Abstract: A method of maintaining communications in a bus bridge interconnect including a plurality of buses linked by at least one bus bridge. The method includes receiving a change indication signal from a talker node, performing an address resolution protocol in response to the change indication signal to find an updated node identification address(“nodeID”) for a listener node using a extended unique identifier (“EUI”) of the listener node, and storing the updated listener nodeID with the listener node EUI.

Abstract: A method and system for quarantine during bus topology configuration are described. In one embodiment, the invention is a method. The method includes quarantining a set of devices coupled to a bus. The method further includes establishing a topology of the bus. The method may also include receiving a reset signal and quarantining in response to the reset signal. In an alternate embodiment, the invention is a system. The system includes a bus having a reset signal and a plurality of data signals. The system also includes a set of devices, with each device of the set of devices coupled to the bus. The system further includes a controller. The controller having a memory configured to store device identifiers corresponding to the devices of the set of devices. The memory further configured to store quarantine information relating to the devices of the set of devices.
