Abstract
A network device sends into a network a request to be connected to a particular multicast source-group pair for a Phasor Measurement Unit (PMU) data stream comprising packets containing phasor measurement data. The network device receives the phasor measurement data stream for the particular multicast source-group pair. The source-group pair information is compared against stored data specifying handling rules for packets associated with phasor measurement data streams. The packets in the received phasor measurement data stream are modified when there are handling rules in the stored data for the particular multicast source-group pair of the received phasor measurement data stream. The packets (now modified) for the phasor measurement data stream for the particular multicast source-group pair are re-originated with a new multicast source-group pair and sent into the network. In order to support existing legacy PMU devices, IP unicast-to-multicast conversion is implemented.
