Method and system for emulating adaptive network traffic packet patterns of interactive services for measuring user experience

A computer-implemented method for optimizing and/or troubleshooting a wireless network configured to support interactive over-the-top (OTT) service by estimating a user experience metric (UEM) of the interactive over-the-top (OTT) service using a network traffic client node and a network traffic server node, the method comprising:

• (a) exchanging network packets between the client node and the server node during predetermined time windows, thereby forming packet trains having network traffic packet patterns;
• (b) obtaining a number N≥2 network metrics based on the exchanged network packets during the predetermined time windows, the N network metrics including round-trip-time (rtt) and at least one of packet loss (pl), random jitter (rj) and spiky jitter (sj), where:
• rtt and pl are measured network metrics;
• rj is a statistic of variations in rtt;
• and
• sj is a statistic reflective of the largest variation of rtt;
• (c) determining the user experience metric estimate (UEM) based on the obtained network metrics;
• and
• (d) in response to the obtained network metrics, dynamically adapting subsequent packet trains such that their network traffic packet patterns emulate network traffic packet patterns of the interactive over-the-top (OTT) service.
