3.1.5 Load Balance
When there are more than one WAN interfaces, and when the bandwidth of one WAN connection
is not enough for the traffic loads from the Intranet to the Internet, the gateway device needs the
WAN load balance function to enlarge the total WAN bandwidth of gateway.
AMIT "Load Balance" function for multiple WANs gateway designs five optional strategies: By
Smart Weight, By Priority, By User Policy, By Sequence
9
and By Latency
1
. Administrator can choose
strategy based on his immediate need and environment consideration.
In "Load Balance" page, there is the "Configuration" window for you to enable the load balance
function and specify preferred balance strategy. There will be "Priority Definition" window when the
"By Priority" is selected from the load balance strategy dropdown box. If you select the "By User
Policy" the window of "User Policy List" and "User Policy Configuration" will become available
configuration. Please be noted that "By Smart Weight" has not further configuration window.
Load Balance Configuration
The "Configuration" window is to enable the load balance function and specify the strategy. When
you choose "By Smart Weight" strategy, system will operate load balance function automatically based
on the embedded Smart Weight algorithm. However, when you choose "By Priority" strategy, the
further "Priority Definition" configuration window will let you define the ratio of transferred sessions
between all WAN interfaces for data transfer. At last, when you choose "By User Policy" strategy, the
further "User Policy List" shows all defined user policy entries, and the "User Policy Configuration"
window will let you create and define one user policy for routing dedicated packet flow via one WAN
interface.
By Smart Weight Load Balance Strategy
For "By Smart Weight" load balance strategy, system will operate the function automatically
without special configuration parameters, except the obtained available bandwidth (Line Speed) of
each WAN interface in advance, please see [Basic Network] ‐ [WAN] ‐ [Physical Interface] . System
