摘要： A method of alleviating network congestion in an emulated Local Area Network (ELAN) within an Asynchronous Transfer Mode (ATM) network is implemented. The method mitigates network congestion by distributing the connection times of Local Area Network (LAN) Emulation Client (LEC) to an ELAN over random periods of time. When a LAN Emulation Server (LES) or Broadcast and Unknown Server (BUS) attempts to build point-to-multipoint connections to the LEC, it issues control messages to network switches. If the messages are dropped or rejected the LES or BUS recognizes the network is in a congested state and randomly retries to attempt connection.

摘要： An ATM communications network with several ELANs allows steady-state data to be passed between ATM attached devices which bypasses intermediate LECs and bridges. Connected to the ATM communications network is a bridge unit which includes a bridge and associated LECs. Also, an origination ATM attached device and a destination ATM attached device are attached to the ATM communications network via a first by a first ELAN and a second ELAN, respectively. The origination ATM attached device sends a request for an ATM address associated with the destination ATM attached device to the bridge, via the first ELAN. After some processing, the bridge returns the ATM address associated with the destination ATM attached device to the origination ATM attached device. This allows the origination ATM attached device to establish a shortcut VCC with the destination ATM attached device using the ATM address associated with the destination ATM attached device, thereby bypassing intermediate bridges and LECs.

摘要： Provided are a method and system for achieving enhanced performance in communications between a plurality of emulated networks overlaid onto at least one base network, wherein the communications involve one or more source route bridges. The method and system accomplish their objects via the following. Determining when communication is to occur, through the one or more source route bridges, and between at least two entities where a first of the at least two entities is a member of a first emulated network and where a second of the at least two entities is a member of another of the plurality of emulated networks. Informing the at least one of the at least two entities of one or more addresses consonant with the protocols of the at least one base network wherein the one or more addresses identify one or more base network entities closely correspondent to at least one of the at least two entities. And thereafter utilizing the one or more addresses in communication between the first and second entities such that communications between the first and second entities is established in such a fashion that at least one of the one or more source route bridges is bypassed, thereby ensuring that the processing and delay associated with the at least one bypassed source route bridge is avoided wherein the performance in communications involving the at least two emulated networks is enhanced.

摘要： An ELAN having redundant default gateways is attached to an asynchronous transfer mode (ATM) communications network. The ELAN's redundant default gateways are comprised of a first and second routers. The first router is associated with a primary default gateway and the second router is associated with a backup default gateway. Both the primary and backup default gateways are connected to the ELAN and both the primary and backup default gateways are configured with a default gateway IP address and associated MAC address. Initially, the primary default gateway registers the default gateway MAC address, thereby becoming the active default gateway. While the primary default gateway is active, the backup default gateway continually attempts to register the default gateway MAC address. When the primary default gateway fails, the backup default gateway will be able to successfully register the default gateway MAC address and take over the responsibilities of the primary default gateway and become the active default gateway.

摘要： A method is implemented to enable networks employing source-route bridging to participate in route switched, Asynchronous Transfer Mode (ATM), networks. Such source-routed networks, for example, Token-Ring LANs, incorporate an end-to-end route description in the data packets transmitted by the source station. The end-to-end route description is contained in a Route Information Field (RIF). The method implemented herein associates an RIF with the ATM address corresponding to a destination station. This permits the source-route bridged network to exploit the efficiencies of layer-2 connections and the high-speed switching characteristics of the ATM network.
