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.
