Flow attributes

Additional AA classification

Flow attributes allow for further classification of flows, other than according to application or application group. Flow attributes can be marked against packets of a flow.

Attributes are assigned to a flow based on characteristics of the flow. A flow may have zero or more attributes assigned to it including competing or conflicting attribute values such as Video and Video ABR.

Flow attributes can be based on the following:

• application filter provisioned: the flow attribute is based on the application filter definition

• flow state derived: the flow attribute is derived by an algorithm based on the protocol in use

Including flow attributes in an AQP allows match criteria and actions based on flow attribute, for example, application of a bandwidth policer or usage-based billing. To include flow attributes in an AQP, flow attribute matching must be enabled in the ISA-AA Group.
