How Bandwidth Management in ZyWALL?
ZyWALL achieves BWM by classifying packets, and control when to send out the classified packets.
Bandwidth Management of ZyXEL appliances operates on the IP layer. The major step to configure
BWM is defining filter rules by fields of IP header or TCP/UDP port number. Then specify the volume of
bandwidth you want to allocate to the filtered traffic. There are two types of BWM in ZyXEL
implementations, Full and Lite versions.
Full version: Users can define how they want to classify traffic on each interface. In this version,
child-class can borrow bandwidth from parent-class if necessary by Bandwidth Borrowing. For classes
that need more bandwidth even after bandwidth borrowing, users can also apply Maximize Bandwidth
Usage from the interface.
