    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.

    Abstract: In one embodiment, a requesting device (e.g., head-end application) requests a phase-related response from an end-point that does not know its phase in a polyphase power source system. In response, the requesting device receives the phase-related response from the end-point, where the response relays an identification of the end-point and related phase information without indicating an actual phase of the end-point, e.g., on which power-line is a response generated or at which time is a zero-crossing of the power source's waveform. The phase information of the phase-related response may then be correlated to a known phase of a known-phase device, such that the actual phase of the end-point may be identified based on the correlation.

    Abstract: Security is enabled in an electrical system by examining a configuration file for a substation present in the electrical system, where the substation includes one or more electrical devices and one or more network devices. Based on the examination of the configuration file, information is determined on a characteristic of an electrical device that is selected from a group including a type, allowed role of the electrical device and allowed communication modes for the electrical device. Based on the determined information, a basis for controlling the role and communication modes for the electrical device is identified. A security policy is configured in a network device in the substation to incorporate the identified basis. Based on the configured security policy in the network device, communication patterns for the electrical device are allowed that are associated with the allowed role and allowed communication modes for the electrical device.

    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: A method is provided in one example embodiment and includes receiving phasor measurement unit (PMU) data in a first transmission; converting the first transmission into a multicast transmission; and multicasting the PMU data to a multicast group address, which identifies a plurality of subscribers. In more specific implementations, the converting of the first transmission into the multicast transmission occurs at a first-hop router in relation to a PMU source that sent the first transmission. In some cases, the first transmission is a unicast transmission sent from a network element, which includes a PMU sensor.

    Abstract: This disclosure provides a system and method for client authentication that allows a service provider to implement multiple authentication challenges to verify a user/client. The system includes an extractor, a comparer, and an attributer. The extractor receives an Internet protocol source address from a client and extracts a media access control address. The extractor also determines a source identifier of the client from the media access control address. The comparer compares the extracted media access control address with a client media access control address associated with the client, and signals execution of one or more client authentication challenges when the extracted media access control address fails to match the at least one client media access control address associated with the client. The attributer associates the source identifier with the client after successful execution of a client authentication challenge.
