A network system and the method is described that splits media identification logic and media classification and/or general data session processing/management logic into separate controllers (e.g., between the local controllers and a service controller). By separating media identification logic and media classification logic (or general media processing/management logic), the system and method allows for greater flexibility and scalability in a network system employing a service controller. In particular, by allowing the local controllers to perform media identification and to construct a single packet that characterizes/describes a media session, the system avoids the need to transmit multiple data packets of a media session to the service controller for classification of the session. Accordingly, the system includes the flexibility a service controller provides while allowing for greater scalability by separating media identification logic and media classification respectively between a local controller and the service controller.
