A method includes receiving, at a processor of a network device, data packets to be communicated to a multicast destination. The method includes recording, with the network device, performance data associated with the data packets, where the performance data is associated with a performance metric. The method includes determining, with the processor, a trend based on the performance data. The method also includes sending a warning from the processor to a performance server based on the trend satisfying a condition.

System and method of monitoring video data packet delivery

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.

A system and method for registration of network units is disclosed. A system that incorporates teachings of the present disclosure may include, for example, an optical network unit (ONU) in a passive optical network (PON) that can have a controller element to receive a registration code, send the registration code and a serial number of the ONU to an optical line terminal (OLT) that configures the ONU for temporary connectivity with the PON, and upon an expiration of the registration code or a termination of the temporary connectivity, re-send the serial number to the OLT to re-configure the connectivity with the PON. Additional embodiments are disclosed.
