Patent number: 11882022Abstract: A packet sending method and device. The first node sets a next-hop of the routing information to a next-hop through which the first node reaches the first route source. The destination address of the routing information is the address prefix. When the second route source is superior to the first route source, the first node switches the next-hop of the routing information to a next-hop through which the first node reaches the second route source. Then, the first node adds, to a target packet, path information of a forwarding path from the first node to the second route source according to the switching operation, where a destination address of the target packet matches the address prefix. Finally, the first node forwards the target packet to the second route source through the forwarding path.Type: GrantFiled: September 2, 2022Date of Patent: January 23, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Guoquan Liu, Ruqin Lan, Zuliang Wang, Zhibo Hu, Chenxi Li

Publication number: 20150195169Abstract: A method, device, and system for measuring network packet loss. A sender performs data packet counting processing on a service stream sent to a receiver to obtain a first data packet count corresponding to a measurement period identifier. The sender sends an OAM packet including a measurement period identifier to be queried to the receiver. The OAM packet and a data packet of the service stream are transmitted on a same path. The sender receives a second data packet count that is returned by the receiver after the receiver receives the OAM packet. The second data packet count is a count obtained by the receiver by performing data packet counting processing on the received service stream. The sender determines a network packet loss situation according to the first data packet count and the second data packet count.Type: ApplicationFiled: March 24, 2015Publication date: July 9, 2015Inventors: Yanjun Liu, Zuliang Wang, Hongming Liu
