Peplink Balance Series

Algorithm

This setting specifies the behavior of the Peplink Balance for the custom rule.

One of the following values can be selected:

 Weighted Balance

 Persistence

 Enforced

 Priority

 Overflow

 Least Used (not applicable to Balance 20/30/30 LTE)

 Lowest Latency (not applicable to Balance 20/30/30 LTE)

The upcoming sections detail the listed algorithms.

Terminate Sessions

on Link Recovery

This setting specifies whether to terminate existing IP sessions on a less preferred WAN

connection in the event that a more preferred WAN connection is recovered. This setting is

applicable to theWeighted,Persistence, and Priority algorithms.

By default, this setting is disabled. In this case, existing IP sessions will not be terminated

or affected when any other WAN connection is recovered.When this setting is enabled,

existing IP sessions may be terminated when another WAN connection is recovered, such

that only the preferred healthy WAN connection(s) isused at any point in time.

14.2.1 Algorithm: Weighted Balance

This setting specifies the ratio of WAN connection usage to be applied on the specified IP protocol

andport. This setting 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

theWAN connection relative to the total weight.Use the sliders to change each WAN’s weight.

For 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, for security reasons, many e-banking and other secure

websitesterminate 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
