-- If there is ambiguity between classifier elements of different
-- classifier, classifier linkage order indicates their precedence;
-- the first classifier in the link is applied to the traffic first.

    DESCRIPTION
       "The type of algorithm used by this dropper. A value
       of tailDrop(2), headDrop(3), or alwaysDrop(5) represents
       an algorithm that is completely specified by this PIB.

       A value of other(1) indicates that the specifics of
       the drop algorithm are specified in some other PIB
       module, and that the dsAlgDropSpecific attribute
       points to an instance of a PRC in that PIB that
       specifies the information necessary to implement the
       algorithm.

       The tailDrop(2) algorithm is described as follows:
       dsAlgDropQThreshold represents the depth of the
       queue, pointed to by dsAlgDropQMeasure, at
       which all newly arriving packets will be dropped.

       The headDrop(3) algorithm is described as follows: if
       a packet arrives when the current depth of the queue,
       pointed to by dsAlgDropQMeasure, is at
       dsAlgDropQThreshold, packets currently at the head of
       the queue are dropped to make room for the new packet
       to be enqueued at the tail of the queue.

       The randomDrop(4) algorithm is described as follows:
       on packet arrival, an algorithm is executed which may
       randomly drop the packet, or drop other packet(s)



       from the queue in its place.  The specifics of the
       algorithm may be proprietary.  For this algorithm,
       dsAlgDropSpecific points to a dsRandomDropEntry
       that describes the algorithm.  For this
       algorithm, dsAlgQThreshold is understood to be
       the absolute maximum size of the queue and additional
       parameters are described in dsRandomDropTable.

       The alwaysDrop(5) algorithm always drops packets. In
       this case, the other configuration values in this Entry
       are not meaningful; The queue is not used, therefore,
       dsAlgDropNext, dsAlgDropQMeasure, and
       dsAlgDropSpecific should be all set to zeroDotZero.

       The mQDrop(6) algorithm measures multiple queues for
       the drop algorithm.  The queues measured are represented
       by having dsAlgDropQMeasure referencing a dsMQAlgDropEntry.
       Each of the chained dsMQAlgDropEntry is used to describe
       the drop algorithm for one of the measured queues."

-- Scheduler Table
--
--
-- The Scheduler Table is used for representing packet schedulers:
-- it provides flexibility for multiple scheduling algorithms, each
-- servicing multiple queues, to be used on the same
-- logical/physical interface of a data path.
--
-- Notice the servicing parameters the scheduler uses is
-- specified by each of its upstream functional data path elements,

-- The coordination and coherency between the servicing parameters
-- of the scheduler's upstream functional data path elements must
-- be maintained for the scheduler to function correctly.
--
-- The dsSchedulerMinRate and dsSchedulerMaxRate attributes are
-- used for specifying the servicing parameters for output of a
-- scheduler when its downstream functional data path element
-- is another scheduler.
-- This is used for building hierarchical queue/scheduler.
