outgoing speed of 1000 kbps. You configure policy A for server A’s traffic and
policy B for server B’s traffic.
Figure 269 Bandwidth Management Behavior
Configured Rate Effect
In the following table the configured rates total less than the available bandwidth
and maximize bandwidth usage is disabled, both servers get their configured rate.
Priority Effect
Here the configured rates total more than the available bandwidth. Because server
A has higher priority, it gets up to it’s configured rate (800 kbps), leaving only 200
kbps for server B.
Maximize Bandwidth Usage Effect
With maximize bandwidth usage enabled, after each server gets its configured
rate, the rest of the available bandwidth is divided equally between the two. So
server A gets its configured rate of 300 kbps and server B gets its configured rate
of 200 kbps. Then the ZyWALL divides the remaining bandwidth (1000 - 500 =
500) equally between the two (500 / 2 = 250 kbps for each). The priority has no
effect on how much of the unused bandwidth each server gets.
