12.2.2 Algorithm: Persistence
The configuration of using Persistence for algorithm 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 during the 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 MAX 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 Pepwave MAX may communicate using multiple Internet IP addresses.
For example, a LAN client computer behind a Pepwave MAX with three WAN connections may
communicate on the Internet using three different IP addresses.
With the algorithm Persistence of Pepwave MAX, 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 with the other end using one IP address and eliminate the issues.
There are two modes for Persistence: By Source and By Destination.
The same WAN connection will be used for traffic matching the rule and originating
from the same machine regardless of its destination. This option will provide the
highest level of application compatibility.
The same WAN connection will be used for traffic matching the rule, originating
from the same machine, and going to the same destination. This option can better
distribute load to WAN connections when there are only a few client machines.
The default mode is By Source.
When there are multiple client requests, they can be distributed (persistently) to WAN connections with a
weight. If you choose Auto for Load Distribution, the weights will be automatically adjusted according to
each WAN’s Downstream Bandwidth which is specified in the WAN settings page (see Section 8
Configuration of WAN Interface(s)). If you choose Custom, you can customize the weight of each WAN
manually by using the sliders.
