摘要:
对比分析了青岛地铁4号线与2号线的DCS(数据通信系统)网络架构特点。青岛地铁4号线的DCS网络架构是在青岛地铁2号线的基础上演化而来的。为满足安全性要求,青岛地铁4号线DCS网络架构继承了青岛地铁2号线的优点,并对网络架构进行了进一步优化;采用A/B网设计思路,对不同类型业务进行物理隔离,增强了整个网络的冗余度和可靠性。
Abstracts:
The features of network architecture of the DCS (Data Communication Subsystem) of Qingdao Metro Line 4 and Line 2 are analyzed and compared. The network architecture of Qingdao Metro Line 4 evolved from Qingdao Metro Line 2. In order to meet the safety requirements, the network architecture of Qingdao Metro Line 4 inherits the advantages of Qingdao Metro Line 2 and is further optimized, using A/B network design ideas and physical isolation of different types of services to enhance the redundancy and reliability of the entire network.
