Peplink Balance Series
14.2.1 Algorithm: Weighted Balance
This setting specifies the ratio of WAN connection usage to be applied on the specified IP Protocol & Port,
and is applicable only when Algorithm is set to Weighted Balance.
The amount of matching traffic that is distributed to a WAN connection is proportional to the weight of
WAN connection relative to the total weight. Use the sliders to change each WAN’s weight.
Example:With the following weight settings on a Peplink Balance 310:
• WAN1: 10
• WAN2: 10
• WAN3: 5
Total weight is 25 = (10 + 10 + 5)
Matching traffic distributed to WAN1 is 40% = (10 / 25) x 100%
Matching traffic distributed to WAN2 is 40% = (10 / 25) x 100%
Matching traffic distributed to WAN3 is 20% = (5 / 25) x 100%
14.2.2 Algorithm: Persistence
The configuration of Persistent Services is the solution to the few situations where link load distribution for
Internet services is undesirable.
For example, many e-banking and other secure websites, for security reasons, terminate the session
when the client computer’s Internet IP address changes mid-session.
In general, different Internet IP addresses represent different computers. The security concern is that an
IP address change during a session may be the result of an unauthorized intrusion attempt. Therefore, to
prevent damages from the potential intrusion, the session is terminated upon the detection of an IP
address change.
Peplink Balance can be configured to distribute data traffic across multiple WAN connections. Also, the
Internet IP depends on the WAN connections over which communication actually takes place. As a result,
a LAN client computer behind Peplink Balance may communicate using multiple Internet IP addresses.
For example, a LAN client computer behind a Peplink Balance 310 with three WAN connections may
communicate on the Internet using three different IP addresses.
With the Persistency feature of PeplinkBalance, rules can be configured to enable client computers to
persistently utilize the same WAN connections for e-banking and other secure websites. As a result, a
client computer will communicate using one IP address and eliminate the issues.
There are two Persistent Modes. One isby source and the other by destination.
