MCU Resource Management by RealPresence Resource Manager (XMA),
Polycom CMA and Polycom DMA
When the RealPresence Resource Manager (XMA), Polycom CMA and Polycom DMA are
part of the solution, following a request by the RealPresence Resource Manager (XMA),
Polycom CMA or Polycom DMA, the
MCU
will send updates on resource usage to both
CMA
and
DMA,
with each application
updating its own resource usage for the
MCU
. This
provides better management of the
RMX
resources by the RealPresence Resource Manager
(XMA), Polycom CMA and Polycom DMA.
Guidelines
•
Resource usage updates from
RMX
to the
CMA
and
DMA
are supported only with
RMX
s with
MPM+
or
MPMx
cards.
•
Both
Flexible Resource Capacity
™ and
Fixed Resource Capacity
™ modes are supported
with DMA.
•
Only
Flexible Resource Capacity
™ mode is supported with CMA.
•
Following requests sent by
CMA
and
DMA
, the
RMX
will send the number of occupied
resources for a conference or total for the MCU, according the
Resource Capacity Mode
used by the system.
—
In
Flexible Resource Capacity Mode
,
CMA/DMA
receive information about how many
Video
(
CIF
) and
Audio
resources are occupied per conference or MCU according the
request type sent by the
CMA
and
DMA
.
—
In
Fixed Resource Capacity™ Mode
,
DMA
receives information about the number of
occupied resources per resource type (Audio Only, CIF, SD, HD 720p, HD 1080p)
and per conference or MCU according the request type sent by the
DMA
.
•
Occupied resources are resources that are connected to ongoing conferences.
Disconnected endpoints in an ongoing conference are not counted as occupied
resources.
•
An ongoing conference that does not include participants and the
Send Content to Legacy
Endpoints
option is disabled does not occupy resources. If the
Send Content to Legacy
Endpoints
option is enabled, the conference occupies one SD resource.
•
The
RMX
is unaware of the resource usage split between the
CMA
and
DMA
.
Port Usage Threshold
The
RMX
can be set to alert the administrator to potential port capacity shortages. A
capacity usage threshold can be set as a percentage of the total number of licensed ports in
the system.
When the threshold is exceeded, a
System Alert
is generated.
The default port capacity usage threshold is 80%.
The administrator can monitor the MCU’s port capacity usage via the
Port Gauges
in the
Status Bar
of the
RMX Web Client
.
