| 摘 要： | 针对异步传输模式网络，提出了流量监测指标。基于C-5网络处理器，设计并实现了ATM网络流量监测分析系统。该系统能够执行ATM网络的VPI/VCI利用率测量、信元重组及上层协议分析等功能。实验数据表明，系统在监测OC-3/OC-12链路时丢包率小于0.001%，满足速率及精度的要求，能够实现线速测量。

| Abstract: | This paper proposes a set of traffic metrics of ATM network.A traffic measurement and analysis system is developed based on C-5 network processor.The system can perform VPI/VCI utilization measurement,real-time reassembly of data received over ATM network and higher level protocol analysis.Experiments with operated network and instrument show that the system can parse traffic at OC-12 with the cell loss rate less than 0.001%. |
