Embodiment 1
[0075] The first preferred implementation mode of the above-mentioned embodiment of the present invention specifically includes the following steps:
[0076] (1) MN establishes a tunnel
[0077] In order to switch the data packet corresponding to the UDP service flow with the destination port number 1234 to eth0 for transmission, the MN establishes an IPv6tn1 tunnel from eth0 to HA, specifically:
[0078] The MN uses the Linux built-in extensible function framework XFRM to generate the XFRM policy (policy) corresponding to the IPv6tn1 tunnel, and uses the XFRM policy to match the data packet corresponding to the UDP service flow entering the IPv6tn1 tunnel with the destination port number of 1234. In the XFRM policy The XFRM template (template) saves the information of the IPv6 header that encapsulates the matched data packet. The source address of the IPv6 header is the entry address of the IPv6tn1 tunnel, that is, the care-of address CoAv6 of eth0, and the destination addres...
