  • Patent number: 8547844
    Abstract: A method and system are disclosed for distributing load in a network. A set of routers are configured for providing IP gateway services to a set of hosts where each router in the set of routers all back up all the other routers in the same set. Each router in the set utilizes identical load distribution policies, load distribution properties and load distribution arrangement. A Load Distribution Function (LDF) master router is determined for the set of routers, wherein each one of the set of routers is a backup for the LDF master router. Every router in the set of routers utilize the same algorithm to compute load distribution and the LDF master router provides balancing information to all the other routers by including that information in VRRP advertisement messages to all the routers.

  • Patent number: 7835727
    Abstract: An application that runs on a User Equipment (UE) in one of three main modes: (1) listener, (2) proxy, or (3) controller, and defaults to listener mode. A UE is placed by a user into controller mode, which causes the application to scan the area covered by its Bluetooth radio and identify other Bluetooth enabled devices. For all the Bluetooth devices found, the controller attempts to contact the UEs in listener mode to form a group of interested listeners. The UE in controller mode then sends a message to all group members. The message alerts the user of each UE in listening mode to prepare to take a photograph or video. The UE in listener mode provides the users with audio and visual cues and after a time period each UE in the group takes a photograph or a video.

  • Patent number: 7756125
    Abstract: A destination router label is added to Pseudo Wire encapsulated data packets for crossing a Multiple Protocol Label Switching (MPLS) network. Data arrives at a PW function, which performs PW encapsulation, further adding a PWE control word and a PWE label. The PW function also adds a destination router label (DRL). The DRL is configured at PW creation time with a PW control message (that is, an unsolicited LabelMap message) to a specific edge router. The packet may then be sent to a Traffic Engineering (TE) function, which uses the DRL to make the routing decision for the packet. The routing decision includes adding a PSN tunnel label to replace the DRL label for crossing the transport network. The rest of the processing is conventional PWE3 transport on MPLS; that is, when the packet is received at a second PW function, it removes the PW encapsulations and forwards the packet based on the contents of the PWE label.

  • Publication number: 20080176514
    Abstract: An application that runs on a User Equipment (UE) in one of three main modes: (1) listener, (2) proxy, or (3) controller, and defaults to listener mode. A UE is adapted to be placed by a user into controller mode, which causes the application to scan the area covered by its Bluetooth radio and identify other Bluetooth enabled devices. For all the Bluetooth devices found, the controller attempts to contact the UEs in listener mode to form a group of interested listeners. The UE in controller mode then sends a message to all group members. The message alerts the user of each UE in listening mode to prepare to take a photograph or video. The UE in listener mode provides the users with audio and visual cues and after a time period each UE in the group takes a photograph or a video. The result is a set of photographs or videos taken at the same time in a related place but with differing points of view.

  • Publication number: 20070127479
    Abstract: The signaling for establishing a Pseudo Wire (PW) that crosses a Multiple Protocol Label Switching (MPLS) network is augmented to permit decoupling the PW processing and encapsulation from a Provider Edge (PE) or Customer Edge (CE) router. Configuration of a PW triggers the augmented PW signaling that traverses from the destination PW processing function to the origin PW processing function. The signaling may use Traffic Engineering (TE) tunnels set up a priori and, in the upstream CEs (or PEs) uses the embedded PW origin IP address to make routing decisions for the signaling packet. The rest of the signaling processing is conventional PWE3 signaling on MPLS.
