Abstract
A load balancing implementation method, device, and system, where the method includes determining, by a switch according to a meter entry of each output port, a write value corresponding to a real-time flow rate of each output port when a flow entry used to forward traffic does not exist, sending the write value to a controller such that the controller creates a forwarding flow entry used to forward the traffic according to the write value, receiving, by the switch, the forwarding flow entry, and forwarding the traffic through the target output port. Therefore, the controller can obtain a rate range of a real-time flow rate of an output port of the switch and allocate a forwarding path according to the obtained rate range of the real-time flow rate, and implement a better load balancing.
