Algorithm: Persistence - peplink Pepwave MAX Series User Manual

The amount of matching traffic that is distributed to a WAN connection is proportional to the weight of
the WAN connection relative to the total weight. Use the sliders to change each WAN's weight.
For example, with the following weight settings:
● Ethernet WAN1: 10
● Ethernet WAN2: 10
● Wi-Fi WAN: 10
● Cellular 1: 10
● Cellular 2: 10
● USB: 10
Total weight is 60 = (10 +10 + 10 + 10 + 10 + 10).
Matching traffic distributed to Ethernet WAN1 is 16.7% = (10 / 60 x 100%.
Matching traffic distributed to Ethernet WAN2 is 16.7% = (10 / 60) x 100%.
Matching traffic distributed to Wi-Fi WAN is 16.7% = (10 / 60) x 100%.
Matching traffic distributed to Cellular 1 is 16.7% = (10 / 60) x 100%.
Matching traffic distributed to Cellular 2 is 16.7% = (10 / 60) x 100%.
Matching traffic distributed to USB is 16.7% = (10 / 60) x 100%.

15.2.2 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
websites 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.
Pepwave routers 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 the Pepwave router may communicate using multiple Internet IP
addresses. For example, a LAN client computer behind a Pepwave router with three WAN connections
may communicate on the Internet using three different IP addresses.
