Quality of user experience analysis

摘要

The techniques described herein involve analysis of communication data included in trace file(s) of device(s) involved in a communication. These trace file(s) may each include data associated with multiple layers of a communication protocol stack of a respective device or data associated with a single such layer. The techniques may further involve one or more of determination of performance metrics associated with data at a specific layer of a specific device, correlation of the data between layers of a device, or correlation of data across multiple device(s) involved in the communication. The performance metrics or correlated data may then be analyzed based on thresholds or models to determine whether the performance metrics or correlated data exhibits a degraded quality of user experience. Also or instead, graphic or textual representations of the performance metrics or correlated data may be generated.

1. A method comprising:
receiving a trace file from a device engaged in wireless communication, the trace file including at least first data associated with a radio layer of a communication protocol stack of the device, second data associated with an Internet layer of the communication protocol stack of the device, third data associated with a network layer of the communication protocol stack of the device, and fourth data associated with a transport layer of the communication protocol stack of the device; correlating the first data with at least one of the second data, the third data, or the fourth data based on a payload of a packet, the packet represented by the first data and the at least one of the second data, the third data, or the fourth data; analyzing the correlated data based on one or more of communication performance thresholds or communication performance models; based on the analyzing, determining one or more performance metrics associated with key performance indicators for the device based at least in part on the first data and the at least one of the second data, the third data, or the fourth data; and generating one or more graphic or textual representations of the one or more performance metrics.
