Abstract

The invention provides an internet access state detection method, device and system. The method is applied to detection device and comprises the following steps: receiving a detection instruction; according to the detection instruction, capturing a network data packet sent by the to-be-detected device through a network port of the to-be-detected device; and judging whether the network port is normal or not according to the network data packet. In the process of detecting whether the internet access is normal or not, the operation is simple, the detection time is short, and the accuracy of thedetection result is high.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method, device and system for detecting the state of a network port. Background technique [0002] In the production process of enterprises, product quality is a reliable guarantee for enterprises to obtain economic benefits, and product functional testing has always been a necessary process for enterprises to test whether products are qualified. [0003] Among them, the network port detection of smart products is a part of product functional detection. The traditional network port detection method is to build a DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) server, and then through the network Then, according to whether the smart product to be checked can obtain the IP address assigned by the DHCP server, it is judged whether the network port of the smart product to be checked is normal. However, using the method of building DHCP...
