Abstract: In one implementation, a protocol for dissemination of information, such as configuration information, in a computer network is provided. The dissemination of the payload or content is separated from the dissemination of the fact that a new revision of that payload or content exists. The availability of a new revision of the payload or content is signaled prior to the transfer. Only nodes receiving the notice of existence of the new revision and requesting the new revision receive the payload or content. While the payload or content revision notifications potentially arrive at a receiving node from many different neighbors, the payload or content is only requested once by the receiving node and transmitted once over links between neighbors. This scheme may result in low end-to-end delays and in resiliency.

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.
