摘要
相比于核心层的网状结构以及路由协议的支持,数据网接入层的故障对业务的影响更大。简要介绍铁路数据网发展及现网结构,探讨常用的业务接入方式以及安全接入应采取的保障措施。
Compared with the network structure of the core layer and the support of the routing protocol, the faults of the data network access layer are more likely to cause traffic disruption. We briefly introduce the development of railway Data Communication Network, or DCN, and its network structure and further discuss the common scheme of service access and the secure access measures to be taken.
