  An approach to enable advanced troubleshooting, granular analysis and service
quality of experience assessment is presented. The use of topology information
in the identification of each cable network element along with granular
information of the element configuration and health is proposed. This technique
covers multiple layers including the service layer. At the physical layers
street addresses, taps and amplifiers are used to identify impairment location.
All layers are leveraged to measure network and service reliability, service
degradation and to quantify quality of experience. A cable infrastructure
implementation is described as an example.
