PROBLEM TO BE SOLVED: To provide sufficient hardware and/or software to enable two systems to interface to enable two independent systems.SOLUTION: A PCIe Fabric 100 includes IO tier switches 108A, 108B, hub tier switches 106A, 106B, and a target device. The IO tier switches are configured to receive a TLP from a client and, based on a determination that an address in the TLP is not associated with any multicast address range in the first IO tier switch and is not associated with any downstream port in the first IO tier switch, route the TLP to the first hub tier switch via an upstream port on the IO tier switch. The hub tier switch is configured to, based on a determination that the TLP is associated with a multicast group, generate a rewritten TLP and route it to the target device via a downstream port on the hub tier switch. |
