[0039] Embodiment 1

[0040] Figure 1 The present invention provides a processing flow of a network adaptive switching method provided in an embodiment of the present invention. The method is applied to a server including at least two network protocols. The method includes at least the following processing steps:

[0041] Step S1, obtaining network environment attribute information of the network;

[0042] Step S2: Based on the network environment attribute information, the network environment of the network is detected according to a preset network status detection rule to obtain network environment status information of the network;

[0043] Step S3: Based on the network environment status information, the network protocol is switched according to a preset network adaptive switching rule.

[0044] The network protocol includes a private network protocol and a public network protocol; specifically, the private network protocol may be the HTTP / 2.0 protocol, and the public network protocol may be the HTTP / 1.1 protocol.

[0045] In actual application scenarios, the HTTP / 2.0 protocol is based on the TCP protocol, which multiplexes data streams on a single connection to improve data throughput and performance; however, the use of the HTTP / 2.0 protocol is greatly affected by network quality. When the network quality is poor, the retransmission of the TCP layer will cause the blocking of all multiplexed data streams on the link. The HTTP / 1.1 protocol uses a single-channel method. Although it will reduce throughput and performance, the retransmission of a single TCP link will not affect other links. Based on this, this embodiment proposes a network adaptive switching method to improve the stability and efficiency of network transmission and reduce the risk of HTTP / 2.0 blocking when the network quality is poor.

[0046] In one embodiment, obtaining network environment attribute information of the network includes: responding to a data stream transfer request, obtaining the number of data stream timeout retransmissions, the data stream transfer time of the data stream, and the data stream traffic of the data stream; responding to a TCP detection signal, obtaining the TCP detection time.

[0047] Specifically, by configuring detection tasks and detection channels on the server, the number of data flow timeout retransmissions of the data flow is obtained; by configuring quality detection and judgment on the server, the data flow transfer time and data flow volume of the data flow are obtained.

[0048] In one embodiment, based on the network environment attribute information, the network environment of the network is detected according to preset network status detection rules, and the network environment status information of the network is obtained, including: when at most two network environment attribute information among the number of data stream timeout retransmissions, the data stream transfer time, the data stream traffic and the TCP detection time do not meet the preset conditions, the network environment status information is determined to be abnormal.

[0049] In one of the embodiments, based on the network environment attribute information, the network environment of the network is detected according to preset network status detection rules, and the network environment status information of the network is obtained, including: when at least three of the network environment attribute information of the data stream timeout retransmission times, the data stream transfer time, the data stream traffic and the TCP detection time do not meet the preset conditions, the network environment status information is determined to be severely abnormal.

[0050] Specifically, the network environment is detected in multiple ways and from multiple angles to improve the accuracy of the network environment detection results; the network environment status information is detected by setting preset conditions, and the network environment status information is determined in time without manual supervision. When it is detected that the network environment status information does not meet the preset conditions, the network environment status information is automatically pushed, which simplifies the complexity of operation and maintenance and improves the flexibility and scalability of the system.

[0051] In one embodiment, the method further includes: if the number of data stream timeout retransmission times is greater than a preset timeout retransmission threshold, then it is determined that the data stream timeout retransmission times does not meet the preset conditions; if the data stream transfer time is greater than the preset transfer time threshold, then it is determined that the data stream transfer time does not meet the preset conditions; if the data stream traffic is greater than the preset traffic threshold, then it is determined that the data stream traffic does not meet the preset conditions; if the TCP detection time is greater than the preset detection time threshold, then it is determined that the TCP detection time does not meet the preset conditions.

[0052] Specifically, the status of the network environment is obtained based on preset condition judgment rules, which simplifies the complexity of operation and maintenance and improves the flexibility and scalability of the server; at the same time, by setting up a variety of monitoring methods, the accuracy of network environment status detection is ensured, thereby ensuring the quality of network transmission.

[0053] In one of the embodiments, the method further includes: obtaining the TCP detection time consumption for a preset number of times; and determining the detection time consumption threshold based on the TCP detection time consumption for the preset number of times.

[0054] It should be understood that this application does not limit the size of the preset number of times, and those skilled in the art can make adaptive adjustments according to actual application scenarios. Preferably, determine that the current acquisition of TCP detection time is the nth time; obtain the total TCP detection time from the 1st to the n-1th TCP detection time, and the total number of TCP detection time; determine the quotient of the total TCP detection time and the total number of acquisitions as the detection time threshold.

[0055] In one embodiment, based on the network environment status information and in accordance with preset network adaptive switching rules, switching the network protocol includes: when the network environment status information is abnormal, switching a preset proportion of data streams from a private network protocol to a public network protocol until the network environment status information is normal; the network protocol includes a private network protocol and a public network protocol.

[0056] In one embodiment, based on the network environment status information and in accordance with preset network adaptive switching rules, switching the network protocol includes: when the network environment status information is severely abnormal, switching the data flow from the private network protocol to the public network protocol until the network environment status information is normal.

[0057] Specifically, through the preset network adaptive switching rules, when the bandwidth is saturated or the network environment has serious quality problems, the private network protocol will be switched to the public network protocol to optimize bandwidth utilization and ensure network transmission quality.

[0058] In one embodiment, when the network environment status information is abnormal, a preset proportion of data flows is switched from a private network protocol to a public network protocol until the network environment status information is normal, including: if the data flow rate is greater than a preset flow threshold, the preset proportion is determined based on the data flow rate and the flow threshold, and the preset proportion of data flows is switched from the private network protocol to the public network protocol until the network environment status information is normal; otherwise, the time point when the network environment status is determined to be abnormal is used as the time node, and all data flows after the time node are switched from the private network protocol to the public network protocol until the network environment status information is normal.

[0059] In one embodiment, the method further includes: determining the preset ratio; determining the preset ratio includes: determining the flow ratio of data flow exceeding the preset flow threshold, and determining the flow ratio as the preset ratio. That is, if the data flow exceeds the preset flow threshold by 10%, 10% of the data flow is switched from the private network protocol to the public network protocol until the data flow is no greater than the preset flow threshold.

[0060] In one embodiment, after a preset proportion of data flow is switched from a private network protocol to a public network protocol, the method further comprises: real-time monitoring of the flow ratio of data flow that exceeds a preset flow threshold; adjusting the preset ratio in real time according to the flow ratio, and switching the preset proportion of data flow from the private network protocol to the public network protocol.

[0061] Specifically, if the data flow rate is greater than the preset flow threshold, the data flow whose flow rate exceeds the preset flow threshold is switched from the private network protocol to the public network protocol; if the data flow rate is not greater than the preset flow threshold, the number of data flow timeout retransmissions is greater than the preset timeout retransmission threshold, or the data flow transfer time is greater than the preset transfer time threshold, or the TCP detection time is greater than the preset detection time threshold, then the time when the network status is determined to be abnormal is used as the time node, and all data flows after this time node are switched from the private network protocol to the public network protocol. That is, assuming that the time point when the network status is determined to be abnormal is 21:30, all new incoming data flows after 21:30 will go through the public network protocol.
