    摘要： A method for providing redundancy to an Asynchronous Transfer Mode (ATM) emulated local-area network (LAN) is disclosed. The ATM emulated LAN is served by a primary LAN Emulation Server, a Broadcast and Unknown Server (LES/BUS), and a LAN Emulation Configuration Server (LECS). A backup LES/BUS is coupled to the ATM emulated LAN. A logical redundancy virtual channel connection (VCC) is then established between the primary LES/BUS and the backup LES/BUS. When the redundancy VCC is present between the primary LES/BUS and the backup LES/BUS, the backup LES/BUS is placed in a dormant mode. However, when the redundancy VCC is absence between the primary LES/BUS and the backup LES/BUS, the backup LES/BUS is activated to serve any request generated by the ATM emulated LAN.

    摘要： A method for providing a security mechanism to an Asynchronous Transfer Mode (ATM) emulated local-area network (LAN) is disclosed. The ATM emulated LAN is served by a LAN Emulation Server (LES), a Broadcast and Unknown Server (BUS), and a LAN Emulation Configuration Server (LECS). After receiving a LE_JOIN_REQUEST from an LE client within the emulated LAN, the LES forms a LE_CONFIGURE_REQUEST on behalf of the LE client, by utilizing the information from the LE_JOIN_REQUEST. The LES then sends the LE_CONFIGURE_REQUEST to the LECS. In turn, the LECS sends back a LE_CONFIGURE_RESPONSE to the LES. After receiving the LE_CONFIGURE_RESPONSE from the LECS, a determination is made as to whether or not a status field within the LE_CONFIGURE_RESPONSE indicates a success and a target ATM address field within the LE_CONFIGURE_RESPONSE contains an ATM address of the LES. If both of the above-mentioned conditions are met, the LES then sends a LE_JOIN_RESPONSE with a success status back to the requesting LE client such that the requesting LE client is allowed to join the emulated LAN.

    摘要： An apparatus comprising a network interface coupled to a data network, a network address translator and a controller. The network interface may receive network traffic from the communicatively coupled data network adhering to any of a number of alternative network protocols. The network address translator identifies network session information within the received network traffic adhering to any of a number of alternative protocols. The controller selects network traffic to be cached based, at least in part, on the network session information identified by the network address translator.

    摘要： An aggregation device that connects a plurality of internal sub-networks processes a packet that is destined for one of the plurality of sub-networks. The aggregation device receives the packet and determines an internal sub-network identification value based on the combination of an external sub-network identification value that is in the packet, and a port of the aggregation device to which the one of the plurality of internal sub-networks is connected. The aggregation device may also determine an external sub-network identification value based on an internal sub-network identification value that is associated with a port of the aggregation device to which one of the plurality of internal sub-networks is connected. The external sub-network identification value is stored in the packet and the packet is transmitted on the port of the aggregation device to which the one of the plurality of internal sub-networks is connected.

    摘要： A method of remotely configuring a network device requires the generation of configuration information for the network device at a central configuration server, which is located remotely from the network device on a network. The configuration information includes a device configuration parameter. On receipt of identification information concerning the network device at the central configuration server, the central configuration server propagates the configuration information to the network device.
