AI Technical Summary
Technical Problem
The existing health check method cannot accurately judge the health status of the RS device when the load balancing device does not receive the ICMP Destination Unreachable error message, and there is a possibility of misjudgment.
Method used
By establishing a TCP connection between the load balancing device and the RS device, and carrying the detection request message of the new TCP option, the UDP service port availability detection is carried out to determine the health status of the RS device.
Benefits of technology
It improves the accuracy of load balancing equipment's UDP service health status of RS equipment, reduces misjudgment of UDP port service availability, and enhances the reliability of load balancing systems.

Abstract
The invention provides a health check method, device and equipment, and relates to the technical field of cloud computing, firstly, under the condition that load balancing equipment does not receive an ICMP unreachable message of RS equipment to be checked for the first time, the load balancing equipment sends a detection request message carrying a TCP option to the RS equipment to be checked through TCP connection; and then the load balancing device receives a response request message returned by the to-be-checked RS device, and judges the health state of the to-be-checked RS device based on the response request message. The health check method is a check method of UDP service based on reliable connection, reliable TCP connection is newly established between load balancing equipment and RS equipment, a new TCP option is added, accurate detection of the load balancing equipment on the running condition of the UDP service on the RS equipment and the sending condition of ICMP unreachable messages is completed through a TCP interaction message carrying the new TCP option, and the reliability of the UDP service is improved. The accuracy of detecting the UDP service health condition of the RS equipment by the load balancing equipment is improved.
