A quality analysis of DOCSIS Cable Modem

This paper presents the quality analysis service of cable modem in HFC network (Hybrid Fiber Coaxial) according to standard DOCSIS (Data Over Cable Service Interface Specifications) by using the quality index network 9 to specific the equipment in HFC network system that working in appropriate level to send and receive data from user. The parameter of the forward path and the parameter of the forward path return path are collected by CMTS (Cable Modem Termination System), which communicated with the cable modem will use to analyze the efficiency of working. The paper show the benefit of network data analysis by the quality index network 9. Not only tell how the efficiency of network but also bring it to solve the problem in the HFC network.
