Abstract
Techniques are provided herein to enable monitoring of a real-time transport protocol (RTP) packet flow in devices along the path that the RTP packet flow traversed from a source to a destination. A device that is a source or destination of a RTP packet flow transmits a monitor request message that requests one or more other devices along a path of the RTP packet flow to monitor the RTP packet flow. The device that is the source or destination of the RTP packet flow receives one or more monitoring reports from the one or more other devices along the path of the RTP packet flow. This allows a device that requested monitoring of the RTP packet flow to analyze the monitor reports in order to determine a location of a cause of reduced performance in the RTP packet flow. e.g., missing packets, overly delayed packets, etc.
