Abstract

The present invention provides a read / write control system and method, which are applied to a block device. The method comprises: providing block device configuration policies, associating a block device configuration called by each block device configuration policy with a preset flow value, and storing an association relationship in a preset table; under the condition of enabling a preset first operating mode to be started, monitoring a block device read / write request initiated by an application, and when a current flow value of the block device read / write request, which is acquired within a unit time, is greater than a preset threshold, matching the corresponding block configuration policy in the preset table according to the current flow quantity value; and and performing scheduling on the configuration of the block device according to the matched block configuration policy. By providing scheduling control on read / write flow, a frequency degree of disk access of a read / write-operation-intensive scenario is smoothened, and user experience is improved.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a read-write control system and method. Background technique [0002] At present, all Android mobile devices support MTP and UMS mode copying, and use the USB cable to download files from the PC to the disk of the mobile device. During the download process, the mobile device has a large number of write operations to the disk. At this time, if the user clicks on the application, especially when the startup of these applications also needs to read data from the disk, abnormal freezes will occur at this time. This is because the application needs and downloads to compete for the bandwidth of the disk, resulting in a long waiting time for the IO of the system, and the application cannot obtain data, resulting in slow initialization and poor user experience. Especially if it is a low-end disk device, this poor user experience will be magnified. Contents of the invention [0003] ...
