Load-balancing through DNS round-robin¶

You can distribute load across several nodes using DNS round-robin.
Originating customers should be configured to a cluster domain name and should use DNS for each outgoing call.

Requirements:¶

• node count: 2+
• setup records in your DNS zone to spread load using round-robin
• specify domain name in connection form for your customers
• notify customers about usage of DNS lookup for each call
• IP address count in data center = node count

Limitations¶

• not every equipment supports DNS lookup.
  Therefore, you won't spread load for those of customers, which doesn't support this feature.
