Abstract: A method for implementing load balancing are applied to a 4-node network structure. Every two nodes in the 4-node network structure are interconnected, and the nodes are, e.g., dies. The 4-node network structure includes a source node (SN) and a destination node (DN). According to the method, when a bandwidth occupied by ingress traffic flowing into the SN and destined for the DN is greater than a bandwidth of a fabric side link (FSL) between the SN and the DN, the SN selects at least two transmission paths to send the ingress traffic to the DN; and when the bandwidth occupied by the ingress traffic is less than or equal to the bandwidth of the FSL, the SN transmits the ingress traffic on a direct link between the SN and the DN.

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.
