摘要：A method and system for improving communications in data communicationsnetworks which provide network emulation. The method and system accomplish theirobjects via communications equipment adapted to do the following: implant a number ofdistributed-redundant gateways in an emulated network; and dynamically assign accessto 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 oneembodiment, the dynamic assignment of access is done such that the data

communications loading associated with the default IP gateway is distributed throughouta data communications network.
