Referring to fig. 1 and fig. 1a, fig. 1 is a schematic flowchart of a method for managing a link pool according to an embodiment of the present application, and fig. 1a is a schematic view of a scenario of the method for managing the link pool according to the embodiment of the present application. The link pool management method is applied to the server 10. The server 10 can perform communication connection with the client 20, the user sends a link access request through the client 20, so as to call a link in a link pool of the server 10, and the server 10 can return response information according to the request of the client 20; if the server 10 detects that a link in the current link pool is used, receiving a first link request for detecting activity, which is sent by the client 20, through the used link at preset intervals and responding to the first link request, which is sent by the client 20, so as to ensure that the used link is in a connection state; when the link utilization rate in the current link pool is detected, whether the detected link utilization rate is greater than a first preset value or not can be judged, if yes, the server 10 can call and run a preset expansion script, so that the expansion of the link pool is realized, the corresponding link quantity is increased, the quick and effective management of the link pool is effectively realized, and meanwhile, the continuous availability of the link is ensured. The steps of the link pool management method will be described in detail below from the perspective of the server 10.
As shown in fig. 1, in this embodiment, the method for managing a link pool may specifically include steps S101 to S103.
Step S101, if it is detected that a link in the current link pool is used, receiving and responding to a first link request for detecting activity, which is sent by a client and matched with the link, through the used link at preset intervals, so as to ensure that the used link is in a connection state.
In this embodiment, in order to prevent the used link from being recycled by the link pool due to being idle, the server and the client need to maintain the available connection state of the link by setting a corresponding active mechanism. That is, if the server detects that a link in the current link pool is used, at this time, the server may receive and respond to a first link request for detecting activity, which is sent by the client and matched with the first link request, at preset intervals, so as to ensure that the used link is in a connection state; at this time, according to a preset rule, after the link request finally used in the formal mode is sent, the client sends the first link request for detecting activity through the used link at preset intervals, and therefore the link is ensured to be in a used state.
Step S102, detecting the link utilization rate in the current link pool.
In this embodiment, the server can receive a link use request sent by the client to the link pool of the server, so as to call a corresponding link to implement information interaction with the client. Generally, the size of the link pool can be set, and the total number of links in the link pool and the number of used links called can be determined, so that the server can detect the link usage rate in the current link pool.
For example, when the total number of the links in the link pool can be 100, the server may detect the number of used links, and in order to ensure that the use of the links in the link pool is not tight, it may be ensured that at least 20% of the links are in an idle state, so that the current link usage rate needs to be detected.
As shown in FIG. 2, in one embodiment, the step S102 includes steps S201 to S202.
In step S201, a preset link detection thread is called to obtain the total number of links and the number of used links in the link pool.
In this embodiment, the server can call one of the existing threads as a preset link detection thread, so as to obtain the total number of links in the link pool according to the preset link detection thread and obtain the number of used links at the same time. For example, the connection state of each link in the link pool can be acquired at intervals through the link detection thread, so that the number of used connections and the total number of links in the link pool can be updated and determined in time.
In step S202, the ratio of the number of used links to the total number of links is determined as the link utilization rate.
Specifically, the server determines the ratio as the link utilization rate by calculating the ratio of the number of used links to the total number of links, so as to rapidly manage the link pool and ensure the connection of the used links.
Step S103, determining whether the detected link utilization rate is greater than a first preset value.
In this embodiment, the server further needs to determine whether the detected connection usage rate is greater than a first preset threshold. The first preset threshold value can be set according to the actual use requirement of the user.
And step S104, if the detected link utilization rate is greater than a first preset value, calling and running a preset expansion script so as to expand the capacity of the link pool and increase the corresponding link quantity.
In this embodiment, if the detected connection usage rate is greater than the first preset value, it indicates that the load of the link pool is excessive, and the server may call and run a preset expansion script in order to ensure that the used connection can be continuously used and avoid being withdrawn by the server. In this embodiment, the preset capacity expansion script can be set according to the user requirement, so that after the capacity expansion script is run, the capacity expansion of the link pool can be performed, that is, the capacity expansion of the link pool can be performed, so that the corresponding number of links is increased, the situation that the number of idle links in the link pool is too small is avoided, the use experience of a user is improved, the link pool is effectively managed quickly and effectively, and the continuous availability of the links is ensured.
As shown in FIG. 3, in one embodiment, the step S104 includes steps S301-S303.
Step S301, a preset expansion script is called to obtain a corresponding configuration file.
In this embodiment, the preset expansion script may include a configuration file, and the configuration file may record related expansion parameters, so that the server needs to call the corresponding configuration file to expand the link pool.
Step S302, determining the corresponding link quantity according to the capacity increasing parameters preset in the configuration file.
In this embodiment, the server can determine the corresponding number of links according to the capacity increase parameter in the acquired configuration file. For example, when the first preset value is 80%, the link pool may be expanded by 20%. Of course, the first preset value is not limited to 80%, may also be 70%, and more may be 90%, which is not limited in this embodiment.
Step S303, expanding the link pool to increase the determined number of links.
In this embodiment, the server may expand the volume of the link pool, so as to increase the number of links in the link pool, that is, alleviate the connection pressure of the link pool, and improve the user experience.
In a further embodiment, the method may further comprise the steps of:
step S105, if the detected link utilization rate is less than or equal to a first preset value, determining whether the detected link utilization rate is less than a second preset value, wherein the first preset value is greater than the second preset value.
In this embodiment, if the detected link utilization rate is less than or equal to the first preset value, it may be determined again whether the detected link utilization rate is less than the second preset value, so as to perform the distinguishing process. Wherein the first predetermined value is greater than said second predetermined value.
And step S106, if the detected link utilization rate is smaller than a second preset value, calling and running a preset capacity reduction script so as to reduce the capacity of the link pool and reduce the corresponding link quantity.
In this embodiment, if the detected link utilization rate is less than the second preset value, it indicates that the number of idle links in the link pool is sufficient, and at this time, the used link may be closed by the server because the client does not initiate a connection state in time, especially, the firewall of the server may also be closed by the firewall because the idle time of the link is long, and at this time, the server may call and run the preset abbreviated script. In this embodiment, the preset capacity reduction script can be set according to the user requirement, so the capacity reduction script is run, namely, can be right the link pool capacity reduction, thereby reducing the corresponding link quantity, avoiding excessive idle links in the link pool, improving the user experience, effectively realizing the quick and effective management of the link pool, and simultaneously ensuring the continuous availability of the link.
As shown in FIG. 4, in one embodiment, the step S106 includes steps S401 to S403.
Step S401, a preset capacity reduction script is called to obtain a corresponding configuration file.
In this embodiment, the preset capacity reduction script may include a corresponding configuration file, and the configuration file may record related capacity reduction parameters, so that the server needs to call the corresponding configuration file to implement capacity reduction on the link pool.
Step S402, determining the corresponding link quantity according to the preset capacity shrinkage parameters in the configuration file.
In this embodiment, the server can determine the corresponding number of links according to the capacity reduction parameters in the acquired configuration file. For example, when the second preset value is 20%, the link pool may be scaled by 50%. Of course, the second preset value is not limited to 20%, may also be 10%, and more may be 30%, which is not limited in this embodiment.
Step S403, performing a reduction on the link pool to reduce the determined number of links.
In this embodiment, the server may reduce the volume of the link pool, so as to reduce the number of links in the link pool, that is, improve the user experience.
In still further embodiments, the method may further comprise the steps of:
step S107, if the detected link utilization rate is greater than or equal to a second preset value and the waiting time after the used link is detected to respond to the previous link request is greater than the preset interval time, monitoring whether the waiting time reaches preset timeout time; the preset interval time is less than the preset timeout time, and the previous link request comprises a first link request.
In this embodiment, if the detected link utilization rate is greater than or equal to the second preset value, it is known that the link utilization rate is between the first preset value and the second preset value, so that theoretically, the server can receive and respond to the first link request, sent by the client at preset intervals, for detecting the used link, so that the server can determine that the used link is in a used state, thereby avoiding the recovery of the used link pool, and ensuring that the client can also connect to the server through the used link. The preset interval time may be 1s or 2s, but the preset interval time is not limited herein in this embodiment. The preset interval time is less than the preset timeout time, which may be 4s or 5s, and is not limited in this embodiment. If the waiting time after the used link is detected to respond to the previous link request is longer than the preset interval time, the previous link request can represent a normal link request initiated from the client to the server under a general condition or can be a first link request for detecting activity, at this time, whether the waiting time reaches preset timeout time needs to be monitored, if so, a warning is given, and if not, reverse activity detection can be initiated.
Step S108, if the waiting time is monitored not to reach the preset timeout, a second link request for reverse activity detection is initiated to the client through the used link, so that the client is controlled to respond to the first link request for generating a response.
In this embodiment, if the waiting time after the server detects that the used link responds to the previous link request is longer than the preset interval time, it indicates that the link request for detecting activity does not directly pass through the used link of the server at this time, so to avoid closing the used link by the server, it is necessary to monitor whether the waiting time reaches the preset timeout time, and if the preset timeout time is not reached, it indicates that the used link is in an available and unaffected state. That is, if it is monitored that the waiting time does not reach the preset timeout, the server can send a second link request for reverse activity detection to the client through the used link, so that the client is controlled to generate and send a corresponding first link request after receiving the second link request, thereby realizing bidirectional activity detection between the server and the client, and improving the utilization efficiency of the link of the embodiment.
In still further embodiments, the method may further comprise the steps of:
step S109, if the waiting time reaches the preset overtime, generating early warning information and sending the early warning information to the client so that the user can select whether to stop the used link.
In this embodiment, if the server monitors that the waiting time reaches the preset timeout time, the server may generate the warning information and send the warning information to the client, so that the user can select whether to deactivate the used link, thereby ensuring the continuous availability of the link, and improving the utilization efficiency of the link and the user experience.
In summary, the embodiment of the present invention can realize fast and effective management of the link pool, and can ensure continuous availability of the link, and improve utilization efficiency of the link and user experience.

Wherein the first predetermined value is greater than said second predetermined value.
And a capacity reduction unit 106, configured to, if the detected link utilization rate is smaller than a second preset value, call and run a preset capacity reduction script, so as to reduce the capacity of the link pool and reduce the number of corresponding links.
In this embodiment, if the detected link utilization rate is less than the second preset value, it indicates that the number of idle links in the link pool is sufficient, and at this time, the used link may be closed by the server because the client does not initiate a connection state in time, especially, the firewall of the server may also be closed by the firewall because the idle time of the link is long, and at this time, the server may call and run the preset abbreviated script. In this embodiment, the preset capacity reduction script can be set according to the user requirement, so the capacity reduction script is run, namely, can be right the link pool capacity reduction, thereby reducing the corresponding link quantity, avoiding excessive idle links in the link pool, improving the user experience, effectively realizing the quick and effective management of the link pool, and simultaneously ensuring the continuous availability of the link.

In this embodiment, if the detected link utilization rate is greater than or equal to the second preset value, it is known that the link utilization rate is between the first preset value and the second preset value, so that theoretically, the server can receive and respond to the first link request, sent by the client at preset intervals, for detecting the used link, so that the server can determine that the used link is in a used state, thereby avoiding the recovery of the used link pool, and ensuring that the client can also connect to the server through the used link. The preset interval time may be 1s or 2s, but the preset interval time is not limited herein in this embodiment. The preset interval time is less than the preset timeout time, which may be 4s or 5s, and is not limited in this embodiment. If the waiting time after the used link is detected to respond to the previous link request is longer than the preset interval time, the previous link request can represent a normal link request initiated from the client to the server under a general condition or can be a first link request for detecting activity, at this time, whether the waiting time reaches preset timeout time needs to be monitored, if so, a warning is given, and if not, reverse activity detection can be initiated.
