基于RPR的MSTP体系结构和MPLS VPN技术在电力城域网中的应用

RPR-based MSTP Architecture and MPLS VPN Technique Applied in Power Metropolitan Area Network

讨论电力城域网的构架和需求,分析电力城域网建设面临的压力,重点论述了基于弹性分组环(RPR)的多业务传送平台(MSTP)体系结构和多协议标签交换虚拟专用网络(MPLS VPN)技术,两者相结合的组网方案在电力城域网中的应用具有无可比拟的优势,是向未来智能光网络演进的可行方案。

This paper discusses the framework and demand of power metropolitan area network（MAN）, analyzes the pressure on the construction of power MAN, and detailedly describes the multi-service transport platform（ MSTP） architecture based on resilient packet ring（ RPR）as well as the technique of multiprotocol label switching virtual private network（MPLS VPN） The networking scheme which combines the two has unparalleled advantages when applied in power MAN, and is a feasible plan for the evolution toward intelligent optical network in the future,
