Abstract
Stateful inspection and classification of packets is disclosed. For a first packet associated with a network traffic flow, a differentiated services header value is determined. The differentiated services header value is used to perform a lookup of a quality of service treatment associated with the differentiated services header value. The treatment is applied to the first packet. A return traffic packet is received. A differentiated services header value is written in the header of the return traffic packet.
