Load Balance

When there are multiple WAN interfaces, and when the bandwidth of one WAN connection is not enough for the traffic
loads from the Intranet to the Internet, the WAN load balance function can be considered to enlarge the total WAN
bandwidth.
3.1.4.1

Load Balance Strategy

There are three optional strategies for load balance: "By Smart Weight", "By Specific Weight", and "By User Policy". The
administrator can select strategy according to application requirement and environment status. The strategies are explained
as below.
3.1.4.2

By Smart Weight

Under this strategy, the router will take the line speed settings of all WAN interfaces specified on the "Physical Interface"
configuration page as the default ratio for data transfer. Based on the ratio of packets via these WAN interfaces in the past
period (e.g. 5 minutes), the system decides how many sessions will be transferred via each WAN interface for the next
period. The administrator may take it as a fast approach to maximize the bandwidth utilization of multiple WAN interfaces.
