该应用程序使用SIP和STUN建立连接并通过NAT和防火墙。视频和音频数据通过UDP流传输。
The application uses SIP and STUN to establish connections and get through NAT's and Firewalls. The video and audio data are transfered via UDP stream.
我知道Silverlight具有出色的媒体和流媒体支持，但它是否为这种情况提供了必要的功能？

推荐答案
Silverlight在Socket方面有严重的限制。在SL 3中，您只能连接到一小部分端口号（大约十几个），而且您连接的主机必须有一个位于XYZ端口的服务（不记得号码）将特殊策略文件发送给客户端。不用说，这更像是一个幻想而不是每个主人都会拥有的东西。阅读详细信息此处。
Silverlight has severe limitations in Socket aspect. In SL 3 you are allowed to connect only to small subset of port numbers (about a dozen of them), and additionally the host you are connecting to must have a service sitting on the port XYZ (don't remember the number) that will send the special policy file to the client. Needless to say that this is more a fantasy than something that each host would have. Read the detailshere .
