Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of a data transmission method according to the present application, where the data transmission method includes the following steps:
step S201, receiving information to be transmitted sent by a sending end, and obtaining a first network parameter of the sending end according to the information to be transmitted.
In the present embodiment, the execution body is a data transmission device, and for convenience of description, a device is hereinafter referred to as a data transmission device. The apparatus may be any terminal device having data processing capabilities.
The cluster is deployed with a plurality of node devices, defined as receivers, with which the apparatus is communicatively connected. The cluster may be a card cluster.
The client, as a transmitting end, transmits information to the device, the information being defined as information to be transmitted. After receiving the information to be transmitted of the sending end, the device acquires the first network parameter of the sending end based on the information to be transmitted. The information to be transmitted carries, for example, an IP address of the transmitting end, and the device uses the IP address as the first network parameter.
Step S202, obtaining second network parameters of each first receiving end, and determining a first distance between the sending end and each first receiving end according to the first network parameters and each second network parameters.
When each node device in the cluster is deployed, corresponding network parameters are set, the network parameters of each node device can be stored in any node device, and the device sends a request to the node device, so that the network parameters of each node device are obtained. In this embodiment, the node device is defined as a first receiving end, and the network parameter of the node device is defined as a second network parameter.
After obtaining the first network parameters and the second network parameters, the device may determine a distance between the transmitting end and each first receiving end based on the first network parameters and each second network parameter, where the distance is defined as a first distance.
The first network parameter and the second network parameter may be network segments, and the network segments of the respective first node devices are stored in a b+ number, where b+ refers to a binary tree. The device finds a second network parameter close to the first network parameter on the B+ number, and a first receiving end corresponding to the second network parameter close to the first network parameter is defined as a second receiving end. For example, the network segment of the transmitting end is close to the network segment of a certain first receiving end.
Specifically, when the node device is deployed, the position of the node device is determined, the position and the network parameter of the node device are stored in an associated manner, and the network parameter of the client also has a corresponding position. The device determines a distance between the transmitting end and each first receiving end based on the position associated with the first network parameter and the position associated with each second network parameter on the B+ tree, wherein the distance is defined as a first distance.
Step S203, determining a plurality of second receiving ends in each first receiving end according to the first distance, and sending test information to each second receiving end, where the first distance corresponding to the second receiving end is smaller than the first preset distance.
The device determines a plurality of second receiving ends in each first receiving end based on the first distance, wherein the first distance corresponding to the second receiving ends is smaller than the first preset distance, namely the first receiving end corresponding to the first distance smaller than the first preset distance is determined as the second receiving end.
The distance between the second receiving end and the device is smaller, and thus the time delay between the second receiving end and the device may also be smaller. In order to accurately determine the time delay between the second receiving end and the device, the device sends test information to each second receiving end. The test information may be a heartbeat packet, that is, the receiving end receives the heartbeat packet and needs to feed back response information to the device.
Step S204, receiving response information fed back by each second receiving end based on the test information, and determining target time delay between the sending end and the second receiving end according to the receiving time point of the response information and the sending time point of the test information.
And the second receiving end feeds back response information to the device after receiving the test information. The device can determine the target time delay between the second receiving end and the transmitting end for transmitting the response information based on the receiving time point of the response information and the transmitting time point of the test information. The device sends test information to the receiving end a, and the sending time point of the test information is 9:00:01, the time point of the device receiving the response information sent by the receiving end a is 9:00:03, the target time delay between the receiving end a and the device= (3 s-1 s)/2=1s, i.e. the time delay between the receiving end a and the device is 1 second.
In step S205, a target receiving end is determined in each second receiving end according to the target time delay, the information to be transmitted is sent to the target receiving end, the link between the sending end and the target receiving end is set as a first fixed sending link, the target time delay of the target receiving end is smaller than the preset time delay, and the first fixed sending link is used for indicating to send the data of the sending end to the target receiving end.
The target time delay is arranged between each second receiving end and the device, namely, each second receiving end corresponds to one target time delay, the device can determine the target receiving end from the second receiving ends based on the target time delay, and the target time delay of the target receiving end is smaller than the preset time delay. In an example, the second receiving end corresponding to the target delay smaller than the preset delay may be used as the target receiving end. In another example, the apparatus takes a second receiving end corresponding to the minimum target delay as a target receiving end.
After determining the target receiving end, the device sends the information to be transmitted to the target receiving end, and a first fixed sending link is set on a link between the sending end and the target receiving end, wherein the first fixed sending link is used for indicating to send the data of the sending end to the target receiving end, namely the device can directly send the information of the receiving end to the target receiving end later. The device can store the identification of the transmitting end and the identification of the target receiving end in an associated mode, and the first fixed transmission link is stored in the running mode.
In this embodiment, the method includes receiving information to be transmitted sent by a transmitting end, acquiring first network parameters of the transmitting end according to the information to be transmitted, acquiring second network parameters of each first receiving end, determining a distance between the transmitting end and each first receiving end according to the first network parameters and each second network parameter, determining a first receiving end smaller than a preset distance as a second receiving end, sending test information to each second receiving end, receiving response information fed back by each second receiving end, determining a target time delay corresponding to the second receiving end based on a receiving time point of the response information and a sending time point of the test information, determining a second receiving end corresponding to the target time delay smaller than the preset time delay as a target receiving end, and finally sending the information to be transmitted to the target receiving end. In this embodiment, the distance between the transmitting end and each first receiving end is determined through the network parameters of the transmitting end and the first receiving ends, then the second receiving end closer to the transmitting end is found, and then the target receiving end with smaller time delay is determined from a plurality of second receiving ends based on the time delay of the second receiving ends, so that the information of the transmitting end can be transmitted to the target receiving end with smaller time delay, and the link between the transmitting end and the target receiving end is fixed, so that the information of the transmitting end is directly transmitted to the target transmitting end, and the timeliness of the information is improved.
Referring to fig. 3, fig. 3 is a second embodiment of the data transmission method according to the present application, based on the first embodiment, step S203 includes:
step S301, obtaining a network segment range of each cluster partition in the cluster.
In this embodiment, the cluster includes a plurality of cluster partitions, each of which is provided with a plurality of node devices, and each of the node devices has a network segment. In addition, the network segments of the respective node devices in the cluster partition are proximate, and thus, the network segments of the respective node devices within the cluster partition constitute the network segment range of the cluster partition. The network segment ranges may be stored in association with an identification of the cluster partition. The device acquires the network segment range of each cluster partition in the cluster based on the stored information.
Step S302, determining a second distance between the transmitting end and each cluster partition according to the first network segment and the lower limit network segment value of each network segment range, wherein the first network parameter comprises the first network segment.
The network segment range has an upper limit network segment value and a lower limit network segment value, and the device can determine a second distance between the sending end and each cluster partition through the first network segment of the sending end and the lower limit network segment value of each cluster partition, wherein the second distance is the shortest distance between the sending end and each cluster partition. For example, the lower-limit segment value corresponds to one location, and the first segment of the sender corresponds to one location, so that the second distance between the sender and the cluster partition can be calculated by two locations. The first network parameter includes a first network segment, and the device may acquire the first network segment through an IP address of the transmitting end.
Step S303, determining a target partition in each cluster partition according to a second distance, wherein the second distance corresponding to the target partition is smaller than a second preset distance.
And after determining the second distance corresponding to each cluster partition, the device determines the cluster partition corresponding to the second distance smaller than the second preset distance as the target partition. Or determining the cluster partition corresponding to the minimum second distance as the target partition.
Step S304, each node device of the target partition is determined to be a first receiving end, and a second network segment of each first receiving end is acquired, wherein the second network parameters comprise the second network segments.
After determining the target partition, the device determines each node device in the target partition as a first receiving end, and then acquires a second network segment of each first receiving end, that is, the second network parameters of the first receiving ends comprise the second network segment.
After determining the second network segment of the first receiving end, the device determines the first position of the transmitting end based on the first network segment, that is, acquires the position associated with the first network segment as the first position. The device determines a second position of the second receiving end based on the second network segment, namely, the position associated with the second network segment is obtained as the second position, and the device determines the position between the first receiving end and the sending end through the first position and the second position. The linear distance between the first position and the second position is the distance between the two positions.
In an example, node devices of the cluster partition process information of different topics, e.g. node device 1 is responsible for processing messages of topic 1, node device 2 is responsible for processing messages of process 2. The device determines the target theme to which the information to be transmitted belongs, and the information to be transmitted is required to be sent to a target receiving end for processing the target theme. In this regard, after determining the plurality of target partitions, the apparatus first obtains a time delay between a third receiving end and each fourth receiving end in the target partition, where the time delay may be defined as a second time delay, the time delay between the second receiving end and the apparatus is defined as the second time delay, the third receiving end is a node device in the target partition that processes information of the target subject, and the fourth receiving end is a node device in the target partition except the third receiving end. The node equipment between the device and the target partition has a first time delay, and the device calculates the total time delay corresponding to each fourth receiving end, namely the total time delay is the sum of the first time delay between the fourth receiving end and the device and the second time delay between the third receiving end and the fourth receiving end. The device determines the minimum time delay in all total time delays, the fourth receiving end corresponding to the minimum time delay is determined to be the target receiving end, the device transmits the information to be transmitted to the target receiving end, and the target receiving end transmits the information to be transmitted to the third receiving end.
In this embodiment, the device acquires the network segment range of each cluster partition in the cluster, determines the second distance between the transmitting end and each cluster partition according to the first network segment and the lower limit network segment value of each network segment range, and determines the target partition in each cluster partition through the second distance, thereby determining each node device of the target partition as the first receiving end, that is, screening out the node devices with a relatively close distance to the transmitting end from a plurality of node devices as the first receiving end, reducing the data processing capacity of the device, and saving the computing resources of the device.
Referring to fig. 4, fig. 4 is a third embodiment of the data transmission method according to the present application, based on the first or second embodiment, step S201 includes:
step S401, detecting whether to store a second fixed transmission link associated with the transmitting end;
step S402, when the second fixed transmission link associated with the transmitting end is not stored, the first network parameter of the transmitting end is obtained according to the information to be transmitted.
In this embodiment, if the device receives the information sent by the sender for the first time, the device does not store the fixed sender link of the sender, so the device needs to fix the link for the sender, so that the device sends the message of the sender to the fixed receiver based on the fixed link.
In this regard, after receiving the information to be transmitted, the device detects whether to store a fixed transmission link associated with the transmitting end, where the fixed transmission link is defined as a second fixed transmission link. The device has an identification of the terminal that received the message recorded therein, for example. After receiving the information to be transmitted sent by the sending end, the device acquires the identification of the sending end based on the information to be transmitted and detects whether the identification is recorded or not. If the identification is not recorded, it can be determined that the transmitting end transmits information to the device for the first time, that is, the device does not store the second fixed transmission link associated with the transmitting end, and the device acquires the first network parameter of the transmitting end according to the information to be transmitted, that is, the device configures the fixed transmission link for the transmitting end.
In this embodiment, the device detects whether a second fixed transmission link associated with the transmitting end is stored, and if the second fixed transmission link is not stored, obtains a first network parameter of the transmitting end based on information to be transmitted, so as to configure the fixed transmission link for the transmitting end.
Referring to fig. 5, fig. 5 is a diagram illustrating a fourth embodiment of a data transmission method according to the present application, and after step S401, further includes:
in step S501, when a second fixed transmission link associated with the transmitting end is stored, information to be transmitted is transmitted to a receiving end corresponding to the second fixed transmission link.
In this embodiment, when detecting that the identifier of the transmitting end is recorded, the device determines that the transmitting end does not transmit information to the device for the first time, that is, the transmitting end is associated with a second fixed transmitting link, and the device transmits information to be transmitted to a receiving end corresponding to the second fixed transmitting link.
Further, the node devices in the cluster partition may have unstable networks, which may cause delay increase of data transmission, and even if the information sending link of the sending end is fixed, the device needs to determine whether the receiving end corresponding to the fixed sending link has the situation of delay increase caused by unstable networks.
In this regard, the apparatus determines a third receiving end corresponding to the second fixed transmission link. In view of the above occurrence of the third receiving end, the third receiving end occurring in this embodiment may also be defined as a fifth receiving end. The device acquires the historical record information of the network quality of the third receiving end, and predicts the predicted network quality parameter of the third receiving end in the current time period based on the historical record information. The device acquires the actual network quality parameter of the third receiving end in the current time period, and when the difference between the predicted network quality parameter and the actual network quality parameter is smaller than the preset difference and the predicted network quality parameter is smaller than the preset threshold, the time delay of the third receiving end can be determined not to be increased, and the device sends information to be transmitted to the third receiving end.
In an example, the history information records network quality parameters of the third receiving end in different time periods of each day, and if the network quality parameters are higher than a preset threshold, the delay of the third receiving end is not greatly affected. The device can train a prediction model in advance based on a plurality of pieces of history information, and output the current latest history information to the prediction model, so that the predicted network quality parameter of the third receiving end in the current time period can be obtained.
The difference between the predicted network quality parameter and the actual network quality parameter is smaller than a preset difference, which can represent that the network quality parameter of the third receiving end changes according to rules, so that when the predicted network quality parameter is smaller than a preset threshold, the time delay of the third receiving end can be determined not to be increased. If the difference between the predicted network quality parameter and the actual network quality parameter is greater than or equal to the preset difference, it may be determined that the network quality of the third receiving end does not fluctuate according to the previous rule, where the probability of network fluctuation of the third receiving end is greater, that is, the delay of the third receiving end is greatly affected, and the device acquires the first network parameter of the transmitting end based on the information to be transmitted, that is, the device reconfigures the fixed transmitting link for the transmitting end.
In this embodiment, the device detects whether to store the second fixed transmission link associated with the transmitting end, and if not, obtains the first network parameter of the transmitting end based on the information to be transmitted, that is, configures the fixed transmission link for the transmitting end.
In an embodiment, the device sends a plurality of test information to each second receiving end, so that the device can receive response information fed back by the second receiving ends based on each test information, and therefore, the device can calculate a plurality of target time delays of each second receiving end, and the device determines stability of the second receiving ends based on the respective target time delays of the second receiving ends, wherein the stability is used for indicating time delay fluctuation of the first receiving ends. The device determines a target receiving end in each second receiving end based on the stability and the target time delay, wherein the target time delay of the target receiving end is smaller than the preset time delay, and the stability of the target receiving end is smaller than the preset fluctuation value.
