Abstract
A method for deep-packet inspection of packets flowing through an end unit in a point-to-multipoint network. The method comprises classifying packet flows through the end unit using their flow-identification (ID) to determine which of the packet flows should be deep-packet inspected, wherein the packet flows include incoming packets received from a central unit and outgoing packets sent to the central unit of the point-to-multipoint network; duplicating packets determined to be deep-packet inspected; saving all duplicated packets in a memory; upon collection of a predefined number of duplicated packets belonging to a certain flow-ID, performing deep-packet processing based on at least one deep-packet inspection application; and saving the deep-packet processing results in the memory.
