Abstract: Providing a method and software solution to add robustness to real-time media streams such as voice, video and audio streams on a network. When the network channel carrying the media stream experiences an adverse condition that affects the transmissions, such as high packet loss or corruption of packets, a robust mode is activated at an intermediate node of the end-to-end transmission for the media stream to the destination link. The robust mode of the present invention may be activated on specific network links that are experiencing the network problems and not necessarily on the end-to-end communication path. Under certain conditions, an intermediate network node may terminate robust mode in packets received from an upstream link when the network channel in question no longer experiences the adverse network condition.
