Resource Capacities in AVC CP, SVC and Mixed Mode Conferences
When viewing the Collaboration Server resource report for mixed CP and SVC conferences, the resource
allocations are described in AVC HD720p30 units. A port ratio of 1 AVC HD port will equal 2 AVC SD ports,
which equals 3 SVC ports (in a non-mixed conference). When the Collaboration Server is reporting the
available capacity, it will appropriately round up the remaining capacity to the nearest whole value of
available ports. For example, one SVC endpoint in a conference is equal to 1/3 of the resource value. The
resource report displays this as one full resource used. Two SVC endpoints is equal to 2/3 of the resource
value. Therefore, the resource report displays this as one full resource used, and so forth. The following
tables show the actual resource capacity utilization for both CP only and mixed CP and SVC conferences

MCU Resource Management by RealPresence Resource Manager
(XMA), Polycom CMA and Polycom RealPresence DMA System
When the RealPresence Resource Manager (XMA), Polycom CMA and Polycom RealPresence DMA
system are part of the solution, following a request by the RealPresence Resource Manager (XMA),
Polycom CMA or Polycom RealPresence DMA system, 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
Collaboration Server
resources by the RealPresence Resource Manager (XMA),
Polycom CMA and Polycom RealPresence DMA system.
Guidelines
●
Following requests sent by
CMA
and
RealPresence
DMA
system, the
Collaboration Server
will send
the number of occupied resources for a conference or total for the MCU.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
.
●
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
Collaboration Server
is unaware of the resource usage split between the
CMA
and
RealPresence
DMA
system.
Port Usage Threshold
The
Collaboration Server
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 Gauge
in the
Status Bar
of the
Collaboration Server Web Client
.
