The minimum rate that a downstream scheduler element should allocate to this queue, relative to the maximum rate of the interface as reported by ifSpeed or ifHighSpeed, in units of 1/1000 of 1. If the value is zero, then there is effectively no minimum rate guarantee. If the value is non-zero, the scheduler will assure the servicing of this queue to at least this rate.

Note that this attribute value and that of diffServMinRateAbsolute are coupled: changes to one will affect the value of the other. They are linked by the following equation, in that setting one will change the other:

diffServMinRateRelative = (diffServMinRateAbsolute*1000000)/ifSpeed

or, if appropriate:

diffServMinRateRelative = diffServMinRateAbsolute/ifHighSpeed
