CHAPTER 17
Bandwidth Management
Bandwidth Management (BWM) enables Web site managers to allocate a certain portion of the
available bandwidth for specific users or applications. It allows companies to guarantee that
critical business traffic, such as e-commerce transactions, receive higher priority versus non-
critical traffic. Traffic classification can be based on user or application information. BWM
policies can be configured to set lower and upper bounds on the bandwidth allocation.
