Abstract
The routing method includes: receiving identification information of nodes to construct a network topology diagram and receiving support rates of connection ports through a controller; monitoring data rates of the connection ports through the controller; receiving a route planning request through the controller; separately calculating costs of links according to the data rates of the connection ports and the support rates of the connection ports after receiving the route planning request through the controller; searching a plurality of candidate paths between a source-destination pair according to the route planning request and the network topology diagram through the controller; summing the costs of links passed by each candidate path to acquire a sum of link-cost of each candidate path through the controller; and, selecting one of the candidate paths with the smallest sum of link-cost as a packet transmitting path between the source-destination pair through the controller.
