推荐答案

你想找到一个特定的设备？或者你需要的所有连接的设备的清单？我不认为第二个是可能的。

Would you like to discover a specific device ? Or you need the list of all connected devices? The second I don't think is possible.

修改

发现特定设备：
使用 UDP广播。有一定的参考，可以发现<一href="http://http://www.nakov.com/inetjava/lectures/part-1-sockets/InetJava-1.5-UDP-and-Multicast-Sockets.html"相对=nofollow>这里！

Discovering specific devices:
Using UDP Broadcast. Some reference can be found here!

有被一些设备支持一些协议（路由器，硬盘，等等），如 UPNP ！

There are some protocols that are supported by some devices( routers, HDD, etc...), like UPNP!

如果你开发，你将要为其发现你可以创建一个 UDP 服务器侦听特定端口上的设备上的软件。 您的客户端将只发送播出消息，端口和您的服务器将发送您所需要的信息的响应。 这里的是一个简单的例子。

If you develop a software on the device which you would like to discover you could create a UDP server listening on a specific port. Your client will just send a broadcast message on that port and your Server will send a response with the information you need. Here it is a simple example.
