Abstract: |
The invention belongs to network interconnection technology. Its characters show as follow: it combines two schemes of multipoint access technology of integrated tunnel broker and 6to4 tunnel. The dual stack hosts in the IPv4 network have global IPv6 addresses and 6to4 address simultaneously. While visiting the IPv6 network, it will use the global IPv6 addresses and tunnel mechanism, and 6to4 addresses and 6to4 tunnel mechanism will be used when another dual stack host in the IPv4 network carries out IPv6 communication. Thus, IPv6 protocol communication between two dual stack hosts in the IPv4 network will not pass the relay gateway, the relay Gateway pressure is alleviated effectively and the user experience is improved, and the pure IPv6 network visiting by the dual stack host in the IPv4 network also avoids the problems which 6to4 address is difficult as routing aggregation. The method learns form other's strong points to offset ones' weaknesses, and forms a better application method of using the host in the IPv4 network. |
