prom Buffer Priority Servicing

1.3.6.1.4.1.2167.3.7.1.1.7

The value of this object configures how often the normal priority queue is serviced relative to the high priority queue. By default, the normal priority queue is serviced every thousand frames(3). This means that the normal priority queue is guaranteed to be serviced after servicing, at most, one thousand high priority frames. It is important to service the normal priority queue for two reasons. One is to prevent starvation for frames on the normal priority queue. The other reason is that frames cannot be aged if they are not serviced (see the age timer).
