The invention discloses a method for quantitatively evaluating the bidirectional network operation performance of a cable television, which comprises the following steps that: 1) evaluation indexes NDR, TDR and EDR for time characteristics of three parameters, i.e. noise, throughput and error rate, wherein, by virtue of the parameters indicating the time characteristics, the degree of degradation of the operation performance of a cable modem termination system can be known more accurately and the degree of impact caused by network degradation to user experience can be known; and 2) in order to more intuitively compare the health condition of the operation of the CMTS and simplify evaluation results, the system converts signal to noise ratio and the error rate into a centesimal-system scoring value DMS through integrated computation, wherein the DMS can indicate the health degree of the network operation or the magnitude of errors generated during the network operation. The method for quantitatively evaluating the bidirectional network operation performance of the cable television is of a very great significance to knowing the overall network performance or the performance of any area, the change of the performance can be seen intuitively and easily, and a very strong guide effect is taken to network planning, reconstruction, optimization, maintenance and the like.
Description
Technical field [0001] The invention relates to a method for quantitatively evaluating the operating performance of a cable television network. Background technique [0002] At present, the entire network has basically realized the two-way transformation of HFC and the overall conversion of digital TV, and has actively expanded services such as wired broadband, interactive TV, virtual private network, high-definition TV, and pay TV, and the development momentum is good. In the technical standards of the cable television industry, a series of technical indicators are specified, but they are isolated and reflect certain technical characteristics. It is impossible to determine the network in a certain time range based on the specific figures of one or several indicators. It is impossible to quantify (digitally) grasp the health of the network. [0003] Network indicators change all the time. The amount of change and the time of each change can only be recorded with a huge database. I...
