Abstract: A method is provided in one example embodiment and includes receiving a request for a service that involves phasor measurement unit (PMU) data; identifying a service device in a network to perform the service; and multicasting one or more results of the service to a group of subscribers identified by a multicast group address. In more particular embodiments, particular PMU data is redirected to the service device via a service insertion architecture (SIA) protocol. In addition, the service can include replicating packets and masking a subset of traffic for forwarding to a first hop router of the network. In certain example instances, metadata is used in order to apply the service to certain traffic propagating in the network.

Abstract: In an example embodiment, packets for a selected flow are replicated and sent over one or more diverse paths, such as a primary path and at least one secondary path, to a destination switching device. At the destination switching device, one copy of the replicated packets is selected for delivery to the destination, and the remaining copies are discarded. In the event that packets are not received at the destination switching device due to loss of connection on the primary path or packets are not timely delivered due to congestion on the primary path, a different path may be selected as the primary path.

Abstract: At a network device of each of a plurality of generator substations that is connected to a multi-terminal transmission line, phasor measurement data produced by a phasor measurement unit at the generator substation is assigned to a multicast stream. A request is received from a network device at any of the plurality of the generator substations to join the multicast stream so that a destination device at any of the plurality of generator substations receives the phasor measurement data carried by the multicast stream. The multicast stream is sent for distribution to one or more destination devices at respective ones of the plurality of generator substations.
