21.6.2 Bandwidth Borrowing Example
Here is an example of bandwidth management with classes configured for bandwidth
borrowing. The classes are set up based on departments and individuals within certain
departments.
Refer to the product specifications in the appendix to see how many class levels you can
configure on your ZyWALL.
• The Bill class can borrow unused bandwidth from the Sales USA class because the Bill
class has bandwidth borrowing enabled.
• The Bill class can also borrow unused bandwidth from the Sales class because the Sales
USA class also has bandwidth borrowing enabled.
• The Bill class cannot borrow unused bandwidth from the Root class because the Sales
class has bandwidth borrowing disabled.
• The Amy class cannot borrow unused bandwidth from the Sales USA class because the
Amy class has bandwidth borrowing disabled.
• The Research Software and Hardware classes can both borrow unused bandwidth from the
Research class because the Research Software and Hardware classes both have bandwidth
borrowing enabled.
