摘要
针对CTCS-3级列控系统中的信号安全数据网,对基层环网、子网间、网管系统等各组成部分分别做了可靠性分析,并着重从组网结构、光传输特性、交换机软硬件性能、过载处理、链路聚合、VRRP冗余、网管服务及环境适应性等方面,以系统的高度提出了综合可靠性指标。
Aiming at the signal safety data network of CTCS-3 train control system, the reliability analysis of basic loop network, connection between sub-networks and network management system is provided respectively. And integrative reliability indexes are also put forward from such aspects as network infrastructure, fiber transfer characteristic, switch performance, overload management, link aggregation, VRRP redundancy, network administration service and environment adaptability.
