Patent number: 11870698Abstract: This application discloses a congestion control method and related apparatus. In the congestion control method, a network device first obtains statistical information of a target egress queue within a first time period, where the target egress queue is any target egress queue in the network device. The network device determines an explicit congestion notification (ECN) threshold for the target egress queue within a second time period based on the statistical information of the target egress queue within the first time period, where the second time period is chronologically subsequent to the first time period. When a queue depth of the target egress queue exceeds the ECN threshold within the second time period, the network device sets an ECN mark for a data packet in the target egress queue.Type: GrantFiled: December 2, 2021Date of Patent: January 9, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Zhigang Ji, Di Qu, Yinben Xia, Siyu Yan

Patent number: 11695629Abstract: This application relates to the field of communications technologies, and discloses a network parameter (for example, an ECN threshold) configuration method and an apparatus, to dynamically configure a network parameter based on a change of a network transmission characteristic, so that the network parameter is dynamically adapted to a change of network traffic, thereby ensuring network transmission performance. The method includes: obtaining network statistical data corresponding to a first period, where the network statistical data includes a network transmission characteristic of a network device in the first period and a first value corresponding to a specified network parameter; determining, based on the network statistical data, a second value corresponding to the specified network parameter; and configuring the specified network parameter of the network device in a second period to the second value, where the second period is a period after the first period.Type: GrantFiled: March 11, 2022Date of Patent: July 4, 2023Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Siyu Yan, Di Qu, Zhigang Ji, Yinben Xia

Patent number: 11652752Abstract: A network device adds a fixed value to a congestion threshold (CT) when a first period ends. Detects whether a difference obtained by subtracting average traffic load of a queue in the first period from average traffic load of the queue in a second period is greater than a target increase value, sets the CT based on a detection result when the second period ends, where the first period is previous to the second period; marks a received packet when a quantity of packets buffered in the queue is greater than the CT, enqueues the marked packet and sends the marked packet to a receiving device.Type: GrantFiled: December 21, 2021Date of Patent: May 16, 2023Assignee: Huawei Technologies Co., Ltd.Inventors: Zhigang Ji, Di Qu

Patent number: 9020192Abstract: An imaging system captures images of a human submental profile in a dimension controlled environment and utilizes image analysis algorithms for detecting submental changes. Instead of implementing a strict posture control of a subject, the imaging system allows the subject to freely move his/her head in an up-and-down direction and a high speed camera captures this movement through a series of images at varying head-to-shoulder angles. The image analysis algorithms may accurately compare before and after images at similar head-to-shoulder angles to identify changes in a human submental profile using a series of measurements and checkpoints.Type: GrantFiled: March 13, 2013Date of Patent: April 28, 2015Assignee: Access Business Group International LLCInventors: Di Qu, Gopa Majmudar
