摘要： Access requests to a database are monitored for average time taken to fulfill the requests and whether a queue of unfulfilled requests is building up beyond an acceptable threshold. When the queue has built up beyond the acceptable threshold and/or when the average time taken to fulfill the requests has exceeded a delay threshold value, database access requests may be rejected. In one advantageous aspect, a graceful degradation in performance may be achieved by selectively rejecting access requests of a lower priority and favoring access requests of a higher priority for execution.

摘要： Whether video advertisements are being delivered to a human user or a machine is determined passively, i.e., without having the user to perform any explicit actions. Based on the time and frequency of ad requests generated from a user device, a daily schedule is estimated for the user. The estimated daily schedule is compared with a daily schedule pattern to determine whether the user is a human user or not.
