Method for detecting congestion in internet traffic

A method to detect congestion in a network traffic, comprising:

• for a first set of data points, each having a number of associated parameters, eliminating first outliers as determined according to statistical properties of a first group of the associated parameters;
• establishing a first baseline based on remaining first set of data points without the first outliers;
• and
• examining a second set of data points against the first baseline for second outliers according to statistical properties of one of the associated parameters that is not included in the first group of associated parameters.

A method to detect congestion in a network traffic, comprising

• collecting Internet traffic duration information for a client;
• characterizing the Internet traffic duration information by client type and latency;
• removing packet loss outliers for each client type;
• partitioning remaining data without packet loss outliers into bins;
• setting latency threshold values for the bins;
• and
• examining the Internet traffic duration information for duration outliers as determined by the latency threshold values.
