Abstract:
An automatic configuration system maps a device address of each node coupled to a bus structure to a network protocol address corresponding to the physical location of the node. A configuration database is built which includes the network protocol address of each node and its corresponding device address. A wiring database, including each device position within the network, is maintained within a network server. Preferably, the network is an IEEE 1394 serial bus network. A topology map, including the device addresses of the nodes within the network and their relationship to each other, is generated during a self-ID sequence and is maintained by the network server. This information is then compared to the wiring database by the network server in order to build a restored topology map including the corresponding device address for each device at each position. A DHCP database is then generated which includes each device address and its corresponding network protocol address. The network protocol address corresponds to the position of the respective device.
