随着坚强智能电网建设和发展,传统SDH/MSTP通信传输网平台已不能够满足SG-ERP、省-市-县视频会商、输变电设备状态在线监测、应急通信、智能配网等对信息通信业务的IP化和高带宽需求,为此,需寻求一种新通信组网技术,既能满足IP业务承载、IP业务带宽突发性、高带宽等要求,又能实现网络级的OAM、QoS等。根据山东省地市数据承载网设计规划,提出基于PTN MPLS-TP的电力通信传输网第二平面的设计方案,供电力行业从业者参考。 With the construction and development of a strong smart grid, the traditional SDH / MSTP communication transmission network platform can no longer meet the requirements of SG-ERP, province-city-county video consultation, on-line monitoring of power transmission and transformation equipment, emergency communications and intelligent distribution network Therefore, it is necessary to seek for a new communication networking technology that can not only meet the requirements of IP service bearer, sudden and high bandwidth of IP service bandwidth, but also achieve network-level OAM , QoS and so on. According to the design plan of data bearer network of prefectures and cities in Shandong Province, a design scheme of the second plane of power communication transmission network based on PTN MPLS-TP is put forward for the reference of power industry practitioners.
