time traffic between the real time queues the impact of this point is that there is an advantage for weights to be reconfigurable for real time queues 3 the cell loss statistics of non real time queues are not significantly affected by the bandwidth allocation to real time queues in the range u03c3pcr lr lr line rate the significance of this point is that bandwidth may be allocated to non real time queues assuming that only u03c3pcr were allocated to the real time queues 1 the allocation of bandwidth to real time queues may not exceed lr 2 the allocation of bandwidth to non real time queues may not exceed lr u03c3pcr of real time queues 3 cac must communicate to wfq control the bandwidth requirement and u03c3pcr for real time queues 4 although the observation 1 would suggest that an assignment of lr to all real time queues may be sufficient i e a time increment value of zero to each real time queue and therefore exhaustive round robin between real time queues observation 2 indicates that benefit can be derived from actively setting the weights on real time queues it follows from design requirement 3 that real time queues.
