为了更好地推荐轨道交通领域对传输网络的建设方案,构建健壮、多业务、弹性的传送平台,提出构建弹性可重购(3R:Reconfigurable,Resilient,Reliable)、高效性价比、统一的多业务传递平台的解决方案。对主流传输技术进行了详细比较,认为弹性可重购3R多业务传送平台满足轨道交通分拆和延长分期建设的要求。展望了未来的承载网技术,分析和比较了MSTP(多业务传送平台)和IP传送平台。
In order to better recommend the construction of transmission network in the field of rail transit and build a robust, multi-service and flexible delivery platform, a 3R (Reconfigurable, Resilient), Reliable, cost-effective and multi-service delivery Platform solutions. A detailed comparison of the mainstream transmission technologies shows that the flexible and reusable 3R multi-service delivery platform meets the requirements of rail transit splitting and extension staging. Looking forward to the future bearer network technology, analysis and comparison of MSTP (multi-service delivery platform) and IP delivery platform.
