Abstract
A device is configured to receive packet timing data, from multiple network devices, for subscriber application traffic over an Internet Protocol (IP) wireless access network and to calculate, based on the packet timing data, timing latencies for a particular subscriber flow. The device is configured to retrieve Quality of Service (QoS) timing specifications for the particular subscriber flow and to determine when the calculated timing latencies for the particular subscriber flow fail to meet the QoS timing specifications for the particular subscriber flow. The device is configured to identify one or more of the network devices that are causing the particular subscriber flow to fail to meet the QoS timing specifications and to instruct the one or more of the network devices to modify QoS parameters for the particular subscriber flow to improve timing latency for the particular subscriber flow.
