Equipment network connectivity detection method and device, terminal equipment and storage medium

Abstract

The invention discloses an equipment network connectivity detection method. The method comprises that when detection time is arrived, whether equipment to be detected and a target network node are inthe same network segment is determined; if YES, whether the IP address of the target network node changes relative to that in last detection time is determined; when the IP address does not change, whether a network between the equipment to be detected and the target network node is connected in the last detection time is determined; if the network in the last detection time is connected, whetherthe equipment to be detected receives a data message of the target network node in the last detection time and the present detection time is determined; and if the equipment to be detected receives the data message, the network at the present detection time is determined to be connected. Thus, the equipment network connectivity can be detected, the sending frequency and amount of the broadcast message are reduced, and the network utilization rate is improved.

Description

technical field [0001] The present invention relates to the technical field of computer network communication, in particular to a device network connectivity detection method, device, terminal device and storage medium. Background technique [0002] With the rapid development of computer network communication technology, the difficulty of managing each node device of the network is also increasing. Network connectivity is an important factor in network management to ensure the normal operation of the network. By detecting the connectivity between network node devices, not only can the network performance parameters of the links between nodes be obtained, but also the link can be understood early based on these data. It is of great significance to the management and maintenance of the network to accurately locate the connectivity faults between network devices. [0003] Currently, the connectivity between a network device and a target network node is usually detected through...

However, some network devices currently prohibit PING, or the target network node may not respond to the ICMP Echo Reply message due to anti-virus protection, firewall rules, etc. Network connectivity; and the APR detection mechanism, because it uses the mechanism of broadcasting and sending messages, therefore, a device will generate more broadcast messages when it makes an ARP request. If the device in the same network segment has multiple network Devices are using the ARP detection mechanism to detect network connectivity, so there will be more ARP broadcast packets in total, which will occupy network resources to a certain extent
