Systems and methods for waking a fabric network of devices and communicating messages among the devices are described herein. An electronic device can communicate with other electronic devices of a fabric network broadcasting a wake message to the fabric network in response to an awakening event. The wake message can include a reason for triggering a wakeup of each device in the fabric network and a wake time signaling period. After the wake time signaling period lapses, a fabric message can be broadcasted to the fabric network, and the fabric message can be selectively rebroadcasted.

Apparatus and method for monitoring IP multicast delivery. One embodiment comprises an Optical Line Termination (OLT) device that includes a Network Termination (NT) device that connects to a core network, and a plurality of Line Termination (LT) devices that connect to an optical distribution network. The NT device generates an IP multicast monitoring stream directed to a group address, and transmits the monitoring stream to the LT devices. The LT devices then monitor for packets directed to the group address. When an LT device detects a loss of one or more packets directed to the group address, the LT device reports packet loss for the IP multicast monitoring stream to the NT device.

Examples disclosed herein relate to selecting an optimal network device for reporting flow table misses upon expiry of a flow in a software defined network, comprising. An SDN enabled device is selected, from a plurality of software defined network (SDN) enabled devices, for reporting a flow table miss upon expiry of a flow to an SDN controller, based on a pre-defined factor.

For a network with host machines that are hosting virtual machines, a method for facilitating BUM (broadcast, unknown unicast, and multicast) traffic between a hardware switch (e.g., ToR switch) and the host machines is provided. The network has a set of host machines configured as a cluster of replicators for replicating BUM traffic from the hardware switch to the host machines. A set of network controllers establishes failure-detection tunnels for links between the hardware switch and the replicator cluster. The replicator cluster informs the set of controllers of a change in the membership of the replicator cluster to initiate an update to the active failure-detection sessions. The set of network controllers communicates with the replicator cluster and a ToR switch to establish bidirectional forwarding detection (BFD) sessions between one or more replicator nodes in the replicator cluster and the ToR switch.

One or more techniques and/or systems are provided for multicast transport configuration, for multicast transport, and/or for fault policy implementation. In an example, a multicast component may receive a data copy request from an application to copy data to multiple destinations. A scheduler component may create a transport schedule specifying an order with which to facilitate data copy operations across transports, such as heterogeneous transports, to the destinations. A dispatcher component may apply application specified transport modifiers to the data copy operations (e.g., a modification to a quality of service for a transport). The dispatcher component may facilitate the data copy operations and provide operation result information to a policy agent. The policy agent may provide notifications of data copy operation statuses from the operation result information and/or may implement a fault policy (e.g., a retry on a different transport) for a data copy operation that experienced a fault.

A multimedia conferencing service uses accessible-forwarding-plane network elements such as OpenFlow® controllers and OpenFlow®-enabled switches. A conferencing server receives a conference subscription request including a network address of a L2/L3 signaling server, and connects to an accessible-forwarding-plane controller to control an accessible-forwarding-plane switch. Flow tables and group tables are managed to classify traffic with minimum table usage and update frequency. Media channels are established between clients through the OpenFlow®-enabled switches, relieving bottlenecks at the conferencing server.

Provided a proof of play (PoP) method of a digital signage terminal and a digital signage server, the PoP method of the digital signage terminal including obtaining a digital signature and a PoP message generation policy provided by a content owner, generating log data comprising information on a play of at least one piece of content, based on the PoP message generation policy, generating a PoP message using information on the digital signature based on the generated log data, and providing the PoP message to at least one of the digital signage server and the content owner.

A network node (120) initiates a multicast transmission of a data item via a cellular network to a plurality of devices (10). Associated with the multicast transmission, the network node (120) provides a request that at least a subgroup of the devices (10) each send a report indicating whether an action on the basis of the data item received by the device (10) was successfully completed by the device (10). Depending on the reports, the network node (120) adjusts the repeated multicast transmission of the data item.

Systems, methods, and instrumentalities are disclosed to determine access control and channel and signaling priority. A wireless transmit/receive unit (WTRU) may comprise a processor configured, at least in part, to determine device-to-device (D2D) data to be transmitted. The WTRU may determine if the D2D data may be transmitted. The WTRU may determine available scheduling assignment (SA) resources used for priority based D2D data signals. The WTRU may select one or more available SA resources used for priority based D2D data signals. The WTRU may transmit the D2D data, wherein the D2D data may be transmitted on the selected SA resources.

Advertisement systems may have an administration server, a broadcast system, a receiver, and a consumer device. The receiver may be configured to receive an advertisement with a call-to-action code. The receiver may also be configured to broadcast the advertisement with the call-to-action code to a consumer. The receiver may have an input mechanism. The consumer device may be in communication with the receiver and the administration server. The consumer device may be configured to receive the call-to-action code from the receiver when the consumer engages the input mechanism. The consumer device may include a software application. The software application may be configured to parse the call-to-action code with the administration server into call-to-action instructions. The software application may be further configured to permit the consumer to selectively integrate the call-to-action details into a third-party application on the consumer device.
