Bandwidth

Application layer BWM (bandwidth management) allows you to create a policy that regulates bandwidth consumption by specific file types within a protocol, while allowing other file types to use unlimited bandwidth. This enables you to distinguish between desirable and undesirable traffic within the same protocol. Application layer bandwidth management is supported for all Application matches, as well as custom Security Action Profiles configured on OBJECT | Action Profiles > Security Action Profile page using HTTP client, HTTP Server, Custom, and FTP file transfer types. For more information about Security Action Profiles, refer to Configuring a Bandwidth/QoS Security Action Profile.

Before configuring any BWM policies, make sure to configure the Bandwidth Management profile objects on the OBJECT | Profile Objects > Bandwidth page according to Configuring Bandwidth Profile Objects.

Application layer bandwidth management configuration is handled in the same way as Access Rule bandwidth management configuration. However, with Security Action Profiles you can specify all content type, which you cannot do with access rules.

For a bandwidth management use case, as an administrator you might want to limit .mp3 and executable file downloads during work hours to not more than 1 Mbps. At the same time, you want to allow downloads of productive file types such as .doc or .pdf up to the maximum available bandwidth, or even give the highest possible priority to downloads of the productive content. As another example, you might want to limit bandwidth for a certain type of peer-to-peer (P2P) traffic, but allow other types of P2P to use unlimited bandwidth. Application layer bandwidth management allows you to create policies to do this.

A number of BWM action options are also available in the default action list. The BWM action options change depending on the Bandwidth Management Type setting on the OBJECT | Profile Objects > Bandwidth page.

Guaranteed bandwidth for all levels of BWM combined must not exceed 100%.
