ABSTRACT:
No-op media payload packets are used to analyze a media path in a packet switched network. In one embodiment, the no-op packets are Real Time Protocol (RTP) payload packets that contain no media content. A Real Time Control Protocol (RTCP) report is generated for the received RTP no-op packets. A marker bit is set in one of the no-op packets that triggers the no-op packet receiver to send back the RTCP report. The media steam is transmitted when the statistics in the RTCP report indicate a viable media path.
