User Manual Part 1

Overview
252 Check Point Safe@Office User Guide
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 desired wireless
network. See Manually Configuring a Wireless Network on page 280.
