2.1.3 Load Balance
When there aremultiple 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.
Load Balance Strategy
There are three optional strategies for load balance:
“By Smart Weight”
, “
By Specific Weight”
, and “
By User
Policy”
. Administrator can select strategy according to application requirement and environment status. The
strategies are explained as below.
By Smart Weight
If based on "By Smart Weight" strategy, gateway
will take the line speed settings of all WAN
interfaces specified in "Physical Interface"
configuration page as default ratio for data
transfer. Based on the ratio of packet bytes via
these WAN interfaces in past period (maybe 5
minutes), system decides how many sessions will
be transferred via each WAN interface for next
period.
Administrator may take it as a fast
approach to maximize the bandwidth utilization of
multiple WAN interfaces in gateway
