Router Pools is an optional advanced topology for configuring VidyoRouters in the VidyoConferencing system. You can configure Router Pools at initial installation or do so at a later date when your organization’s network grows. Some of the benefits of Router Pools include:
- More efficient network bandwidth utilization.
- Improved latency for conferences by localizing traffic.
- Support for large conferences spanning over multiple VidyoRouters.
- Shared capacity with floating VidyoLine licenses among regions.
- Simplified firewall configurations.
The capacity of a single VidyoRouter is up to 100 concurrent HD lines. If you need additional capacity, you can purchase additional VidyoRouters. If you do, you can group them into pools or Router Pools. Typically you might do this to group VidyoRouters that are near each other geographically (e.g., group your American-based VidyoRouters in one pool and your European-based VidyoRouters into another pool). Another reason might be to reserve one or more VidyoRouters to a certain group of users in your organization (e.g., top level management).
- A VidyoRouter can be in only one pool.
- A pool contains one or more VidyoRouters.
- If you have only one VidyoRouter, it’s still in a pool.
- A location may have a number of pools.
- Multiple VidyoRouters in a pool provide failover across the pool.
Before setting Router Pools, if one VidyoRouter reached its saturation point of 100 simultaneous users for a conference, any additional connection attempts were refused even if a second VidyoRouter was hosting less than 100 users. There was no way the first VidyoRouter could utilize the second VidyoRouter’s unused capacity.
However, once your Router Pools are set up, when one VidyoRouter hits maximum capacity, instead of additional callers to the same conference failing to connect, they can be cascaded onto another VidyoRouter. If the second VidyoRouter maxes out, it can cascade to a third VidyoRouter in the pool and so on.
VidyoRouters within a single pool use the Full Mesh topology, whereas pools are cascaded using the DAG (Directed Acyclic Graph) topology. Directed edges of the DAG must be manually specified during system configuration. You must also assign a priority that will decide which two locations will connect when there is more than one choice.
This section describes how to create a VidyoRouter pool, how to remove a VidyoRouter from a pool, and how to delete an entire VidyoRouter pool.
