ABSTRACT:
A combination of a standardized high speed switch interconnect scheme and global management makes a stack of multiple switches appear as one large managed high speed switch without impeding the transmission of information between individual switches within the managed switch, thereby providing a high speed connection between networking devices. Standard two port PCI bridges are interconnected such that an apparent three port bridge is created. This allows a transaction between systems to occur without interrupting intermediate systems. By logically connecting the PCI bus of one system to that of another, a processor in one system is allowed to access all devices in all the systems that are connected in the stack. In this way only one processor or management entity is required to configure and control a group of stacked systems.
