Abstract
A method and system for using a new bus identifier in an interconnect, and the interconnect including a plurality of nodes and at least one bus bridge. A configuration change is determined on the first bus connected to the plurality of nodes. Each node has a corresponding bus identifier. A new bus identifier is assigned for each node having a changed state if a configuration change is determined on the first bus.

A method for using a new bus identifier in an interconnect, the interconnect having a plurality of nodes connected to multiple busses and at least one bus bridge, the method comprising:
- determining a configuration change on any of the busses connected to the plurality of nodes, each node having a corresponding bus identifier;
- and
- assigning, by the at least one bus bridge, a new bus identifier for each node having a changed state if the node is currently connected to a bus affected by the configuration change is.
An interconnect system, comprising:
- a plurality of busses;
- at least one bus bridge;
- and
- a plurality of nodes connected to the plurality of busses, each node having a corresponding bus identifier and configured to be assigned a new bus identifier, wherein the at least one bus bridge is configured to assign the new bus identifier to each node having a change of state if the node is currently connected to a bus affected by a configuration change on any of the busses.
An apparatus comprising:
- means for connecting a device to a bus, said means for connecting the device to a bus being configured to be assigned a new bus identifier;
- and
- means for interconnecting a plurality of busses, said means for interconnecting a plurality of busses being configured to assign the new bus identifier to each means for connecting having a change of state if the means for connecting is currently connected to a bus affected by a configuration change on any of the busses.
