filter-weight <weight>

The exponentially weighted moving average (EWMA) filter weight value. The default value is 9.

This value controls how quickly or slowly the WRED algorithm's average queue length tracks the queue actual queue length.

  • With a low filter-weight <weight> value, the computed average queue length will track the actual queue length quickly.
  • With a high filter-weight <weight> value, the computed average queue length will track the actual queue length slowly.
