Description

Data transmission method, system, device, electronic equipment and storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a data transmission method, system, device, electronic apparatus, and storage medium.

Background

With the development of communication technology, a service platform (e.g., a server) may provide a data acquisition service for a user, and when the user needs to acquire data, the user may instruct a client to send a data acquisition request to the service platform. Correspondingly, after receiving the data acquisition request sent by the client, the service platform can send the data requested by the client to the client.

In the related art, in order to implement communication between a service platform and a client, a technician may configure a service component for communication with the client in the service platform. The technician can determine the port of the client for communication with the service platform and the format of the data received by the client according to the network protocol of the wired local area network to which the client belongs, and configure the corresponding service assembly in the service platform. And after receiving the data acquisition request, the service platform can establish communication connection with the client through the configured service component according to the configured port. Further, the service platform may send the data requested by the client to the client through the established communication connection according to the configured data format. For example, the service platform may be a video platform, and the video platform may send, through the configured service component, the video resource requested by the client to the client according to the configured data format through the established communication connection.

However, since different clients may belong to different wired local area networks, network protocols of the different wired local area networks are different, that is, different ports where the clients communicate with the service platform, and formats of data received by the clients are different. If the service platform does not configure a service component for sending data to the client in the wired local area network in the server according to the network protocol of a certain wired local area network, the service platform cannot send service data to the client in the wired local area network. As can be seen, in the related art, the application range of the data transmission method is narrow.

For example, the first service server may be: among the service servers communicatively connected to the first client, the service server closest to the first client is the service server closest to the first client. Alternatively, the first service server may be: a service server specified in the service servers communicatively coupled to the first client.

When the user needs to acquire service data, an acquisition instruction (which may be referred to as a first acquisition instruction) for the first service data may be input to the first client. Correspondingly, after the first client receives the first acquisition instruction, the user needs to acquire the first service data, and the first client can send a first acquisition request for acquiring the first service data to the first service server through a first communication connection with the first service server. For example, the first client sends a first acquisition request carrying an identification of the first service data to the first service server. The identification of the first service data may be a name of the first service data. The first communication connection is a data path for communication between the first client and the first service server.

By way of example, the data transmission system may be a system for video asset distribution. When the user needs to watch the video, the user can click an operation button for playing the video in the display interface of the first client. Accordingly, when the first client detects the click operation of the user on the operation button for playing the video, which indicates that the user needs to watch the video, the first client may send a first acquisition request for the video indicated by the user to the first service server.

The plurality of service servers in the data transmission system can be connected according to a tree network structure, namely, the topology structure of the data transmission system is the tree network structure. In a data transmission system of a tree network structure, a plurality of service servers are divided into a plurality of layers, and each layer comprises at least one service server; each service server is in communication connection with a service server in an adjacent layer to the layer to which the service server belongs. A service server in any layer of the first service server data transmission system.

Illustratively, for the data transmission system shown in fig. 1, the data transmission system includes two layers of service servers, and the first layer includes 3 service servers 102, specifically, a service server 1021, a service server 1022, and a service server 1023. The second tier includes 3 service servers 104, specifically service server 1041, service server 1042, and service server 1043.

Accordingly, the first service server may be a service server in the first layer, that is, the first service server may be any one of the service server 1021, the service server 1022, and the service server 1023. The first client may be communicatively connected to a first traffic server. For example, if the first service server is the service server 1021, the first client may be any one of the client 1011, the client 1012, and the client 1013. Alternatively, the first service server may be a service server in the second layer, that is, the second service server may be any one of the service server 1041, the service server 1042, and the service server 1043. The first client may be communicatively connected to a first traffic server. For example, if the first service server is service server 1041, the first client may be client 1031.

The first service server may receive the first acquisition request, and perform corresponding processing according to the received first acquisition request.

In some embodiments, the first client may establish a first communication connection with the first traffic server as follows. On the basis of fig. 2, referring to fig. 3, before step S201, the following steps may be further included:

s205: the first client sends a connection request carrying a port identification of a first port of the first service server to the first service server.

S206: the first service server receives a connection request which is sent by the first client and carries a port identifier of a first port of the first service server.

S207: if the first port of the first service server is in an idle state, the first service server sends a first response message carrying a port identifier of the first port to the first client; if the first port of the first service server is in a non-idle state, the first service server sends a second response message carrying the port identification of the second port which is currently idle to the first client.

S208: after receiving a first response message sent by a first service server, the first client establishes a first communication connection with the first service server through a first port of the first service server; after receiving the second response message sent by the first service server, the first client establishes a first communication connection with the first service server through a second port of the first service server.

The port of the service server is a data interface through which the service server communicates with other devices. The first service server can communicate with other service servers and clients through ports. The first service server may include a plurality of ports, and the first service server may communicate with a plurality of other devices through one port, and the number of devices that communicate through different ports may be different.

After determining the first service server in the data transmission system, the first client may send a connection request carrying a port identification of the first port of the first service server to the first service server. The connection request also indicates: the first client requests to establish a first communication connection with the first service server through a first port of the first service server.

After receiving the connection request sent by the first client, the first service server can determine that the first client requests to establish a first communication connection with the first service server through the first port according to the port identifier of the first port carried in the connection request. Further, the first service server may determine an operational state of the first port. The working state of the first port indicates: the number of communication connections established by the first service server with other devices through the first port.

The working states of the first port include an idle state and a non-idle state, the idle state representing: the number of communication connections established between the first service server and other devices through the first port is smaller than the preset number; the non-idle state represents: the number of communication connections established between the first service server and other devices through the first port is not smaller than the preset number.

If the working state of the first port is an idle state, which means that the number of communication connections established through the first port of the first service server is small, if the first client establishes communication connections with the first service server through the first port, the first service server can timely receive a first acquisition request sent by the first client.

Thus, the first service server may send a first response message carrying the port identification of the first port to the first client, the first response message also representing: the first traffic server may be communicatively coupled to the first client via a first port.

After the first client receives the first response message sent by the first service server, the first client can establish a first communication connection with the first service server through the first port of the first service server.

For example, the first client sends a SYN (Synchronize Sequence Numbers, synchronization sequence number) data packet to the first service server according to the received port identifier of the first port sent by the first service server; after receiving the SYN packet, the first service server sends an ACK (Acknowledge character, acknowledgement character) packet to the first client through the first port, where the ACK packet indicates that the first client received the SYN packet; after receiving the ACK data packet sent by the first service server, the first client sends the ACK data packet to the first service server through the first port, and after receiving the ACK data packet sent by the first client, the first service server establishes the first communication connection successfully.

If the working state of the first port is a non-idle state, which means that the number of communication connections established through the first port of the first service server is large, if the first client establishes communication connections with the first service server through the first port, the first service server cannot timely receive the first acquisition request sent by the first client, which results in reduced data transmission efficiency.

Therefore, the first service server may determine the second port whose working state is the idle state, and send a second response message carrying the port identifier of the second port to the first client, where the second response message also indicates: the working state of the second port of the first service server is an idle state, and the first service server can be in communication connection with the first client through the second port.

After the first client receives the second response message sent by the first service server, the first client can establish a first communication connection with the first service server through the second port of the first service server. The first communication connection between the first client and the first service server is established through the second port of the first service server, and similar to the manner in which the first client establishes the first communication connection between the first client and the first service server through the first port of the first service server, reference may be made to the related description.

In some embodiments, the first client may establish a communication connection with the first service server when first communicating with the first service server. Since the communication connection between the first client and the first service server may be interrupted, in order to ensure that communication between the first client and the first service server is enabled, the first client may also establish a communication connection with the first service server when a preset period is reached. Alternatively, the first client may establish a communication connection with the first service server before each sending the first acquisition request to the first service server.

Based on the above processing, the first service server may send, to the first client, a response message carrying the port identifier of the port currently in the idle state according to the working state of each port of the first service server, and further, the first client establishes a first communication connection with the first service server according to the port identifier sent by the first service server. That is, according to the state of the port of the first service server, the port selected when the first client establishes a communication connection with the first service server is adjusted. Accordingly, the first service server is not required to establish the first communication connection with the first client according to the configured port, and a service component for sending data to the first client is not required to be configured in the first service server, so that the first service server can send service data to a plurality of clients, and the application range of the data transmission method can be improved.

For step S203 and step S204, after receiving the first acquisition request, the first service server may query whether the first service server locally stores the first service data according to the identifier of the first service data carried in the first acquisition request.

If the first service data is stored locally in the first service server, the first service server may send the first service data to the first client over the first communication connection. The first service data stored locally by the first service server may be sent to the first service server by other service servers in the data transmission system.

Correspondingly, the first client may receive the first service data sent by the first service server. After the first client receives the first service data, the first service data may be presented to the user. For example, if the first service data is video, the video may be played in the first client for browsing by the user.

The first service server may forward the first acquisition request to the second service server if the first service data is not stored locally at the first service server. The second service server is: any one of service servers of a layer of service servers above a first service server in a data transmission system. For example, the second service server may be: and in the service servers of the upper layer of the first service server in the data transmission system, the service server closest to the first service server is selected.

For example, with respect to the data transmission system shown in fig. 1, if the first service server is the service server 1021, the second service server may be any one of the service server 1041, the service server 1042, and the service server 1043. If the first service server is the service server 1022, the second service server may be any one of the service server 1042 and the service server 1043. If the first service server is service server 1023, the second service server may be service server 1043.

After the first service server receives the first acquisition request, if the first service data is not stored locally in the first service server, the first service server may forward the first acquisition request to the second service server.

After the second service server receives the first acquisition request, whether the first service data is stored in the second service server locally can be queried according to the identifier of the first service data carried in the first acquisition request.

The second service server may send the first service data to the first service server if the second service server has the first service data stored locally. If the second service server does not store the first service data locally, the second service server may also forward the first acquisition request to a service server in a layer above the second service server, so as to acquire the first service data from the service server in the layer above the second service server, and so on, until the second service server acquires the first service data, and then send the first service data to the first service server.

Correspondingly, after receiving the first service data, the first service server sends the first service data to the first client, and then the first client can receive the first service data.

In some embodiments, after the first service server receives the first service data sent by the second service server, the first service data may be stored locally on the first service server. Subsequently, if other clients in communication connection with the first service server request the first service data from the first service server, the first service server can directly send the locally stored first service data to the other clients without acquiring the first service data from the other service servers in the data transmission system, so that the data transmission efficiency can be improved.

And when the first service server does not locally store the first service data, the first service server can acquire the first service data from the second service server, and then the first service server can send the first service data to the first client, so that the first client can acquire the first service data, and the user requirement is met. In addition, the data transmission system can carry out data distribution according to the tree network structure, so that the data distribution capacity of the data transmission system is improved, and the throughput of the data transmission system is improved. Therefore, the data transmission system may also be referred to as a high-throughput high-capacity data transmission system.

In some embodiments, if there is no service server on the upper layer of the first service server in the data transmission system, for example, for the data transmission system shown in fig. 1, when the first service server is the service server 1041, there is no service server on the upper layer of the first service server. If the service server 1041 does not store the first service data locally, the service server 1041 may send a notification message to the first client indicating that the first service data is not acquired.

In some embodiments, there are multiple transmission paths between the first traffic server and the second traffic server, each transmission path including multiple forwarding servers. The first service server may forward the first acquisition request to the second service server in the following manner.

In one implementation, for each transmission path between the first service server and the second service server, the first service server may obtain an operation state of each forwarding server included in the transmission path. The first service server may determine a transmission path in which the forwarding server included in the plurality of transmission paths operates normally, and select any transmission path from the determined transmission paths. Further, the first service server forwards the first acquisition request to the second service server according to the selected transmission path.

In another implementation, step S203 may include the following steps:

step 1: the first service server determines the shortest transmission path which is included in a plurality of transmission paths between the first service server and the second service server and is operated normally by the forwarding server as a target transmission path.

Step 2: and the first service server forwards the first acquisition request to the second service server according to the target transmission path.

For each transmission path between the first service server and the second service server, the first service server may determine a transmission path (may be referred to as an alternative transmission path) in which the forwarding server included operates normally from among the plurality of transmission paths. Then, the first service server may select the shortest alternative transmission path from the determined alternative transmission paths as a target transmission path, and forward the first acquisition request to the second service server through the target transmission path.

For each of the alternative transmission paths, the first service server may select, as the target transmission path, the alternative transmission path having the smallest sum of distances between the included forwarding servers from among the alternative transmission paths. Alternatively, the first service server may select, as the target transmission path, the candidate transmission path having the smallest number of forwarding servers included.

Based on the above processing, there are multiple transmission paths between the first service server and the second service server, where the first service server can determine a target transmission path from the multiple transmission paths, and forward the first acquisition request to the second service server according to the target transmission path, where the target transmission path is shortest, and the included transmission paths in which the forwarding servers operate normally, so that it is possible to avoid situations that the first service server and the second service server cannot communicate due to failure of part of the forwarding servers, and further cause reduction in data transmission efficiency, and thus, normal operation of the data transmission system can be ensured. That is, the data transmission can be performed by a non-blocking network data processing mode, so that the stability of the data transmission system can be improved.

In some embodiments, in order to improve the efficiency of data transmission and the stability of the data transmission system, when the second service server sends service data to the first service server, a transmission path which is shortest and includes a forwarding server and operates normally may also be determined from a plurality of transmission paths, and the first service data is sent to the first service server through the selected transmission path.

Based on the above processing, since the target transmission path is: the shortest alternative transmission path among the alternative transmission paths exists between the first service server and the second service server, so that the first service server and the second service server communicate through the target transmission path, and the time required by the first service server to acquire the first service data from the second service server can be reduced. Furthermore, the time required by the first client to acquire the first service data can be reduced, and the delay of data transmission can be reduced.

In some embodiments, the data transmission system may further include a third service server communicatively coupled to the first service server; the network structure of the data transmission system is a tree network structure; the third service server is a service server of a layer next to the first service server. The method may further comprise the steps of:

step 1: and receiving a second acquisition request sent by the third service server.

The second acquisition request is used for acquiring second service data; the second acquisition request is a second client in the data transmission system and is sent to the third service server through a second communication connection with the third service server; the second communication connection is: and after the second client sends a connection request to the third service server, the connection request is established according to the port identifier returned by the third service server.

Step 2: and if the first service server locally stores the second service data, the first service server sends the second service data to the third service server so that the third service server sends the second service data to the second client through the second communication connection after receiving the second service data, and the second client receives the second service data.

The plurality of service servers in the data transmission system can be connected according to a tree network structure, namely, the topology structure of the data transmission system is the tree network structure. For each service server in the data transmission system, the data transmission system may further include a service server of a layer next to the service server.

The third service server is: any one of service servers of a next layer of service servers of a first service server in the data transmission system. For example, the third service server may be: and in the service servers of the next layer of the first service server in the data transmission system, the service server closest to the first service server is selected.

Referring to fig. 4 on the basis of fig. 1, fig. 4 is a second architecture diagram of a data transmission system according to an embodiment of the present invention. The service servers in the data transmission system may be divided into three layers, and the first layer includes a plurality of service servers 106, and in this embodiment, the first layer includes 3 service servers 106 as an example. The second layer includes a plurality of service servers 102, and in this embodiment, the second layer includes 3 service servers 102 as an example. The third layer includes a plurality of service servers 104, and in this embodiment, the third layer includes 3 service servers 104 as an example. The data transmission system also includes clients in communication with the business servers of the layers.

Wherein the first tier comprises 3 service servers 106, the service servers 106 of the first tier are in communication with the clients 105. Specifically, the service server 1061 communicates with the client 1051, the client 1052, and the client 1053; the traffic server 1062 communicates with

clients

1052 and 1053; a traffic server 1063 communicates with the client 1053. The second tier comprises 3 service servers 102, the third tier comprises 3 service servers 104, the service servers 102 of the second tier are in communication with the clients 101, and the service servers 104 of the third tier are in communication with the clients 103. The manner in which the service server 102 communicates with the client 101 and the manner in which the service server 104 communicates with the client 103 are referred to in the description of the foregoing embodiments.

Wherein, the service server 1021 next layer of service servers includes: a service server 1061; the service server 1021 is a layer of service servers including: service server 1041, service server 1042, and service server 1043. If the first service server is 1021, the third service server is a service server 1061, and the second service server is any one of a service server 1041, a service server 1042, and a service server 1043. The second client is any one of the client 1051, the client 1052, and the client 1053.

The service server 1022 further includes: a service server 1062 and a service server 1063; the service servers of the upper layer of the service server 1022 include: a service server 1042 and a service server 1043. If the first service server is 1022, the third service server is any one of the

service servers

1062 and 1063, and the second service server is any one of the

service servers

1042 and 1043. The second client is either one of the client 1052 and the client 1053.

The service server 1023 next layer service server includes:

service servers

1061, 1062, and 1063; the service server of the upper layer of the service server 1023 includes: service server 1043. If the first service server is 1023, the third service server is any one of service server 1061, service server 1062, and service server 1063, and the second service server is service server 1043. The second client is client 1053.

When the user needs to acquire service data, an acquisition instruction (which may be referred to as a second acquisition instruction) for the second service data may be input to the second client. Correspondingly, after the second client receives the second acquisition instruction, the second client indicates that the user needs to acquire the second service data, and the second client can send a second acquisition request for acquiring the second service data to the third service server through second communication connection with the third service server. For example, the second client sends a second acquisition request carrying an identification of the second service data to the third service server. The identification of the second service data may be a name of the second service data. The second communication connection is a data channel for communication between the second client and the third service server. The procedure for establishing the second communication connection is similar to the procedure for establishing the first communication connection in the previous embodiment, and reference is made to the description of the previous embodiment.

After the third service server receives the second acquisition request, if the third service server locally stores the second service data, the third service server may send the second service data to the second client through the second communication connection.

If the third service server does not store the second service data locally, the third service server may forward the second acquisition request to the first service server.

After the first service server receives the second acquisition request, if the first service server locally stores the second service data, the first service server may send the second service data to the third service server. The first service server may acquire the second service data from a service server (e.g., a second service server) of a layer above the first service server if the first service server does not store the second service data locally. After the first service server acquires the second service data, the second service data may be sent to the third service server.

After receiving the second service data, the third service server may send the second service data to the second client through the second communication connection. Accordingly, the second client may receive the second service data.

Based on the above processing, when the third service server does not locally store the second service data, the third service server may acquire the second service data from the first service server, and further, the third service server may send the second service data to the second client, so that the second client may acquire the second service data, thereby meeting the user requirement.

In some embodiments, after the third service server receives the second service data sent by the first service server, the second service data may be stored locally on the third service server. Subsequently, if the other clients communicatively connected with the third service server request the second service data from the third service server, the third service server can directly send the locally stored second service data to the other clients without acquiring the second service data from the other service servers in the data transmission system, so that the data transmission efficiency can be improved.

In some embodiments, there are multiple transmission paths between the third traffic server and the first, each transmission path including multiple forwarding servers. In order to improve the efficiency of data transmission and the stability of the data transmission system, the third service server may select a transmission path which is shortest from a plurality of transmission paths and includes a forwarding server that operates normally, and forward the second acquisition request to the first service server through the selected transmission path. And before the first service server sends the second service data to the third service server, the first service server may determine a transmission path which is shortest from a plurality of transmission paths and includes a forwarding server that operates normally. Further, the second service data is transmitted to the third service server through the selected transmission path.

In some embodiments, to improve the efficiency of data transmission, multiple threads may be started in the first service server; each thread is for processing acquisition requests sent by respective clients communicatively coupled to the first service server. For each thread in the first service server, the thread runs in a designated CPU core corresponding to the thread in the first service server. On the basis of fig. 2, referring to fig. 5, the following steps may be included in step S202:

s2021: and the first service server receives a first acquisition request sent by the first client through the first communication connection through a currently idle target thread in the plurality of threads.

Accordingly, step S203 may include the steps of:

s2031: if the first service data is stored locally in the first service server, the first service server sends the first service data to the first client through the first communication connection by the target thread; if the first service data is not stored locally in the first service server, forwarding a first acquisition request to the second service server so that the second service server sends the first service data to the first service server; and receiving the first service data sent by the second service server, and sending the first service data to the first client through the first communication connection by the target thread.

A plurality of threads are started in the first service server, and the number of the started threads can be set according to requirements. For each thread, the technician may bind the thread to, i.e., run on, a CPU (Central Processing Unit ) core in the first service server. Each thread running on the same CPU core equally divides the operation resource and the memory resource of the CPU core, that is, each thread can use the operation resource and the memory resource of the CPU, so that the problem that the thread cannot timely process the received request due to insufficient operation resource or memory resource of a certain thread can be avoided, and further the efficiency of data transmission can be improved.

Each thread is for processing acquisition requests sent by respective clients communicatively coupled to the first service server. For each thread started in the first service server, the thread can process the acquisition requests sent by a plurality of clients.

The first service server may determine a currently idle thread from the plurality of threads, and obtain a target thread. If the currently idle thread in the first service server is one, the first service server may determine the idle thread as the target thread. If the number of currently idle threads in the first service server is multiple, the first service server may determine any one of the multiple currently idle threads as the target thread.

Further, the first service server may receive the first acquisition request sent by the first client through the target thread, and if the first service data is locally stored in the first service server, the first service server may send the first service data to the first service server through the target thread. If the local storage of the first service server does not store the first service data, the first service server can acquire the first service data from other service servers through the target thread, and send the first service data to the first client through the target thread.

Based on the processing, a plurality of threads are started in the first service server, and the received acquisition request is processed through the plurality of threads, so that the efficiency of data transmission can be improved. That is, the efficiency of data transmission can be improved by means of load balancing processing.

In some embodiments, to increase the efficiency of data transmission, for each service server in the data transmission system, multiple threads may be started in the service server, and each thread started in the service server is used to process the acquisition request received by the service server.

In some embodiments, to enable management of individual service servers in the data transmission system, the data transmission system may further include a management server. On the basis of fig. 2, referring to fig. 6, after step S204, the method further comprises the steps of:

s209: the first service server counts the data volume of the received service data, the data volume of the transmitted service data and the data flow information of the service data in a preset time period, and a counting result is obtained.

Wherein the data flow information indicates: the flow direction of the service data sent by the first service server and the flow direction of the service data received by the first service server.

S210: the first service server sends a statistical result to the management server, so that the management server sends a first adjustment instruction to the first service server when the statistical result meets a preset adjustment condition; and when the statistical result does not meet the preset adjustment condition, sending a second adjustment instruction to the first service server.

S211: after receiving the first adjustment instruction, the first service server forwards the third acquisition request to a fourth service server currently idle in the data transmission system if the third acquisition request sent by the third client is received, so that the fourth service server processes the third acquisition request; after receiving the second adjustment instruction, if a third acquisition request sent by a third client is received, acquiring third service data, and sending the third service data to the third client so that the third client receives the third service data.

The third acquiring request is used for acquiring third service data.

The first service server sends the data volume of the service data within a preset time period, wherein the data volume comprises: and the first service server transmits the data quantity to each service server and each client in a preset time period. The first service server receives the data volume of the service data within a preset time period, wherein the data volume comprises: and the data volume sent to the first service server by each service server received by the first service server in the preset time period.

The data flow information indicates the flow direction of the service data sent by the first service server and the flow direction of the service data received by the first service server. That is, to which service servers, clients, the first service server sent the service data, and which service servers received the service data sent by the first service server.

When the statistics period is reached, the first service server can count the data volume of the service data received by the first service server, the data volume of the transmitted service data and the data flow information within a preset time period, and a statistics result is obtained. The statistical period of the first service server can be set according to actual requirements. In order to improve the accuracy of the management server in managing the service servers in the data transmission system, a smaller statistical period may be set, for example, the statistical period may be 1 minute; in order to reduce the consumption of the operation resources of the first service server and reduce the performance degradation of the first service server, a larger statistics period may be set, for example, the statistics period may be 5 minutes.

Or the management server can send a monitoring request to the first service server, and after the first service server receives the monitoring request sent by the management server, the first service server can count the data volume of the service data received by the first service server, the data volume of the sent service data and the data flow information within a preset time period, so as to obtain a statistical result.

In one implementation manner, the first service server may count the data amount of the service data sent by the first service server to each client, and the data amount of the service data sent by the first service server to each service server, so as to obtain the data amount sent by the first service server in a preset time period. The first service server may further count the data amount of the service data sent by each received service server, to obtain the data amount received by the first service server in the preset time period.

In another implementation manner, the first service server may calculate a sum of data amounts of service data sent by the first service server to each client and each service server, to obtain a total data amount of service data sent by the first service server. The first service server may further calculate a sum of data amounts of the service data sent by each service server received by the first service server, to obtain a total data amount of the service data received by the first service server.

Further, the first service server transmits the statistics to the management server. Correspondingly, the management server can receive the statistical result of the first service server, and judge whether the statistical result sent by the first service server meets the preset adjustment condition according to the statistical result sent by the first service server, so as to make corresponding processing according to the judgment result.

The preset adjustment condition may be determined based on the data amount of the received service data, the data amount of the transmitted service data, and/or the data flow direction information of the first service server in the preset time period.

In one implementation, the statistics include: the total data amount of the service data transmitted by the first service server and the total data amount of the service data received by the first service server. Correspondingly, the preset adjustment conditions may be: at least one of the total data amount of the service data received by the first service server in the preset time period and the total data amount of the service data transmitted by the first service server in the preset time period exceeds a first preset threshold.

Or the first service server determines the sum of the number of clients in communication connection with the first service server and the number of service servers as the number of other devices in communication connection with the first service server according to the data flow information of the service data received in the preset time period. Correspondingly, the preset adjustment conditions may be: the number of other devices communicatively connected to the first traffic server is greater than a second preset threshold.

In another implementation manner, the first service server determines a client and a service server which are in communication connection with the first service server according to data flow direction information of service data received in a preset time period, and determines data amounts sent by the first service server to each service server and the client in the preset time period and data amounts sent by each service server received by the first service server in the preset time period. That is, the statistics include: the data volume sent by the first service server to each service server and the client in the preset time period, and the data volume sent by each service server received by the first service server in the preset time period.

Correspondingly, the preset adjustment conditions may be: the data volume of the service data sent by the first service server to the preset number of other devices is larger than a third preset threshold value, and/or the data volume of the service data sent by the preset number of service servers received by the first service server in a preset time period is larger than a fourth preset threshold value. The other devices include other service servers and clients communicatively connected to the first service server.

If the statistical result of the first service server meets the preset adjustment condition, which indicates that the current data volume transmitted by the first service server is larger, if the first service server continues to process the acquisition request, the first service server may need to wait for a long time to be processed after receiving the acquisition request, thereby reducing the data transmission efficiency. Thus, the management server may send the first adjustment instruction to the first service server.

After the first service server receives the first adjustment instruction, if the first service server receives the third acquisition request sent by the third client, the first service server may forward the third acquisition request sent by the third client to a currently idle service server (i.e., a fourth service server) in the data transmission system, that is, the fourth service server in the data transmission system processes the third acquisition request. The fourth service server is: among the service servers that have been communicatively connected to the third client, the currently idle service server.

And if the first service server receives the third acquisition request forwarded by other service servers in the data transmission system to the first service server, the first service server may forward the third acquisition request to the fourth service server, that is, the fourth service server processes the third acquisition request, so as to avoid the reduction of the efficiency of data transmission.

If the statistical result sent by the first service server does not meet the preset adjustment condition, the statistical result indicates that the current data volume transmitted by the first service server is smaller, and if the first service server continues to process the acquisition request, the first service server can process the acquisition request in time. Thus, the management server may send the second adjustment instruction to the first service server.

After the first service server receives the second adjustment instruction, if the first service server receives a third acquisition request sent by the third client, the first service server can continue to process the third acquisition request, that is, the first service server can acquire third service data indicated by the third acquisition request, and send the third service data to the third client.

Based on the above processing, the management server is in communication connection with other service servers in the data transmission system, monitors the data volume and the data flow information of the data transmission system, and manages the data transmission system according to the monitoring result, that is, feeds back the monitoring result, so that the operation efficiency of the data transmission system can be improved. That is, the problem that the service server cannot process the received request in time due to the large data volume currently transmitted by a certain service server can be avoided by a load balancing processing mode, so that the efficiency of data transmission can be improved.

In some embodiments, the management server may also determine, from the service servers, a fifth service server having a data amount of the received service data and a data amount of the transmitted service data that are both less than a fifth preset threshold according to the statistics result sent by each service server in the data transmission system, and send a shutdown instruction to the fifth service server. After the fifth service server receives the shutdown instruction, the fifth service server may be shutdown, for example, the fifth service server may no longer receive the acquisition request sent by the service server and the client in the data transmission system. And, the management server may transmit a notification message indicating that the fifth service server no longer processes the acquisition request to other service servers and clients in the data transmission system. Correspondingly, after the other service servers and the client side receive the notification message sent by the management server, the fifth service server can be determined to not process the acquisition request any more, and the other service servers and the client side can not send the acquisition request to the fifth service server any more, so that the operation resources consumed by the data transmission system can be reduced, the structure of the data transmission system is optimized, and the operation efficiency of the data transmission system is improved.

The specific manner in which data transmission is performed based on the data transmission system of fig. 7 is described with reference to the method embodiment of fig. 8.

Referring to fig. 8, fig. 8 is a fifth flowchart of a data transmission method according to an embodiment of the present invention. The data transmission method applies a data transmission system, the data transmission system comprises: the system comprises a first client, a first service server, a second service server and a sixth service server. The first business server may be any one of the data distribution service 7011, the data distribution service 7012, the data distribution service 7013, and the data distribution service 7014 in fig. 7; the first client may be a client 704 communicatively connected to the first service server; the second service server may be a data distribution service 702 communicatively coupled to the first service server; the sixth business server may be a data distribution service 7031.

The method may comprise the steps of:

s801: the first client sends a first acquisition request to the first service server through a first communication connection with the first service server.

In this step, when the user needs to acquire service data, a first acquisition instruction for the first service data may be input to the first client. After receiving the first acquisition instruction, the first client may send a first acquisition request for acquiring the first service data to the first service server through a first communication connection with the first service server. The first communication connection is a data path for communication between the first client and the first service server.

S802: the first service server receives a first acquisition request sent by a first client.

In this step, after the first service server receives the first acquisition request, it may be queried whether the first service server locally stores the first service data. If the first service data is stored locally in the first service server, the first service server may send the first service data to the first client over the first communication connection. If the first service data is not stored locally at the first service server, step S803 is performed.

S803: the first service server forwards the first acquisition request to the second service server without storing the first service data locally.

S804: the second service server receives a first acquisition request sent by the first service server.

In this step, after the second service server receives the first acquisition request, it may query whether the second service server locally stores the first service data. The second service server may send the first service data to the first service server if the second service server has the first service data stored locally. If the first service data is not stored locally at the second service server, step S805 is performed.

S805: the second service server forwards the first acquisition request to the sixth service server without storing the first service data locally.

S806: the sixth service server receives the first acquisition request sent by the second service server.

In this step, after the sixth service server receives the first acquisition request, it may query whether the sixth service server locally stores the first service data, and perform corresponding processing according to the query result.

S807: the sixth service server transmits the first service data to the second service server.

In this step, if the first service data is stored locally at the sixth service server, the sixth service server may transmit the first service data to the second service server. If the first service data is not stored locally at the sixth service server, the sixth service server may acquire the first service data from the other service servers and then transmit the first service data to the second service server.

S808: the second service server receives the first service data sent by the sixth service server.

S809: the second service server transmits the first service data to the first service server.

S810: the first service server receives first service data sent by the second service server.

S811: the first service server sends first service data to the first client through the first communication connection.

S812: the first client receives first service data sent by the first service server.

Based on the above processing, the first service server can send service data to each client through communication connection with the client, that is, can realize that the first service server sends service data to a plurality of clients, reduces difficulty in establishing communication connection, reduces difficulty in integrating data channel capacity, reduces coupling between the first service server and the clients, can improve application range of a data transmission method, and reduces cost of configuration hardware. The data transmission system comprises a plurality of layers of servers, and when the service server receives the acquisition request of the client, if the service server does not locally store the service data requested by the client, the service server can acquire the service data requested by the client from the service server of the upper layer of the service server and send the requested service data to the client, so that the client can acquire the service data requested by the client, and the user requirement is met. In addition, the data transmission system is in a tree network structure, so that data distribution can be performed according to the tree network structure, and the efficiency of the data transmission system, namely the data distribution capacity of the data transmission system, can be improved.
