  • Establishing and maintaining master and standby LAN emulation server connections to provide a fault tolerant ELAN
    Patent number: 6701448
    Abstract: A system and method are disclosed for transferring an enhanced LAN Emulation Client from a first LAN Emulation Server to a second LAN Emulation Server. The addresses of the first LES and the second LES are determined at an LECS. The first LES and the second LES are connected to the LECS. The addresses of the first LES and the second LES are sent to the enhanced LEC so that the addresses of the first LES and the second LES may be stored at the enhanced LEC. When the enhanced LEC determines that the first LES has failed, the address of the second LES is looked up at the enhanced LEC and the enhanced LEC connects to the second LES.

  • Fault tolerant lane system
    Patent number: 5835481
    Abstract: A system and method are disclosed for providing a redundancy scheme in an ATM network providing a LAN emulation. The ATM network includes a set of LAN Emulation Connection Servers (LECS's) which connect with each other to determine which servers are operational and to automatically select an operational master LECS. The master LECS maintains a back end verification circuit with a set of operational LAN Emulation Servers (LES's), determines which operational LES will be the master LES, and directs LAN Emulation Clients (LEC's) to that LES. LEC's which lose their LES connection are directed to the proper LECS by a table stored in the ATM switch.
