Problems solved by technology

[0003] However, since the basic structure of the IPv4 network is quite complete, there are currently a large number of IPv4 users and devices in the Internet network, and it is impossible for communication network operators to abandon the existing IPv4 network and rebuild the IPv6 network. Therefore, the direct transition from IPv4 protocol to IPv6 protocol is not realistic

Embodiment Construction

[0011] see figure 1 , shows the application environment and structure diagram of the router 10 in the embodiment of the present invention. In this embodiment, the router 10 handles the IPv4 and IPv6 communication between the LAN and the WAN. If it is the IPv4 and IPv6 communication in the LAN, the data packet transmission can be completed through a hardware gateway and a software bridge. The router 10 includes a LAN port 110 and a WAN port 120 . The router 10 is connected to the LAN 20 and the WAN 30 through the LAN port 110 and the WAN port 120 respectively, for receiving and processing data packets from the LAN 20 and the WAN 30 .

[0012] In this embodiment, the router 10 includes a packet judgment module 130 , a network judgment module 140 , a modification module 150 , a packet forwarding module 160 and a processing module 170 . The packet judging module 130 is used for receiving a data packet from the LAN 20 or the WAN 30 through the LAN port 110 or the WAN port 120, an...

Abstract

The invention discloses a method for processing an IPv6 packet by a router, comprising the following steps: receiving a packet, judging whether the pocket is the IPv6 pocket; if so, judging the source of the IPv6 packet according to the control information of the IPv6 packet; modifying the control information of the IPv6 packet according to the source of the IPv6 packet; and directly forwarding the IPv6 packet to a local area network or a wide area network according to the modified IPv6 packet control information. The invention also provides a router for processing the IPv6 packet; the routerand the method for processing the IPv6 packet thereof can simultaneously process an IPv4 packet and the IPv6 packet under the condition that the original network architecture is basically not changed.

Description

technical field [0001] The invention relates to a network device, in particular to a router and a method for processing IPv6 data packets. Background technique [0002] In the traditional IP network, the IPv4 network communication protocol is mainly used. With the continuous development of the Internet, the IPv4 network communication protocol has gradually exposed many deficiencies, among which the most serious and urgent need to be solved is the problem of IP address space exhaustion and the routing table of the backbone router being too large, these two problems directly lead to The birth of the next-generation Internet protocol, the IPv6 network communication protocol. [0003] However, since the basic structure of the IPv4 network is quite complete, there are currently a large number of IPv4 users and devices in the Internet network, and it is impossible for communication network operators to abandon the existing IPv4 network and rebuild the IPv6 network. Therefore, the...
