Load Balancing
Network > Load Balancing
Load balancing is a mechanism that enables balancing traffic between various links. It distributes traffic
among various links, optimizing utilization of all the links to accelerate performance and cut operating
costs. The order of Interface priority depends on the metric assigned to the interface.
a. How it works
Load balancing is determined by the load metric i.e. weight. Each link is assigned a relative weight and
Router distributes traffic across links in proportion to the ratio of weights assigned to individual link. This
weight determines how much traffic will pass through a particular link relative to the other link.
Administrator can set weight and define how the traffic should be directed to providers to best utilize
their bandwidth investments. Weight can be selected based on:
•
Link capacity (for links with different bandwidth)
•
Link/Bandwidth cost (for links with varying cost)
Note
•
The default configuration of load balancer is in Failover Mode with the highest priority
given to WAN, followed by WWAN and followed by Cellular.
