Abstract:
1. A method for analyzing network traffic using an improved Markov Modulated Poisson Process (‘MMPP’) Model with two barrier states, the method comprising: retrieving a previous state for the network traffic; measuring inter-arrival times between individual packets received in one or more network adapters; establishing a transition window [λ retrieving a previous fence value that prevents premature transitions into the idle state or the bursty state; and determining a current state for the network traffic in dependence upon the previous state for the network traffic, an inter-arrival time of a most recently received packet, the transition values, and the previous fence value; wherein the barrier states comprise a bursty barrier state and an idle barrier state, the bursty barrier state representing a potential transition from the bursty state to the idle state, the idle barrier state representing a potential transition from the idle state to the bursty state.
