RPR在电力城域信息网中的应用

Application of RPR in electric power metropolitan area network

随着电力企业信息化的推进,电力城域网(MAN)中传输的数据量将快速增长,基于弹性分组环(RPR)并结合了MPLS的MSTP能满足城域网对承载平台的要求。文章简要介绍了电力城域网承载的业务特点和要求,阐述了RPR和基于RPR结合了MPLS的MSTP协议栈,并结合实际工程应用,介绍RPR设备在电力城域信息网中实现TDM和数据业务的接入和传输特征,充分证实了基于RPR的MSTP平台可将RPR协议与MPLS协议无缝地结合在一起,具有跨环的端到端的严格QoS保障,是电力城域信息网的理想选择技术。

With the advance of power enterprise information, the date volume of the electric power Metropolitan Area Network（MAN） is quickly increasing, based on RPR and combined with MSTP can content the requirements of loaded platform on the MAN. The paper briefly introduces the services characteristics and requirement of the electric power MAN. The paper expounds RPR and RPR based MSTP protocol stack with MPLS. According to the applying in practice, the paper introduces the characteristics of RPR equipment, which can realize the access and transmitting of the TDM and data, and proves that MSTP will be a prefect technology in the electric power MAN.
