ABSTRACT:
Packets of data from multiple queues are transferred onto a single channel. Each queue has associated with it a data rate for servicing a packet within the queue. Each queue has an integer that, relative to the other numbers, represents is inversely related to the assigned data rate. Each queue has associated with it a counter and that is loaded with its corresponding integer. The counter values are compared, and the queue corresponding to the lowest counter value has a packet coupled to the channel. The counter of the selected queue is incremented by its integer. The next queue that is selected is the one that corresponds to the counter with the lowest count value after the counter that corresponds to the previously selected queue has been updated.
