My new 65xx line card documentation says it supports deficit weighted round-robin (DWRR). What is DWRR and what does it mean?
A. DWRR transmits from the queues without starving the low-priority queue, because it keeps track of low-priority queue under-transmission and compensates for it in the next round. If a queue is not able to send a packet because its packet size is larger than the available bytes, then the unused bytes are credited to the next round.
