Abstract:

There is the danger of IPv4 addresses exhaustion in China, but IPv6 customer premise network (CPN) is not constructed widely, and the applications based on IPv6 network are very few moreover. Although there are international influences, but the main factors are the lack of IPv6 demonstration applications with commercial value and the encouragement policies which push on the IPv6 CPN deployment. The further close cooperation and integration between the equipment manufacturers and carrier operators that provide IPv6 professional services and the industry that needs IPv6 applications are also absent. This paper briefly introduces the construction of safe, reliable and cost-effective IPv6 network, and gives some suggestions on accelerating IPv6 network deployment and developing IPv6 demonstration applications by comparing Japanese IPv6 network construction and IPv6 network applications on information network security. This paper can give some references on accelerating the construction of IPv6 network and enhancing network security, especially the IPv6 customer premise network.

Key words: IPv6, customer premise network, network security
