Patent number: 11452127Abstract: This application discloses a network resource scheduling method and an apparatus. A scheduling process includes receiving, by a first network node, a message, where the message includes a network resource that needs to be scheduled between a plurality of network nodes on a multi-hop path. After resource scheduling is performed between the first network node and a second network node, the message is sent to the second network node, to trigger network resource scheduling between the second network node and a third network node. Therefore, end-to-end resource scheduling can be implemented using one message, and end-to-end resource reservation on the multi-hop path can be implemented.Type: GrantFiled: January 29, 2021Date of Patent: September 20, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Bing Liu, Mingui Zhang, Yuefeng Wu, Huanqing Huang
