摘　　要：提出了基于覆盖网络的网络协议验证和在线仿真的仿真平台设计思想,通过统一的数据格式、管理策略定义和定制虚拟覆盖路由器节点的管理和控制中继等功能,建立基于覆盖网络的仿真系统.按照用户需求,该仿真系统利用标准的管理协议SNMP消息来定制仿真环境,用于协议验证和在线仿真,或提供在实际网络运行的在线仿真.在该平台上验证了一个故障容忍的路由机制,证明了在小规模的网络环境中该仿真系统的正确性和实用性.The design idea, in which a network simulation platform was built, online simulation carried out, according to network protocol was proposed. By means of the unified data structure, the definition of management policy and the customization of managing the virtual overlay routing nodes and controlling relay in transmission, the simulation system based on overlay network were established. According to the users＇ requirements, the simulation system can set up the simulation environment by using SNMP messages and verify the protocol function and online simulation or online simulation in network operation. A transient fault-resilient routing mechanism was tested on the platform, proving the correctness of the simulation system and its practicability in small-scale network environment.
