Abstract

A system and method are disclosed for a flexible routing engine in a PCIe switch. The system may include a switch manager that is enabled, through firmware, to configure one or more routing tables associated with a switch stack of a PCIe switch. To enable non-transparent bridging and non-standard routing, such as mapped I/O routing, the method may include receiving a transaction layer packet at a mapped I/O routed port of a PCIe switch, and performing translation of the requester ID of the packet utilizing tables that are updated by the firmware of the switch manager to route the packet through the switch.
