bandwidth, and the FTP connection will receive 25% (10/40) of the leftover
bandwidth. If the Web connection closes, the FTP connection will receive 100% of
the bandwidth.
Each class has a bandwidth limit, which is the maximum amount of bandwidth that
connections belonging to that class may use together. Once a class has reached its
bandwidth limit, connections belonging to that class will not be allocated further
bandwidth, even if there is unused bandwidth available. For example, traffic used
by Peer-To-Peer file-sharing applications may be limited to a specific rate, such as
512 kilobit per second. Each class also has a “Delay Sensitivity” value, indicating
whether connections belonging to the class should be given precedence over
connections belonging to other classes.
Your Safe@Office appliance offers different degrees of traffic shaping, depending
on its model:
• Simplified Traffic Shaper. Includes a fixed set of four predefined classes.
You can assign network traffic to each class, but you cannot modify the
classes, delete them, or create new classes. Available in Safe@Office 500.
• Advanced Traffic Shaper. Includes a set of four predefined classes, but
enables you to modify the classes, delete them, and create new classes.
You can define up to eight classes, including weight, bandwidth limits, and
DiffServ (Differentiated Services) Packet Marking parameters. DiffServ
marks packets as belonging to a certain Quality of Service class. These
packets are then granted priority on the public network according to their
class. Available in Safe@Office 500 with Power Pack.
Note: You can prioritize wireless traffic from WMM-compliant multimedia
applications, by enabling Wireless Multimedia (WMM) for the WLAN network. See
Manually Configuring a WLAN on page 167.
