Quality of user experience analysis

One or more non-transitory computer-readable media having computer-executable instructions stored thereon that, when executed by a computing device, cause the computing device to perform operations comprising:

• receiving a first trace file from a device engaged in wireless packet-based communication, the trace file including first data for a first layer of a communication protocol stack of the device;
• receiving a second trace file including second data for a second layer of the communication protocol stack, the second data being from a different layer than the first layer of the communication protocol stack;
• correlating, as correlated data, the first data with the second data based on a payload of a packet, the packet represented by the first data and the second data;
• and
• based on the analyzing, determining that the wireless packet-based communication exhibits a reduced quality of user experience (QoE) based on one or more of communication performance thresholds or communication performance models.

A system comprising:

• a trace file receiving module configured to receive at least one trace file from each of a plurality of devices involved in communicating data packets, each trace file including data that is for the data packets and is associated with at least one different layer of a multi-layer communication protocol stack of a corresponding device;
• a trace file correlation module configured to:
• correlate, as correlated data packets, the data packets horizontally across the trace files for the plurality of devices, and
• for each having two or more trace files that include data for multiple layers of the multi-layer communication protocol stack of the device, correlate the data packets vertically between the layers;
• and
• a cross file analysis module configured to analyze the correlated data packets to identify one or more of the plurality of devices causing a problem that degrades a QoE associated with communicating the data packets.
