Abstract: The traditional network management architecture of railway communication faces the challenges of low resource utilization rate, poor scalability and low reliability. In view of the actual situation of engineering design, this paper analyzes and compares two architecture of cloud infrastructure, and considers the existing resources of the bearer network system of a certain communication network management center of China Railway Guangzhou Group Co., Ltd., to propose a construction scheme for the network management cloud platform of the railway communication bearer network. The proposed scheme involves the fused application of cloud computing, virtualization technology and railway communication network management to enhance network management efficiency, reduce the cost of operation and maintenance and increase network flexibility.

Key words: communication, network management cloud, construction scheme

摘要： 传统的铁路通信网络管理架构面临着资源利用率低、扩展性差、可靠性低等挑战。结合工程设计实际，通过分析比较两种云基础设施架构，基于广州局某一通信网管中心既有承载网系统资源情况，提出铁路通信承载网建设网管云平台方案，实现云计算、虚拟化技术和铁路通信网络管理的融合应用，以提高网络管理效率、降低运维成本并增强网络的灵活性。
