Theory

Burst is a feature that allows to satisfy queue requirement for additional bandwidth even if required rate is bigger that MIR (max-limit) for a short period of time.

Burst can occur only if average-rate of the queue for the last burst-time seconds is smaller that burst-threshold. Burst must stop if average-rate of the queue for the last burst-time seconds is bigger or equal to burst-threshold

Burst mechanism is simple - if burst is allowed max-limit value is replaced by burst-limit value. When burst is disallowed max-limit value remains unchanged.


  1. burst-limit (NUMBER) : maximal upload/download data rate which can be reached while the burst is allowed
  2. burst-time (TIME) : period of time, in seconds, over which the average data rate is calculated. (This is NOT the time of actual burst)
  3. burst-threshold (NUMBER) : basically this is value of burst on/off switch.
  4. average-rate (read-only) : Every 1/16 part of the burst-time, the router calculates the average data rate of each class over the last burst-time seconds.
  5. actual-rate (read-only) : actual traffic transfer rate of the queue

Values:

limit-at=1M

max-limit=2M

burst-threshold=1500k

burst-limit=4M
