Abstract:
A method for configuring an IEEE 1394 network composed of a plurality of IEEE 1394 buses joined by at least one IEEE 1394 bridge having at least two portals, each of the portals having a single IEEE 1394 bus connected thereto, comprising the steps of:a) configuring each of the IEEE 1394 buses according to IEEE 1394 standard with each node including a node identification comprising a first part storing a bus identification indicating a non-configured bus and a second part storing a physcal identification; b) selecting a network management node from a first IEEE 1394 bus including at least one node capable of network management; c) configuring the first IEEE 1394 bus into a configured IEEE bus such that the first IEEE 1394 bus belongs to the network management node with the node identification of each node connected to the first IEEE 1394 bus including in the first part a bus identification indicating the first IEEE 1394 bus, each of the nodes of buses other than the first IEEE 1394 bus continuing to have the bus identification indicating a non-configured bus; d) upon completion of configuring the first IEEE 1394 bus, configuring an adjacent IEEE 1394 bus of the fist IEEE 1394 bus into a configured IEEE 1394 bus to produce an interim network such that the adjacent IEEE 1394 bus belongs to the network management node with the node identification of each node connected to the adjacent IEEE 1394 bus including in the first part a bus identification indicating the adjacent IEEE 1394 bus, each of the nodes of buses other than the first IEEE 1394 bus and the adjacent IEEE 1394 bus continuing to have the bus identification indicating a non-configured bus; and e) upon completing step d), repeating the step d) until no adjacent IEEE 1394 bus which does not belong to the network management node is left in the IEEE 1394 network and the first part of each node identification within the IEEE 1394 network is free of the common bus identification indicating a non-configured bus.
