Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] figure 1 It exemplarily shows a typical network architecture to which the service discovery solution provided by the embodiment of the present invention can be applied.

[0029] like figure 1 As shown, the network architecture includes smart devices that can provide services, terminals that can use services, and routers that implement communication between devices.

[0030] There may be multiple smart devices, and there may be mul...

Abstract

The invention discloses a router multicast function detection method and device. The method comprises the following steps: sending a service query request message by a terminal by use of a first discovery protocol; creating and performing a first thread and a second thread, wherein the first thread is used for monitoring a broadcast message sent by a router according to the service query request message, while the second thread is used for monitoring response messages sent by multicast group members according to the broadcast message sent by the router; if the first thread receives the broadcast message sent by the router according to the service query request message within set time, terminating the first thread and determining that the router supports a multicast protocol corresponding to the first discover protocol; and if the first thread does not receive the broadcast message sent by the router according to the service query request message within the set time, terminating the first thread and the second thread and determining that the router does not support the multicast protocol corresponding to the first discover protocol. The router multicast function detection is capable of realizing detection on the multicast function of the router and improving the service discovery efficiency.

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 a 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 an...
