Seamless converging system for IPv4/IPv6 transition

摘要

The IPv4 address pool of ICANN has been depleted. Internet service providers are accelerating the research and deployment of IPv6 transition solution. Dual stack and tunneling technologies can only allow IPv4 and IPv6 to coexist, but can't make IPv4 and IPv6 network interact with each other. For alleviating the shortage of IPv4 address, accelerating the deployment of IPv6 and promoting the seamless converging of IPv4 and IPv6 network, this paper illustrate the design and implementation of an IPv4/IPv6 seamless converging system. The system is mainly composed by stateful and stateless protocol translation modules and can make hosts with shared IPv4 address or global IPv6 address access IPv4 Internet across IPv6 backbone.
