摘　　要：为加快推进铁路12306互联网售票系统(简称:12306)的IPv6改造,通过对12306用户访问流程的调研及12306 IPv6演进改造的难点分析,设计了12306 IPv6演进改造的初级阶段方案。结合实际情况,研究了基于双栈架构支持用户使用IPv6地址访问的改造方法,覆盖了域名解析、流量分发及应用服务改造的全流程,以最小的改造成本实现支持用户使用IPv6地址访问12306的目标,取得了较好的应用效果。In order to speed up the IPv6 transformation of the railway 12306 Internet ticketing and reservation system(12306 for short),this paper designed the primary phase scheme of the 12306 IPv6 evolution transformation through the investigation of the user access process of 12306 and the analysis of the difficulties in the 12306 IPv6 evolution transformation.Based on the actual situation,the paper studied a transformation method that supported users to access using IPv6 addresses based on a dual stack architecture.This method covered the entire process of domain name resolution,traffic distribution,and application service transformation.It implemented the goal of supporting users to access 12306 using IPv6 addresses with minimal transformation costs,and achieved good application results.
