    摘要： When capturing packets at the application level for the purpose of QoS monitoring, a QoS monitor needs to be bound to the same IP address and port as those of a media player. However, due to the unicast duplicate binding problem, a unicast packet captured by the QoS monitor will not be received by the media player, which means the QoS monitor have affected the operation of the media player. The present invention provides a solution to make the QoS monitor, upon the receipt of a unicast packet, forward the packet to the socket of the media player. In order to guarantee that the forwarded packet can be received by the socket of the media player, the QoS monitor needs to keep the port unchanged and replace the destination IP address with the local host address (127.0.0.1). According to the invention, the QoS monitor can sniff the media player without interference to the normal operation of the media player.

    摘要翻译： 为了进行QoS监控，在应用层捕获数据包时，需要将QoS监视器绑定到与媒体播放器相同的IP地址和端口。 然而，由于单播重复绑定问题，由QoS监视器捕获的单播数据包不会被媒体播放器接收，这意味着QoS监视器影响了媒体播放器的操作。 本发明提供了一种在接收到单播分组时使QoS监视器将分组转发到媒体播放器的套接字的解决方案。 为了保证转发报文能够被媒体播放器的套接字接收，QoS监视器需要保持端口不变，并用本地主机地址替换目的地址（127.0.0.1）。 根据本发明，QoS监视器可以嗅探媒体播放器而不干扰媒体播放器的正常操作。
