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.
