The application relates to a data access request processing method and device, computer equipment, a computer readable storage medium and a computer program product. The method comprises the following steps: when a plurality of data access requests are received, selecting candidate data access requests meeting a matching condition from the plurality of data access requests; based on a bucket size of a concurrent leaky bucket corresponding to a current time period, controlling a target data access request in the candidate data access requests to enter the concurrent leaky bucket; the number of the target data access requests is not greater than the bucket size of the concurrent leaky bucket, and the bucket size is equal to a concurrent limit number; performing response processing on each target data access request in the concurrent leaky bucket, and performing blocking processing on the remaining data access requests in the candidate data access requests. By using the method, data access requests for hot files can be limited, and corresponding bandwidth resources can be reserved to process non-hot file access.

The application relates to the technical field of network flow control, and discloses a multi-link flow control method based on bucket multiplexing, which is applied to a flow control device, the flow control device comprises a first bucket space, a second bucket space and a plurality of interface groups for receiving traffic, comprises determining a logical link identifier based on traffic identification information for the traffic entering the flow control device, obtaining corresponding target bucket addressing information, and jointly executing flow control according to the interface groups to the corresponding buckets in the first bucket space and the second bucket space, and then splitting the target total flow control rate into a first flow control rate and a second flow control rate according to the traffic distribution information in the double-bucket space and respectively configuring the first flow control rate and the second flow control rate. The method realizes the expansion of the link flow control capability without increasing the number of physical buckets and improves the stability of the double-space joint flow control.

This application discloses a flow control method, apparatus, device, and medium for input / output requests, relating to the field of computer technology. The method includes: responding to an input / output request corresponding to a disk array, obtaining the request type of the input / output request, wherein the request type is an access request or a maintenance request, where an access request is used to enable an external device to perform data access operations on the disk array, and a maintenance request is used to enable internal maintenance operations on the disk array; if the request type is an access request, determining the request queue corresponding to the input / output request as a token bucket queue; or, if the request type is a maintenance request, determining the request queue corresponding to the input / output request as a leaky bucket queue; and adding the input / output request to the request queue corresponding to the input / output request. This application combines the token bucket and leaky bucket mechanisms, balancing the burstiness of access requests with the stability of maintenance requests.
