      In the Simple Abstract Model a connection is assigned a priority
         when it is established.  It may be assumed that for connections
         that share the same output port, a cell or frame on a
         connection with a higher priority is much more likely to exit
         the switch before a cell or frame on a connection with a lower
         priority if they are both in the switch at the same time.

      The QoS Profile Model provides a simple mechanism that allows QoS
         semantics defined externally to GSMP to be assigned to
         connections.  Each profile is an opaque indicator that has been
         predefined in the controller and in the switch.

4. Summary of Message Set

   The following table gives a summary of the messages defined in this
   version of the specification.  It also makes a recommendation of the
   minimal set of messages that should be supported in an MPLS
   environment.  These messages will be labelled as "Required", though
   the service provided by the other messages are essential for the
   operation of carrier quality controller/switch operations.  GSMPv1.1
   or GSMPv2 commands that are no longer support are marked as
   "Obsolete" and should no longer be used.

5. Security Considerations

   The security of GSMP's TCP/IP control channel has been addressed in
   [4].  For all uses of GSMP over an IP network, it is REQUIRED that
   GSMP be run over TCP/IP using the security considerations discussed
   in [4].
