    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: Techniques are provided for adaptive routing of authentication packets in a network, such as a wireless mesh network. At an authenticated device in the network, an authentication packet is received over the network from a device that is seeking authentication. The authentication packet is encapsulated for transmission in Layer 3 packets over an Internet Protocol (IP) tunnel to an authenticator device associated in the network. Similarly, for an authentication packet encapsulated in Layer 3 packets from the authenticator device over the IP tunnel, the authentication packet is decapsulated from the Layer 3 packets and transmitted over the network to the device seeking authentication.

    Abstract: In one embodiment, a subnet-scoped multicast packet is received on an interface of a forwarding device that is connected to a host device of a subnet of a forwarding domain. The received subnet-scoped multicast packet is transmitted from one or more other interfaces of the forwarding device that are connected to one or more other host devices of the subnet. The received subnet-scoped multicast packet is also encapsulated with an additional header. The encapsulated subnet-scoped multicast packet is forwarded from the forwarding device to an intermediate router which routes the encapsulated subnet-scoped multicast packet to one or more other forwarding devices configured to decapsulate the encapsulated subnet-scoped multicast packet and transmit the decapsulated subnet-scoped multicast packet to one or more connected host devices of an additional portion of the subnet.

    Abstract: Techniques are provided to enable a support for guest access of devices in a network. At a controller apparatus in a first mobility sub-domain of a network comprising a plurality of mobility sub-domains, a request message containing a request for guest network access for a device is received from a first access switch in the first mobility sub-domain. The controller apparatus forwards the request message to a guest controller. At a tunneling endpoint apparatus in the first mobility sub-domain, a tunnel is established to the guest controller to carry traffic between the device and the guest controller. Traffic for the device passes in a tunnel between the first access switch and the tunneling endpoint apparatus in the first mobility sub-domain, through the tunneling endpoint apparatus in the first mobility sub-domain and in the tunnel between the routing apparatus in the first mobility sub-domain and the guest controller.
