Abstract

The invention applies to the technical field of networks, and provides a method and a device for discovering network devices. The method for discovering the network devices includes: receiving first messages which are sent by the network devices in the same local area network through a designated port and carry description information of the network devices; parsing the first messages, and obtaining the description information of the network devices from the first messages; updating a device list according to the obtained description information of the network devices. The method for discovering the network devices defines a device discovery protocol based on a UDP (user datagram protocol), achieves device discovery in the same local area network, achieves the device discovery process in an application layer not in a non-link layer, is few in interacting number and simple to achieve, and can guarantee instantaneity of the device discovery.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a method and device for discovering network equipment. Background technique [0002] With the development of network technology, more and more network devices appear in the LAN. The network devices located in the same LAN can be discovered through the device, which can synchronize configuration, share data, avoid conflicts, and even realize intelligent optimization of the network topology. Users can also obtain network device information in the LAN through device discovery, so as to manage and operate network devices in the LAN. [0003] At present, commonly used network device discovery protocols include Link Layer Discovery Protocol (LLDP), Cisco Discovery Protocol (Cisco Discovery Protocol, CDP), Extreme Discovery Protocol (Extreme Discovery Protocol, EDP), Link Layer Topology Structure discovery (Link Layer Topology Discovery, LLTD), etc. However, the above-ment...
