1. A method for managing transactions between a Peripheral Component Interconnect Express (PCIe) host connected to a first interconnect fabric and a PCIe endpoint connected to a second interconnect fabric, wherein the first interconnect fabric are remotely and communicably connected to each other over a communication network, the method comprising:

  • receiving a communication at the first interconnect fabric from the second interconnect fabric indicating that the PCIe endpoints is discovered on a PCIe bus of the second interconnect fabric;

    connecting the PCIe endpoint to a root complex interface of the second interconnect fabric;

    providing a virtual network interface card (vNIC) having a local address, wherein the local address is used to address the PCIe endpoint at the root complex interface of the second interconnect fabric;

    associating the PCIe host with the PCIe endpoint in a virtual topology, wherein the virtual topology comprises a virtual address for the PCIe endpoint; and

    providing a mapping for translating between the virtual address and the local address.
