Abstract
A method and interface system for hosting a logical address based network protocol suite on a high speed serial bus network which has operatively connected thereto a plurality of network devices, each defining a node with a dynamically variable physical address. The system includes a software interface for monitoring the network to identify the occurrence of a bus reset event which has the potential to change a physical address assigned to the nodes; for receiving an updated physical address provided by the network devices as a result of the bus reset event; computer memory for storing therein an updated physical address together with a corresponding device logical address in an address resolution table. The address resolution table provides a mapping between the physical address and the logical address assigned to each of the devices on the network. The interface accesses the address resolution table upon receipt of a data packet to be transmitted to determine an updated physical address for one of the devices based upon its logical address.
