17.1 O ve rvie w
This chapter contains information about configuring bandwidth management and editing rules.
ZyXEL’s Bandwidth Management allows you to specify bandwidth management rules based on an
application.
In the figure below, uplink traffic goes from the LAN device (A ) to the WAN device (B). Bandwidth
management is applied before sending the packets out to the WAN. Downlink traffic comes back from
the WAN device (B) to the LAN device (A). Bandwidth management is applied before sending the
traffic out to LAN.
