US Patent 10892992 Load balancing

Example implementations relate to load balancing network traffic flows in a network switching device. According to an example, in a network switching device, a method to load balance network traffic flows across links of the device includes identifying a flow of the network traffic flows as an elephant flow. In response to identifying the flow as an elephant flow, the method collects remote utilization information for the flow. The method recomputes a path for the flow based on local utilization information and the collected remote utilization information and sends the flow along the recomputed path.
