Address assignment in an ATM switched network
First Claim
1. A method for configuring a node in an ATM switched network including an ATM switch and an address server, the node and the address server being connected with the ATM switch, the method comprising the steps of:
- detecting at the address server a transition of the node from an inactive condition to an active condition;
selecting at the address server an ATM node address for the node in response to the detected transition;
transmitting the selected ATM node address from the address server to the one node via the ATM switch; and
initializing the node with the selected ATM node address.

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.

9. A method of configuring a link-interface unit in a signaling transfer point, the link-interface unit being part of an ATM switched network, including an ATM switch and an address server, having a source address in the ATM switched network, the method comprising the steps of:
-
transitioning the link-interface unit from an inactive to an active condition; detecting, at the ATM switch, the active condition and transmitting a link-active signal to the address server in response to the detected active condition; receiving, at the address server, the link-active signal from the ATM switch; transmitting, in response to the receipt of the link-active signal, the source address and a link address back to the link-interface unit via the ATM switch, the link address designating an address for the link-interface unit within the ATM switched network; and initializing the link-interface unit with the link address and the source address. - View Dependent Claims (10, 11, 12)

13. An ATM switched network, comprising:
-
a plurality of nodes; an ATM switch, coupled to the nodes, for multiplexing and switching ATM cells received on virtual connections, the ATM switch including means for determining when a first one of the nodes changes from an inactive to an active condition; and an address server connected to the ATM switch and including means for determining from the ATM switch that the first node has transitioned and means for providing to the first node the ATM node address and configuration data to initialize communication interfaces between the first node and others of the plurality of nodes in the ATM switched network. - View Dependent Claims (14, 15, 16)

17. A method for booting an ATM switched network, including an ATM switch, a plurality of nodes, and one address server including a non-volatile storage device for storing operating system data for the address server, the ATM switch, and the plurality of nodes, the method comprising the steps of:
-
reading, by the address server, address server operating system data from the non-volatile storage device and configuring the address server in the ATM switched network; reading, by the ATM switch, ATM switch operating system data from the non-volatile storage device and configuring the ATM switch to build virtual connections to the nodes in the ATM switched network; sending a respective ATM node address from the address server to each of the nodes; downloading node operating system data from the address server to each of the nodes; and initializing, at each of the nodes, communication interfaces with others of the nodes in the ATM switched network. - View Dependent Claims (18, 19, 20)
