Drag and drop to specify the order of WAN connections to be used for routing traffic. Only the

highest priority healthy connection that is not in full load will be used.

15.2.6 Algorithm: Least Used

The traffic matching this rule will be routed through the healthy WAN connection that is

selected in Connection and has the most available download bandwidth. The available

download bandwidth of a WAN connection is calculated from the total download bandwidth

specified on the WAN settings page and the current download usage. The available

bandwidth and WAN selection is determined every time an IP session is made.

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.

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
