Abstract:
A network data transmission method is provided. A switch device receives one or more data flows, classifies each of the received data flows into one of two classes according to data features of the data flow by using a decision tree model established by a flow table pipeline of the switch device. If a data flow belongs to a first class, the switch device reports the data flow to a controller, so that the controller computes a transmission path for the data flow. If a data flow belongs to a second class, the switch device obtains a transmission path for the data flow according to local flow table information, and transmits the data flow according to the obtained transmission path. Data flows are classified and filtered by using a switch, so as to improve network transmission efficiency while ensuring bearing capability of a network control system.

Claim (Index 4):
The method according to  claim 3 , wherein classifying the data flow into one of two classes using the decision tree model comprises:\n inputting the data features of the data flow to the decision tree model; and at each decision node that receives the data features of the data flow, matching a data feature corresponding to the decision node with a binary wildcard that is converted from a match field of a flow table corresponding to the decision node, and determining, according to a matching result between the data feature and the binary wildcard, a splitting direction to a next node connected to decision node; wherein the connection between nodes of the decision tree model is indicated by a \u201cGo to Table n\u201d instruction in an instruction field of the flow table, and wherein the classification of the data flow is performed node by node until the data features reach a leaf node.
