【摘要】 当前我国的城市化工程建设发展进程加快,城市轨道交通网络建设发展迅速。为了与城市社会生活紧密融合,列车通信网络不断提高其开放性与网络互联性,但无法保证其网络安全性。采用OPNET网络仿真软件对具备车地通信功能的以太列车通信网络进行网络层模型、节点层模型和进程层模型的搭建,为了测试其网络安全性,对该模型进行了一次网络攻击仿真。仿真结果表明,该模型具备网络防御能力,能够保障列车通信网络的安全性。更多还原

【Abstract】 At present, China’s urbanization project construction is accelerating, and the urban rail transit networks is developing rapidly. In order to deeply integrate with urban social life, the train communication network has continuously improved its openness and interconnection, but its network security cannot be guaranteed. Through the use of OPNET network simulation software, the network layer model, node layer model and process layer model of the Ethernet train communication network with vehicle-ground communication function are constructed. In order to test its network security, a network attack simulation is performed on the model. The simulation results indicate that the model has network defense capabilities and can guarantee the security of the train communication network.更多还原
