6.3 Load Balancing
This section describes the Basic > Load Balancing page. Note that only after you have
configured more than one Internet connections, the second level menu Load Balancing
will be displayed.
When using multiple Internet connections, you can configure load balancing related
parameters, such as, load balancing policy, load balancing mode, detection method,
detection interval, retry times, and ID binding, and so on.
6.3.1 Introduction to Load Balancing and Failover
6.3.1.1 Internet Connection Detection Mechanism
When using multiple Internet connections, the Device should has the ability of real-time
monitoring each Internet connection, and the network will not be interrupted even a
connection is faulty. To this end, we design flexible automatic detection mechanism on the
Device, and provide multiple detection methods to meet the actual requirements.
For the sake of convenience, we firstly introduce several related parameters including
Detection Target IP
,
Detection Interval
,
Retry Times
, and
Detection Period
.
Ɣ Detection Target IP: It indicates the IP address of a target device. The Device will
monitor an Internet connection by sending the detection packets to the specified
target IP address.
Ɣ Detection Interval: It indicates the time interval at which the Device periodically
sends detection packets, one packet at a time. The default value is 1000 milliseconds.
Especially, if you don¶t want to monitor an Internet connection, please set it to 0.
Ɣ Retry Times: It indicates the number of retries per detection period. The default
value is 3.
Ɣ Detection Period: It indicates a period of time during which the Device detects
whether the Internet connection is available or not. Its value is the product of
Detection Interval and Retry Times. For example, by default, its value is 3000 (1000
× 3 = 3000) milliseconds.
For a normal Internet connection and a faulty Internet connection, the detection
