// BufferPool
// ===================================================================
   [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.") ]
class CIM_BufferPool : CIM_CollectionOfMSEs {

         Description (
         "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.") ]
    string CollectionID;

        [Key, MaxLen (256), 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.") ]

        [Description (
         "This property is a 32-bit unsigned integer, and defines "
         "the 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.") ]

         "simultaneously allocated to multiple instances of "

class CIM_MPLSBuffers : CIM_BufferPool {

        [Description (
         "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 the MAM can be chosen so that a resource "
         "can be under-allocated or over-allocated. A resource is "
         "said to 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. "

        [Description (
         "This property describes the resource classes that a "
         "buffer resource belongs to. In general, a resource "
         "can be assigned to more than one resource class, since "
         "the classes are coded in the individual bits of the "
         "property. 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.") ]
