We have added load balancing to Flashphoner Web Call Server product.
With the load balancing feature you can allocate your users between several server nodes.

Implementation includes:
1. Load statistics HTTP interface that returns full system info including count of simultaneous calls, CPU usage, memory usage etc.
2. Simple load balancer that works on one of the server nodes and requests another nodes by HTTP.
The simple load balancer selects the least loaded server based on count of simultaneous calls.
3. Flash client side has additional setting and requests this URL to get the least loaded server.

You can also implement your own load balancing logic using HTTP statistics interface.
To setup the load balancer, please follow the load balancing doc.

Kind regards.
Flashphoner team
