摘要
铁路信息网络作为铁路信息系统的基础环境和重要组成部分,应采用先行部署的IPv6演进策略。通过对铁路信息网络现状进行调研,可得出各个网络区域现有的设施设备和软件应用的IPv6支持度良好,这为IPv6演进升级提供了有利条件。分别制定了互联网访问场景、内部访问场景和云环境访问场景下,以双栈技术为基础的IPv6综合演进方案,能够实现3个典型场景下端到端访问的IPv6化,这也为铁路信息系统实现全面IPv6化的目标奠定了有力的基础。
As the basic environment and important component of railway information system,railway information network should adopt the IPv6 evolution policy of advance deployment. By investigating the current situation of railway information network, it can be concluded that the existing facilities and software applications in each network zone have good IPv6 support, which provides favorable conditions for IPv6 evolution and upgrade. Under the Internet access scenario,internal access scenario and cloud environment access scenario, the comprehensive IPv6 evolution scheme based on the dual stack technology can realize end-to-end IPv6 access under the three typical scenarios, which also lays a strong foundation to achieve the goal of adopting IPv6 in all railway information systems.
