Scheduling Capacity
You can tune the scheduling capacity of the DMA system that the
RealPresence Resource Manager system relies on. You do this through the
RealPresence Resource Manager system.
The number of ports used for a conference can vary according to the MCU that
hosts the conference and the number/type of endpoints that join. Because
schedulers can only choose from a pre-configured DMA system pool order
when scheduling pooled conferences, they rely on an administrator to tune the
DMA system’s scheduling capacity to ensure efficient use of resources.
There are three ways an administrator can assess DMA system scheduling
capacity:
• View conference reports from the DMA system. This method is preferred
and provides the most accurate information.
• Monitor ongoing conferences to assess if resources were underbooked.
• View information on RealPresence Resource Manager CDR reports to
review ports used for individual conferences.
Polycom recommends setting the DMA system scheduling capacity more
conservatively at first and then tuning for increased conference activity. See
“Edit a Polycom DMA System” on page 314.
Working with a Polycom DMA System
You can integrate your RealPresence Resource Manager system with a
Polycom DMA system. This section includes these topics:
• “DMA View” on page 312
• “Add a Polycom DMA System” on page 313
• “Edit a Polycom DMA System” on page 314
• “Delete a Polycom DMA System” on page 314
DMA View
Use the DMA View to view Polycom DMA systems v5.0 or later. You can
integrate your RealPresence Resource Manager system with these later
versions of the DMA system for both call server (gatekeeper and SIP
proxy/registrar) and MCU pool order capability.
The DMA system list has the following information.
