Abstract
In one embodiment, a data packet is received at a network device. A layer-2 identification (L2ID) value is identified for the received data packet based on a destination address and a label stack of the received data packet. The L2ID value is specific to an application associated with the data packet. A 6-tuple is created that includes the L2ID value. The received data packet is classified using the 6-tuple. Deep packet inspection (DPI) services are performed based on the classification of the received data packet. The DPI services apply a set of one or more application-level policies to the received data packet. The received data packet is forwarded from the network device toward a destination.
