About Bandwidth Classes

Bandwidth classes identify the URL categories and cloud applications to which the service allocates bandwidth. You must configure the bandwidth classes before you can reference them in Bandwidth Control policy rules. To configure bandwidth classes, you can edit the predefined bandwidth classes or add new bandwidth classes, by grouping URL categories, applications, or domains into it. For example, if you want to control bandwidth for service updates, you could create a custom Bandwidth class including the URLs for the App Store and apply your desired policy. 

If you have created a custom bandwidth class that is not being used in any policies for a location, then the custom class will be added to the location’s default Bandwidth Control rule. The default rule includes all internet traffic not covered by other rules. By default, it is not guaranteed any bandwidth, but it can consume up to 100% of the bandwidth when available. These bandwidth settings can be changed by editing the default rule.

The Cloud Applications tab lists predefined bandwidth classes to which you can add domains. The predefined bandwidth classes cannot be deleted. You can also add your own custom domains.

Following are the predefined bandwidth classes:

  • File Share: You can enter URLs that represent file sharing sites.
  • Finance: You can enter URLs that represent business-oriented, financial web-based applications or tools, such as Smith Barney or eTrade.
  • General Surfing: This class includes all URL categories and cloud apps that do not fall into one of the following categories (Webmail, Instant Messaging, Streaming Media/File Share, and Social Networks/Blogging). This class cannot be edited.
  • Sales/Support Apps: You can enter URLs that represent business-oriented, sales/support web-based applications or tools, such as SalesForce or NetSuite.o
  • Streaming Media: You can enter URLs that represent streaming sites.
