Abstract
Systems and methods for measuring and reporting the performance of communications traffic in a Passive Optical Network (PON) are disclosed. According to the disclosed embodiments, the PON network may include an Optical Line Terminal (OLT) and multiple Optical Network Terminals (ONTs) downstream of the OLT. By aggregating multicast communications traffic received by the ONTs at a point downstream of the ONTs, selectively accessing the aggregated communications traffic, collecting information representative of performance of each selected communications traffic, and reporting the collected information upstream to a network management node, communications traffic in the PON network may be tested in both downstream and upstream directions. Advantages provided by the disclosed embodiments include simplification of the testing process by consolidating all performance reports in one place, enabling more flexible testing, and creating value from the collected information, such as by using the collected information in conjunction with simulation tools during customer deployment.
