The following explains an application scenario and an inventive concept of the present application.

Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. The data transmission system provided by the application can be applied to the application scenario shown in fig. 1. As shown in fig. 1, the application scenario includes: a first end-side device 101, an on-cloud system 102, and a second end-side device 103; wherein, the on-cloud system 102 may include a private cloud, an edge cloud, and a multi-cloud; for example, in the live broadcast field, the anchor may acquire and upload audio and video data through the first end-side device 101, the cloud system 102 may send the audio and video data to the second end-side device 103 of the audience, in the audio and video data transmission process, the cloud system 102 may select to transmit the audio and video data to the second end-side device 103 through a node deployed on a special cloud, or may select to transmit the audio and video data to a node deployed on a certain edge cloud first, further, transmit the audio and video data to a node deployed on a certain cloudy through a node on the edge cloud, and a node on the cloudy may transmit the audio and video data to the second end-side device 103.

Specifically, the on-cloud system 102 selects based on the actual condition of the current network operation quality, selects an optimal transmission path to transmit the audio/video data to the second end-side device 103, and when a network fault or a decrease in the quality of the original path is found, automatically plans a new data transmission path, selects a suitable node on the cloud to transmit the data, and reduces packet loss or delay influence caused by network jitter.

It should be noted that the application scenario of the data transmission system provided in the embodiment of the present application may also be applicable to a multi-cloud deployment scenario in which data transmission is performed on cloud services, such as data transmission performed by a host device and a server in a live broadcast field, data transmission performed by a user device and a service server in a cloud game field, data transmission performed by a user device and a server in a meta-universe field, and data transmission performed by a user device and another user server in an online conference, and the like, which are not listed herein.

It can be understood that the application scenario of the present application may further include other clouds, such as an ari cloud, a public cloud, or a hybrid cloud, where a node may be a virtual machine or a container, and is deployed on different regions and different types of clouds to implement data forwarding.

In a possible implementation manner, an Avatrix management platform may be used to perform unified management on multiple cloud platform networks to implement transmission of network data, but the Avatrix management platform may only ensure connectivity of the cloud platform, does not provide performance optimization of network transmission, and if network jitter occurs, a message may not be received, which may affect a data transmission effect.

In another possible implementation manner, traffic access may be completed through a cloud Virtual client device (vCPE), an application identification module embedded in the system identifies an application traffic that a user needs to accelerate, and a path optimization is provided for access of an application by using POP nodes distributed in different areas.

However, the transmission quality guarantee of the traffic is completed by widely deploying POP points, the construction and maintenance cost of the system is high, the elastic expansion capability is insufficient, only a specific type of transmission service (such as low delay) can be provided for the service, customized network traffic management cannot be provided for the service traffic, the flexibility is poor, and the data transmission quality is affected.

In another possible implementation manner, if the scenario of audio/video transmission is targeted, audio/video transmission may also be performed based on a cloudy Microsoft Developer Network (MSDN) with massive ordered data. The MSDN checks the real-time network operation quality by detecting the quality of each segment of network line in real time. When a network fault is found or the quality of the original path is reduced, a new data transmission path can be automatically planned, and the packet loss or delay influence caused by network jitter is reduced.

However, the above method only provides a specific type of transmission optimization service for the service, the application scenario is limited, and the MSDN overall solution only solves the traffic classification and the path management of different classification granularities, and the end-to-end quality of the MSDN overall solution greatly depends on the quality condition of the selected path itself, which affects the transmission quality.

In view of this, an embodiment of the present application provides a data transmission system, where an end-side device in the data transmission system may send a data packet to be transmitted and an identifier corresponding to the service and the function to a cloud system according to a service and a function to be processed, and after obtaining the data packet sent by the end-side device, the cloud system may determine a corresponding transmission policy according to the service and the function, so as to meet requirements of different services and functions.

Wherein the service may include at least one of: live, cloud games, online conferences, meta universes, etc.

In the embodiment of the application, different transmission strategies can be set for different services, and illustratively, the real-time requirement of the cloud game service is higher than that of other services, so that the cloud system can use a transmission path and a retransmission strategy with better real-time property when transmitting the data packet of the cloud game.

Further, the embodiment of the application supports setting different transmission strategies for different functions of the same service.

In cloud gaming services, the functions may include: control instructions, game screens, in-team messages, system notifications, comments, and the like. The first end-side device may be a terminal device used by a player, such as a mobile phone, and the second end-side device may be a service server of a cloud game. The first end side device can transmit a control instruction triggered by a player in a game process to the service server through the on-cloud system, and the service server can return a corresponding game picture through the on-cloud system according to the control instruction. In addition, other functions such as in-team messages are supported, and the business server serves as a first end-side device to send the in-team messages to the mobile phones of other players.

When a player operates on a game interface of the cloud game, the first end-side device can determine a corresponding function according to the operation of the player and identify the function in a sent data packet, and when a cloud system transmits the data packet, different service functions have different quality requirements and can correspond to different available transmission paths and retransmission strategies.

Exemplarily, if the function corresponding to the data packet is a control instruction, high real-time performance is required, and a transmission path and a retransmission strategy with high real-time performance can be selected; if the function corresponding to the data packet is the in-queue message, the real-time requirement is relatively low, and a transmission path and a retransmission strategy with corresponding quality can be selected for the in-queue message.

Illustratively, the real-time requirement and bandwidth requirement of the live broadcast service are higher than those of other services, so that the system on the cloud can use a transmission path and a scheduling strategy with better real-time requirement and bandwidth when transmitting live broadcast data packets.

In a live service, the functions may include: comments, praise, private letter, coupon, 3D special effects, etc. The first end-side device may be a terminal device used by the anchor, such as a mobile phone, and the second end-side device may be a terminal device of the viewer. The first end side device can transmit the coupon robbing link issued by the anchor in the live broadcast process to the terminal device of the audience through the cloud system, and the terminal device of the audience can return the corresponding user information of the coupon robbed through the cloud system according to the link. In addition, other functions such as comments and private letters are supported, and the terminal equipment of the audience serves as first end side equipment to send contents such as comments and private letters to the mobile phone used by the anchor.

When the anchor operates on a live display interface, the first end-side device can determine a corresponding function according to the operation of the anchor and identify the function in a sent data packet, and when the cloud system transmits the data packet, the corresponding transmission strategy is selected according to the difference of the functions.

For example, if the function corresponding to the data packet is a coupon, high real-time performance and network bandwidth are required, a transmission path and a retransmission policy with high real-time performance may be adopted, and if the function corresponding to the data packet is live content, the requirement on real-time performance is low, but the requirement on network bandwidth is high, an optimal path may be calculated to transmit data according to the requirement on the service function.

In an audio-video conference, the functions may include: voice transmission, file upload, screen sharing, text messaging, video content transmission, and the like. The first end-side device may be a terminal device used by the moderator, such as a tablet computer, and the second end-side device may be a terminal device of another participant. The first end side equipment can transmit the screen shared by the host in the conference process to the terminal equipment of other participants through the on-cloud system, the terminal equipment of other participants can watch the shared screen, in addition, the terminal equipment of other participants can send voice messages, text messages and the like, and further, the contents such as the voice messages, the text messages and the like sent by the terminal equipment of other participants as the first end side equipment are returned through the on-cloud system.

When the host operates on a display interface of the live conference, the first end-side device can determine a corresponding function according to the operation of the host, identify the function in the sent data packet, and select a corresponding transmission strategy according to different functions when the cloud system transmits the data packet.

Exemplarily, if the function corresponding to the data packet is video content transmission, a higher network bandwidth is required, an available transmission path and a retransmission policy that satisfy the corresponding requirement may be adopted, and if the function corresponding to the data packet is text message content, the real-time requirement and the bandwidth requirement are lower, an optimal path may be calculated to transmit data according to the requirement of the service function.

In the field of metastables, the functions may include: gaming activities, educational activities, shopping activities, and the like. Wherein each behavior comprises at least one specific function, for example, the shopping behavior comprises a behavior instruction of purchasing clothes, a behavior instruction of purchasing stocks, a behavior instruction of purchasing land, and the like; the first end-side device may be a terminal device used by a user, such as Virtual Reality (VR) glasses, and the second end-side device may be a server of the metastic space. The first end side equipment can transmit a behavior instruction of a user for purchasing a commodity to a server of the meta universe through the on-cloud system, the server of the meta universe can return a corresponding shopping consumption list through the on-cloud system according to the behavior instruction for purchasing the commodity, in addition, other functions such as commodity information displaying and the like are supported, and the server of the meta universe is used as the first end side equipment to send the commodity information to the terminal equipment of the user for the user to check.

For example, if the function corresponding to the data packet is to purchase stocks, high real-time performance is required, and a transmission path and a retransmission strategy with high real-time performance may be adopted, and if the function corresponding to the data packet is to purchase clothing, the requirement on real-time performance is low, and a transmission path and a retransmission strategy with corresponding quality are selected for the function.

Through the embodiment, the data transmission system can select a proper strategy for data transmission based on the service and the function customization of the data packet, so that the flexibility of data transmission is greatly improved.

Optionally, the gateway node information may include current load information of each gateway node in the cloud system; further, the first end-side device determines a target gateway node according to current load information of each gateway node, for example, the gateway node information includes that the remaining bearable traffic of the gateway node 1 at the current time is 10G, the remaining bearable traffic of the gateway node 2 at the current time is 1G, and the remaining bearable traffic of the gateway node 3 at the current time is 100G; the first end-side device may select the gateway node 3 that has the largest remaining bearable flow at the current time, further transmit the data packet to be transmitted to the gateway node 3, and the gateway node 3 may transmit the data packet to be transmitted to the second end-side device through other nodes. Therefore, the gateway node which can bear the largest flow in the current load information is selected for data transmission, the utilization rate of the gateway node is improved, and the data transmission rate can be improved.

With the above embodiment, the first end-side device may determine the target gateway node according to any one of the position, the type, the current load information, the service type and the function corresponding to the data packet to be transmitted, so as to transmit the data packet.

Optionally, the gateway node information includes types and corresponding load information of each gateway node in the cloud system; further, the first end-side device determines a target gateway node according to the type of each gateway node and corresponding current load information, for example, the gateway node information includes that the gateway node 1 is a central cloud, the current load information is a forwardable traffic 1G, the node 2 is a proprietary cloud, the current load information is a forwardable traffic 100G, the gateway node 3 is an edge cloud, and the current load information is a forwardable traffic 10G; the first end-side device may select the gateway node 2 if the forwarding traffic is the largest in the private cloud, and further transmit the data packet to be transmitted to the gateway node 2, and the gateway node 2 may transmit the data packet to be transmitted to the second end-side device.

It can be understood that the first end-side device may further determine a target gateway node according to at least two of the location, the type, the current load information, the service type and the function corresponding to the data packet to be transmitted, so as to transmit the data packet.

Illustratively, if the first end-side device comprehensively determines a target gateway node according to the position, the type, the current load information, the service type corresponding to the data packet to be transmitted, and the function of each gateway node, for example, the determined target gateway node is close to the first end-side device, the type meets the requirement, and the current load information on the cloud server of the type meets the service type corresponding to the data packet to be transmitted and the transmission requirement of the function, so that the determined target gateway node is optimal among all selectable gateway nodes, and the transmission effect is greatly improved while the transmission requirement is met.

It should be noted that the first end-side device may obtain gateway node information from a controller in the cloud system, and each gateway node in the cloud system establishes communication with the controller, so that the controller may obtain gateway node information corresponding to each gateway node point and perform global computation on the gateway node information. The algorithm of the target gateway node determined by calculation may be a weighted algorithm, and the minimum value is taken or input into the network model.

Optionally, after accessing the gateway node, the end-to-end path of the network may be actively controlled by deploying the transit node in the network, that is, after obtaining the data packet, the data packet may be transmitted to the gateway node corresponding to the second end-side device via at least one transit node, or after obtaining the data packet, the data packet may be directly transmitted to the gateway node corresponding to the second end-side device.

The enabled transfer node can be determined according to the load condition of the area, and further the gateway node forwards the data packet to the determined transfer node for transmission, or the transfer nodes are all opened, at least part of nodes needing to be closed can be determined according to the load condition of the area, and then the gateway node forwards the data packet to the opened transfer node for transmission, so that the resource waste can be reduced, and under the condition of meeting the load condition of the area, a proper node is selected for data transmission.

By the scheme, the target gateway nodes meeting different scene requirements can be selected, the selection flexibility is improved, the data transmission requirements in each data transmission process are met, and part of the nodes are selected for data transmission, so that the resource waste is reduced, and the transmission effect is improved.

In one or more embodiments of the present application, optionally, the on-cloud system further includes a controller;

the controller is configured to: determining node quality information corresponding to each node, wherein the node quality information comprises at least one of the following items detected in real time: throughput information, delay information, packet loss information; determining a list corresponding to each node according to the node quality information and the optional demand information; the list corresponding to each node comprises a next hop node which can be selected by the node under each requirement information and a selection probability corresponding to each next hop node;

each node in the on-cloud system is configured to: acquiring a list sent by the controller; and searching selectable next hop nodes under the corresponding requirement information from the list according to the data packet to be transmitted, and determining the next hop nodes for transmitting the data packet according to the selection probability of each next hop node.

In this embodiment, the throughput information may refer to throughput; the delay information may refer to a delay time or a delay rate; the packet loss information may refer to a packet loss amount or a packet loss rate.

Optionally, the list refers to a transmission path list that is available for the controller to calculate and generate traffic of different pieces of demand information after synthesizing the global path quality information, for example, the demand information may be a QoS demand, and the QoS demand includes demands on bandwidth, delay, reliability, and the like; the transmission path list includes each next hop node and a selection probability corresponding to each next hop node, where the controller may generate a node list in which the next hop of the node is selectable for each node.

For example, table 1 is an example of a list generated by the controller for the node 1 according to the embodiment of the present application, and as shown in table 1, the list generated by the controller for the node 1 may include a destination, requirement information, optional nodes, a selection probability of each optional node, and the like.

Table 1 example of a list generated by a controller for node 1

As can be seen from the table, under the same destination and the same requirement information, there may be a plurality of selectable nodes, when the destination corresponding to the data transmission of node 1 is port 1, and the code of the requirement information is 1, there are node 3, node 2 and node 5 as next-hop selectable nodes, and their corresponding selection probabilities are 0.7, 0.2 and 0.1, respectively.

Specifically, the controller may set a corresponding list for each node according to different destinations or different QoS requirements. For example, each node in the list needs to meet the QoS requirement, that is, any one of throughput information, delay information, and packet loss information corresponding to the node selectable by the next hop cannot exceed a threshold corresponding to the QoS requirement, or each node in the list needs to meet the requirement of the destination.

Further, each node in the cloud system may obtain the list sent by the controller, determine a next hop node to be selected according to a QoS requirement and a destination corresponding to a data packet to be transmitted, and select one of the nodes as the next hop node for transmitting the data packet based on a selection probability of each node.

Fig. 6 is a schematic structural diagram of another data transmission system provided in an embodiment of the present application, and as shown in fig. 6, the system may include a controller 104, where the controller 104 may obtain demand information corresponding to a data packet sent by the first end-side device 101, and may also obtain quality information of each node in the cloud system, further, determine a list corresponding to each node according to the quality information of each node and the demand information, and feed the list back to each node in the cloud system, where each node in the cloud system searches for a next hop node selectable under the corresponding demand information from the list according to the data packet sent by the first end-side device 101, and determines a next hop node used for transmitting the data packet according to a selection probability of each next hop node.

Therefore, the controller can control the global calculation of a list of each node under different QoS requirements and/or destination requirements, the list comprises selection probabilities corresponding to the next hop of selectable nodes, the next hop of nodes for transmitting the data packet is determined based on the selection probability of each selectable node, the accuracy of the selected nodes is improved, the data packet is transmitted to the next hop of nodes, and the transmission effect is improved.

In one or more embodiments of the present application, optionally, when determining the list corresponding to each node, the controller is specifically configured to:

for each optional requirement information, searching a next hop node meeting the requirement information;

and adjusting the weight of each item of information in the node quality information according to the requirement information, and determining the selection probability of each found next hop node according to the weight of each item of information.

In this embodiment, each item of information in the quality information includes throughput information, delay information, packet loss information, and the like corresponding to each node, and may be represented as determination of throughput, delay time, and packet loss rate corresponding to each node. Optionally, the selection probability of the node is in a direct proportional relationship with the throughput information corresponding to each node, and is in an inverse proportional relationship with the delay information or the packet loss information, that is, the greater the throughput, the greater the selection probability of the corresponding node, the smaller the delay time, and the smaller the selection probability of the corresponding node, and the weights corresponding to the throughput information, the delay information, and the packet loss information are determined according to the QoS requirements, and each node performs weighted summation on the throughput information, the delay information, the packet loss information, and the like to obtain the selection probability of the node.

Optionally, taking QoS requirements as an example, a list corresponding to a certain node is set based on different indexes corresponding to QoS requirements, where the QoS requirements are a shaped number, and include different indexes such as delay, reliability, bandwidth, and the like, and respectively correspond to delay information, packet loss information, and throughput information; each index can be classified into three grades, i.e., high, medium, and low, specifically, as a QoS requirement lookup table shown in table 2, an index corresponding to data transmission can be found by determining an identification number corresponding to a QoS requirement, where table 2 only shows 9 possible cases when an index corresponding to delay is a high grade, and when an index corresponding to delay is a medium or low grade, there are 9 possible cases respectively, which is not listed here.

Table 2 QoS requirements look-up table

Furthermore, the list corresponding to the QoS requirement is searched according to the identification number corresponding to the QoS requirement, and the speed of searching the list can be improved.

It is understood that the above embodiments are only examples, and the QoS requirement in practical applications should be determined according to specific situations.

It should be noted that, under the condition that the same node has the same destination and QoS requirements, the selection probabilities of the selectable nodes of the next hop may be different, and first, some nodes may not meet the QoS requirements, so that the corresponding selection probability is 0, and in addition, the selection probability in the weighted summation of each index may also be flexibly set according to the QoS requirements, for example, the requirement on real-time performance is high, the weight of delay time is great, and the weight of packet loss rate is great with priority on reliability.

Therefore, the weight of each quality index can be adjusted according to the QoS requirement, for example, the requirement on real-time performance is high, the weight of delay information is improved, the requirement on reliability is high, the weight of packet loss information is improved, the service processing effect is improved, and the requirements of different data transmission are met.

In one or more embodiments of the present application, optionally, the list is updated periodically; the period is determined by the service and the function corresponding to the data packet currently transmitted by the cloud system;

the list is also used for indicating an optimal node, and the optimal node is a next hop node determined only by packet loss information and delay information;

in any period, each node uniformly selects a next hop node for at least one data packet of the same quintuple, and if the data packet with abnormal transmission exists in the at least one data packet, the data packet with abnormal transmission is redirected to the optimal node for transmission.

In this embodiment, a quintuple refers to a set formed by five quantities, i.e., a source IP address, a source port, a destination IP address, a destination port, and a transport layer protocol, and a packet under a service/function may have one or more quintuples.

Optionally, the list and the weight corresponding to each index may be updated according to a period, the length of the period is determined by a service and a function corresponding to a data packet currently transmitted by the cloud system, and the period may be adjusted according to the requirement information or may be fixed; for example, a certain area or a certain type of nodes are currently in a cloud game peak period, most nodes transmit cloud game data packets, and at the moment, the requirement on demand information is high, so that the period can be shortened adaptively; or, different fixed periods are directly configured for different nodes, that is, each node has a corresponding fixed period.

For example, after a forward path is specified for traffic, if a packet is lost in a current path, retransmission can be completed only after a plurality of RTTs are performed on the packet-lost traffic, and an optimal node may be indicated in the list in the present application, that is, a next hop node determined according to packet-lost information and delay information may be used. In this way, the stability of data transmission can be improved.

It can be understood that the condition that a response returned by the next hop node to a certain data packet is not received within the preset time includes the condition that a data packet with abnormal transmission occurs, such as a data packet with retransmission/out-of-order occurrence, a data packet subjected to multiple discarding, and the like.

It should be noted that the controller may generate a corresponding list for guiding traffic transmission in the next period based on the situation in the previous period statistically.

In summary, when the transmission is performed based on the quintuple, if there is a retransmitted/out-of-order packet, the optimal node may be reselected for transmission, and the optimal node only considers packet loss information and delay information, and does not consider other conditions such as throughput information, etc., thereby speeding up the packet loss recovery process, reducing the impact on throughput, and improving the stability of data transmission.

In one or more embodiments of the present application, optionally, the system on the cloud is further configured to: determining a data packet encapsulation mode of the node according to the type of each node and/or the type of a next hop node corresponding to the node;

the nodes in the transmission path are configured to: analyzing the obtained data packet, and encapsulating the analyzed data packet according to a corresponding encapsulation mode; and sending the encapsulated data packet to a next hop node.

Optionally, the types corresponding to each node are distinguished, and the encapsulation mode of the node for the data packet is determined according to the type corresponding to each node, so that the data security is improved, the data processing is more flexible and efficient, and the types can be divided into gateway nodes and transit nodes. For example, for a gateway node, that is, a node in communication connection with a first end-side device or a second end-side device, the first end-side device encapsulates a data packet in a GRE encapsulation manner, and further, accesses the encapsulated data packet to the gateway node; and for the transit node, a TCP header-based four-layer encapsulation mode is adopted for encapsulation, so that a flow control strategy for UDP possibly encountered in the process of passing through a wide area network can be reduced, and the flexibility of network flow management is improved.

By the scheme, the encapsulation mode and the analysis mode of the node for the data packet are determined according to the type corresponding to different nodes and/or the type of the next hop node corresponding to the node, so that the safety of data transmission is improved, and the data processing is more flexible and efficient.

In one or more embodiments of the present application, optionally, the identifier is a differentiated service coding point corresponding to the demand information; the differentiated services coding point is used for indicating at least one of the following requirements: bandwidth requirements, latency requirements, reliability requirements;

the first end-side device is specifically configured to: and packaging the data packet to be transmitted according to the differentiated service coding points corresponding to the service and the function, and sending the packaged data packet to the cloud system so that the cloud system selects a transmission path for the data to be transmitted according to the differentiated service coding points.

In the embodiment of the present application, the bandwidth requirement may refer to a bandwidth required when transmitting a data packet; latency requirements may refer to requirements on the length of time for data transmission; the reliability requirement may refer to a stability requirement for data transmission, for example, a phenomenon that a packet loss phenomenon or a transmission abnormality does not occur.

Optionally, after the controller interacts with the first end-side device, the controller configures a DSCP for the specified traffic, and the first end-side device may encapsulate the data packet by using the DSCP to complete marking of the QoS requirement, that is, performing corresponding DSCP marking on a bandwidth requirement, a delay requirement, a reliability requirement, and the like required by data transmission. The gateway node and the transit node can provide differentiated QoS service for the DSCP marks after obtaining the DSCP marks.

Optionally, the controller in the cloud system is specifically configured to determine a list of each node according to a requirement indicated by the selectable differentiated service coding point; the nodes in the cloud system are specifically configured to select a next hop node for a data packet from a corresponding list according to a differentiated service coding point of the data packet to be transmitted.

For example, a controller in the cloud system may establish communication with the first end-side device, and further, the controller may store a DSCP corresponding to each QoS requirement and send the DSCP to the first end-side device, so that the first end-side device may determine the corresponding QoS requirement based on the type of the service request, determine the DSCP corresponding to the QoS requirement, encapsulate the data packet to be transmitted, and send the encapsulated data packet to the cloud system.

Therefore, according to the embodiment of the application, bandwidth requirements, delay requirements and reliability requirements can be indicated through the DSCP, the data packet is encapsulated according to the DSCP, the efficiency and accuracy of data packet encapsulation are improved, the data volume of the data packet is reduced, data transmission can be achieved through the cloud system according to the requirements indicated by the DSCP, and the efficiency and accuracy of selecting a transmission path are improved.

In one or more embodiments of the present application, optionally, the first end-side device implements service processing through multiple threads, where each thread is used to process at least one function corresponding to a same differentiated service coding point; the first end-side device is further configured to: and responding to the operation information of a user, selecting a thread corresponding to the function to which the operation information belongs, processing the operation information to obtain a data packet to be transmitted, and encapsulating the data packet according to the differentiated service coding point corresponding to the thread.

For example, the first end-side device may configure a thread for processing operation information of a user according to requirements of different services and functions, where the operation information of the user may be a comment private letter performed by the user through touching the first end-side device in live broadcasting, and further, the first end-side device selects a corresponding thread based on the comment private letter function corresponding to the operation information of the user, processes the operation information to obtain a data packet to be transmitted, and further, the thread encapsulates the data packet based on a DSCP corresponding to the comment private letter function, so that the first end-side device sends out the encapsulated data packet. Therefore, the corresponding threads can be determined to process based on the requirements of the service and the function, the processing can be performed in a targeted manner, the processing accuracy is improved, and the data packets can be encapsulated according to the differentiated service coding points corresponding to the threads, so that the differentiation is facilitated.

Optionally, different services or functions may correspond to the same or different DSCPs, and each DSCP may correspond to one thread.

Optionally, in the above embodiment, if the first end-side device selects a corresponding thread based on a comment private message function corresponding to operation information of a user, and processes the operation information to obtain a compressed data packet to be transmitted, further, the cloud system may determine that the level of the user is low based on the DSCP, and determine that the level corresponding to the demand information is also low, select a level based on the user and a level corresponding to the demand information, and screen an optional next hop node for data transmission.

Therefore, when the next hop node is selected, the cost information of each node and the grade corresponding to the user are considered, the corresponding node can be selected for different users to carry out data transmission, namely the user with the high grade can select the node with the high cost, the transmission quality corresponding to the node with the high cost is good, the experience of the user is improved, and the expenditure is saved.

Optionally, the node quality information further includes cost information of the node; the differentiated services coding point is further to indicate: the grade corresponding to the user using the service or function; and the on-cloud system is also used for screening the next hop node selectable under the demand information according to the cost information of the node and the grade corresponding to the demand information.

In the embodiment of the present application, when calculating the selection probability corresponding to the selectable next hop node, the selection probability may further include an index of cost information of the node, where the cost information may refer to costs of nodes deployed in different places and different manufacturers, and the cost may be a fixed value and may not change with an actual data transmission condition; the cost information may correspond to a user level in the QoS requirement, and a next hop node with higher cost may be used when the user level is higher, and if the user level is lower when the next hop node selectable under the QoS requirement is screened, but the cost information is higher, the next hop node may not be selected.

Therefore, the nodes meeting different scene requirements can be screened out based on the grade corresponding to the user and the cost information, automatic control and personalized processing of cost are conveniently achieved, and overall efficiency of data transmission and user experience are improved.

In one or more embodiments of the present application, optionally, the data transmission system further includes a control device for interacting with an enterprise user providing a service;

the control device is configured to: displaying an optional demand information list corresponding to the business provided by the enterprise user; acquiring configuration information input by the enterprise user, wherein the configuration information is used for indicating the business and/or requirement information corresponding to each function in the business; sending the configuration information to at least one other device or node in the data transmission system; and the at least one other device or node is used for determining the requirement information corresponding to the data package to be transmitted according to the configuration information of each enterprise user and the enterprise user to which the service corresponding to the data package to be transmitted belongs.

Optionally, the user may edit the correspondence between the QoS requirement and the quintuple, or the user may independently select the QoS requirement, because the enterprise user may provide one or more services, and each service may correspond to one or more functions, so that the delay of the cloud game 1 is smaller than that of the cloud game 2 by configuring the requirement information respectively, for example, different services are provided for different enterprise users, the service requirements of different enterprises are met, and the use feeling of the enterprise user is improved.

Illustratively, an enterprise user inputs configuration information meeting enterprise requirements through a control device in a data transmission system, further, the control device sends the configuration information to a first end side device or a node in a cloud system, and the first end side device or the node in the cloud system determines requirement information corresponding to a data packet to be transmitted according to the configuration information and the enterprise user.

The configuration information may be information in an optional requirement information list corresponding to different services provided by the data transmission system for the enterprise user, or may also be a correspondence between a QoS requirement independently designed by the user and a quintuple, which is not specifically limited in this embodiment of the present application.

Fig. 7 is a schematic structural diagram of another data transmission system provided in an embodiment of the present application, as shown in fig. 7, an enterprise user may input configuration information through a control device 105, for example, in an application scenario of a cloud game, the configuration information of which the delay of the cloud game 1 is smaller than the delay of the cloud game 2 is input, then the control device 105 sends the configuration information to a controller 104, the controller 104 may send the configuration information to nodes 1 to 3, and further, the nodes 1 to 3 may determine, according to the configuration information and the enterprise user to which a service corresponding to a data packet to be transmitted belongs, demand information corresponding to the data packet to be transmitted. Optionally, it is understood that the first end-side device 101 may also obtain configuration information, so as to implement encapsulation and transmission of data.

Therefore, the embodiment of the application allows enterprises to independently select the QoS requirements, can meet the service requirements of different enterprises, and can improve the flexibility of data transmission and the satisfaction degree of users.

In another example, in a live scenario, the first end-side device 801 may correspond to a terminal device of a viewer, such as a mobile phone, and the second end-side device 802 corresponds to a terminal device or a server of an anchor, specifically, the first end-side device 801 may send a function corresponding to a live service, such as a function of comment, forwarding, leaving a message, privately letter, and like, and further send an identifier determined based on the function and a corresponding data packet to a cloud system, the cloud system selects a part of nodes corresponding to the data packet to be transmitted based on demand information corresponding to the determined identifier, transmits the data packet to the terminal device or the server of the anchor through a transmission path formed by the part of nodes, and the anchor may check comment content, forwarding number, privletter content, and praise number, etc. returned by the mobile phone of the viewer, or the server processes information returned by the mobile phone of the viewer, for example, some bad comments are filtered out, and further, the processed information is returned to the terminal device of the anchor through the on-cloud system again.
