If the value is zero, then there is effectively no max- imum rate limit and that the scheduler should attempt to be work-conserving for this queue. If the value is non-zero, the scheduler will limit the servicing of this queue to, at most, this rate in a non-work- conserving manner. Note that this attribute's value is coupled to that of dsMaxRateRelative: changes to one will affect the value of the other. [IFMIB] defines ifSpeed as Gauge32 in units of bits per second, and ifHighSpeed as Gauge32 in units of 1,000,000 bits per second. This yields the following equations: RateRelative = [ (RateAbsolute * 1000) / ifSpeed ] * 1,000 Where, 1000 is for converting kbps used by RateAbsolute to bps used by ifSpeed, 1,000 is for 'in units of 1/1,000 of 1' for RateRelative. or, if appropriate: RateRelative = { [ (RateAbsolute * 1000) / 1,000,000 ] / ifHIghSpeed } * 1,000 Where, 1000 and 1,000,000 is for converting kbps used by RateAbsolute to 1 million bps used by ifHighSpeed, 1,000 is for 'in units of 1/1,000 of 1' for RateRelative." ::= { dsMaxRateEntry 4 } dsMaxRateRelative OBJECT-TYPE SYNTAX Unsigned32 (1..4294967295) STATUS current DESCRIPTION "The maximum rate that a downstream scheduler element should allocate to this queue, relative to the max- imum rate of the interface as reported by ifSpeed or ifHighSpeed, in units of 1/1,000 of 1.
