Resource pool load balancing and backup of VP98 series MCUs

Hi, user_3433189!

Welcome to our community!

The VP98 series MCU has the load balancing and backup capabilities in resource pools.

The resource pool load balancing and backup of VP98 series MCUs are described as follows:

In a large-scale video conferencing networking scenario, multiple MCU ports can be virtualized into a unified port resource pool to enable unified resource provisioning. This function shares MCU port resources across regions, reducing port resource construction costs.

• Resource pool backup: intra-pool and inter-pool MCU backup

• Port load balancing: The MCU with the most available ports is selected preferentially to hold conferences

• Maximum port usage: When a single MCU has limited resources in a region, two MCUs with the most available resources in the region are selected preferentially to hold conferences

Load balancing and automatic cascading:

1. The MCU with the most available resources in the MCU resource pool is selected preferentially for site accessing.

2. If the resources of a single MCU in a region are insufficient, the MCU with the most available resources in the region is selected preferentially for cascading.

Flexible conference backup:

1. The MCU that holds the conference is faulty.

2. Intra-pool backup: The system automatically switches the conference to other MCU in the same service area.

3. Inter-pool backup: When all the MCUs in a service area are faulty, the system automatically switches the conference to the backup service area.
