Publication number: 20240422106Abstract: A computerized method for processing packets in parallel using a reorder queue is described. As packets are received, it is determined which packet is the first packet in the flow. Once identified, the first packet in the flow, along with all other packets in the flow, is sent to the reorder queue while only a copy of the first packet in the flow is sent to a packet scheduler for processing on one of a plurality of processing cores. After the copy of the first packet in the flow is processed, the reorder queue releases each of the packets for the flow from the reorder queue in an order in which they were received. Thereafter, each of the packets released from the reorder queue are processed based on the processing of the copy of the first packet.Type: ApplicationFiled: June 19, 2023Publication date: December 19, 2024Inventors: Tian TAN, Anshuman VERMA, Tushar GARG, Taylor Catherine SWANSON

Patent number: 11936453Abstract: Multi-User Multiple Input, Multiple Output (MU-MIMO) data transmissions are provided with a forward-predictive precoding matrix to mitigate the effects of a change in a state of a communication channel. First and second soundings are performed, at first and second times, to a receive antenna over a channel and, responsive to each of the soundings, first and second Channel State Information (CSI) are received. Based on the first and second CSI, a change in a state of the channel over a time period between the first and second time is determined. Based on the change in the state of the channel, a forward-predictive channel state matrix and/or a forward-predictive precoding matrix are determined that reflect a state of the channel at a future time and that are consistent with the determined change in the state over the time period.

Patent number: 11709912Abstract: A method of detecting abnormality may include the following steps. A normal-value range of a parameter for a target object is determined based on historical values of the parameter in a preset time period or at a preset time point. Whether the target object is abnormal is determined based on the normal-value range and the value of the parameter for the target object in the preset time period or at the preset time point within a current time cycle. Further, another normal-value range may be determined based on historical deviation values for the target object in historical time periods or at historical time points before the preset time period or the preset time point. Whether the target object is abnormal is determined based on either of the two normal-value ranges.Type: GrantFiled: December 28, 2020Date of Patent: July 25, 2023Assignee: Hangzhou DPtech Technologies Co., Ltd.Inventors: Tian Tan, Zhongliang Chen, Xiaolong Li
