1394 - Method and system for generating multiple self-ID packets on the 1394 bus using a standard PHY chip

摘要

A method and system for generating a plurality of magnetic -ID packet that is used to map the node topology (node ​​topology) is described. The node topology, high-performance serial bus 11 and a plurality of nodes coupled to the serial bus (NOD1, NOD2, ..., NODn) based on a computer system consisting of a. Further it comprises identification packets that are used to identify - each node itself on the self network. In particular, during practice, a plurality of virtual node does not exist (VNOD1, ..., VNODn), as well as a plurality of magnetic -ID packets magnetic -ID process associated with the hardware that actually present on the bus 11, It is generated. Then, this magnetic -ID packets are sent to the other remaining node in the network via the serial bus to identify themselves. After that, the topology map tables from all the magnetic -ID packet is generated.
