简答题WRR和SRR的区别是什么？
  • （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.
