Field Description Interface...
  • Page 64 User Manual transmitted. The side effect is that a misconfigured stream can potentially take all bandwidth. PRIOWRR This is a priority based weighted round robin algorithm operating on CoS2-CoS6. CoS1 queues have the highest priority and are not controlled by the WRR algorithm. Of the three shaping algorithms available on the Shaper Configuration page, only one can be enabled at a time.
  • Page 65 User Manual Example 2: Low Latency Queue Discipline Enabled In this second example, Low Latency Queue Discipline is enabled. CoS1 is not rate controlled (hence the field is disabled). CoS2 takes 100 Kbps when there are no CoS1 packets. CoS6 has 300 Kbps when there is no CoS1 or CoS2 packets. This is similar to the HTB queue discipline as they are both rate-based algorithm, except that CoS1 is handled differently.
  • Page 66 User Manual Example 3: PRIOWRR Enabled In this third example, PRIOWRR is enabled. Since PRIOWRR operates only on the number of packets being transmitted, the max rate field has been disabled. Only percentage can be assigned to the CoS2 - CoS6. CoS1 is not rate controlled (hence the field is not displayed).
