Abstract:
1. A method to determine data-transmission congestion, the method comprising: generating an ordered series of bits, the ordered series of bits representing a history of communication receipts and communication failures between two network devices; splitting the ordered series of bits into a first portion of ordered series of bits and a second portion of ordered series of bits, wherein the first portion of ordered series of bits corresponds to earlier communication receipts and communication failures, and wherein the second portion of ordered series of bits corresponds to later communication receipts and communication failures that occur after the first portion of ordered series of bits; determining a first number that corresponds to a number of communication receipts and a number of communication failures during the first portion of ordered series of bits; determining a second number that corresponds to a number of communication receipts and a number of communication failures during the second portion of ordered series of bits; defining a null hypothesis that the difference between the first number and the second number is not statistically significant; determining an amount of data-transmission congestion using the entire ordered series of bits when the null hypothesis is true; and determining the amount of data-transmission congestion using the second portion of ordered series of bits when the null hypothesis is false.
