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 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.
