Abstract

The embodiment of the invention discloses a method, a system and a device for detecting and positioning a network failure. The method comprises the following steps that: a source measuring point determines whether a reverse status indicating RSI message from forwarding equipment is received within the preset time or not; when the RSI message from the forwarding equipment within the preset time isnot received, the source measuring point determines that a detected network generates the failure and the forwarding equipment is a failure point. The embodiment of the method can realize quality detection of end-to-end of a network and network piecewise links, detect whether the network generates the failure or not, and position the failure point when the network generates the failure.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method, system and device for detecting and locating network faults. Background technique [0002] At present, the era of all-IP (Internet Protocol, the protocol for interconnection between networks) of mobile networks has arrived. All-IP is already the trend of future business development. All-IP is to enable anyone to use any terminal at any time and any place All for a consistent and seamless experience. More and more traditional telecommunication services and emerging services will be carried by IP networks, so as to obtain features such as high bandwidth utilization of new services. However, because the design concept of the IP network is very different from that of the traditional circuit network, it faces many problems in network monitoring, QoS (Quality of Service, quality of service), security detection, etc. [0003] In the prior art, a method for detecting n...
