Abstract

The invention discloses a router multicast function detection method and device. In this method, the terminal uses the first discovery protocol to send a service query request message; create and execute a first thread and a second thread, the first thread is used to listen to the broadcast message sent by the router for the service query request message, and the second thread uses It is used to monitor the response message of the multicast group member to the broadcast message sent by the router; if the first thread receives the broadcast message sent by the router for the service query request message within the set time, the first thread is terminated, and it is determined that the router supports The multicast protocol corresponding to the first discovery protocol; if the first thread does not receive the broadcast message sent by the router for the service query request message within the set time, then terminate the first thread and the second thread, and determine the router The multicast protocol corresponding to the first discovery protocol is not supported. The invention can realize the detection of the multicast function of the router and improve the efficiency of service discovery.

Description

technical field [0001] The invention relates to the communication field, in particular to a router multicast function detection method and device. Background technique [0002] With the development of smart devices, multi-screen interaction has been more and more widely used. [0003] Multi-screen interaction refers to, based on protocols such as DLNA (Digital Living Network Alliance), AirPlay (wireless communication technology developed by Apple Inc.) or proprietary protocols, through wireless local area network connection, on different multimedia terminals, multimedia (such as audio, video, pictures, etc.) content transmission, display and other operations. [0004] Among them, the discovery protocol that provides the service discovery function is a very important part. Its main function is to discover the address of the smart device that provides multi-screen interactive services in the local network, so as to establish a connection with the discovered smart device and a...
