A method and apparatus for routing multicast data across multiple multicast routing domains connected by a shortest path bridging (SPB) network is presented. A Shortest Path Bridging (SPB) edge router of an SPB network connected to a PIM network is configured as a Rendez vous Point (RP). A message is received at the RP, and in response, the RP forms a first structure including multicast sender information. The RP floods the SPB network with a second message containing the first data structure, allocates an Identifier (ISID) to the multicast stream, and sends a second data structure with sender information. An edge router with multicast receive interest responds with the second data structure with multicast receive interest information. As a result, a receiver in a second network has knowledge of devices in a first network such that multicast traffic is able to be routed between different networks connected to the SPB network.

The middleware presented herein maps a plurality of application user interfaces to a single user experience (i.e. user interface) so that a user is more comfortable with how information is presented. The middleware maps key elements of an original user interface into a standard user interface on a user's device. When a user interface is mapped, information or data is taken from the original user interface and is reconfigured to create the standard user interface displayed to the user. In embodiments, the middleware receives data associated with a user interface for an application, interprets the received data, parses the data, translates the parsed data by determining the correct template map and mapping the parsed data to a standard user interface, and configures the standard user interface with the translated data.

Systems, methods, and media for identifying and associating user devices with media cues are provided. In some embodiments, a plurality of data streams from a plurality of endpoints is received. At least one media segment is then received from a user device. It is determined whether the at least one media segment from the user device corresponds with one of the plurality of data streams from the plurality of endpoints. In response to being unable to match the at least one media segment, a media cue is inserted into one of the plurality of data streams. In response to detecting that the media cue in that data stream is received by the user device, identification information is transmitted to the user device that associates the user device with one or more services on a communications server.

A distributed system of appliances that comprises a centralized energy-use controller to coordinate the use of energy among a plurality of distributed and interconnected appliances is disclosed. For example, the centralized controller directs when each appliance refrains from using energy from its energy-storage device during intervals when the energy-storage device is capable of providing energy to the appliance but the centralized power supply is not, and when each appliance can consume energy from its energy-storage device during intervals when both the energy-storage device and the centralized power supply are capable of providing power to the appliance.

Methods and systems for identifying specified phrases within audio streams are provided. More particularly, a phrase is specified. An audio stream is them monitored for the phrase. In response to determining that the audio stream contains the phrase, verification from a user that the phrase was in fact included in the audio stream is requested. If such verification is received, the portion of the audio stream including the phrase is recorded. The recorded phrase can then be applied to identify future instances of the phrase in monitored audio streams.

Disclosed herein are systems, methods, and non-transitory computer-readable storage media for implementing real-time transport control protocol to obtain an end-to-end encryption and security status of a communication session. The system collects real-time transport control protocol messages associated with a communication session, wherein the real-time transport control protocol messages are generated by devices in the communication session, and wherein the real-time transport control protocol messages include security information associated with the communication session. Then, based on the real-time transport control protocol messages, the system determines a security status associated with the communication session. The system can also generate an indication of the security status associated with the communication session. Further, the system can generate an indication of the security status of a communication session on a per participant basis.

A method, apparatus and computer program product for imposing random delays for avoiding hidden terminal collisions in wireless mesh networks is presented. A packet is forwarded from a first node to a second node along a multihop path to a destination node. The second node refrains from forwarding the packet to a next hop of the multihop path for a predetermined delay time period. The packet is then forwarded after the predetermined delay time period by the second node to the next hop of the multihop path.

Techniques disclosed herein include systems and methods that extend Protocol Independent Multicast (PIM) protocols to Shortest Path Bridging (SPB) technology. This includes connecting an IP multicast domain across an SPB network. SPB edge routers, also known as Backbone Edge Bridges, form virtual adjacencies with each other. As such, SPB edge routers maintain such PIM adjacency without sending Hello messages. Backbone Edge Bridges (BEBs) are discovered using null Intermediate System To Intermediate System (IS-IS) Internet Protocol Multicast (IPMC) type-length-value (TLV) control messages. Each PIM-enabled BEB records other PIM-enabled BEBs as an adjacent PIM-router in response to receiving a NULL IPMC TLV from those BEBs. Accordingly, PIM-enabled BEBs form a full mesh virtual adjacency between each other and can thereby encapsulate PIM control messages sent and received between two access networks connected to the SPB network.
