Network fault node diagnosis method

Abstract

The method for diagnosing network fault nodes (NFN) includes following steps: first, based on testing flow routine utilized by engineers to develop automatic testing software to simulate entire procedure from detecting network paths to searching NFN; then, based on each network device node to use selected protocol (TCP,UDP) to accomplish automatic test; based on network connectivity to accomplish diagnosing fault nodes automatically except only address of target network needs to be filled in for entire testing procedure. The method uses ICMP protocol with quick speed for tracking routes first, and then backs up routes tracked by UDP so as to guarantee probability to find complete route. Moreover, being flexible and effective to detect connectivity of nodes, the method can help to diagnose network fault effectively in practical work.

Description

technical field [0001] The invention relates to a network technology, in particular to a network fault node diagnosis method. Background technique [0002] At present, as the network environment becomes increasingly complex, the work of testing and diagnosing network connectivity becomes increasingly complicated. Network engineers often need to use a variety of testing equipment and testing methods to guess the network topology and test possible fault points one by one. The determination of fault points becomes the difficulty of network connectivity testing. [0003] Network engineers often need to use general ping, transrouter and other tools to determine the network path to the destination address, but due to security considerations, the network equipment often prohibits the protocol that this command relies on - ICMP, so that engineers cannot know the complete path Node information; at the same time, in terms of node connectivity testing, engineers often need to use UDP,...

Problems solved by technology

[0003] Network engineers often need to use general ping, transrouter and other tools to determine the network path to the destination address, but due to security considerations, the network equipment often prohibits the protocol that this command relies on - ICMP, so that engineers cannot know the complete path Node information; at the same time, in terms of node connectivity testing, engineers often need to use UDP, TCP, HTTP and other protocols to test in order to finally determine the location of the fault point, which often requires professional testing tools or testing software

In short, there is a lack of an effective automatic test method for the diagnosis process of network fault nodes.
