国家电网IMS承载网网络架构设计方案及带宽测算方法

摘要

深入研究和对比分析了国家电网IMS承载网的网络架构设计方案,包括骨干侧网络架构设计方案和过渡期网络架构设计方案,并依据网络架构、媒体流和信令流走向提出了IMS交换网对数据通信网骨干侧、接入侧的带宽需求和测算方法,对国家电网建设IMS承载网具有指导意义.%The design of network architecture for IMS bearer network of State Grid was studied and analyzed,including the backbone of the network architecture and transition network architecture.And according to the network architecture,media flow and signaling flow,the IMS switching network on the data communication network backbone side,access side of the bandwidth requirements and measurement methods were put forward,which have a guiding significance for the construction of IMS bearer network of State Grid.
