Abstract: A system capable of detecting data within user application streams to manage or control the chains. For example, the system can receive bandwidth information from the application, and based on that information, determine a level of network traffic caused by the application. Such bandwidth information can include any one or more of subscription information, information provided by an application running on a user device, information provided by an application function, and a detected application type. Based on the bandwidth information, the system can either determine a service chain route for the stream, or determine how to bill for the traffic caused by the application. For example, such determinations may be conducted dynamically based on previously determined if/then rules established by a user of the system.
