Load Balancing
Load Balancing is an optional licensed feature. For an overview of Nomadix load balancing and common use
cases, see
Load Balancing and Link Failover
on page 27.
The NSE can balance subscriber assignment between all active WAN interfaces when Load Balancing mode
is enabled. Note that subscribers are balanced, not traffic.
As subscribers go valid, they are assigned to a WAN interface, taking account of both the Uplink bandwidth
settings of the interfaces and the number of subscribers currently using each interface. Higher bandwidth
settings will mean more subscribers will be assigned to that interface. The subscriber will use the assigned
interface for all traffic.
If a WAN interface goes down, the subscribers currently assigned to that interface will be reassigned to the
remaining interfaces. Once that interface is restored, current subscribers will NOT be reassigned, but new
subscribers can be assigned to that interface (in accordance with the load balancing algorithm).
An NSE reboot will rebalance all subscribers.
Subscribers will use the IP address of their WAN port (or assigned additional NAT address) for their DAT
sessions.
To configure load balancing, choose
Configuration
>
Load Balancing
.
You can choose to trigger the Load Balancing / Failover feature either by the link status of the port(s) or by
the active Interface Monitoring feature.
When either Interface Monitoring or link status is used, WAN ports will be characterized as either Available
or Unavailable. If Load Balancing is configured to use Interface Monitoring but Monitoring itself is not
configured, the status will be Unknown.
Using Link state will provide a faster response, but using Interface Monitoring will assure that there is internet
access through that port before assigning subscribers to it.
Run Time Status gives a useful summary of all Load Balancing settings and subscriber distribution.
