Abstract: A device for controlling network routing configurations is configured to obtain a predicted traffic matrix and a plurality of traffic matrices, and to determine, from a plurality of clusters, arranged in a hierarchical structure over the predicted traffic matrix and the plurality of traffic matrices, a first cluster allocated to a lower hierarchy level that contains the predicted traffic matrix. Each of the clusters is associated with a routing configuration, and the plurality of clusters are allocated to at least two different hierarchy levels. The device selects, from the plurality of clusters, a second cluster allocated to a higher hierarchy level that includes at least the first cluster and a third cluster allocated to the lower hierarchy level that contains a current traffic matrix, determine a second routing configuration associated with the second cluster; and activate the second routing configuration as a network routing configuration.

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: This application describes a network device, a controller, a queue management method, and a traffic management chip. The method may be applied to a traffic management chip that uses an HQoS technology, and can include receiving a queue management instruction sent by a controller, where the queue management instruction includes an identifier of a first scheduler and an identifier of a first queue, and the first scheduler is one of multiple first-level schedulers. The method may also include controlling, according to the queue management instruction, scheduling of the first queue by the first scheduler, where a queue scheduled by the first scheduler belongs to a queue resource pool of the TM chip, and the queue resource pool includes at least one to-be-allocated queue. In this application, decoupling between queue allocation and the first-level schedulers is implemented, flexibility of queue allocation is improved, and utilization of queue resources is improved.

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.
