Abstract
Stateful inspection and classification of packets is disclosed. For a first packet associated with a network traffic flow, a differentiated services header value (DSHV) is determined to associate with the first packet. The DSHV is used to perform a lookup of a quality of service treatment associated with the DSHV. The treatment is applied to the first packet. A determination is made, for a second packet associated with the network traffic flow, to associate a second DSHV with the second, where the second DSHV is different from the first DSHV.
