High-concurrency down-cut flow control method and device, equipment and storage medium

The invention relates to a high-concurrency down-cut flow control method and device, equipment and a storage medium. The method comprises the following steps: monitoring real-time concurrent request traffic initiated for a target service; the target service is a service under a bank system; and under the condition that the real-time concurrent request flow is greater than a concurrent upper limit corresponding to the target service, determining a flow cutting switch corresponding to the target service and a control parameter corresponding to the flow cutting switch, and controlling the target service based on the flow cutting switch and the control parameter. Partial request traffic in the real-time concurrent request traffic is switched to other services under the bank system; wherein at least part of services in the bank system correspond to flow switching switches, and different flow switching switches are respectively configured with respective control parameters. By adopting the method, the flow cutting
