Erlang B Peaked(Neal-Wilkinson)   

The Neal-Wilkinson model is used to size overflow or alternate route trunk groups that receive peaked or bursty traffic from other high usage trunk groups such as inter-office backup paths. This model is useful when dealing with abnormally high traffic during occurrences such as holidays (Motherís Day) or disasters such as a stock market crash. The model uses the Erlang B formula but traffic is estimated using the equivalent random theory and peakedness factors.
Here's an example of the Neal-Wilkinson Peaked Traffic Model:
You need to input 2 items: 1.) Desired blocking probablility and 2.) Overflow Traffic Samples.  TrafficFinder! calculates the Peakedness Factor, Variance and Average Overflow Traffic.
