15.2.7 Algorithm: Lowest Latency
The traffic matching this rule will be routed through the healthy WAN connection that is
selected in Connection and has the lowest latency. Latency checking packets are issued
periodically to a nearby router of each WAN connection to determine its latency value. The
latency of a WAN is the packet round trip time of the WAN connection. Additional network
usage may be incurred as a result.
The roundtrip time of a 6M down/640k uplink can be higher than that of a 2M down/2M up link because the overall
round trip time is lengthened by its slower upload bandwidth, despite its higher downlink speed. Therefore, this
algorithm is good for two scenarios:
● All WAN connections are symmetric; or
● A latency sensitive application must be routed through the lowest latency WAN, regardless of the WAN’s
available bandwidth.
15.2.8 Expert Mode
Expert Mode is available on some Pepwave routers for use by
advanced users. To enable the feature, click on the help icon and click
turn on Expert Mode.
In Expert Mode, a new special rule, SpeedFusion
TM
Routes, is
displayed in the Custom Rules table. This rule represents all
SpeedFusion
TM
routes learned from remote VPN peers. By default, this
bar is on the top of all custom rules. This position means that traffic for
remote VPN subnets will be routed to the corresponding VPN peer. You
can create custom Priority or Enforced rules and move them
above the bar to override the SpeedFusion
TM
routes.
Upon disabling Expert Mode, all rules above the bar will be removed.
