LOW-LEVEL CONNECTIVITY ADMISSION CONTROL FOR NETWORKED CONSUMER STORAGE DEVICES

摘要

The present invention relates to a device and a method of accessing a storage of a storage device by reading or writing data to said storage device, wherein said accessing is controlled by an external data controller via a low level in a software stack of said device, and wherein said storage device is accessed without hampering the operation of functionalities at a higher level of said software stack of said device, said device comprises an intermediate storage, and the method comprises the steps of storing commands related to said accessing of data in said intermediate storage as a command queue, executing said commands in said command queue when allowed by a command queue scheduler, said scheduler scheduling in dependence of at least one of the functionalities at said higher level of said software stack. Thereby full control is obtained on storage medium requests by the scheduler.
