"backup line" group are collectively known as backup line. All lines are main lines by default.
Users can divide some lines into the "Backup line" group as needed.
The device provides two line combination modes, "All line load balancing" and "Partial line load
balancing while the other backed up".
In the "All line load balancing" mode, all lines are used as main lines. Working principles are as
follows:
1.
When all lines are normal, the Intranet hosts can use all lines for Internet access
simultaneously.
2.
If a line fails, it should be shielded immediately, and the flow originally passing through the
line will be allocated to the other lines.
3.
Once the fault line is restored to normal, the device will enable this line automatically, and
the flow is automatically redistributed.
In the "Partial line load balancing while the others backed up" mode, part of the lines are used as
main lines, the other part of the lines is used as backup lines. Working principles are as follows:
1.
As long as the main line is normal, the Intranet hosts use main lines for Internet access.
2.
If the main line fails, it will automatically switch to using the backup line for Internet access.
3.
Once the fault lines are restored to normal once, they will be immediately switched back to
the main line.
Tip:
When a line is interrupted for line switching, some user applications (such as part of network
games) may be unexpectedly interrupted. This is determined by the TCP session property.

Global Settings
In these two line combination modes, "All line load balancing" and "Partial line load balancing
while the others backed up", the interface of global setting is different; therefore, their universal
setting parameters are described below respectively.
