【摘要】 针对地铁信号仿真系统对通信的实时、多方、可扩展的要求,建立一个基于P2P通信技术的实时通信平台。平台以点对点方式广播信息,同时利用反射机制进行控制命令的解析和执行,减少与应用层的耦合度。给出一个新的应用层广播算法,该算法能在能在广播网中寻找到最佳的传送路径,同时保证在网络拓扑改变时传送路径能平滑过度。更多还原

【Abstract】 A real-time communication platform for Metro Signal Simulation System(MSSS) is presented.MSSS requires a real-time,multi-party and scalable communication.In our research,a broadcast network was constructed in peer to peer mode.And Reflection was used in the process of analysing and executing controlling messages for reducing the coupling with the application layer.Finally,a new broadcast algorithm is presented,which can find a best path for message sending and guarantee a smooth path switching when the network topology changes.更多还原
