Discovering a server device, by a non-DLNA device, within a home network

摘要

A router is configured to receive a message from a server device, store information about the server device based on the message, and receive a request from a client device. The request includes an address associated with the server device. The local router is further configured to map the address to the information and transmitting a response to the client device. The response indicates the mapping of the address to the information. The local router, the server device, and the client device are within a single local area network (LAN). The information allows the client device to detect a presence of the server device without the request being transmitted external to the LAN.

1. A method comprising:
receiving, by a router, a message from a server device; storing, by the router, information about the server device based on the message; trapping, by the router, a request from a client device in a User Datagram Protocol (UDP) port number fifty-three of the router,
the router, the server device, and the client device being within a single local area network (LAN),the client device not having Digital Living Network Alliance (DLNA) capabilities, andthe request comprising an address associated with the server device; mapping, by the router, the address to the information; and transmitting, by the router, a response to the client device,
the information allowing the client device within the single LAN to detect a presence of the server device within the single LAN by communicating with the router within the single LAN and without the request being transmitted external to the single LAN.
