摘要
在IPv4地址耗竭,加快推进IPv6规模部署的关键时刻,运营商为保证平滑过渡,并兼顾后期纯IPv6的目标,采用IPv4/IPv6双栈的方案,同时实施IPv4地址的私网化改造,解决IP资源紧缺的问题,实现纯IPv6的全网部署。通过研究私网双栈的溯源模型,结合私网双栈溯源的电信类业务应用场景,以及溯源系统在传统固网AAA架构基础剥离后的云化改造,探索固网宽带私网双栈的地址溯源云化实现方法,为后续固网AAA整体云改提供参考。
As IPv4 address became exhausted even sooner,China Telecom had been speeding up the IPv4/IPv6 dual IP stack construction before the final large scale application of IPv6.Meanwhile,emphasis of IPv4 address privatize modification was placed on following schedule at this very moment to ensure the smooth transition and public IPv4 address providing.By studying the trace-back model of IPv6 and private IPv4 dual stack IP address in typical telecom business scenarios,the way to separate IP address trace-back model from traditional broadband AAA platform and migrated into cloud deployment were acquired,thus provided a reference for the AAA entirety reconstruction.
