Abstract: A data link layer switch includes a switching mechanism coupled to a plurality of port interface controllers. Each of the port interface controllers comprises a multicast address table, a multicast matcher, and a timer. The multicast address table stores multicast addresses for hosts attached to the port interface controller. The multicast matcher matches an incoming packet to a target pattern, generates a multicast address from the incoming packet if the incoming packet matches the target pattern, and stores the generated multicast address in the multicast address table. The timer determines an amount of time that the generated multicast address remains in the multicast address table.

Abstract: A system and method for establishing voice communication between a packet-switched network and a circuit-switched network includes a network interface unit for coupling to the packet-switched network, a phone interface unit for coupling to the circuit-switched network and a gateway processor coupled to the network interface unit and to the phone interface unit. In response to a call request, a packet-switched network connection is established between the gateway processor and a first station in the packet-switched network, and a circuit-switched network-connection is established between the gateway processor and a second station in the circuit-switched network. Incoming voice data packets received from the first station are converted to outgoing voice signals, which are transmitted over the circuit-switched network connection to the second station. Incoming voice signals received from the second station are converted to outgoing voice data packets, which are transmitted over the packet-switched network connection to the first station. A conference call may be established among three or more conference call participants.

Abstract: A data communication network includes a network access unit for coupling one or more computer devices to the network. The network typically has asymmetric upstream and downstream data transmission rates. The network access device implements a method for acknowledging data packets. When a new packet is received by the network access unit from one of the computer devices, the new packet is placed in an outbound queue in the network access unit. When the new packet contains an acknowledgment, previous acknowledgment packets in the outbound queue that have the same source and destination addresses as the new packet are identified and discarded. Remaining packets are transmitted from the outbound queue in the network access unit. By discarding acknowledgment packets in the network access unit, throughput is increased.
