Abstract
An ATM switched network has an ATM switch, an address server, and a plurality of nodes connected through virtual connections established by the ATM switch. When a node fails and is replaced, the ATM switch recognizes the installation of the node and notifies the address server. The address server selects an ATM address for the replacement node and sends the ATM address and an Internet Protocol (IP) address to the node. The node responds by requesting configuration data, which the address server downloads to the node. Thereafter, the node may initialize its communication interfaces within the ATM network. The address server also assigns ATM and IP addresses to network nodes following power-up of the network. Nodes are assigned an ATM address and an IP address by the address server, thereby eliminating the need to configure nodes with addressing information during manufacture or installation.
