| Abstract: |
| [Objective] A smooth evolution scheme is designed for Guangxi E-government extranet transitioning from IPv4(Internet Protocol version 4) network to IPv6(Internet Protocol version 6) network and guides the construction of IPv6 network platform of Guangxi E-government extranet.[Method] Based on the IPv4 network platform of Guangxi E-government extranet by using MPLS VPN(Multi-Protocol Label Switching Virtual Private Network) technology, along with the IPv4/IPv6 dual stack technology in IPv6 plane,the technology of 6PE (IPv6 Provider Edge) and 6VPE (IPv6 VPN Provider Edge) technology,the scheme achieves the access of IPv6 users before the construction of E-government extranet, and the smooth transition and upgrading from IPv4 networks to a pure IPv6 network gradually.[Result] The result shows the design of IPv6 network platform architecture and evolution path of Guangxi E-government extranet are completed, which finally achieves the construction of pure IPv6 network of E-government extranet.[Conclusion] The smooth evolution scheme designed in this paper provides a sustainable business transfer mode, which realizes the IPv6 supported by Guangxi E-government extranet network platform and gradually evolved into the IPv6 network. |
