1. A method for reducing communication network performance degradation using in-band telemetry data, comprising:
at a first network element of a communication network, generating first telemetry data based on in-band telemetry data of downlink data structures that pass through the first network element while flowing from a second network element upstream of the first network element to a shared communication link downstream of the first network element, the shared communication link communicatively coupling the first network element to a plurality of termination devices;
sending the first telemetry data to an analytics engine of the communication network that is upstream of the shared communication link;
determining from the first telemetry data that there is performance degradation in at least a portion of the communication network; and
in response to determining that there is performance degradation in at least the portion of the communication network, sending a message from the analytics engine to the second network element.
