through the faulty connection will be distributed to other normal connections
automatically.
3. Once the faulty connection is back to normal, the Device 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
primary connections, and others are used as backup connections. The operation principle
is as follows:
1. As long as one or more primary connections are normal, the LAN users will use the
primary connection(s) to access the Internet. In this case, if there is more than one
primary connection, the Device will control and balance the traffic among these
connections.
2. If all the primary connections are faulty, it will automatically switch to the backup
connection(s) to let the LAN users use them to access the Internet. In this case, if
there is more than one backup connection, the Device will control and balance the
traffic among these connections.
3. Once one or more faulty primary connections are back to normal, it will automatically
switch back to the primary connection(s).
Note
During connections switching, some user applications (such as some online games)
may be interrupted unexpectedly due to the nature of TCP connection. UTT
Technologies Co., Ltd. will not bear all the losses and legal
proceedings caused by it.
6.3.1.3 Internet Connection Detection Method
The Device provides three detection methods: ICMP, ARP and DNS. It allows you to
select one of them to monitor the Internet connections. Note that you can only select a
single Detection Method for all the Internet connections, but can set different
Detection
Target, Detection Interval, and Retry Times for each Internet connection respectively.
The
descriptions of each detection mode are as follows:
Ɣ ICMP: The Device will monitor an Internet connection by sending ICMP echo request
packets the target IP address you specify. In this case, the target IP address can be
either the connection¶s default gateway IP address or another public IP address you
specify.
