Abstract
A method of providing self-sustained even arbitration within an IEEE 1394-1995 serial bus network of devices controls the arbitration and assignment of newly-connected simpler devices to more complex devices within a network of devices. A priority arbitration formula is preferably used to determine the more complex device within a network of devices which will take assignment of a newly-connected simpler device. Alternatively, a delay time arbitration formula is used to determine the more complex device within the network of devices which will take assignment of a newly-connected simpler device. Using either the priority arbitration formula or the delay time arbitration formula, a more complex device with the lowest number of currently assigned simpler devices is assigned a newly-connected simpler device. If more than one of the more complex devices have an equal number of assigned simpler devices which is the lowest number of currently assigned simpler devices, then the address value of the more complex devices determines which one of the more complex devices with the lowest number of currently assigned simpler devices will take assignment of a newly-connected simpler device.
