Background
An important task of the load balancing server is to automatically detect software and hardware failures of the server by using a link load balancing health check technology, and if the server is not detected and the failed server is found, the client may send data request information to the failed server (for example, the server which has been stopped). For a server that has failed, the network administrator must manually replace or remove the failure of the server before the server can be reused by the client.
The link load balancing health check technology is to send a probe message to a server or some network nodes in a network by using some network protocols to determine whether the server or the network nodes are working normally. The link load balancing health check technology detects whether a server or a network node is in fault according to the characteristics of a used network protocol, link load balancing health detection can be carried out on the server or the network node based on different network protocols according to different requirements of users so as to determine whether the server or the network node is in fault, and the network protocol for detecting whether the server or the network node is in fault can select a TCP (transmission control protocol), an ARP (two-layer protocol), an ICMP/ICMPv6 (three-layer protocol), a TCP/UDP (four-layer protocol), an HTTP (hyper text transport protocol), an HTTPS (hypertext transfer protocol), an FTP (file transfer protocol) and the like. For example, the TCP protocol is a reliable transmission protocol, data transmission can be performed only after three handshakes are performed, link load balancing health check is performed on a server or a network node by using the characteristic, and if the three handshakes are successful, the server works normally.
However, sometimes the server may not have a fault, but due to a software bug, a network oscillation, a peak of network utilization, and the like, the application system running on the server may not work normally (for example, although the Web application may run normally, a page returned by the Web application is wrong content), and at this time, the load balancing server may confirm that the server has a fault, thereby causing a misjudgment on the server state.
Therefore, those skilled in the art need to develop a reliable network link load detection method to accurately determine the operating status of network nodes such as a server.

the specific calculation formula of the link tolerance is as follows:
wherein y is the link tolerance; m is the first piece of data in the database in the latest time period; n is the last data in the latest time period in the database; x is the number ofiIs the link bandwidth utilization; a is a variable coefficient used to adjust the percentage of the link tolerance.
2. The method of claim 1, wherein prior to the step of marking the final operating status of the local link according to link bandwidth utilization and link tolerance, the method further comprises:
and presetting the link tolerance according to the requirement.
3. The link intelligent detection method according to claim 1, further comprising:
marking the final operating state of the local link as available when the operating state indicates that the local link is available.
4. The method according to claim 3, wherein the step of detecting the working status of the local link using the existing network protocol specifically includes: the working state of the local link is detected according to a preset period by utilizing the existing network protocol.
5. The method of claim 4, wherein when the operating status indicates that the local link is available, the method further comprises:
calculating a plurality of said link bandwidth utilization rates for said local link according to said predetermined period; and
storing the link bandwidth utilization within a recent predetermined time period to a database.
6. The method of claim 5, wherein prior to the step of marking the final operating status of the local link according to link bandwidth utilization and link tolerance, the method further comprises:
calculating the link tolerance using the link bandwidth utilization for the most recent time period in the database.
7. A storage medium having stored thereon a computer program for performing the steps of the method of any one of claims 1 to 6 when executed by a processor.
8. A computer device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, the processor implementing the steps of the method of any one of claims 1 to 6 when executing the computer program.
