Abstract
A method and system for improving communications in data communications networks which provide network emulation. The method and system accomplish their objects via communications equipment adapted to do the following: implant a number of distributed-redundant gateways in an emulated network; and dynamically assign access to operational distributed-redundant gateways. In one embodiment, the network emulation is an Asynchronous Transfer Mode Emulation Local Area Network (ATM ELAN), and the distributed-redundant gateways operate as default Internet Protocol (IP) gateway utilized by LAN Emulation Clients (LE Clients) of the ATM ELAN. Also in one embodiment, the dynamic assignment of access is done such that the data communications loading associated with the default IP gateway is distributed throughout a data communications network.
