Detailed Description
As described in the background, because the TCP protocol needs to be implemented in the kernel, the kernel is upgraded to implement aggregation; in addition, MPTCP also depends on the cooperative support of the server, and is difficult to implement in practical application.
In the technical scheme of the invention, the request of the application layer protocol is distributed to a plurality of available transmission links, and the network request is sent in parallel through the plurality of available transmission links, thereby realizing the effect of multilink concurrence and service data multilink aggregation. In addition, because the application layer protocol supports the splitting and the recombination of data, the support of a server is not required to be relied on; moreover, the scheme of the invention is realized in an application layer without depending on a kernel system, thereby reducing the complexity of realizing multilink transmission and being beneficial to expanding the application range.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flowchart of a multilink transmission method according to an embodiment of the present invention.
The multilink transmission method of the embodiment of the invention can be used for the terminal equipment side, namely, the terminal equipment can execute the steps of the method. The terminal equipment can be various appropriate equipment such as a mobile phone, a computer and the like. More specifically, the various steps of the multi-link transmission method may be performed by a computer program in the terminal device.
Specifically, the multilink transmission method may include the steps of:
step 101: acquiring a network request, wherein the network request is a request of an application layer protocol;
step 102: the network request is assigned to a plurality of available transmission links for transmission of the network request using the plurality of available transmission links.
It should be noted that the sequence numbers of the steps in this embodiment do not represent a limitation on the execution sequence of the steps.
It will be appreciated that in a specific implementation, the multilink transmission method may be implemented by a software program running on a processor integrated within a chip or a chip module. The method may also be implemented by combining software and hardware, and the present application is not limited thereto.
The application layer protocol (application layer protocol) in this embodiment defines how application processes running on different end systems transfer messages with each other.
In a specific implementation, the Network request may be a hypertext 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 Protocol (Telnet) request, or the like.
It can be understood that in a specific application scenario, multilink transmission may be performed for different application layer protocol requests according to actual application requirements, and details are not repeated here.
In the specific implementation of step 101, the network request may come from an Application (APP) in the terminal device. The application may generate the network request for requesting network resources.
Further, in the implementation of step 102, the network request can be distributed to a plurality of transmission links for transmission. Wherein the plurality of available transmission links are selected from a plurality of types of links, such as wireless networks (Wi-Fi), Cellular networks (Cellular), Ethernet (Ethernet), and the like. The embodiment of the invention can realize the parallel sending of the network request by utilizing a plurality of transmission links, thereby improving the sending efficiency.
In one embodiment, when the number of the network requests is multiple, the multiple network requests may be respectively allocated to the multiple transmission links.
In another specific embodiment, when the number of the network requests is single, the single network request may be split to obtain a plurality of sub-network requests, and then the plurality of sub-network requests are respectively allocated to the plurality of transmission links.
In the embodiment of the invention, the request of the application layer protocol is distributed to a plurality of available transmission links, and the network request is sent in parallel through the plurality of available transmission links, so that the effects of multilink concurrence and multilink aggregation of service data are realized. In addition, because the application layer protocol supports the splitting and the recombination of data, the support of a server is not required to be relied on; moreover, the scheme of the invention is realized in an application layer without depending on a kernel system, thereby reducing the complexity of realizing multilink transmission and being beneficial to expanding the application range.
In a specific embodiment, when the network request for the device is sent to the server by using the multilink transmission method, the embodiment of the present invention may also implement multiport transmission because the port of the terminal device is an outlet for communication between the device and the outside.
In a non-limiting embodiment, referring to fig. 2, the method for multi-link transmission may include steps 201 to 205.
In step 201, network requests are obtained, where the network requests are requests of an application layer protocol, and the number of the network requests is one or more.
In step 202, link qualities of a plurality of available transmission links are estimated.
In a specific implementation, link qualities of a plurality of 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 according to parameters such as a packet loss rate and a signal-to-noise ratio of the transmission link.
In particular, link qualities of a plurality of available transmission links may be estimated to determine the link quality of each transmission link. Specifically, the link quality of the transmission link can be estimated according to parameters such as a packet loss rate and a signal-to-noise ratio of the transmission link.
It should be noted that, regarding the specific implementation of estimating the link quality, reference may be made to the prior art, and details are not described herein.
In step 203, a plurality of network requests are allocated to the plurality of available transmission links according to the link quality, or the network requests are split into a plurality of sub-network requests and allocated to the plurality of available transmission links, so as to transmit the plurality of network requests or the plurality of sub-network requests by using the plurality of available transmission links.
In one embodiment, in the case that a plurality of network requests are respectively allocated to a plurality of transmission links, if the number of network requests is equal to the number of transmission links, one transmission link may be allocated to each network request; if the number of the network requests is larger than that of the transmission links, the network requests can be placed into a buffer queue, and the transmission links are sequentially distributed to the network requests according to the queue sequence; 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 a plurality of network requests can be distributed to the plurality of selected transmission links.
In another specific embodiment, when the number of the network requests is single, the network requests may be split according to the number of the transmission links, that is, the number of the split sub-network requests is the same as the number of the transmission links. After the splitting is completed, a transmission link is allocated to each sub-network request.
In yet another embodiment, if the number of network requests is less than the number of transmission links, the partial network requests may be split such that the sum of the number of split sub-network requests and the number of non-split network requests equals 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, the network request 1 can be split into a sub-network request a and a sub-network request B, and the sub-network request a, the sub-network request B, and the network request 2 are distributed to the three transmission links.
In step 204, response messages for the plurality of network requests or the plurality of sub-network requests are received at the plurality of available transmission links, respectively.
In this embodiment, since the plurality of network requests or the plurality of sub-network requests are respectively sent through the plurality of transmission links, the server feeds back corresponding response messages, and the plurality of response messages are also respectively transmitted through the plurality of transmission links, the terminal device may receive corresponding response messages over the plurality of transmission links.
Further, the multilink transmission method may further include step 205: after receiving the response messages requested by the sub-networks, sequencing the response messages requested by the sub-networks according to the sequence requested by the sub-networks, and feeding back the response messages in sequence.
In this embodiment, because the sub-network request is obtained by splitting one network request, and 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, and in order to ensure the validity of the response message, the response messages may be combined in sequence.
In particular implementations, when sorting the response messages, they may be sorted in the order of the plurality of sub-network requests. This is because there is an order between the sub-network requests after splitting the network request. For example, after splitting the HTTP request, a sub HTTP request 1, a sub HTTP request 2, and a sub HTTP request 3 may be obtained; then after receiving the response messages for sub HTTP request 1, sub HTTP request 2 and sub HTTP request 3, the respective response messages are combined in a corresponding order.
In a specific implementation, feeding back multiple response messages in sequence may refer to feeding back multiple response messages to a source application (i.e., an application that generates a network request) as needed.
In one non-limiting embodiment, step 102 may be preceded by the steps of: when the number of the obtained network requests is one, estimating a first time spent on transmitting the network requests by using a single transmission link; the network request is split into a plurality of sub-network requests, and a second time duration spent transmitting the plurality of sub-network requests using the plurality of available transmission links is estimated.
In this embodiment, since the splitting of the network request and the subsequent assembly of the response message require time division, in order to ensure transmission efficiency, the benefit generated after the splitting of the sub-network request and the multilink transmission can be pre-determined before the splitting. In particular, a first time period taken to transmit a network request over a single transmission link may be estimated, and a second time period taken to transmit a plurality of sub-network requests over a plurality of available transmission links may be estimated.
Further, if the second duration is less than the first duration, splitting a network request into a plurality of sub-network requests. That is, only when the second duration is less than the first duration, it indicates that the transmission efficiency of the multilink transmission is higher, that is, the size of the network resource requested by the network request is faster than that of a single link transmission after being fragmented according to the quality of each link at present, and then the network request can be split.
In one non-limiting embodiment, step 102 may include the steps of: and determining the transmission link matched with each network request or the sub-network request according to the matching degree of the size of the network request or the size of the sub-network request and the link quality of the plurality of available transmission links, wherein the better the quality of the transmission link is, the larger the storage resource occupied by the network request or the sub-network request corresponding to the transmission link is.
In this embodiment, when a plurality of network requests or sub-network requests are allocated to a plurality of transmission links, the allocation principle is that the better the link quality of the transmission link is, the larger the storage resource occupied by the network request or sub-network request allocated on the link is. For example, if the size of the sub HTTP request 1 is 10M, the size of the sub HTTP request 2 is 5M, the size of the sub HTTP request 3 is 8M, and the link quality is, in order, link 1, link 2, and link 3 from good to poor, then the sub HTTP request 1 may be assigned to link 1, the sub HTTP request 2 may be assigned to link 3, and the sub HTTP request 3 may be assigned to link 2.
In one non-limiting embodiment, link quality of the plurality of available transmission links is predicted using a neural network model. The neural network model may be pre-constructed and trained.
In a specific implementation, link parameters (such as packet loss rate, signal-to-noise ratio, time delay, etc.) for evaluating the link quality can be input into a neural network model, and the neural network model can output the link quality of the transmission link.
Further, when training the neural network model, training samples may be collected, where the training samples include various link parameters for evaluating link quality and values of link quality. And training the neural network model by using the training samples.
In a specific application scenario, please refer to fig. 3, an application 301 initiates an HTTP request 302, a pre-judging and assembling module 303 performs revenue pre-judging first, if the size of the network resource requested by the HTTP request 302 is predicted according to the quality of each current link and then the multi-link transmission is faster than that of a single link, the pre-judging and assembling module 303 fragments the HTTP request 302 and outputs the relevant information of the task to an allocating module 304. The distribution module 304 determines which link the task is sent from according to the task information and the link quality estimated by the link quality estimation module 305. The distribution module 304 distributes the different requests to different links according to a link distribution algorithm, thereby deriving a plurality of child Http requests. The plurality of child Http requests generate a plurality of response messages, and the anticipation and assembly module 303 caches and sorts the response messages and returns the response messages to the application 301. The whole process is transparent to the application and the bottom layer, and can be realized without the cooperation support of a server because the process is completed based on the HTTP standard.
The embodiment of the invention firstly segments the HTTP request based on the HTTP protocol of the application layer and distributes different segments to different transmission links, thereby enabling the network service of the application program to be capable of realizing multilink concurrence, further enabling the bandwidth to be overlapped and improved, and being capable of being completed without depending on the cooperation of services.
In another specific application scenario, the application 301 initiates multiple HTTP requests 302 simultaneously, and the anticipation and assembly module 303 directly sends information related to the multiple HTTP requests 302 to the allocation module 304. The distribution module 304 distributes the plurality of HTTP requests 302 to different links according to a link distribution algorithm. Compared with the former application scenario, in the application scenario, the prejudging and assembling module 303 does not need to fragment the HTTP request, and the response data does not need to be cached and sequenced, and is directly returned to the application program 301.
For example, in an application scenario where a browser browses a web page, one web page includes numerous sub-resources, and requests for different resources are dynamically allocated according to a link allocation algorithm, so that the effects of multilink concurrence and service data multilink aggregation are achieved.
It should be noted that the HTTP request 302 may also be replaced by a request of any other implementable application layer protocol, and the embodiment of the present invention is not limited thereto.
