Abstract
An ATM switch for providing an electrical interconnection between a connection-oriented ATM LAN of an ATM system and a connectionless legacy LAN is provided. The ATM switch includes a switch fabric electrically connected to the ATM LAN, a segmentation and reassembly block electrically connected to the switch fabric, for providing an interchange between one of cells transmitted over the ATM LAN and a packet transmitted over the legacy LAN, a management and control block electrically connected to the switch fabric through the segmentation and control block so as to manage and control operations for electrical connections between networks, a first bridging/routing processor having a legacy LAN interface for providing electrical connections between the legacy LAN and the first bridging/routing processor, a second bridging/routing processor electrically connected to the switch fabric through at least one ATM interface, and a bus for providing electrical connections between the management and control block, the first bridging/routing processor and the second bridging/routing processor. A LAN emulation configuration server function for managing configurations of a plurality of virtual LAN…
