Abstract
Various exemplary embodiments are a method and related device and computer-readable medium including one or more of the following: receiving a packet sent from the source node to the destination node; associating the packet with an active flow by accessing information in the packet; performing deep packet inspection (DPI) to identify an application associated with the active flow; determining a classification for the packet based on characteristics of the identified application; associating, with the packet, information identifying the classification; forwarding the packet including the information identifying the classification towards the destination node; and performing processing on the packet at a downstream device by extracting the classification from the packet.
