Abstract: A method and device for processing an input/output (I/O) request in a network file system (NFS) includes sending, by a NFS server, a request for parsing the unidentifiable NFS FH to a centralized controller when a NFS file handle (NFS FH) in an I/O request cannot be identified, receiving, by the NFS server, a file identifier that corresponds to the unidentifiable NFS FH from the centralized controller according to the parsing request, where the file identifier is determined according to a pre-stored correspondence between NFS FHs and file identifiers, and processing, by the NFS server, the I/O request according to the file identifier.

Abstract: A network virtualization configuration method, a network system, and a device, where the method includes creating a switch virtual machine (VM), where the switch VM is configured to run a virtual switch, responding to a Peripheral Component Interconnect (PCI) scanning of the switch VM, configuring, using a physical function (PF) driver, a PCI Express (PCIE) device to allocate a corresponding network resource to the switch VM, and initializing the PCIE device using the PF driver, where a default forwarding rule of the initialized PCIE device includes setting a default forwarding port of the PCIE device to a VF receiving queue (VF 0) corresponding to the switch VM. Hence, a cross-platform virtual switch solution can be implemented, thereby improving flexibility of deploying a virtual switch, and implementing compatibility with different hypervisors/VM monitors (VMMs).

Abstract: Embodiments of the present invention disclose a method, an apparatus and a system for joint optimization. The method for joint optimization includes: decomposing the joint optimization of an entire network into the joint optimization performed in each sub-network, regarding a bandwidth requirement for a server off the sub-network as a bandwidth requirement for a virtual server on a port, iteratively performing the joint optimization in each sub-network, and applying results of the joint optimization in the network. In the embodiments of the present invention, the bandwidth requirement for the server off the sub-network is regarded as the bandwidth requirement for the virtual server on the port, the joint optimization is iteratively performed in each sub-network, and the results of the joint optimization are applied in the network, so that the joint optimization of the entire network is performed in parallel.
