  • Patent number: 8787373
    Abstract: Techniques are provided for multicast miss notification for a distributed network switch. In one embodiment, a bridge element in the distributed network switch receives a frame destined for a multicast group on a network. If a local multicast forwarding table of the bridge element does not include any forwarding entry for the multicast group, a forwarding entry is selected from the local multicast forwarding table as a candidate for being replaced. An indication of the candidate is sent to a management controller in the distributed network switch.

  • Patent number: 8787205
    Abstract: A system and method for multicast transmission are disclosed. In one embodiment, a virtual exchange network including interconnected nodes is embedded within a network. A sender is disposed in communication with a root node and receivers are disposed in communication with a set of edge nodes. The sender publishes a packetized data stream to which the receivers subscribe. The packetized data stream is promulgated by implicit signaling through optimum virtual exchange network connections from the sender through the virtual exchange network to the receivers. The interconnected nodes, responsive to receiving the published packetized data stream, are adapted to multicast N instances of the published packetized data stream to N recipients selected from the group consisting of receivers and other of the interconnected nodes.

  • Patent number: 8787154
    Abstract: In general, techniques are described for dynamically scheduling and establishing paths in a multi-layer, multi-topology network to provide dynamic network resource allocation and support packet flow steering along paths prescribed at any layer or combination of layers of the network. In one example, a multi-topology path computation element (PCE) accepts requests from client applications for dedicated paths. The PCE receives topology information from network devices and attempts to identify paths through a layer or combination of layers of the network that can be established at the requested time in view of the specifications requested for the dedicated paths and the anticipated bandwidth/capacity available in the network. The PCE schedules the identified paths through the one or more layers of the network to carry traffic for the requested paths. At the scheduled times, the PCE programs path forwarding information into network nodes to establish the scheduled paths.

  • Patent number: 8780836
    Abstract: A switch transfers a predetermined packet to an appliance. The appliance generates a rewritten packet by carrying out the packet header rewriting on the predetermined packet and forwards the rewritten packet back to the switch. The switch transfers the rewritten packet received from the appliance to a controller. In a case when the rewritten packet meets a predetermined condition, the controller generates entry setting data which instructs to set a new entry on the basis of a destination of the rewritten packet and the predetermined rewriting mode, and sends the entry setting data to the switch. The new entry indicates that packets belonging to the same flow as the predetermined packet are transferred to the destination without being routed through the appliance. The switch adds the new entry to the flow table in accordance with the entry setting data received from the controller.

  • Patent number: 8780749
    Abstract: A method and apparatus for estimating a signal-to-interference ratio (SIR) are disclosed. A received signal includes signal energy on multiple basis functions. Desired signal energy in the received signal is transformed onto a first basis function with constant polarity. The desired signal energy is estimated by coherently averaging signal energy on the first basis function. A noise power is estimated by averaging signal energy on each basis function other than the first basis function and accumulating the averaged signal energy from the basis function other than the first basis function and scaling the accumulated signal energy to account for a noise estimate from the first basis function. An SIR is estimated by dividing the desired signal energy by the noise power.

  • Patent number: 8780783
    Abstract: Teachings herein include a base station for propagating system information changes from the base station to the relay node. Upon transmitting system information changes to the relay node, the base station defers data transmission between the base station and the relay node until a set time period. In many embodiments, the base station is configured to actually apply the system information changes during this time period, while the relay node applies the changes before then, e.g., by applying them immediately upon reception. The base station's deferral of data transmission until the set time period thus ensures that data transmission does not occur until both the base station and the relay node have applied the pending changes. This in turn prevents radio link failure from occurring due to use of different system parameters by the base station and relay node.
