Abstract

See full text

Apparatus and method for monitoring IP multicast delivery. One embodiment comprises an Optical Line Termination (OLT) device that includes a Network Termination (NT) device that connects to a core network, and a plurality of Line Termination (LT) devices that connect to an optical distribution network. The NT device generates an IP multicast monitoring stream directed to a group address, and transmits the monitoring stream to the LT devices. The LT devices then monitor for packets directed to the group address. When an LT device detects a loss of one or more packets directed to the group address, the LT device reports packet loss for the IP multicast monitoring stream to the NT device.
