How To – Apply Bandwidth Restriction on a
Specific Website
Applicable Version: 10.00 onwards
Bandwidth is the amount of data passing through a media over a period of time and is measured in
terms of kilo Bytes per second (KBps) or Kilo bits per second (Kbps).
Quality of Service (QoS) is a method to guarantee a bandwidth relationship between individual
applications or protocols. It is a traffic-management approach that allows you to apportion network
resources for both mission-critical and normal data, based on the type of network traffic and the
priority you assign to that traffic.
The primary objective of QoS policy is to manage and distribute total bandwidth on certain parameters
like user, firewall, web category or application. QoS policy allocates & limits the maximum bandwidth
usage of the user and controls web and network traffic.
Policy can be defined/created for:
User - It restricts the bandwidth of a particular user.
Firewall Rule - It restricts the bandwidth for any entity to which the firewall rule is applied.
Web Category – It restricts the bandwidth for the URL categorized under the Web category.
To implement restriction, policy is to be assigned through firewall rule.
Application – It restricts the bandwidth for the application. To implement restriction, policy is
to be assigned through firewall rule.
