  • Publication number: 20220200901
    Abstract: A method includes a first node obtaining a first target bandwidth of first traffic on a first path, where the first path is a path used to transmit the first traffic from the first node to a second node. The first target bandwidth is not greater than a minimum value in remaining available bandwidths of single-hop links on the first path, and a single-hop link is a link between two directly connected nodes. The first node sends the first traffic on the first path based on the first target bandwidth. Accordingly, before traffic is transmitted in the network device, available bandwidth resources are predetermined for the traffic, and the traffic corresponding to the available bandwidth resources is transmitted on the determined available bandwidth resources.
