METHODS AND SYSTEMS FOR NETWORK PERFORMANCE MEASUREMENT USING VERIFIABLE SINGLE-USE HIGHLY-ENTROPIC FILE GENERATION

摘要

A network performance measurement relies on the transmission of a verifiable, single-use, highly-entropic file across the network. Upon receiving a network performance measurement query from a user equipment (UE) device communicating through a mobile communication network, a test utility (TU) server generates a test file having high entropy such that it does not reduce substantially in size when compressed using standard compression algorithms. The test file is assigned a filename including a variable component, and the file is transmitted to the UE device. Information relating to the transmission of the test file is logged, and a network performance measurement value for the transport of the high-entropy test file to the UE device is computed based on the logged information. In one example, hash-value computations are used to verify that the test file received in the UE device is complete and accurate.

1. A method comprising:
in response to receiving in a test utility (TU) server a network performance measurement query identifying a user equipment (UE) device communicating through a mobile communication network, generating a test file having high entropy; assigning to the test file a filename comprising a variable filename component; transmitting the high-entropy test file from the TU server to the UE device using the assigned filename; logging information relating to the transmission of the high-entropy test file on the TU server; and computing a network performance measurement value for transport of the high-entropy test file from the TU server through at least the mobile communication network to the UE device based on the logged information.
