Abstract: An accelerator loading apparatus obtains an acceleration requirement, where the acceleration requirement includes an acceleration function and acceleration performance of a to-be-created virtual machine, determines an image that meets the acceleration function and the acceleration performance, and determines a target host in which an available accelerator that can load the image is located, and then sends an image loading command to the target host. The image loading command includes a descriptor of the image, and is used to enable the target host to load the image for the available accelerator. In the method, a target host that can create the virtual machine may be determined based on the acceleration function and the acceleration performance of the to-be-created virtual machine, and an image used for acceleration is loaded to an available accelerator of the target host, to implement dynamic accelerator loading and deployment.

Abstract: An accelerator loading apparatus obtains an acceleration requirement, where the acceleration requirement includes an acceleration function of a to-be-created virtual machine and acceleration performance of the to-be-created virtual machine. The accelerator loading apparatus determines a target accelerator that meets the acceleration function of the to-be-created virtual machine and the acceleration performance of the to-be-created virtual machine. The accelerator loading apparatus determines an image corresponding to the target accelerator, and sends an image loading command to a target host in which the target accelerator is located, where the image loading command is used to enable the target host to load the image for the target accelerator based on the image loading command.

Abstract: A method for implementing fault detection includes: instructing, by a detection device, a detected device to configure a detected path and a return path, where the detected path is a path from a first physical port of the detected device to a second physical port of the detected device via a target unit of the detected device, the return path is a path from the second physical port to the detection device, and the target unit is a VNF or an accelerator; sending a detection packet to the detected device through the first physical port; and when receiving the detection packet transmitted through the detected path and the return path, determining that the detected path is not faulty. According to the method, it can be further determined that the path that passes through the VNF or the accelerator is not faulty.

Abstract: The disclosure relates to a method, device and system for processing content. In the method: a server receives a content acquiring request transmitted by a terminal. The server determines a first storage node list according to a mapping relation acquired in advance between contents and storage nodes. The first storage node list includes a plurality of first storage nodes that store a first content corresponding to the content acquiring request. The server transmits a sorting request to a network storage management server and receives a sorting result transmitted by the network storage management server. The sorting result includes priorities of the plurality of first storage nodes. The server transmits a content acquiring response to the terminal, where the content acquiring response includes first access information and priority of at least one of the first storage nodes.

Abstract: A driver loading method and a server, where when receiving a service request, the server determines a first global index and a first global virtual function (VF) identifier corresponding to a first function description of a designated function included in the service request, determines a virtual machine (VM) corresponding to the service request, associates the first global VF identifier with the VM, allocates a first local index on the VM to the designated function, creates a correspondence between the first local index and the first function description, and sends the correspondence to the VM. The VM loads, according to the correspondence, a driver of the designated function for a first VF corresponding to the first global VF identifier. According to the foregoing method, different drivers can be loaded for VFs that have different functions and that are virtualized by a Peripheral Component Interconnect Express (PCIe) device.
