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; associating application-identifying information with the packet; forwarding the packet including the application-identifying information towards the destination node; and performing application-specific processing at a downstream device on at least one packet belonging to the active flow, the downstream device identifying the application associated with the active flow by extracting the application-identifying information from the packet.
