Abstract
Systems and methods of monitoring packet delivery are disclosed. In an embodiment, a method is disclosed that includes querying multiple network devices for performance metrics corresponding to video data packets sent from a video server. The network devices may include multicast branching points between the video server and the destination. A delivery failure may be identified based on the performance metrics, and a response to the delivery failure may be initiated.
