Network fault node diagnosis method

Abstract

The invention discloses a method for diagnosing network fault nodes. According to the engineer's daily test process, firstly, automatic test software can be developed to simulate the entire process from detecting network paths to finding network fault nodes according to a specified protocol; secondly, for each network device The node can use the selected protocol (TCP, UDP) to complete the automatic test: the whole test process only needs to fill in the destination network address, and then the faulty node can be automatically diagnosed according to the network connectivity. This method can automatically detect network failure nodes, and firstly use the faster ICMP protocol in routing tracing, and at the same time use UDP routing tracing as a backup to ensure the probability of finding a complete route; at the same time, the method of detecting node connectivity is flexible and effective. In actual work, it can effectively assist the diagnosis of network faults.

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.
