Patent number: 11706113Abstract: This application provides an example delay measurement method and an example network device. The method includes receiving, by a first network device, a first service flow. The method also includes determining, by the first network device, a first delay value based on a first measurement code block in the first service flow. The first delay value is a time difference between a first moment at which the first measurement code block is detected in the first network device and a second moment at which the first measurement code block is detected in the first network device.Type: GrantFiled: January 27, 2021Date of Patent: July 18, 2023Assignee: Huawei Technologies Co., Ltd.Inventors: Renlei Wang, Zhe Lou, Min Zha, Zhigang Zhu

Patent number: 11563521Abstract: A method of data processing is applied to a communications device including a first sublayer. A physical sublayer is added above a physical coding sublayer (PCS) of a physical layer, and the physical sublayer is connected to media independent interfaces (xMIIs) with different Ethernet rates. Data signals from different media access control clients (MAC) are interleaved using the physical sublayer. Then, a tx_cmd command is used to instruct the PCS to correspondingly encode an xMII signal. Finally, an encoded xMII signal is sent through a port. According to this method, an encoding function of the PCS may continue to be used, to decouple interleaving from encoding and perform the interleaving through an xMII interface. In this case, port channelization can be implemented for ports with multiple rates, and transmission of a high-priority service is ensured when there is an excessively large quantity of service flows in a transmission process.Type: GrantFiled: February 1, 2021Date of Patent: January 24, 2023Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Li Xu, Min Zha, Renlei Wang, Zhigang Zhu

Patent number: 11411848Abstract: Embodiments of the present invention provide a flexible Ethernet latency measurement method and a related device. The method includes: determining, by a first node, first duration based on a first downlink transmission time interval and a second downlink receiving time interval; determining, by the first node, second duration based on a first uplink transmission time interval and a second uplink receiving time interval; and calculating, by the first node, an uplink and downlink latency difference between the first node and the second node based on the first duration and the second duration. According to the embodiments of the present invention, costs for measuring an asymmetric uplink and downlink latency can be reduced.Type: GrantFiled: June 23, 2020Date of Patent: August 9, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Renlei Wang, Xiaojun Zhang

Patent number: 11196675Abstract: The present disclosure relates to flexible-Ethernet data processing methods and devices. One example method includes acquiring a to-be-switched first client service flow, where the first client service flow is a service flow suitable for transmission on a flexible Ethernet, performing first rate adaptation from a source clock domain to a target clock domain on the first client service flow to obtain a second client service flow that matches the target clock domain, and performing serial-to-parallel conversion on the second client service flow in the target clock domain to obtain a parallel client slot flow.Type: GrantFiled: April 29, 2020Date of Patent: December 7, 2021Assignee: Huawei Technologies Co., Ltd.Inventors: Xingyao Chen, Xiaojun Zhang, Shuai Xiao, Renlei Wang

Publication number: 20200288468Abstract: This application provides a data transmission method and a device. The method includes: adding data of at least one first device to a slot in a slot group, where the slot group includes N slots, a first slot is any slot in the slot group, the first slot includes M subslots, sequence information of the M subslots is located in any one of the M subslots, and both M and N are positive integers; and sending the data of the at least one first device to a second device by using the slot group. Sequence information of subslots of a slot is placed in any subslot of the slot, instead of being placed in an overhead frame, and therefore a receive end can learn of information about a sequence relationship in a relatively short time, reducing a time interval.Type: ApplicationFiled: May 20, 2020Publication date: September 10, 2020Inventors: Shuai XIAO, Min ZHA, Xingyao CHEN, Renlei WANG
