摘要： This application discloses a load sharing method, an apparatus, 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. In other words, a relatively small link bandwidth may be designed to implement non-blocking switching, to achieve a proper balance between a switching capability and a link bandwidth design.

摘要： A method, device, and system for implementing load balancing are provided, and are applied to a 4-node network structure. Every two nodes in the 4-node network structure are interconnected, and the nodes are, for example, dies. The 4-node network structure includes a source node and a destination node. The method includes: When a bandwidth occupied by ingress traffic flowing into the source node and destined for the destination node is greater than a bandwidth of a fabric side link between the source node and the destination node, the source node selects at least two transmission paths to send the ingress traffic to the destination node; and when the bandwidth occupied by the ingress traffic is less than or equal to the bandwidth of the fabric side link between the source node and the destination node, the source node transmits the ingress traffic on a direct link between the source node and the destination node. This method can save network resources while implementing non-blocking switching of traffic, and meet a low-network delay requirement to some extent.

摘要： This application discloses a communications method and a related device. The network device includes a first node and a second node, and the method includes: the first node obtains 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 the 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. In this way, 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. This ensures that no congestion occurs during traffic transmission on a path, and improves effectiveness and reliability of traffic transmission between nodes in the network device.
