摘　　要：当前中国电信正处在大规模建设分组综合承载网(IP RAN)的初期,如何建立系统完整的规划方法、构建合理的网络架构,如何充分利用现有光缆资源、与现有接入光缆网协同、降低建网难度与成本,并避免SDH网络存在的单汇聚节点入局光缆同管道、单电源等安全问题,已成为IP RAN规划的重点。详细介绍了安徽电信在IP RAN专项规划实践中创立的"建模—筛选—分类—组网"四步法,并研究归纳了不同组网架构下与ODN协同场景,为大规模建设IP RAN提供了一套系统完整的规划方法。China Telecom is in early days of large-scale constructing group IP RAN, how to build a complete planning method, build reasonable network architecture, how to make full use of the existing cable resources, with access to the existing fiber-optic, decrease the difficulty and cost reduction, and to avoid single convergence of SDH network such as the incoming cable with pipe, single node power supply security problems, has become the focus of IPRAN network planning. It introduces Anhui Telecom＇s IP RAN network special planning practice of four steps method （modeling, screening, classification, networking）, and sums up the research under different network architecture with ODN cable collaborative scene, RAN for large-scale construction of IP network offers a complete set of system planning method.
