Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The technical solution of the present invention is further illustrated by some specific examples.
Fig. 1 and fig. 2 are schematic diagrams illustrating application scenarios of a multipath data transmission method according to an embodiment of the present invention. The multipath data transmission method of the embodiment of the invention can be applied to unidirectional or bidirectional data transmission between the client and the server. The scenario shown in fig. 1 is an application scenario of downlink data transmission, that is, a server sends data to a client, and the scenario shown in fig. 2 is an application scenario of uplink data transmission, that is, an application scenario of a client uploading data to a server.
The following description will be given by taking downlink data transmission as an example. As shown in fig. 1, the client may be a smart phone, a tablet computer, a desktop computer, a notebook computer, or other devices, and an application program (APP) that initiates access to the server and obtains data is installed on the devices. The server may be a server that provides text, pictures, online video playing or downloading, provides live broadcast services, and the like, for example, a website server, an online video playing platform, an e-commerce platform, a CDN (Content Delivery Network) server that provides live broadcast services, and the like.
The transmission of the downlink data may be initiated by an Application (APP) of the client sending a data acquisition request to the server, thereby triggering the establishment of multiple data transmission paths. The path manager is arranged on the client and the server and used for interaction in the aspects of establishment, deletion, maintenance management and path flow use strategies of multiple data transmission paths, and the path manager is also used for generating the path flow use strategies on the client side. On the client side, information related to the network is obtained through a network environment management module and provided to a path management module to generate a path traffic usage policy. The network environment management module may be configured to, on one hand, sense a network environment condition where the device itself is located, for example, sense a WIFI signal, a cellular network (e.g., 3G, 4G, 5G), and on the other hand, initiate an inquiry of traffic tariff information to a server of a network operator, and specifically, initiate an inquiry to the server of the network operator through SIM (subscriber identity module) card information on the device. In addition, the network environment management module may further interact with an application to obtain an application requirement, where the application requirement refers to a requirement for data transmission when the application performs a certain function, for example, in the aspect of a live broadcast application, a bandwidth for initially entering a live broadcast stage is high, and after entering a live broadcast, a bandwidth requirement may be reduced, and for example, for a video playing application, a bandwidth requirement may be determined according to a resolution of a currently played video. After the network environment information, the traffic charge information and the application demand information are gathered to the path manager, a path traffic use strategy is generated.
In the embodiment of the present invention, Multipath (Multipath) refers to a path corresponding to a plurality of networks, and may be logically represented as a quadruple composed of a source IP, a destination IP, a source port, and a destination port. The path traffic usage policy may be, for example, for some users with a free-flow tariff, no extra cost is generated based on mobile data of a cellular network, and the path traffic usage policy may be a path of a WIFI network and a path of a cellular mobile network, and the maximum required bandwidth is targeted for use at will, and for some users with a high traffic tariff or having exceeded a package range of the free-flow traffic, the path traffic usage policy may be a path that preferentially uses the WIFI network, and only when the bandwidth of the WIFI network is lower than a certain threshold, the path of the cellular mobile network is reused.
On the server side, a packet scheduler is used to distribute packets to a certain path/paths according to certain preset algorithms and rules. The data packet to be sent is provided by a service program corresponding to the APP on the client, and an APP data sending end shown in the drawing may be a part of the service program, for example, the APP on the client is a short video application, and then a background service program providing short video data corresponds to the APP on the server, and after being scheduled by the data packet scheduler, the data packet is sent to the client in a multipath manner. The data packet scheduler is mainly used for scheduling data transmission according to the path state of each path and a path flow use strategy provided by the path manager, and after determining which path the data packet needs to be sent through, the data packet scheduler schedules the data packet to a corresponding congestion control module for sending the data packet, wherein the congestion control module 1 corresponds to a data transmission path corresponding to a WIFI network, and the congestion control module 2 corresponds to a data transmission path corresponding to a cellular network. The path state of the data transmission path may be detected by a packet loss detection and retransmission module, and the path state of each data transmission path may be determined by receiving a QoE (quality of experience) state reported by a response module from the client side and a response time of a response message. On the client side, the data packet receiver notifies the response module to return a response message to the server after receiving the data packet, and the QoE state information comes from the APP of the client.
In the application scenario shown in fig. 1, both an APP data sending end on a server and an APP data receiving end on a client belong to an upper layer application or a service program, and data receiving and sending are performed between the APP data sending end on the server and the APP data receiving end on the client through a module of a data transmission layer, that is, the upper layer application does not need to sense a specific data transmission path. In addition, the user may set a specific manner of traffic usage through the APP of the client, where the setting may include a function of turning on or turning off multi-path data transmission, or may include a setting of a traffic usage manner for a path corresponding to each network, for example, even if the traffic tariff of the user on the cellular network is high, the user may still pursue maximization of bandwidth through an active setting manner, and in addition, the user may set a different traffic usage manner for different APPs, for example, for short video applications, the user may set a traffic adaptation that does not limit each path, and for visiting a shopping website, a path traffic usage policy needs to be formed according to the situation of the traffic tariff, so as to avoid traffic waste. The traffic usage setting of the user is also one of the elements for generating the traffic usage policy.
The transmission scenario of downlink data is described above, and an application scenario of uplink data transmission will be described below with reference to fig. 2. Upstream data transmission scenarios may include situations such as an on-air client performing an upstream transmission of a live video stream, a user uploading a file to a cloud disk, and so on. The basic process of data transmission is identical to the transmission of downlink data as a whole, except that the roles of the client and the server are interchanged.
The transmission of the uplink data is also initiated by an Application (APP) of the client sending a data upload request to the server, thereby triggering the establishment of multiple data transmission paths. The path manager is arranged on the client and the server and used for interaction in the aspects of establishment, deletion, maintenance management and path flow use strategies of multiple data transmission paths, and similarly, on the client side, the path manager is also used for generating the path flow use strategies. In the transmission process of uplink data, the client is a data sending end, so that the scheduling processing of the data packet is performed on the client side, and the path manager on the client side does not need to report a path flow use strategy to the server side, but provides a data packet scheduler on the client side. The network environment management module lock performs the same function as that in fig. 1, and is used to obtain and summarize network environment information, traffic tariff information, and application requirement information to the path manager.
It should be noted that, in many cases, the uplink data transmission and the downlink data transmission may exist simultaneously, for example, when a user uses a short video application, the user may shoot and distribute a short video while watching the short video distributed by others, so that the uplink data transmission path and the downlink data transmission path need to be used simultaneously. In this case, based on the above multipath data transmission method, corresponding scheduling strategies may be executed in the process of output transmission of uplink and downlink, respectively. In addition, for the same application and the corresponding server, on the same physical network, the uplink data transmission path and the downlink data transmission path may be the same path or different paths, depending on the protocol configuration adopted by the output transport layer. In addition, in the above example, WIFI and cellular networks are taken as examples of two networks for explanation, in practical applications, there may also be multi-path transmission based on other network forms, for example, bandwidths of networks provided by different network operators are also different, some mobile phone users may have a mode of multiple SIMs, and may correspond to different network operators, and multiple data transmission paths may be established based on WIF and links of multiple different network operators. In addition, the plurality of data transmission paths are, for example, satellite signal access or cable television network access.
In addition, besides the user tariff policy, the network operators themselves may have different network service policies, for example, the bandwidth provided by the network operators is different at different time periods, or the bandwidth provided by the network operators is different for different applications, for example, some network operators may limit the uplink bandwidth, and so on. For these situations, in the method of the embodiment of the present invention, service policies of a network operator may be obtained, and a network state is determined or predicted based on the service policies, so as to perform a network transmission mode that is planned in advance and establishes multiple paths, so as to reduce the occurrence of delay. In addition, the service provided by different applications can be divided into service priorities, so that the multipath data transmission service can be preferentially used according to the priority ranking. In addition, when the multipath transmission service is provided for the user, the flow and the cost can be displayed for the user in real time, and information such as the network speed improved by the multipath transmission can be displayed, so that the user feeling of the multipath transmission service is enhanced. According to the multi-path data transmission method, the multiple data transmission paths corresponding to the multiple networks are established between the client and the server, and data transmission scheduling is carried out based on the path flow using strategy of the user and the path states of the data transmission paths, so that better network transmission quality is achieved while the control requirement of the user on the flow is considered, and the user experience quality is improved.
Fig. 3 is a flowchart illustrating a multipath data transmission method according to an embodiment of the present invention, which can be applied to a server side to provide downlink multipath data transmission to a client. The server can be a server for providing characters and pictures for the client, playing or downloading online videos and providing live broadcast services, and the server and the client can be connected through various types of networks. Specifically, the method may include:
s101: and responding to the data acquisition request of the client, and establishing a plurality of data transmission paths corresponding to different networks between the server and the client. The data obtaining request may be initiated by an APP on the client, for example, a user sends a short video playing request to the server through the APP, and if the network environment where the current client is located can provide multiple network options, a data transmission path between the client and the server may be established on the multiple network links for transmitting the short video data. The different networks referred to herein may be different physical network modes, such as WIFI or cellular networks or satellite communications, etc., or may be networks provided by different operators. In the embodiment of the invention, the establishment of the data transmission path can be established based on a QUIC (Quick UDP Internet Connection, fast UDP Internet Connection) protocol, the protocol is based on a UDP transmission layer, meanwhile, the reliability and the safety of protocols such as TCP, TLS, HTTP/2 and the like are achieved, and the Connection and transmission delay can be effectively reduced.
S102: the path states of a plurality of data transmission paths are acquired. The path state can be determined on the server side by detecting the packet loss rate and/or the data transmission speed of a plurality of data transmission paths. The packet loss rate and the data transmission speed can be determined by a response message returned to the server after the client receives the data packet and the QoE status information.
S103: and scheduling data transmission to the client on a plurality of data transmission paths according to the path flow use strategy of the user and the path state of each data transmission path. The scheduling process refers to allocating the data packets to one or more paths according to a preset algorithm and rule. The specific scheduling method may include: determining the weight of each data transmission path according to the path flow use strategy and the path state of the user, then distributing the data packet to be transmitted to each data transmission path according to the weight of each data transmission path, and transmitting the data packet to the client. The weight of each data transmission path can be dynamically changed according to the path traffic use strategy and the change of the path state of each data transmission path, so as to realize the optimized use of a plurality of paths. The path traffic usage policy may be generated by the client and reported to the server. Specifically, the server may obtain the path traffic usage policy through an interaction message for establishing the path in the process of establishing the path, and may use the policy from the client at a preset time interval after the path is established, so as to adjust the packet scheduling policy according to the latest path traffic usage policy.
The above path traffic usage policy may be determined according to traffic tariff information of the user and/or network environment information and/or traffic usage settings of the user and/or application requirements, and specifically, the client may detect a network environment condition in which the client device is located, for example, conditions such as a WIFI signal, a cellular network (e.g., 3G, 4G, 5G), and determine whether these networks are available to determine on which networks data transmission paths can be established. In addition, the client may also initiate a query of the traffic tariff information to a server of the network operator, specifically, the client may initiate the query to the server of the network operator through SIM (subscriber identity module) card information on the device, so as to obtain the traffic tariff information. In addition, the requirements in the aspect of data transmission corresponding to different applications are also different, and the client can obtain the requirements of the application initiating the data acquisition request on the current data transmission, for example, the requirements for picture browsing and the requirements for video playing are different, the requirements for picture browsing need to be transmitted as soon as possible to complete a complete picture, and the video playing is allowed to have a certain buffering time. After the client collects the network environment information, the traffic charge information and the application demand information, a path traffic use strategy is generated and reported to the server. It should be noted that, the generation of the path traffic usage policy may also be completed by the server side, that is, the client reports the network environment information, the traffic tariff information, and the application demand information to the server, and then the server dynamically generates the path traffic usage policy. However, the path traffic usage policy is generated at the client side and then reported to the server, so that the amount of reported information can be reduced, and the privacy of the user in terms of traffic charges can be better protected. In addition, the path traffic usage policy may also consider traffic usage settings of the user, and the operating system or each application of the client may provide an interactive interface for setting traffic usage for the user, so that the user can flexibly set a traffic usage mode according to the user's own requirements, specifically, the function of turning on or off multipath data transmission may be included, and the setting of the traffic usage mode for a path corresponding to each network may also be included.
According to the multi-path data transmission method, the multiple data transmission paths corresponding to the multiple networks are established between the client and the server, and data transmission scheduling is carried out based on the path flow using strategy of the user and the path states of the data transmission paths, so that better network transmission quality is achieved while the control requirement of the user on the flow is considered, and the user experience quality is improved.
As shown in fig. 4, which is a second flowchart of the multipath data transmission method according to the embodiment of the present invention, the method can be applied to a client side for performing uplink multipath data transmission to a server. Specifically, the method may include:
s201: and initiating a data uploading request to the server, and establishing a plurality of data transmission paths between the server and the client corresponding to different networks. Similar to the case of downstream data transmission, the data upload request described above may be initiated by an APP on the client, for example, by a host initiating an upstream transmission of a live video stream using a live application, by a user uploading a file to a server via a cloud disk application, and so on. The above-described establishment of the data transmission path may be established based on the QUIC protocol. The different networks may be different physical network modes, such as WIFI or cellular networks or satellite communications, etc., or may be networks provided by different operators.
S202: the path states of a plurality of data transmission paths are acquired. The difference from downlink data transmission is that the detection of the path state is performed by the client side, and the path state can be determined by detecting the packet loss rate and/or the data transmission speed of a plurality of data transmission paths. The packet loss rate and the data transmission speed can be determined by a response message returned to the client after the server receives the data packet and the QoE status information.
S203: and scheduling data transmission to the server on the plurality of data transmission paths according to the path flow using strategy of the user and the path state of each data transmission path. The multipath-based packet scheduling and downlink data transmission are similar, except that the scheduling is performed at the client side, and the specific scheduling method may include: determining the weight of each data transmission path according to the path flow use strategy and the path state of the user, then distributing the data packet to be transmitted to each data transmission path according to the weight of each data transmission path, and transmitting the data packet to the server. The weight of each data transmission path can be dynamically changed according to the path traffic use strategy and the change of the path state of each data transmission path, so as to realize the optimized use of a plurality of paths. In addition, in the process of scheduling, the path traffic usage policy may also be acquired at preset time intervals, so as to update the scheduling policy.
Since the scheduling processing for the data packet occurs at the client side, the path traffic usage policy can be locally generated at the client and directly used for the scheduling processing without reporting to the server. Similar to the downlink data transmission situation, the path traffic usage policy may be determined according to traffic tariff information of the user and/or network environment information and/or traffic usage settings and/or application requirements of the user. The acquisition of traffic tariff information, network environment information and/or user traffic usage settings and application requirements is in accordance with the above described approach. The path traffic usage policy may be generated at preset time intervals according to the information and used for scheduling.
According to the multi-path data transmission method, the multiple data transmission paths corresponding to the multiple networks are established between the client and the server, and data transmission scheduling is carried out based on the path flow using strategy of the user and the path states of the data transmission paths, so that better network transmission quality is achieved while the control requirement of the user on the flow is considered, and the user experience quality is improved.
Fig. 5 is a schematic structural diagram of a multipath data transmission apparatus according to an embodiment of the present invention, which can be applied to a server side to provide downlink multipath data transmission to a client. The server can be a server for providing characters and pictures for the client, playing or downloading online videos and providing live broadcast services, and the server and the client can be connected through various types of networks. Specifically, the apparatus may include:
and a path establishing module 11, configured to establish, in response to a data acquisition request of the client, multiple data transmission paths between the server and the client, where the multiple data transmission paths correspond to different networks. The data acquisition request may be initiated by an APP on the client, and if the network environment in which the current client is located can provide multiple network options, a data transmission path between the client and the server may be established over the multiple network links. The different networks referred to herein may be different physical network modes, such as WIFI or cellular networks or satellite communications, etc., or may be networks provided by different operators.
A path status acquiring module 12, configured to acquire path statuses of multiple data transmission paths. The path state can be determined on the server side by detecting the packet loss rate and/or the data transmission speed of a plurality of data transmission paths. The packet loss rate and the data transmission speed can be determined by a response message returned to the server after the client receives the data packet and the QoE status information.
And the scheduling module 13 is configured to perform scheduling processing on the multiple data transmission paths to transmit data to the client according to the path traffic utilization policy of the user and the path states of the data transmission paths. The scheduling process refers to allocating the data packets to one or more paths according to a preset algorithm and rule. The specific scheduling method may include: determining the weight of each data transmission path according to the path flow use strategy and the path state of the user, then distributing the data packet to be transmitted to each data transmission path according to the weight of each data transmission path, and transmitting the data packet to the client. The weight of each data transmission path can be dynamically changed according to the path traffic use strategy and the change of the path state of each data transmission path, so as to realize the optimized use of a plurality of paths. The path traffic usage policy may be generated by the client and reported to the server. Specifically, the server may obtain the path traffic usage policy through an interaction message for establishing the path in the process of establishing the path, and may use the policy from the client at a preset time interval after the path is established, so as to adjust the packet scheduling policy according to the latest path traffic usage policy.
The above path traffic usage policy may be determined according to traffic tariff information of the user and/or network environment information and/or traffic usage settings of the user and/or application requirements, and specifically, the client may detect a network environment condition in which the client device is located, for example, conditions such as a WIFI signal, a cellular network (e.g., 3G, 4G, 5G), and determine whether these networks are available to determine on which networks data transmission paths can be established. In addition, the client may also initiate a query of the traffic tariff information to a server of the network operator, specifically, the client may initiate the query to the server of the network operator through SIM (subscriber identity module) card information on the device, so as to obtain the traffic tariff information. In addition, the requirements in the aspect of data transmission corresponding to different applications are also different, and the client can obtain the requirements of the application initiating the data acquisition request on the current data transmission. After the client collects the network environment information, the traffic charge information and the application demand information, a path traffic use strategy is generated and reported to the server. It should be noted that, the generation of the path traffic usage policy may also be completed by the server side, that is, the client reports the network environment information, the traffic tariff information, and the application demand information to the server, and then the server dynamically generates the path traffic usage policy. However, the path traffic usage policy is generated at the client side and then reported to the server, so that the amount of reported information can be reduced, and the privacy of the user in terms of traffic charges can be better protected. In addition, the path traffic usage policy may also consider traffic usage settings of the user, and the operating system or each application of the client may provide an interactive interface for setting traffic usage for the user, so that the user can flexibly set a traffic usage mode according to the user's own requirements, specifically, the function of turning on or off multipath data transmission may be included, and the setting of the traffic usage mode for a path corresponding to each network may also be included.
According to the multi-path data transmission device, the multiple data transmission paths corresponding to the multiple networks are established between the client and the server, and data transmission scheduling is carried out based on the path flow using strategy of the user and the path states of the data transmission paths, so that better network transmission quality is achieved while the control requirement of the user on the flow is considered, and the user experience quality is improved.
Fig. 6 is a second schematic structural diagram of a multipath data transmission apparatus according to an embodiment of the present invention, which can be applied to a client side for performing uplink multipath data transmission to a server. Specifically, the apparatus may include:
the path establishing module 21 is configured to initiate a data upload request to the server, and establish multiple data transmission paths between the server and the client, where the multiple data transmission paths correspond to different networks. Similar to the case of downstream data transfer, the data upload request described above may be initiated by the APP on the client. The above-described establishment of the data transmission path may be established based on the QUIC protocol. The different networks may be different physical network modes, such as WIFI or cellular networks or satellite communications, etc., or may be networks provided by different operators.
A path status acquiring module 22, configured to acquire path statuses of multiple data transmission paths. The difference from downlink data transmission is that the detection of the path state is performed by the client side, and the path state can be determined by detecting the packet loss rate and/or the data transmission speed of a plurality of data transmission paths. The packet loss rate and the data transmission speed can be determined by a response message returned to the client after the server receives the data packet and the QoE status information.
And the scheduling module 23 is configured to perform scheduling processing of transmitting data to the server on the plurality of data transmission paths according to the path traffic usage policy with the user and the path states of the data transmission paths. The multipath-based packet scheduling and downlink data transmission are similar, except that the scheduling is performed at the client side, and the specific scheduling method may include: determining the weight of each data transmission path according to the path flow use strategy and the path state of the user, then distributing the data packet to be transmitted to each data transmission path according to the weight of each data transmission path, and transmitting the data packet to the server. The weight of each data transmission path can be dynamically changed according to the path traffic use strategy and the change of the path state of each data transmission path, so as to realize the optimized use of a plurality of paths. In addition, in the process of scheduling, the path traffic usage policy may also be acquired at preset time intervals, so as to update the scheduling policy.
Since the scheduling processing for the data packet occurs at the client side, the path traffic usage policy can be locally generated at the client and directly used for the scheduling processing without reporting to the server. Similar to the downlink data transmission situation, the path traffic usage policy may be determined according to traffic tariff information of the user and/or network environment information and/or traffic usage settings and/or application requirements of the user. The acquisition of traffic tariff information, network environment information and/or user traffic usage settings and application requirements is in accordance with the above described approach. The path traffic usage policy may be generated at preset time intervals according to the information and used for scheduling.
According to the multi-path data transmission device, the multiple data transmission paths corresponding to the multiple networks are established between the client and the server, and data transmission scheduling is carried out based on the path flow using strategy of the user and the path states of the data transmission paths, so that better network transmission quality is achieved while the control requirement of the user on the flow is considered, and the user experience quality is improved.
