  • DATA PACKET FORWARDING METHOD AND NETWORK DEVICE USING SUCH METHOD IN NETWORK ADDRESS TRANSLATION MODE
    Publication number: 20110211577
    Abstract: A data packet forwarding method and a network device using such a method in a network address translation mode are provided. The network device includes a central processing unit and a switch chip. The switch chip includes at least a wide area network port and plural local area network ports. The multicast packet is directly forwarded from said wide area network port to corresponding local area network ports. Since the central processing unit is not included in the forwarding path of the multicast packet, the speed of forwarding the multicast packet is enhanced.
