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%.
