Fig. 2 is a flowchart of a method of adjusting data transmission delay according to an embodiment of the present application. As shown in fig. 2, the method comprises the steps of:

step S201, current network performance parameters of a data sending end and a data receiving end and network loads between the data sending end and the data receiving end are obtained, wherein the current network performance parameters are used for representing transmission performance between the data sending end and the data receiving end at the current moment, and the data sending end is used for transmitting target data to the data receiving end;

Specifically, the network performance parameters may include, but are not limited to, the following: bandwidth, delay, packet loss rate, throughput and network jitter, wherein bandwidth refers to the maximum speed of network transmission data, and is measured by the number of bits transmitted per second, and the higher the bandwidth, the faster the network transmission speed; delay refers to the time required by data from a transmitting end to a receiving end, measured in milliseconds, the lower the delay, the faster the network response speed; the packet loss rate refers to the proportion of data packets lost by the network when transmitting data, and the lower the packet loss rate is, the more reliable the network transmission is; throughput refers to the data quantity which can be transmitted by a network in unit time, and the higher the throughput is, the higher the network transmission efficiency is; network jitter refers to the instability of the network in transmitting data, measured by the variance of the time interval of the data packet reaching the receiving end, and the smaller the jitter, the more stable the network transmission. The network load refers to the load and pressure born by the network in the data transmission process, the size of the network load depends on factors such as data transmission quantity, network bandwidth, network topology structure, network equipment performance and the like, the size of the network load directly influences the speed and stability of data transmission, and especially the influence on data transmission with high real-time requirements is larger.

Step S202, according to the magnitude of the network load, the magnitude of an initial performance parameter threshold is adjusted to obtain a target performance parameter threshold, wherein the initial performance parameter threshold is a preset parameter used for determining whether delay exists in data transmission between the data sending end and the data receiving end;

Specifically, different target performance parameter thresholds are set according to different network load sizes, so that delay detection under the condition of different network load sizes can be met.

Step S203, determining that there is a delay in data transmission between the data sending end and the data receiving end and outputting a delay signal when the current network performance parameter is greater than the target performance parameter threshold, wherein the delay signal is used for representing that there is a delay in data transmission between the data sending end and the data receiving end;

Specifically, the target performance parameter threshold may be set in a network monitoring tool, for example: cacti. When the current network performance parameter exceeds the target performance parameter threshold, the system can send out an alarm, and an administrator can be notified through an email, a short message or other instant communication tools by configuring the real-time alarm system.

Step S204, obtaining the current adjustment parameter corresponding to the current network performance parameter, and adjusting the current network performance parameter by adopting the current adjustment parameter to reduce the data transmission delay between the data transmitting end and the data receiving end.

In particular, in the case where the current network performance parameter includes bandwidth, the delay of data transmission may be reduced by increasing the network bandwidth. In the case that the current network performance parameters include configuration parameters of the router and the switch, the configuration parameters of the router and the switch can be adjusted, so that the transmission time of the data packet in the network is reduced. The adjusted network bandwidth value and the configuration parameter value are the current adjustment parameters corresponding to the current network performance parameters.

Through the embodiment, a method for adjusting data transmission delay is provided, firstly, current network performance parameters of a data sending end and a data receiving end and network load between the data sending end and the data receiving end are obtained; according to the magnitude of the network load, the magnitude of the initial performance parameter threshold is adjusted to obtain a target performance parameter threshold; then, under the condition that the current network performance parameter is larger than the target performance parameter threshold, determining that delay exists in data transmission between the data sending end and the data receiving end, and outputting a delay signal; and finally, acquiring a current adjustment parameter corresponding to the current network performance parameter, and adjusting the current network performance parameter by adopting the current adjustment parameter to reduce the data transmission delay between the data transmitting end and the data receiving end. The threshold is dynamically adjusted according to the network load, instead of using a fixed threshold to detect excessive delay, the accuracy of detecting the data transmission delay can be improved in the process of judging according to the current network performance parameter and the threshold, and then the current network performance parameter is adjusted by adopting the current adjustment parameter, so that the lost connection is reduced due to excessive delay recovery, and the problem of connection loss caused by the data transmission delay is solved.

In a specific implementation process, the step S202 may be implemented by the following steps: step S2021, when the network load is less than the load threshold, increasing the initial performance parameter threshold to a first target value to obtain the target performance parameter threshold; step S2022, when the network load is equal to or greater than the load threshold, of decreasing the initial performance parameter threshold to a second target value, to obtain the target performance parameter threshold, wherein the second target value is smaller than the first target value. The method can further meet the accuracy of delay detection under the condition of different network load sizes.

In particular, in the case that the network load is smaller than the load threshold, it is indicated that the network load is lighter, and the adaptive threshold may be automatically increased, so that the delay alarm signal is not triggered due to normal delay fluctuation, that is, false positives may be reduced. The network load is larger than or equal to the load threshold, so that the network load is relatively heavy, the self-adaptive threshold can be automatically reduced, and potential performance problems can be timely found even under the condition of relatively small delay, namely false negatives can be reduced.

In order to further timely and efficiently obtain the current adjustment parameters corresponding to the current network performance parameters, the step S204 of the present application may be implemented by the following steps: step S2041, inputting the current network performance parameter into a neural network model to obtain the current adjustment parameter, where the neural network model is trained by machine learning using a plurality of sets of historical data, and each set of data in the plurality of sets of historical data includes: the system comprises a historical network performance parameter and a historical adjustment parameter, wherein the historical network performance parameter is used for representing transmission performance between the data sending end and the data receiving end at a historical moment, and the historical adjustment parameter is used for adjusting the historical network performance parameter so as to reduce data transmission delay between the data sending end and the data receiving end.

Specifically, in practical application, the training process of the neural network model is as follows: first, a large amount of historical data is collected about network performance, such as: the device reports frequency data of the data, the data amount in the network, etc. And then carrying out denoising and outlier preprocessing on the data, extracting key characteristic values as data input of an initial model, continuously learning and adapting to network change behaviors by the system, and improving prediction and judgment to obtain the neural network model. Inputting a large amount of data of the current network performance parameters obtained by real-time monitoring into the neural network model, and obtaining the current adjustment parameters corresponding to the current network performance parameters.

The data transmitting end and the data receiving end have a plurality of transmission paths therebetween, and the step S203 may be implemented in other manners, for example: in step S205, the target data is transmitted by using a plurality of transmission paths according to a predetermined communication protocol, where the predetermined communication protocol is an equal cost multi-path routing protocol or a link aggregation group protocol. The method adopts a preset communication protocol to disperse the flow to different paths, so that congestion can be avoided, and the time delay is further reduced.

In particular, the Equal Cost Multi-Path (ECMP routing protocol) is a routing algorithm for selecting multiple Equal paths in a network. In conventional routing protocols, when a router encounters multiple equivalent paths, only one of the paths is typically selected for data transmission. The ECMP protocol allows the router to simultaneously utilize a plurality of equivalent paths for data transmission when encountering the paths, thereby improving the bandwidth utilization rate and the load balancing capability of the network. The working principle of the ECMP protocol is that a plurality of equivalent paths are stored for the same destination network in a routing table of a router, and one path is selected for forwarding according to a certain load balancing algorithm when a data packet arrives. The link aggregation group protocol (Link Aggregation Group, abbreviated LAG routing protocol) is a protocol for combining multiple physical links into a single logical link. This technique may provide higher bandwidth, redundancy, and load balancing, thereby improving the performance and reliability of the network. LAG routing protocols allow multiple physical links to be logically combined into one larger link, thereby increasing overall bandwidth and reliability. When one of the physical links fails, the data can be automatically switched to other normal links, thereby ensuring the connectivity of the network. In the LAG routing protocol, data transmission between multiple physical links is load balanced by a specific algorithm. According to different conditions, such as a source IP address, a destination IP address, a source port, a destination port and the like, data are distributed to different physical links so as to realize the maximum utilization of bandwidth and the balanced distribution of network traffic. Common LAG routing protocols include LACP (Link Aggregation Control Protocol), PAGP (Port Aggregation Protocol) and static link aggregation.

In some embodiments, the following steps may be implemented after the step S203: step S206, determining the transmission priority of the target data according to the current network performance parameter, wherein the transmission priority comprises a first priority, a second priority and a third priority; step S207, transmitting the target data in sequence according to the third priority, the second priority and the first priority. The method can ensure that important data is processed preferentially in the transmission process by determining the transmission priority, and further improve the efficiency and the speed of data transmission.

Specifically, the method can further reduce the risk of data loss, increase the transmission priority of important data, reduce the risk of data loss, ensure that the important data can be transmitted and received in time, optimize the network transmission flow, improve the network quality and reduce the network congestion and delay.

The current network performance parameter at least includes a quality parameter, where the quality parameter is used to evaluate the network performance of the data transmission between the data transmitting end and the data receiving end, and the step S206 may be implemented by: step S2061 of determining whether the quality parameter is smaller than a first parameter threshold, and determining the transmission priority of the target data as the first priority if the quality parameter is smaller than the first parameter threshold; step S2062 of determining whether the quality parameter is smaller than a second parameter threshold value, which is larger than the first parameter threshold value, when the quality parameter is equal to or larger than the first parameter threshold value; step S2063 of determining the transmission priority of the target data as the second priority when the quality parameter is equal to or greater than the first parameter threshold and is less than the second parameter threshold; in step S2064, when the quality parameter is equal to or greater than the second parameter threshold, the transmission priority of the target data is determined to be the third priority. According to the method, the transmission priority of the target data is determined according to the size of the quality parameter, so that the important data can be further ensured to be transmitted timely and reliably.

In particular, the quality parameter may be quality of experience or quality of service, where quality of experience (Quality of Experience, abbreviated as QoE) refers to the overall quality of experience of a user when using a certain service or product. It is not only concerned with technical indicators but also the user's perception and satisfaction with the service. For example: reliability of service, response speed, interface friendliness, audiovisual quality, interactive experience, etc. QoE is a subjective concept because it depends on the user's personal experience and desire. For example, for video streaming services, qoE may be affected by factors such as video quality, buffering delay, smoothness of play, etc. Quality of service (Quality of Service, abbreviated QoS) refers to the quality of service that the system provides for a particular data flow in network communications. The method comprises the technical indexes of reliability, bandwidth, time delay, jitter and the like of the network. QoS ensures stability and reliability of data transmission through network devices and protocols, thereby ensuring that a specific quality of service meets the needs of users. When the quality parameter is smaller than the first parameter threshold, indicating that the data priority is general and the first priority is the first priority, and only allocating general resources is needed; when the quality parameter is greater than or equal to the first parameter threshold and less than the second parameter threshold, indicating that the data priority is medium, namely the second priority, and allocating medium resources; and when the quality parameter is greater than or equal to the second parameter threshold, indicating that the data priority is higher, preferentially allocating higher resources, and preferentially transmitting.

The data receiving end includes a buffer area, where the buffer area is used to store data, and in one embodiment, the method may further be implemented by the following steps: step S2081, adjusting the storage amount of the buffer to a third target value when the transmission priority of the target data is the first priority; step S2082, when the transmission priority of the target data is the second priority, adjusting the storage amount of the buffer to a fourth target value, wherein the fourth target value is greater than the third target value; in step S2083, when the transmission priority of the target data is the third priority, the storage amount of the buffer is adjusted to a fifth target value, where the fifth target value is greater than the fourth target value. According to the method, the size of the storage space of the buffer area can be adjusted according to the data priority of the target data, so that the key data delay in the buffer area is further reduced.

In particular, in a network environment, for critical traffic (e.g., real-time communication or high priority data transmission), the system may allocate more buffer resources to ensure that the transmission of such data is as smooth as possible and to reduce latency. Further, the sending rate of the data may also be adjusted when signs of congestion are detected to avoid congestion and packet loss.

In yet another embodiment, the step S203 further includes: step S2084, determining whether the data stored in the buffer area is the same as the target data; in step S2085, when the data stored in the buffer is the same as the target data, the reception of the target data transmitted from the data transmitting terminal is stopped. According to the method, the data is directly acquired from the buffer zone of the data receiving end, so that the delay of acquiring the data from the remote data transmitting end can be further avoided.

In particular, caching is a method of storing temporary copy data in order to quickly provide target data in subsequent requests. Caches are typically used to store frequently accessed data, such as web pages, files, database query results, and the like. When data is requested, the system first checks if there is a copy of the data in the cache. If so, the data is directly provided from the cache, and the delay of acquiring the data from the original position of a remote server and the like is avoided.

In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the method for adjusting data transmission delay of the present application will be described in detail below with reference to specific embodiments.

The embodiment relates to a specific data transmission delay adjustment method, as shown in fig. 3, including the following steps:

step S1: continuously monitoring delay indexes of the network to perform delay monitoring;

step S2: determining when the connection experiences excessive delay or detecting that the connection is lost due to a network problem;

Step S3: according to the detected problem, adjusting a delay parameter to mitigate excessive delay and restore connection;

step S4: communicating with the network device or endpoint involved, exchanging feedback information;

Step S5: in case of connection timeout or packet loss, starting retransmission or reestablishing connection using optimized delay settings;

Step S6: priority ordering is carried out on key traffic or broadband resources are effectively allocated by combining quality parameters, so that timely and reliable transmission of important data is ensured;

Step S7: cooperating with network elements such as routers, switches, load balancers, firewalls, etc., to effect connection restoration.
