Ethernet over Coax (EoC) link failure detection system and method

Abstract

The invention provides an Ethernet over Coax (EoC) link failure detection system and an EoC link failure detection method. The EoC link failure detection system comprises EoC terminal equipment and management equipment, wherein the EoC terminal equipment captures a fixed number of data packets of a given type from user equipment, and counts the number of the captured data packets of the given type; and the management equipment receives a counting result from the EoC terminal equipment, performs analysis to determine whether to execute link detection between the EoC terminal equipment and the user equipment, and informs the EoC terminal equipment to detect a link failure between the EoC terminal equipment and the user equipment if a difference between the number of the data packets, captured by the EoC terminal equipment, of the given type and the fixed number is greater than a preset threshold value. By the system and the method, the depot rate of the EoC terminal equipment and the frequency of a maintainer going to a field for failure diagnosis can be reduced, failure processing efficiency is improved, and the maintenance cost of an operator and an equipment provider is decreased to a certain extent.

Description

technical field [0001] The present invention relates to the field of link failure detection, and more particularly, to a detection system and method for an Ethernet data transmission (EoC) link over a coaxial cable. Background technique [0002] EoC link fault detection refers to the method of detecting the EoC transmission link through the cooperation of the user when the user reports that there is a problem with the terminal service, but the management link of the EoC device is relatively smooth, so as to quickly locate the fault. EoC link failure detection can be divided into the following two parts in terms of network topology: [0003] (1) Link failure detection between EoC terminal equipment and user PC. Usually, the ping proxy, wired port detection and network cable detection methods are used to confirm whether the link between the EoC terminal device and the user PC is normal. [0004] (2) Link fault detection between EoC terminal equipment and EoC central office e...

If the above solutions cannot solve the problem, replace the EoC terminal equipment

[0006] The disadvantage of the existing technical solution is that, due to the complex and diverse installation environment of the EoC local end equipment, the current EoC fault diagnosis method will increase the difficulty of maintenance of the EoC local end equipment, reduce the processing efficiency of faults, and cause more frequent Replacement of EoC terminal equipment, thus increasing the operator's cost input
