      Hi guys.

      I have the following setup here:

      WAN (HFSC - 350Mb)
      --qInternet (limit: 500 - sched: codel - bw: 330Mb - ul m2: 330Mb - ls m2: 330Mb)
      ----qDNS (limit: 500 - sched: codel - bw: 5% - ls m2: 5%)
      ----qBulk (limit: 600 - sched: codel - bw: 26% - ls m2: 26%)
      ----qACK (limit: 500 - sched: codel - bw: 20% - ls m2: 20%)
      ----qVoip (limit: 500 - sched: NA - bw: 5% - rt m2: 2% - ls m2: 5%)
      ----qMeet (limit: 500 - sched: codel - bw: 27% - ls m2: 27%)
      ----qTech (limit: 500 - sched: codel - bw: 5% - ls m2: 5%)
      ----qLive (limit: 500 - sched: codel - bw: 2% - ls m2: 2%)
      ----qDefault (limit: 500 - sched: default - codel - bw: 10% - ls m2: 10%)

      LAN (HFSC - 1Gb)
      --qInternet (limit: 500 - sched: codel - bw: 330Mb - ul m2: 330Mb - ls m2: 330Mb)
      --qLink (limit: 500 - sched: default - red - bw: 10% - ls m2: 10%)
      ----qDNS (limit: 500 - sched: codel - bw: 5% - ls m2: 5%)
      ----qBulk (limit: 600 - sched: codel - bw: 26% - ls m2: 26%)
      ----qACK (limit: 500 - sched: codel - bw: 20% - ls m2: 20%)
      ----qVoip (limit: 500 - sched: NA - bw: 5% - rt m2: 2% - ls m2: 5%)
      ----qMeet (limit: 500 - sched: codel - bw: 27% - ls m2: 27%)
      ----qTech (limit: 500 - sched: codel - bw: 5% - ls m2: 5%)
      ----qLive (limit: 500 - sched: codel - bw: 2% - ls m2: 2%)

      What I would like to understand and try to apply is the RT condition on qMeet queue.

      If I set for an example, 5% on qMeet rt m2. What is the expected behavior? All the connections flowing through this queue will have at a minimum this 5% or the rt m2 5% will be shared amongst all the connections?

      This queue is to handle Google Meet, MS Teams and so on, and I would like to make sure the necessary bandwidth will be available when the client needs it.

      Another strange behavior happening sometimes here is, when the link is saturated the internet goes down for everybody for at least 30 seconds.

      Thanks in advance.
