Traffic Management enables you to set the maximum bandwidth available for different types of traffic, and to guarantee a minimum amount of bandwidth for specific traffic flows. Both the maximum bandwidth and guaranteed bandwidth apply only if the necessary bandwidth is available through the interface that handles the traffic.
Traffic Management configuration is very flexible, and enables you to control traffic by policy, application, traffic direction, and source IP address. For example, you can use Traffic Management Actions to:
Before you implement Traffic Management, you must know the available bandwidth, and decide how much bandwidth you want to guarantee or limit for different types of network traffic. For more information, see Get Started with Traffic Management.
In the Traffic Management settings, 1 Kbps is equal to 1024 bits per second.
The Traffic Management action type determines how the action is applied. There are three Traffic Management action types:
An All Policies action applies to the combined bandwidth of all policies that use it. If you create an All Policies Traffic Management Action to set a maximum bandwidth of 10 Mbps and apply it to an FTP and an HTTP policy, all connections handled by those policies share the 10Mbps bandwidth maximum.
A Per Policy action applies individually to each policy that uses it. If you create a Per Policy Traffic Management Action to set a maximum bandwidth of 10 Mbps and apply it to an FTP and an HTTP policy, connections handled by each of those policies can use a maximum of 10Mbps.
Per IP Address
A Per IP Address action applies individually to each source IP address for all policies that use the action. If you create a Per IP Address Traffic Management Action to set a maximum bandwidth of 10 Mbps and apply it to an FTP and an HTTP policy, the connections from each source IP address handled by those policies can use a maximum of 10 Mbps.
For a Per IP Address action, you set the Maximum Instance, which is the maximum number of source IP addresses that the action can apply to. If the number of source IP addresses exceeds the maximum instance, some source IP addresses begin to share the bandwidth settings in the action.
When the number of concurrent source IP addresses that use a Traffic Management Action exceeds the Maximum Instance for the action, a round-robin algorithm determines which source IP addresses share bandwidth. Recently connected source IP addresses share bandwidth with client IP addresses that have been connected longest. For example, if a Per IP Address action has a Maximum Instance of 10, the eleventh source IP address shares bandwidth with the first source IP address that used the action, the twelfth source IP address shares bandwidth with the second source IP address that used the action, and so on.
To configure a Traffic Management Action:
After you add a Traffic Management Action, you can apply it to policies and applications.
You can clone, edit, or remove an existing Traffic Management action
