A network fault detection method and related network elements

Abstract

The embodiment of the invention discloses a network fault detection method, which is used to accurately reflect the actual state of the current network. The method in the embodiment of the present invention includes: the front-end network element sends multiple session request messages to the back-end network element; receives multiple response messages corresponding to the multiple session request messages; The response message calculates a delay parameter, and the delay parameter is used to indicate the delay status of the plurality of response messages corresponding to the plurality of session request messages; the front-end network element judges whether the network status is normal according to the delay parameter . The method provided by the embodiment of the present invention can reflect the influence of the current network condition on the waiting time of the user, and thus can reflect the actual state of the current network more accurately than the method provided in the prior art. The embodiment of the present invention also provides related front-end network elements.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network fault detection method and related network elements. Background technique [0002] In the communication system, the network between network elements is often in a sub-healthy state, which is manifested in packet loss, error packet, delay, jitter, one-way communication, network congestion, insufficient bandwidth, etc., resulting in unsmooth network services , the user experience is degraded. Due to the complexity of network protocols and the diversity of environmental interference, network sub-health is an unavoidable phenomenon. Therefore, timely and accurate detection of sub-health status of the network is extremely valuable for optimizing network services and improving user experience. The current technology uses the following method to detect the sub-health state of the network: In the communication system, the network element at one end sends a detection message ...

AI Technical Summary

Problems solved by technology

But in fact, the current network is already in a sub-healthy state, and users need to spend a lot of time waiting for the session to be connected

Therefore, the indicator of connection rate cannot reflect the impact of current network conditions on user waiting time, so it cannot accurately reflect the actual state of the current network
