Load Balance Algorithm Round Robin – Based on packet base, both tunnels will send
the packet alternatively. Such method can reach the balance of
packet transmission with fixed rate.
Weighted Round Robin –Such method can reach the balance
of packet transmission with flexible rate. It can be divided into
Auto Weighted and According to Speed Ratio.
Auto
Weighted can detect the device speed (10Mbps/100Mbps)
and switch with fixed value ratio (3:7) for packet transmission.
If the transmission rate for packets on both sides of the tunnels
is the same, the value of Auto Wighted should be 5.5.
According to Speed Ratio allows user to adjust suitable rate
manually. There are 100 groups of rate ratio for
Member1:Member2 (range from 1:99 to 99:1).
Fastest – Based on available bandwidth that integrated and
considered by DrayOS system, the system can adjust
dynamically for bandwidth of both VPN tunnels. In most
cases, VPN Tunnel with high rate will use the WAN interface
which has more available bandwidth.
