Embodiment Construction

[0032] The specific implementation of the mDNS-based service announcement and service discovery method provided by the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] It should be noted that in order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, in the drawings or descriptions of the specification, similar or identical parts all use the same figure numbers.

[0034] The service announcement and discovery according to the exemplary embodiment of the present invention is to announce and discover the service from the application point of view after the device is connected to the network. The service announcement and discovery protocol is based on mDNS (RFC6762), and uses the multicas...

Abstract

The present invention provides a method for announcing and discovering services based on mDNS in a local area network and a wide area network, wherein the method for announcing services based on mDNS in a local area network includes: the first application in the local area network generates an mDNS message, wherein the mDNS The message contains brief information of the announced service; the first application sends the mDNS message in the local area network; the first application receives the declared service from at least one second application in the local area network that is interested a query of the service; and the first application generating and sending a response message to the second application in response to receiving the query, wherein the response message contains detailed information of the announced service.

Description

technical field [0001] The present disclosure relates to the Internet of Things, in particular, to a method for service announcement and service discovery based on mDNS. Background technique [0002] With the continuous development of the Internet of Things and smart homes, more and more smart devices are used by more families, such as smart lights, smart sweeping robots, smart washing machines, etc. During use, the user can view and control these smart devices through a control device such as a mobile phone. [0003] However, if you want to discover smart devices in the network, you can specify a new discovery message, but this method is not scalable, and the devices cannot identify each other. [0004] At present, the above-mentioned problems are mainly solved by adopting a zero-configuration networking protocol (bonjour). Bonjour is an open zero-configuration networking standard based on Multicast Domain Name Service (mdns). Devices using bonjour automatically broadcas...
