摘要
随着语音、视频和数据业务的大量增加,轨道交通通信传输网络的主要业务逐渐由传统的TDM(时分复用)业务向宽带以太网数据业务转变。通过对主流技术和新技术的分析,探讨了轨道交通传输网络的发展趋势和新技术在轨道交通传输网络应用的前景。
With the rapid development of IP-based services in voice, video and other data services, the main business of urban rail transit communication network has trans- formed gradually from traditional time division multiple- xing （TDM） service to Ethernet data service. Through an analysis of the mainstream and new technologies in this field, the development trend of urban rail transit communi- cation network and the application prospect of new tech- nologies in rail transit are discussed.
