<p><P>PROBLEM TO BE SOLVED: To provide a forwarding apparatus or the like in a system supporting PPP multi-link, copying/deleting only meta data information in a packet stored in a buffer of a memory, and performing packet fragmentation for multi-linking and packet copying for multicast traffic processing in the PPP multi-link, to thereby improve performance of a forwarding engine. <P>SOLUTION: The apparatus includes: a memory (100) adapted to store a received frame and a buffer handler having meta data information; and a network processor (200) adapted to store the frame received from an external network interface card in the memory, store the buffer handler indicating the frame and as many buffer handlers as either frame copies for multicasting or fragments for multi-linking, check the buffer handler stored in the memory and then to copy and transmit the corresponding frame stored in the memory via a corresponding port upon transmitting the frame to the card, and delete corresponding buffer handlers after transmitting the frame to the external network interface card, thereby managing forwarding of the frame. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
