Abstract

A network device management method and apparatus are provided. The method includes: generating statistical traffic data, where the statistical traffic data includes at least one of data traffic of a port of a network device, a queue status of the network device, traffic of a data packet that passes through the network device, or traffic of a target data flow that passes through the network device; and sending the statistical traffic data to a controller. The controller receives statistical traffic data sent by multiple network devices, and can adjust a path of a data flow dynamically according to a traffic status of each port of the multiple network devices or a traffic status of a transmitted data flow in the multiple network devices and by changing routing tables of the network devices, thereby improving link utilization, and further improving network performance.

First claim

What is claimed is:

1. A network device management method, comprising:
receiving, from a controller, an individual instruction message to instruct a network device to return statistical traffic data, wherein the individual instruction message comprises statistical period information;
generating the statistical traffic data periodically according to the statistical period information contained in the individual instruction message, wherein the statistical traffic data comprises one or more of a quantity of data of a port of the network device, a queue status of the network device, a quantity of data packets that pass through the network device, and a quantity of target data flows that pass through the network device, wherein the queue status comprises a queue occupancy rate, and the target data flows are data flow to be measured; and
sending the statistical traffic data to the controller periodically according to the statistical period information contained in the individual instruction message.

2. The method according to claim 1 , wherein the individual instruction message comprises an identifier of a target data flow, and the statistical traffic data comprises the quantity of the target data flows; and
wherein the generating the statistical traffic data according to the individual instruction message comprises:
determining the target data flow according to the identifier of the target data flow; and
collecting statistics of the quantity of the target data flows, so as to generate the statistical traffic data.

3. The method according to claim 1 , wherein the individual instruction message comprises an identifier of a target data flow, and the statistical traffic data comprises the quantity of the target data flows; and
wherein the generating the statistical traffic data according to the individual instruction message comprises:
determining the target data flow according to the identifier of the target data flow; and
collecting statistics of the quantity of the target data flows, so as to generate the statistical traffic data.

4. An apparatus, comprising:
a transceiver; and
a processor coupled with the transceiver,
wherein the transceiver is configured to receive, from a controller, an individual instruction message to instruct the apparatus to return statistical traffic data, wherein the individual instruction message comprises statistical period information;
wherein the processor is configured to generate the statistical traffic data periodically according to the statistical period information contained in the individual instruction message, wherein the statistical traffic data comprises one or more of a quantity of data of a port of the apparatus, a queue status of the apparatus, a quantity of data packets that pass through the apparatus, and a quantity of target data flows that pass through the apparatus, wherein the queue status comprises a queue occupancy rate, and the target data flows are data flows to be measured, and
wherein the transceiver is configured to send the statistical traffic data to the controller periodically according to the statistical period information contained in the individual instruction message.

5. The apparatus according to claim 4 , wherein the individual instruction message comprises an identifier of a target data flow, and the statistical traffic data comprises the quantity of the target data flows; and
wherein the processor is further configured to:
determine the target data flow according to the identifier of the target data flow; and
collect statistics of the quantity of the target data flows, so as to generate the statistical traffic data.

6. The apparatus according to claim 4 , wherein the individual instruction message comprises an identifier of a target data flow, and the statistical traffic data comprises the quantity of the target data flows; and
wherein the processor is further configured to:
determine the target data flow according to the identifier of the target data flow; and
collect statistics of the quantity of the target data flows, so as to generate the statistical traffic data.

7. An apparatus, comprising:
a transceiver; and
a processor coupled with the transceiver,
wherein the transceiver is configured to:
send an individual instruction message to each of one or more network devices to instruct each of the one or more network devices to return statistical traffic data, wherein the individual instruction message comprises statistical period information for each of the one or more network devices;
receive the statistical traffic data that is sent periodically by each of the one or more network devices according to the statistical period information contained in the individual instruction message, wherein the statistical traffic data comprises one or more of a quantity of data of a port of each network device, a queue status of each network device, a quantity of data packets that pass through each network device, and a quantity of target data flows that pass through each network device, wherein the queue status comprises a queue occupancy rate, and the target data flows are data flows to be measured, and
wherein the processor is configured to manage the one or more network devices according to the statistical traffic data that is periodically received from the one or more network devices.

8. The apparatus according to claim 7 , wherein the individual instruction message comprises an identifier of a target data flow, and the statistical traffic data comprises the quantity of the target data flows.

9. The apparatus according to claim 7 , wherein the individual instruction message comprises an identifier of a target data flow, and the statistical traffic data comprises the quantity of the target data flows.
