Abstract: A wireless earphone system (1) comprising a first earphone (2) and a second earphone (3). The first earphone (2) comprises a first earphone transceiver (6) of a first type and a second earphone transceiver (7) of a second type, and the second earphone (3) comprises a third earphone transceiver (7) of the first type. A first wireless link (5) can be established between the first earphone transceiver (6) and the third earphone transceiver (8), and a second wireless link (9) can be established between the second earphone transceiver (7) and an audio rendering transceiver (25) of the second type of an audio rendering device (4). The first earphone device (2) is adapted to send a link status signal (12) via the second wireless link (9) to the audio rendering device (4).

Abstract: An improved method and apparatus to retrieve information over a network is described.

Abstract: A method and apparatus to provide redundancy in a network is described.

Abstract: Simple network management protocol or SNMP is encapsulated into HTTP traffic. The HTTP traffic is in a form that allows it to pass through a firewall. At one end, and SNMP request is encapsulated and sent to a remote computer. The remote computer de-encapsulates the request and responds to the SNMP request. The SNMP response is encapsulated as an HTTP response, and sent to the management station which interprets the results.

Abstract: A system and method of transmitting data frames between media access control (MAC) devices through a mesh of data switches is disclosed. Each of the data switches maps each MAC device to a port or aggregation of ports on the data switch for transmitting data frames having a destination associated with the MAC device. Upon receipt of a data frame from a previously undiscovered MAC device at a first data switch, the first data switch informs the other data switches of the undiscovered MAC device. This permits each of the other data switches to map the undiscovered MAC device with a port or aggregation of ports mapped to the first data switch. The other data switches may then transmit subsequent data frames having a destination associated with the previously undiscovered MAC device through a port or aggregation of ports mapped to the first data switch.
