Abstract:
Statistical methods are used to observe packet flow arrival processes and to infer routing changes from those observations. Packet flow arrivals are monitored using NetFlow or another packet flow monitoring arrangement. Packet flow arrivals are quantified by counting arrivals per unit time, or by measuring an inter-arrival time between flows. When a change in packet flow arrivals is determined to be statistically significant, a change in network routing protocol is reported.
