APPARATUS AND A METHOD FOR PROCESSING DATA IN FORWARDING A PACKET OF A NETWORK DEVICE, CONCERNED WITH QUICKLY FORWARDING A PACKET BY REDUCING THE AMOUT OF COPYING OF DATA

摘要

PURPOSE: An apparatus and a method for processing data in forwarding a packet of a network device are provided to quickly forward a packet by reducing the amount of copying of data. CONSTITUTION: Each receiving buffer indicator(110) indicates the next receiving buffer indicator, and the last receiving buffer indicator indicates the first receiving buffer indicator. A transmission buffer indicator(120) operates in the similar manner as the receiving buffer indicator(110), and includes a socket buffer pointer part for indicating a start address of a relevant socket buffer(300). A controller(100) includes multiple transmission buffer indicators(120). A shared buffer indicator(130) includes a data pointer part for indicating a start address of a shared buffer(200) and a status indicator for indicating whether an empty shared buffer can be allocated to a transmission and reception buffer. Each shared buffer indicator(130) includes the next buffer indicator for indicating the next transmission buffer indicator. A socket buffer indicator(140) includes a data pointer part for storing a start address of a memory storing received data or data to be transmitted, and a temporary data pointer part.
