Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Provided are a method and system for use within at least one network wherein broadcast occurs. The method and system achieve their objects as follows. In response to reception of a data frame with at least one destination indicator ordinarily requiring broadcast to a first defined group of stations, at least one attribute of the received data frame is examined. In response to the step of examining, the received data frame is transmitted to a defined second group of stations, smaller in number than the first group of stations.

Abstract: Provided are a method and system that allow one or more network protocol emulators, composed of one or more network protocol emulation controllers and one or more network protocol emulation entities, which are overlaid onto the one or more base networks utilizing different communications protocols for the purpose of allowing said one or more networks to be accessed and utilized as if the one or more networks were utilizing protocols emulated by the one or more network protocol emulators. The method and system utilize the following steps. Apprising the one or more network protocol emulation controllers of network capability information inherent within protocols utilized by the one or more networks onto which the one or more network protocol emulation controllers are overlaid.
