Abstract: Provided is a hierarchical packet processing apparatus and method. In one general aspect, a packet is analyzed, divided into an upper layer and a lower layer. It is determined whether a property of the packet to be analyzed has been already analyzed or has to be re-analyzed with respect to each of the upper and lower layers of the packet. Therefore, deep packet inspection is performed only when it is required, and thus assurance of quality of service (QoS) during packet processing can be achieved, as well as reduced waste of resources.
