Hi Folks, I'm still confused on Cisco's Terminology and just want to clarify something again.
We all know that priority queuing is the strictest form of queuing, in the sense that the 'lower' queues have to defer / wait until the 'superior' queues have been drained, before they (the lower queues) can be serviced. But then what should I take this to mean? (Excerpt from the QoS guide):- --------------------------- IP RTP Priority The IP RTP Priority feature provides a strict priority queueing scheme that allows delay-sensitive data such as voice to be dequeued and sent before packets in other queues are dequeued. This feature can be used on serial interfaces and Frame Relay PVCs in conjunction with either WFQ or CBWFQ on the same outgoing interface. In either case, traffic matching the range of UDP ports specified for the priority queue is guaranteed strict priority over other CBWFQ classes or WFQ flows; packets in the priority queue are always serviced first. --------------------------- Should I take it to mean that all queuing schemes such is RTP and LLQ, which use a variant of WFQ as their basis have (1) 'modified' one queue to be act as a HIGH PQ, or if you like, System Queue 0 in custom queuing, in that it has to be drained first, before the other queues get serviced or (2) is it once again, a case of one queue having a higher weight which means more data gets sent, (but not all data), at each pass. My take on "Strict Priority queuing" and "Guaranteed Strict Priority" is that once again that specific queue's have to be emptied completely, before other queue's get serviced, and then and only then does WFQ / CBWFQ do it's thing on the interface Thanks for your insights into this as Cisco's terminology is driving me kooky!
