Systems and methods for accelerated network impairment mapping

A method, comprising:

• receiving, by one or more processors, from a subset of downstream household devices on a network, telemetry data associated with a performance of the subset of downstream household devices;
• determining, based on the telemetry data, a value of a micro-reflection at a first household device, wherein a micro-reflection is a short time delay echo or reflection caused by an impedance mismatch;
• determining that the value of the micro-reflection is greater than a threshold value;
• determining that a first impairment exists at a first downstream household device of the subset of downstream household devices;
• requesting, based on the determination that the first impairment exists at the first downstream household device, telemetry data from one or more neighboring household devices to the first downstream household device;
• determining, based on the telemetry data from the one or more neighboring household devices, that a second impairment exists at a second downstream household device of the one or more neighboring household devices;
• and
• determining a lowest common ancestor to the first downstream household device and the second downstream household device on the network.

A non-transitory computer readable medium including computer-executable instructions stored thereon, which when executed by one or more processors of a wireless access point, cause the one or more processors to perform operations of:

• receiving, by one or more processors, from a subset of downstream household devices on a network including at least one device upstream from the subset of downstream household devices, telemetry data associated with the performance of the subset of downstream household devices, wherein the subset of downstream household devices comprises only devices that are located furthest downstream in the network;
• determining, based on the telemetry data, a value of a micro-reflection at a first household device, wherein a micro-reflection is a short time delay echo or reflection caused by an impedance mismatch;
• determining that the value of the micro-reflection is greater than a threshold value;
• determining that a first impairment exists at a first downstream household device of the subset of downstream household devices;
• requesting, based on the determination that the first impairment exists at the first downstream household device, telemetry data from one or more neighboring household devices to the first downstream household device;
• determining, based on the telemetry data from the one or more neighboring household devices, that a second impairment also exists at a second downstream household device of the one or more neighboring household devices;
• and
• determining a lowest common ancestor to the first downstream household device and the second downstream household device on the network.
