Abstract
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.
