network requests using the multiple available transmission links.

[0061] In a specific implementation, when multiple network requests are respectively allocated to multiple transmission links, if the number of network requests is equal to the number of transmission links, one transmission link can be allocated to each network request; if the number of network requests is greater than the number of transmission links, the network requests can be placed in a cache queue, and a transmission link can be allocated to each network request in sequence according to the queue order; if the number of network requests is less than the number of transmission links, a transmission link with better link quality can be selected, and multiple network requests can be allocated to the multiple selected transmission links.

[0062] In another specific implementation, when the number of network requests is single, the network request can be split according to the number of transmission links, that is, the number of sub-network requests obtained by splitting is the same as the number of transmission links. After the splitting is completed, a transmission link is allocated to each sub-network request.

[0063] In another specific implementation, if the number of network requests is less than the number of transmission links, some network requests may be split so that the sum of the number of split sub-network requests and the number of unsplit network requests is equal to the number of transmission links. For example, there are currently two network requests, network request 1 and network request 2; and there are three transmission links, link 1, link 2, and link 3; at this time, network request 1 may be split into sub-network request A and sub-network request B, and sub-network request A, sub-network request B, and network request 2 may be allocated to the above three transmission links.

[0064] In step 204, response messages to the multiple network requests or the multiple sub-network requests are received on the multiple available transmission links respectively.

[0065] In this embodiment, since multiple network requests or multiple sub-network requests are sent through multiple transmission links respectively, and the server will feedback corresponding response messages, and multiple response messages are also transmitted through multiple transmission links respectively, the terminal device can receive corresponding response messages on multiple transmission links.

[0066] Furthermore, the multi-link transmission method may further include step 205: after receiving the response messages of the multiple sub-network requests, sorting the response messages of the multiple sub-network requests according to the order of the multiple sub-network requests, and feeding back the multiple response messages in order.

[0067] In this embodiment, since the sub-network request is obtained by splitting a network request, the response message of the sub-network request is also for the sub-network request. In order to ensure the validity of the response message, the response messages of multiple sub-network requests need to be sorted and combined. For example, when the network resource requested by the network request is a picture or a file, the response message returned by the server is a part of the picture. In order to ensure the validity of the response message, each response message can be combined in order.

[0068] In a specific implementation, when the response messages are sorted, they can be sorted in the order of multiple sub-network requests. This is because after the network request is split, each sub-network request has an order. For example, after the HTTP request is split, sub-HTTP request 1, sub-HTTP request 2, and sub-HTTP request 3 can be obtained; then after receiving the response messages for sub-HTTP request 1, sub-HTTP request 2, and sub-HTTP request 3, each response message is combined in the corresponding order.

[0069] In a specific implementation, feeding back a plurality of response messages in sequence may refer to feeding back a plurality of response messages to a source application (ie, an application generating a network request) as required.

[0070] In a non-limiting embodiment, the following steps may also be included before step 102: when the number of acquired network requests is one, estimating a first duration taken to transmit the network request using a single transmission link; splitting the network request into multiple sub-network requests, and estimating a second duration taken to transmit the multiple sub-network requests using the multiple available transmission links.

[0071] In this embodiment, since the splitting of the network request and the subsequent assembly of the response message need to be divided into time lengths, in order to ensure transmission efficiency, before the splitting, the benefits generated after the splitting into sub-network requests for multi-link transmission can be predicted. Specifically, the first time length spent on transmitting the network request using a single transmission link can be estimated, and the second time length spent on transmitting multiple sub-network requests using multiple available transmission links can be estimated.

[0072] Furthermore, if the second duration is less than the first duration, a network request is split into multiple sub-network requests. That is to say, only when the second duration is less than the first duration, it indicates that the transmission efficiency of multi-link transmission is higher, which means that the size of the network resources requested by the network request is faster than the single link transmission after the multi-link transmission is performed according to the current link quality slices, and then the network request can be split.

[0073] In a non-limiting embodiment, step 102 may include the following steps: determining the transmission link that matches each network request or sub-network request according to the degree of matching between the size of the network request or the size of the sub-network request and the link quality of the multiple available transmission links, the better the quality of the transmission link, the larger the storage resources occupied by the network request or sub-network request corresponding to the transmission link.

[0074] In this embodiment, when allocating multiple network requests or the sub-network requests to multiple transmission links, the principle of allocation is that the better the link quality of the transmission link, the larger the storage resources occupied by the network request or sub-network request allocated on the link. For example, the size of sub-HTTP request 1 is 10M, the size of sub-HTTP request 2 is 5M, and the size of sub-HTTP request 3 is 8M. The link quality from good to bad is link 1, link 2, and link 3, then sub-HTTP request 1 can be allocated to link 1, sub-HTTP request 2 can be allocated to link 3, and sub-HTTP request 3 can be allocated to link 2.

[0075] In a non-limiting embodiment, the link qualities of the plurality of available transmission links are estimated using a neural network model, which may be pre-built and trained.

[0076] In a specific implementation, link parameters (such as packet loss rate, signal-to-noise ratio, delay, etc.) used to evaluate link quality can be input into a neural network model, and the neural network model can output the link quality of the transmission link.

[0077] Furthermore, when training the neural network model, training samples may be collected first, the training samples including various link parameters used to evaluate link quality and link quality values, and the neural network model may be trained using the training samples.

[0078] In a specific application scenario, please refer to Figure 3 , the application 301 initiates an HTTP request 302, and the prediction and assembly module 303 first performs a benefit prediction. If the size of the network resources requested by the HTTP request 302 is predicted to be faster than a single link after multi-link transmission after sharding based on the current link quality prediction, the prediction and assembly module 303 will fragment the HTTP request 302 and output the relevant information of the task to the allocation module 304. The allocation module 304 determines which link the task is sent from based on the task information and the link quality estimated by the link quality estimation module 305. The allocation module 304 then allocates different requests to different links according to the link allocation algorithm, thereby deriving multiple sub-Http requests. Multiple sub-Http requests will generate multiple response messages, and the prediction and assembly module 303 will then cache and sort the returned response messages and return them to the application 301. The entire process is transparent to the application and the underlying layer. Since it is based on the HTTP standard, it can be implemented without the support of the server.

[0079] The embodiment of the present invention firstly fragments HTTP requests based on the application layer HTTP protocol, and allocates different fragments to different transmission links, so that the network services of the application program can be multi-link concurrent, thereby superimposing and improving the bandwidth, and it can be completed without relying on the cooperation of the service.

[0080] In another specific application scenario, the application 301 simultaneously initiates multiple HTTP requests 302, and the pre-judgment and assembly module 303 directly provides the relevant information of the multiple HTTP requests 302 to the allocation module 304. The allocation module 304 allocates the multiple HTTP requests 302 to different links according to the link allocation algorithm. Compared with the previous application scenario, the pre-judgment and assembly module 303 in this application scenario does not need to fragment the HTTP requests, and the response data does not need to be cached and sorted, and can be directly returned to the application 301.

[0081] For example, in the application scenario of browsing web pages with a browser, a web page contains many sub-resources, and requests for different resources are dynamically allocated according to the link allocation algorithm, thereby achieving the effect of multi-link concurrency and multi-link aggregation of business data.

[0082] It should be noted that the HTTP request 302 may also be replaced by any other feasible application layer protocol request, and the embodiment of the present invention does not limit this.

[0087] Furthermore, the transmission allocation module allocates the multiple network requests to the multiple available transmission links.

[0088] Furthermore, the transmission allocation module splits the network request into multiple sub-network requests and allocates the multiple sub-network requests to the multiple available transmission links.
