            9.3.2   User account and profile management

            The UAPM-F creates CSU's account with CSU's access information through I_UAM_UAPM. The UAPM-F has
            two more reference points I_CCM_UAPM and I_PA_UAPM for authentication with CSU's account information
            and for the pre-configured environments and profiles, respectively. When RAD-F allocates and distributes
            resources, the UAPM-F provides CSU's account information on I_UAPM_RAD or I_UAPM_OPM. Detailed
            functional description for the UAPM-F is specified in clause 7.3.2.

            9.3.3   Virtual desktop resource allocation and distribution

            The RAD-F has a reference point of MC-F through I_RAD_MC with monitoring information to analyse resource
            usage.  I_IAM_RAD  enables  the  RAD_F  to  approach  IAM-F  and  resource  assignment  function  (RA-F)  for
            resource assignment. A detailed functional description for the RAD-F is specified in clause 7.3.3.

            9.3.4   Operational policy management for DaaS
            The OPM-F has two reference points I_OPM_PM and I_OPM_MC to receive the performance or resource
            usage which is used to establish the policies. These policies are applied to PA-F with I_PA_OPM. A detailed
            functional description for the OPM-F is specified in clause 7.3.4.

            9.3.5   High availability for DaaS
            The HA-F has only the reference point with the MC-F through I_MC_HA in order to monitor the resource
            state  for  establishing  the  related  policies.  A  detailed  functional  description  for  the  HA-F  is  specified  in
            clause 7.3.5.

            9.3.6   Power management of virtual desktop resource
            The  PM-F  collects  performance  information  from  the  MC-F  through  I_MC_PM  and  transfers  the  power
            related information to the PA-F through I_PA_PM for efficient provisioning. A detailed functional description
            for the PM-F is specified in clause 7.3.6.


            9.4     Virtualization infrastructure functions
            The VI-FS has four functions including performance enhancement for virtualization platform function (PE-F),
            IAM-F,  RA-F,  and  platform  virtualization  function  (PV-F)  as  shown  in  Figure  9-4.  The  VI-FS  provide  the
            interfaces with the other two function groups, VDCD-FS and VDRM-FS.
