  • Publication number: 20250007853
    Abstract: The present disclosure relates to queue scheduling methods and apparatuses. In one example queue scheduling method, a queue scheduling apparatus determines first bandwidth, where the first bandwidth indicates a rate at which a packet on an outbound interface is dequeued. The queue scheduling apparatus determines a first scheduling parameter based on the first bandwidth and a first scheduling frequency, where the first scheduling frequency indicates a maximum quantity of scheduling times per unit of time, and the first scheduling parameter indicates a length of a packet scheduled each time. The queue scheduling apparatus schedules, based on the first scheduling parameter, to dequeue the packet on the outbound interface.

  • Patent number: 11658924
    Abstract: This application provides a buffer allocation method and a device. The method includes determining, by a device, a first output rate of a first queue on the device and a second output rate of a second queue on the device. The method also includes separately allocating, by the device, a first buffer to the first queue and a second buffer to the second queue based on a ratio of the first output rate to the second output rate. The device separately allocates a buffer to each of queues based on a ratio of output rates of the queues, so that a ratio of output traffic of the queues meets an expected scheduling ratio.

  • Publication number: 20230103529
    Abstract: A method and device for identifying an attribute word of an article are provided. The method includes: acquiring an article information of a to-be-identified article; performing word segmentation on the article information; identifying a word segmentation result based on a preset rule; determining a similarity of a first attribute word to each standard attribute word to determine whether the first attribute word is valid when the first attribute word is acquired; identifying the word segmentation result based on a sequence labeling model to acquire a second attribute word-when the first attribute word is invalid or when the first attribute word is not acquired; determining a similarity of each of the second attribute words to each standard attribute word; and determining a final attribute word of the to-be-identified article based on the similarity of each of the second attribute words.

  • Publication number: 20230035875
    Abstract: Provided are a method and device for preparing adiponitrile. The method of the present disclosure comprises the steps of a first hydrocyanation reaction, an isomerization reaction and a second hydrocyanation reaction, wherein online Raman spectroscopy is used for detecting the content of a specific component in the system; and the reaction conditions are regulated based on the detection results, so as to achieve precise control of the materials in each step of the reaction system. The method of the present disclosure can reduce an amount of butadiene, thereby reducing the subsequent energy consumption needed for recycling butadiene and equipment investment after reaction; by monitoring the content of hydrocyanic acid in real time, the residue of hydrocyanic acid is reduced to a lower level, and the operation safety and the stability of a catalyst during reaction are improved; and the loss of the catalyst is reduced.
