摘要
分析了目前交通信息网的状况,分析弹性分组环(RPR)技术的MAC机制、空间重用传输机制、50ms保护倒换时、自动拓扑发现等特点及优势,提出了利用RPR来组建多业务宽带智能交通通信网络平台。
This paper primarily analyzed the condition of current transportation system. After analyzingthe traits and advantages of its media access control (MAC) layer standard, bandwidth multiplication withdynamic and fair bandwidth allocation on a ring, capable of sub 50 ms switching etc., the RPR technologyis put forward to suits to be used establish information platform of ITS.
