Processing user's requested part of flow control based on user specifically includes following steps：
A) first check whether to enable the setting of user QOS quotas；
B) assuming that it is Q to be provided with QOS quotas, TOKEN is arranged to T, i.e., just increases a token in bucket every 1/Q seconds,
The maximum quantity for allowing token in bucket is Q+T；
C) it is R to assume active user's I/O request, and each request of user is owned by a token；
D) if existing token number Q (≤Q+T) more than the I/O request R of user, illustrates user's request in QOS quotas in bucket
Interior, each IO obtains token, and R token is deleted from bucket, and request is added into request processing queue and continues with；
E) if for existing token number Q (≤Q+T) less than the I/O request R of user, this has R-Q` I/O request to obtain in bucket
Less than token, only Q` I/O request can be added into request processing queue and be handled, and delete Q` token in bucket, in addition

The thought of board bucket is specifically designed and realized to complete：
A) first check whether to enable the setting of user QOS quotas；
B) assuming that it is Q to be provided with QOS quotas, TOKEN is arranged to T, i.e., just increases a token in bucket every 1/Q seconds,
The maximum quantity for allowing token in bucket is Q+T；
C) it is R to assume active user's I/O request, and each request of user is owned by a token；
D) if existing token number Q` (≤Q+T) more than the I/O request R of user, illustrates that user's request is matched somebody with somebody in QOS in bucket
In volume, each IO obtains token, and R token is deleted from bucket, and request is added into request processing queue and continues with；
E) if for existing token number Q` (≤Q+T) less than the I/O request R of user, this has R-Q` I/O request to obtain in bucket
Less than token, only Q` I/O request can be added into request processing queue and be handled, and delete Q` token in bucket, in addition
R-Q` I/O request is in the medium token to be obtained of token waiting list.
