第3题: [简答题]WRR和SRR的区别是什么? 参考答案:
(1)While on every scheduler round WRR empties each queue up to the maximum number of allowed packet, before switching to the next queue;SRR performs a series of quick runs each round, deciding on whether to de-queue a packet from the particular queue (based on queue weights).
(2)SRR of shared mode achieves more “fairness” on per-round basis than WRR.
(3)In shaped mode of SRR, bandwidth of the egress queue is limit by the weight; While using WRR, bandwidth of the queue is guaranteed to the weight by not limit to it.
