3.5 Load balancing for ENUM Queries

Bind9 load balances the ENUM queries between the available vENUM servers. It uses response times from previous queries to select the server that is likely to respond sooner. Dynamic adjustment of the recorded response times ensures that all forwarders are queried, including the ones with slower response times.

Note:

Load Balancing is handled by BIND9, no external load balancer has been introduced.
