Apparatus and method for application-aware network traffic management
A computer-implemented method for controlling data traffic in a network system is disclosed. The method includes establishing a list of prioritized applications on a user device. The applications are monitored for network activity. One or more management packets are assembled in response to detecting network activity corresponding to one of the prioritized applications. The one or more management packets include network attribute information. The management packet is then transferred to a network switch for use in configuring the prioritization of data traffic on the network system.
