  • System and method for low-complexity, high-speed preprocessing of encapsulated packets in a broadband communications network
    Patent number: 9236936
    Abstract: Systems and methods for performing preprocessing of received data packets, to reduce processing burdens and improve efficiency of communications terminal receivers, are provided. A first stage filter receives a data frame comprising data packets representing respective encapsulated fragments of a PDU. The first stage filter parses a header of one of the packets to locate a start field, and determines whether the start field indicates that the packet comprises a start fragment of the PDU. When the start field indicates that the packet comprises the start fragment, the first stage filter determines, based on packet label information of the packet header, whether to forward the packet to a second stage filter or to discard the packet, and forwards or discards the packet accordingly. When the start field indicates that the packet does not comprise the start fragment, the first stage filter forwards the packet to the second stage filter.
