Address Routing and Path Routing

There are two ways to interconnect StarFabric-enabled devices:

• Address Routing

• Path Routing

Address Routing Application

Address routing is the PCI-to-PCI bridge method similar to a typical legacy PCI

environment. This is the mode the PCI-SB card operates in by default. All the Star-

Fabric-enabled devices in the fabric appear as standard PCI bridges with a numeric

fabric identification (FID) number, creating a standard PCI bridge topology without

switching behavior or redundant, bundled links to other PCI bridges or expansion

devices.

This application provides a simple, cost-effective migration from a hierarchical leg-

acy PCI topology to the next-generation StarFabric solution that can be used out of

the box without developing custom software.

At power-up, all the StarFabric-enabled devices are discovered and identified by

FID, and the fabric remains static despite physical changes in the topology. If a link

to a device goes down or a device becomes disabled, the device is unavailable to

the fabric and there is no automatic or dynamic reconfiguration of the PCI bridge

topology, as shown in Figure 11.
