  • Patent number: 8717942
    Abstract: The disclosure provides a method and a network device for packet content translation, wherein the network device comprises: a packet analyzing unit, a packet comparing unit, and a calculating unit, and the method comprises: providing a packet content translation criteria table; obtaining characteristic information of a packet; comparing the characteristic information of the packet with the packet content translation criteria table to determine whether a corresponding match entry is found in the packet content translation criteria table; and using the calculating unit to perform a packet content translation for the packet according to a packet processing mode indicated by the corresponding match entry. The method and the network device for packet content translation of the disclosure can reduce resource requirement for network equipments.

  • Publication number: 20120134360
    Abstract: A device for processing a network packet includes a capturing unit, a look-up table supplying unit, a preprocessing unit and a control unit. The capturing unit is utilized for capturing an information from the network packet. The look-up table supplying unit is utilized for supplying a look-up table. The preprocessing unit is coupled to the capturing unit and the look-up table supplying unit, for comparing the information with the look-up table to generate a comparison result. The control unit is coupled to the preprocessing unit, for choosing a processing rule to process the network packet according to the comparison result.
