Gaining Priority Based on Time in Queue

focuscon

大家看看这个模型可以用在解决哪类问题上？
Items serviced according to a priority are subject to  "aging in queue" (i.e., other items entering at higher priority may "hog" the server).  A typical protocol to address this problem is to have items gain priority by periodically checking aggregate time on queue.
