摘　　要：针对航空电子全双工交换式以太网交换节点流量管制功能,采用信用量消耗边界探测机制实现流量管制功能测试,提出了数据帧转发模型、数据帧边界转发模型、数据帧管制模型和数据帧边界管制模型等4种流量管制测试模型,从微观角度观测交换节点对"违规"流量管制处理的结果。开发了流量管制功能测试系统,验证了流量管制模型边界探测机制的正确定和有效性,克服了基于数据帧输入和输出计数统计的宏观测试精确性不足的问题。与理论处理结果进行了对比,结果表明,该系统能够很好地实现交换节点流量管制功能的测试和评估。Aiming at the function of traffic policing in the switch node of avionics Full DupleX switched ethernet, boundary detecting mechanism based on credit consumption to test the function of traffic policing is proposed. Four models of traffic policing are proposed as the data frame transmitting model, data frame boundary transmitting, data frame policing model and the data frame border policing to observe the results of ＂illegal＂ traffic policing of switch nodes from the microcosmic view. Testing system for the function of traffic policing is developed. The feasibility and effectiveness of the boundary detecting mechanism for models of traffic policing is validated. It overcomes the problem of insufficient accuracy of the macro testing by the input and output data frames based on counting statistics. By comparing the results with the theoretical results, it can achieve testing and.evaluating of traffic policing function of the switch node.
