Abstract
A method and device for identifying that a 1394a node is actively attached to a 1394b network and indicating so to the 1394b network. In one embodiment, a border node first determines that a 1394a node is actively attached to the border node. Then, the border node sets a reserved bit in a self-identification packet, indicating the active presence of the 1394a node. Then, during the self-identification process, the border node transmits the self-identification packet into a 1394b network, indicating to all 1394b nodes in the 1394b network that there is a border node with an active connection to a 1394a node. Next, the 1394b nodes in the 1394b network of compliant devices alter their behavior for arbitration purposes, such that an 1394a network and a 1394b network may share a communication link.
