Abstract

The invention relates to a method and device for updating a routing information table based on a monitored device. The method comprises the following steps: an edge routing node edge receives an indication message issued by a filtering gateway and used for indicating that an aggregation unit is interested in the monitored device in a target device type, and monitors mass Internet of Things data reported by mass terminal devices within a wireless coverage range of the edge routing node, and when the mass Internet of Things data comprise a plurality of Internet of Things data in which the device identifiers of the contained terminal devices are not stored in a pre-generated routing information table, the edge routing node judges whether the plurality of Internet of Things data comprise at least one Internet of Things data in which the device type of the contained monitored device is the target device type, if so, adds the device identifier of the monitored device contained in the at least one Internet of Things data to the routing information table, and if not, controls to not update the routing information table. By implementation of the method and device provided by the embodiment of the invention, the updating times of the routing information table are reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a method and device for updating a routing information table based on a monitored device. Background technique [0002] In the Internet of Things architecture, the terminal equipment used for the data content of the monitored equipment (such as irrigation equipment, engine equipment, etc.) and reporting the IoT data including the data content is an important part of the network topology of the Internet of Things architecture, so , the relevant information of the newly online terminal device (such as the device identification of the terminal device, etc.) needs to be updated in time to the edge routing node covering the newly online terminal device, so as to add the newly online terminal device to the network of the Internet of Things architecture. in the road topology. In practical applications, whenever there is a new online terminal device within the wireless co...
