Distributed network performance monitoring
First Claim
1. An apparatus comprising:
- one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the apparatus to;
monitor one or more signal quality parameters for one or more of a plurality of downstream channels;
detect one or more data payloads within an encoded data stream being transmitted on the one or more of a plurality of downstream channels, the encoded data stream comprising a plurality of video packets that comprise a watermark corresponding to one of the data payloads;
store, from the plurality of video packets, one or more video frames that comprise the watermark;
transmit, towards a source of the encoded data stream, the stored one or more video frames that comprise the watermark; and
transmit a quadrature amplitude modulation (QAM) constellation diagram generated from one of the plurality of downstream channels towards the source of the encoded data stream.

Abstract
A probe is configured to monitor one or more communication parameters on one or more downstream frequency channels carried on a communication medium of an access network. Results of repeated monitoring are stored over a predetermined period. At the conclusion of the monitoring period, data reports reflecting the stored results are transmitted in upstream frequency channels carried on the same medium. The probe can also be configured to send immediate messages if a parameter exceeds predefined limits and can store a plurality of monitoring programs and can be reprogrammed remotely. The probe can be contained within a cable tap if the medium is, e.g., a coaxial cable. Numerous probes can be deployed throughout an access network so as to provide monitoring data from each of many locations over a prolonged period.
