在ADSL公网上传输大量视频数据的最佳解决方案，征求网络编程高手的意见！谢谢！

Question

需要通过一台在公网上的计算机把获取的大量视频音频数据转发到公网上的其他机器上去：目前的解决方法：
0、目前是在服务器上建立TCPServer（用的是8000以后的端口）,然后在客户端连接该服务器，发现在有些装有防火墙的计算机上收不到数据，不装防火墙的机器一切正常。问题：
1、使用UDP方式传输数据完全不成功，即所有客户端都收不到数据，为什么？
2、听说过“Http隧道”和“TCP80”这两种方式，它们是否是一样的技术？
3、若考虑传输性能，那种方式是最好的？
4、若考虑在ADSL公网上传输的兼容性，那种方式最好？初学网络编程，请大家多多指教，谢谢！

Answer 1

RTP/RSTP适合于在线播放吧，呵呵

Answer 2

在哪里能找到关于RSTP的编程和实现方法呢？谢谢！

Answer 5

怎么用TCP啊！
传输语音视频数据用UDP
如果有实时的要求就使用RTP/RTCP传。
否则直接用UDP

Answer 6

应该是UDP的，TCP太慢！当然是有可能丢数据的。我们公司的视频监控系统就是用的UDP效果还不错。
