  • Patent number: 7787436
    Abstract: An access point of a communications network is configured to receive a multicast or broadcast packet from a source. The access point converts the multicast or broadcast packet into a unicast packet addressed to a station associated with the access point. The access point then transmits the unicast packet over the communications network from the access point to the station. The access point further may determine a minimum data rate by which the access point may transmit the multicast or broadcast packet to the station and determines an effective unicast rate for transmitting the unicast packet to the station. If the effective unicast rate does not exceed the minimum data rate, the access point does not transmit the unicast packet to the station and transmits the multicast or broadcast packet.
    Type: Grant

  • Publication number: 20040001433
    Abstract: Methods and apparatus are disclosed for establishing interfaces or “tunnels” between networking devices, so one device can control the other and vice versa. Such devices may be general purpose processors (GPP) and ethernet web switches. A first device receives data packets as they flow across a network. A second device can access packets only if they flow through the first device. The second device can only send packets to the network if they flow through the first device. In a preferred embodiment, the first device is optimized for high-speed data transfer and the second device for data inspection and flow decision making. Each tunnel carries related types of packets in one direction between “partnered” devices. Data tunnels pass network data packets. Control tunnels carry messages to control the operation of a first device by a second. Messages stop, start or otherwise direct the flow of data through the first device. A Broadcast tunnel enables several network devices to interact.
