Publication number: 20220368633Abstract: This application describes a congestion control method and apparatus. In this application, a network device obtains time information of one or more congestion packets in a sent first data stream, where the one or more congestion packet carries a flag indicating a congestion notification. When the first data stream is congested, the network device obtains a first congestion notification packet based on the time information of the one or more congestion packets in the first data stream, where the first congestion notification packet notifies that a packet is congested beyond a first specified interval. The network device then sends the first congestion notification packet. According to the solutions in this application, a rate of a data stream can be prevented from being increased when the data stream is congested, and packet transmission efficiency is improved.Type: ApplicationFiled: July 21, 2022Publication date: November 17, 2022Inventors: Heyang LIU, Hewen Zheng, Lei Han, Jinfeng Yan, Binghui Wu, Huafeng Wen, Peiying TAO

Publication number: 20220188358Abstract: Described herein are techniques for processing content items for presentation via a content feed of an online service. Upon receiving a request associated with a particular end-user of an online service for a content feed, a connection graph is analyzed to identify a plurality of content items that are eligible for presentation to the end-user. Some subset of content items that share a common relationship with the end-user, as indicated by a common edge in the connection graph, are identified. This subset of content items is then grouped together for presentation within the content feed in a content carousel, where the content carousel is positioned within the content feed, relative to other content items, based on the highest ranking content item presented via the content carousel.Type: ApplicationFiled: December 10, 2020Publication date: June 16, 2022Inventors: James Hung, Samson Hin-Leung CHOI, Fangbing QIU, Collin Dang YEN, Heyang LIU, Xiang LIN, Garrett Gabriel WELSON, Kangning HU, Ying XUAN, Yanbin JIANG, Diya Dutt SHARMA, Manas Haribhai SOMAIYA
