Patent ID: 7990971

Claim:
A packet processing apparatus comprising: a receiver converting an input packet to a packet having an internal data bus size and generating a data control signal; a packet pre-processing unit analyzing the input packet transferred from the receiver to generate basic delivery headers and performing a second layer associated process; a protocol translation unit processing the input packet according to a type of the input packet and the protocol translation unit including modules of protocol engines for inserting and removing necessary engines; a header processing unit removing a transitional header TH in the generated delivery header and inserting a PPP (point-to-point protocol) header in the input packet; a transmitter converting the input packet and the control signal and transmitting a converted packet and a converted control signal; a statistic information processing unit processing statistic information associated with the processing of the input packet; an LED (a light-emitting diode) driver collecting state information and transferring the collected state information to an external side; a microprocessor interface interfacing with an external CPU (central processing unit); an external commercial NSE (network search engine) interface transferring key values extracted by the protocol translation unit to an external commercial NSE and transferring a lookup result obtained by the external commercial NSE to the protocol translation unit; and a CPU interface unit controlling an external commercial MAC (media access control) chip.
