Patent number: 11777857Abstract: This application relates to the field of communications technologies, and discloses a service forwarding method and a network device that performs such method. The method includes: forwarding, by a first network device, a data packet of a first service to a second network device in a period (T1); and if the data volume of the forwarded first service reaches a threshold, forwarding, by the first network device, a data packet of a second service to the second network device. The first service is a low-latency service, and the second service is a non-low-latency service. In addition, the period (T1) is determined based on a delay allowed by a device for forwarding the data packet of the first service, and the threshold is a value determined based on a maximum transmission rate of the first service.Type: GrantFiled: September 15, 2021Date of Patent: October 3, 2023Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Yuanlong Jiang, Hengjun Zhu, Hongguang Guan
