MCU Selection Process

Note

MCU pools and pool orders are not used to select an ISDN gateway for simplified gateway dialing. See “ISDN Gateway Selection Process” on page 147.

The process below can be affected by the mechanisms that the system uses for detecting and handling MCU availability and reliability issues. See “MCU Availability and Reliability Tracking” on page 160.

The Polycom DMA system chooses an MCU for a user’s conference by applying the following rules in order:

1Select the MCU pool order:

a Use the pool order directly assigned to the user’s conference room.

bIf none, use the highest priority pool order associated with any group to which the user belongs.

cIf none, use the system default.

2Select the first MCU pool in the MCU pool order.

3Select the best MCU in the MCU pool, based on how well their capabilities fulfill the user’s needs in the following respects:

MCU has RMX profile required by user’s conference template.

MCU has IVR service required by user’s conference template.

MCU has recording capability required by user’s conference template.

If there are multiple MCUs that are equally capable, select the least used, as determined by the following formula:

port_availability = (free_video_ports / total_video_ports) + (0.0001 * free_audio_ports / total_audio_ports)

mixer_availability = (total_video_ports - 2 *

active_dma_conferences) / total_video_ports + 0.0001 * (total_audio_ports - 2 * active_dma_conferences) / total_audio_ports

availability = min (port_availability, mixer_availability)

4If no MCUs in the selected MCU pool have capacity, select the next MCU pool in the pool order and return to step 3.
