摘　　要：为了不断提高信息网络服务质量和水平,保证山东电力集团公司网络安全稳定运行,山东电力集团公司研究了基于多协议标签交换(MPLS)的VPN、服务质量保障(QoS)、流量工程(TE)等技术,并且采用这些技术对所属的广域网进行了优化,使广域网运行更加安全、可靠,对数据、语音和视频等实时应用系统的支持能力有了较大提高。项目的研究和实施填补了山东电力广域网功能上的多项空白,为其他网省广域网的改造提供了有益参考。To continuously improve quality of service and level of information networks and ensure network operation security and stability, this paper studies MPLS-based VPN technology, QoS ensuring technology and traffic engineering （TE） technology, and optimizes the WAN by application of these key technologies. The practice shows that the operation of WAN is more secure and reliable, and the support to real-time applications, such as data, voice and video, obtains a great improvement. The project also fills gaps in the functionalities of WAN of Shandong Electric Power Group Corporation, and provides a useful reference for other power companies＇ WAN transformation.
