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.

Tip

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.
