// Description: The Network Model extends the management concepts to
//              represent protocol interfaces and network/protocol
//              services.  This file defines the classes to manage
//              network buffers.
// 
//              The object classes below are listed in an order that
//              avoids forward references. Required objects, defined
//              by other working groups, are omitted.
// ==================================================================
// Change Log for v2.8
// CR1061 - Add MPLSBuffers and MPLSBufferEndpointBuffers classes
// 
// Change Log for v2.7
// CR790 - Add classes to support MPLS
// CR982 - MPLS classes remain as Experimental for CIM V2.8

   [Version ("2.6.0"), Description (
       "This class represents the use of buffers by a Queuing "
       "Service.  The existence and management of individual buffers "
       "will be modeled in a future release.  At the current level of "
       "abstraction, modeling the existence of the BufferPool is "
       "necessary.  Long term, it is not sufficient.\n"
       "\n"
       "In implementations where there are multiple buffer sizes, an "
       "instance of BufferPool should be defined for each set of "
       "buffers with identical or similar sizes.  These instances of "
       "buffer pools can then be grouped together using the "
       "CollectedBuffersPool association.\n"
       "\n"
       "Note that this class is derived from CollectionOfMSEs, and not "
       "from Forwarding or ConditioningService.  BufferPool is only a "
       "collection of storage, and is NOT a Service.") ]

          "This property is defined in the CollectionOfMSEs class, but "
          "is overridden here to serve as part of the (composite) key "
          "that identifies the BufferPool instance."), 
       MaxLen (256) ]
   string CollectionID;

      [Key, Description (
          "CreationClassName indicates the name of the class or the "
          "subclass used in the creation of an instance.  When used "
          "with the other key properties of this class, this property "
          "allows all instances of this class and its subclasses to be "
          "uniquely identified."),

          "number of buffers in the Pool that are currently not "
          "allocated to any instance of a QueuingService.  Buffers "
          "allocated to a QueuingService could either be in use "
          "(containing packet data), or allocated to a Queue pending "
          "the arrival of new packet data.") ]
   uint32 AvailableBuffers;

          "The maximum allocation multiplier (MAM) determines the "
          "proportion of the buffer resource that is available for "
          "allocation to MPLS tunnels/traffic trunks.  The value of "

          "be under-allocated if the aggregate demands of all traffic "
          "trunks that can be allocated to it are always less than the "
          "capacity of the resource.  A resource is said to be "
          "over-allocated if the aggregate demands of all traffic "

          "32-bit vector, and the classes are described in [RFC2702].  "

          "\n"
          "Resource classes can be used to implement a variety of "
          "policies.  From a Traffic Engineering perspective, they can "
          "be used to implement policies with regard to both traffic "
          "and resource oriented performance optimization.  For "
          "example, resource class attributes can specify the relative "
          "preference of sets of resources for path placement of "
          "traffic trunks; explicitly restrict the placement of "
          "traffic trunks to specific subsets of resources; etc.") ]
