but not received any response packet during a detection period, it will consider that the
connection is faulty.
For a faulty Internet connection, the detection mechanism is as follows: Similarly, the
Gigabit Router also periodically sends a detection packet at the specified time interval to
the target IP address. Once more than half of the response packets received during a
detection period, the Gigabit Router will consider that the connection is back to normal
and enable it immediately. For example, when the
Retry Times
is set to 5, if the Gigabit
Router has sent five consecutive detection packets and received three or more packets
during a detection period, it will consider that the connection is back to normal.
On the Gigabit Router, you can assign a preferential Internet connection to some local
computers in advance by setting the connection’s
Start Internal IP
and
End Internal IP
,
thus the computers in the specified address range will preferentially use the assigned
Internet connection to access the Internet. If the assigned Internet connection is normal,
those computers can only use it to access the Internet. Else, they will use other normal
Internet connections to access the Internet.
Note
If you don’t want to monitor an Internet connection, please leave its
Detection
Interval
at the default value of 0.
5.2.1.2 Load Balancing Mode
The Gigabit Router provides two connection groups: primary connection group and
backup connection group. An Internet connection in the primary connection group is a
primary connection, while an Internet connection in the backup connection group is a
backup connection. By default, all the Internet connections are primary connections. You
can move one or more connections into the backup connection group if needed.
The Gigabit Router provides two load balancing modes:
Full Load Balancing
and
Partial
Load Balancing
.
If you choose to use
Full Load Balancing
, all the Internet connections are used as
primary connections. The working principle is as follows:
1. If all the Internet connections are normal, the LAN users will use these connections to
access the Internet.
2. If an Internet connection is faulty, the Gigabit Router will shield it immediately, and the
traffic through the faulty connection will be distributed to other normal connections
automatically.
3. Once the faulty connection is back to normal, the Gigabit Router will enable it
immediately, and the traffic will be redistributed automatically.
If you choose to use
Partial Load Balancing
, some Internet connections are used as
