    Abstract: Techniques are provided to facilitate monitoring of utility application traffic streams. At a network device that routes utility application traffic for utility devices, control information is received, where the control information is configured to cause the network device to monitor utility application traffic that passes through the network device. The network device monitors a header inserted into utility application traffic messages based on the control information.

    Abstract: Presented herein are techniques useful in a network comprising a plurality of network nodes each configured to apply one or more service functions to traffic that passes through the respective network nodes. A network node receives packets encapsulated in a service header that includes information defining a variable set of context headers stacked into an association of metadata that is relevant to one or more service functions within a service path comprised of one or more network nodes. The network node interprets a forwarding state and a next-hop network node for the service path from the service header, and determines a service action or associated metadata from the set of context headers.

    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: Disclosed herein are methods of forwarding data over an IP network. The methods may include receiving a packet from a source host connected to the IP network, identifying the IP address of a destination host designated in the packet, determining the location on the IP network where the destination host designated by the packet is connected, without reference to the MAC address specified in the packet, by using location-identification information stored on the IP network, and forwarding the packet to the location on the IP network where the destination host is connected without reference to the MAC address specified in the packet. Also disclosed herein are related network devices implementing such techniques and operations, as well as IP networks which include such network devices.

    Abstract: An administrator can define or modify one or more service graphs. Next, the administrator can register service appliances along with their device package files with a controller. Then, the controller can establish the capabilities of the service devices, and classify the service devices as legacy or service tag switching (STS) capable devices. Then, the controller can create one or more instances of the service graph, by populating the service nodes into the service graph. Then, the application owner can attach their endpoint groups (EPGs) to the service graphs created by the administrator. Then, a service in the network can be automatically provisioned using the service graph to configure one or more nodes in an associated service chain of the service according to information in the service graph.

    Abstract: According to one embodiment, techniques are provided to enable secure communication among devices in a mesh network using a group temporal key. An authenticator device associated with a mesh network stores a pairwise master key for each of a plurality of devices in a mesh network upon authentication of the respective devices. Using the pairwise master key, the authenticator device initiates a handshake procedure with a particular device in the mesh network to mutually derive a pairwise temporal key from the pairwise master key. The authenticator device encrypts and signs a group temporal key using the pairwise temporal key for the particular device and sends the group temporal key encrypted and signed with the pairwise temporal key to the particular device.
