摘要
随着高速铁路综合视频监控、会议电视、办公管理信息系统等新兴数据通信业务的快速发展,并逐渐取代传统的语音业务成为高速铁路通信的主流,如何组建高速铁路数据网成为亟待解决的问题。本文在对兰渝线数据通信网承载的各种业务的网络拓扑结构和带宽需求进行分析的基础上,围绕数据网组网技术和网络结构的选择、网络节点和数据设备的选定、带宽分配等几个方面进行了讨论,并结合兰渝线线路情况异常复杂的特点提出了一个安全可靠、经济合理的数据网组网方案。
The data telecommunication services such as integrated video frequency monitoring, video conference, office managed information system, etc. are rapidly developed, and its replacing gradually conventional voice service will become the mainstream of communications for high speed railway. How to set up the data network for high speed railway is the most important issue which needs to be solved urgently. This paper analyzes the network topology and bandwidth demands for all services of data communication network of Lan-Yu railway, discusses something about how to select the data networking technology and network configuration, network node and data equipment and bandwidth allocation and combined with features of very complex route condition of Lan-Yu railway, presents a safe, reliable and reasonable data networking scheme.
