 * 5.4.  QoS-Semantics

   The QoS-Semantics AVP (AVP Code 575) is of type Enumerated and
   provides the semantics for the QoS-Profile-Template and QoS-
   Parameters AVPs in the Filter-Rule AVP.

   This document defines the following values:

    (0): QoS-Desired
    (1): QoS-Available
    (2): QoS-Delivered
    (3): Minimum-QoS
    (4): QoS-Authorized

   The semantics of the QoS parameters depend on the information
   provided in the list above.  The semantics of the different values
   are as follows:

   Object Type    Direction   Semantic
   ---------------------------------------------------------------------
   QoS-Desired     C->S       Client requests authorization of the
                              indicated QoS.
   QoS-Desired     C<-S       NA
   QoS-Available   C->S       Admission Control at client indicates
                              that this QoS is available. (note 1)
   QoS-Available   C<-S       Admission Control at server indicates
                              that this QoS is available. (note 2)
   QoS-Delivered   C->S       Client is reporting the actual QoS
                              delivered to the terminal.
   QoS-Delivered   C<-S       NA
   Minimum-QoS     C->S       Client is not interested in authorizing
                              QoS that is lower than the indicated QoS.
   Minimum-QoS     C<-S       Client must not provide QoS guarantees
                              lower than the indicated QoS.
   QoS-Authorized  C->S       NA
   QoS-Authorized  C<-S       Server authorizes the indicated QoS.

   Legend:

     C: Diameter client
     S: Diameter server
     NA: Not applicable to this document;
         no semantic defined in this specification
         
     Notes:

     (1) QoS-Available in this direction indicates to the server that
         any QoS-Authorized or Minimum-QoS must be less than this
         indicated QoS.

     (2) QoS-Available in this direction is only useful when the AAA
         server performs admission control and knows about the resources
         in the network.
