Abstract: A method is applied to a ring link, where the ring link includes a first node, a second node, a third node, and a fourth node in sequence. According to the method, the first node receives first traffic, where the first node is a source node that sends the first traffic on the ring link; and the first node sends the first traffic to the third node, where two reachable paths with equal hop counts are included from the first node to the third node, the first node sends the first traffic to the third node on a preset first transmission path, the first transmission path passes through the second node, and the first transmission path is one of the two reachable paths with equal hop counts. This method can reduce computing load of nodes while implementing non-blocking switching of traffic between the nodes.

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.

Abstract: According to a load sharing method and a network device, traffic distribution ratios are correspondingly preset for different paths. For example, an equivalent resistance method is used as a load sharing algorithm provided in embodiments of this application, to calculate a corresponding traffic distribution ratio for each possible path. The traffic distribution ratio and the corresponding path are preset for a corresponding node. In this way, traffic entering a network device is distributed to each path in the network device based on the preset ratio, without causing excessive bandwidth pressure on a shortest path, to implement relatively optimal load balancing. For the network device with either a ring network structure or a stereoscopic network structure, a requirement for a link bandwidth between the nodes in the network device can be reduced.

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.
