Abstract

Embodiments of the present invention provide a solution for managing inter-domain resource allocation in a Peripheral Component Interconnect-Express (PCIe) network. One of the plurality of link processors is selected as the management processor. The management processor obtains information about available resources of the PCIe network. When a resource request is received from a requesting processor, the management processor allocates one of the available resources to the requesting processor. the management processor instructs one or more link processors to program one or more inter-domain NTBs according to memory address information of the allocated resource to allow communication between the requesting processor and the allocated resource cross-domain resource access, wherein traffic between the allocated resource and the requesting processor will pass through the one or more inter-domain NTBs.
