Problems solved by technology

[0003] In the process of realizing the embodiment of the present invention, the inventor finds that: in the prior art, the MonSmap method only realizes the Qos monitoring of SDN. For SDN network monitoring, its monitoring content is not comprehensive enough; distributed collaborative monitoring (DCM) although It can realize data flow-level operation monitoring, but because it is not based on OpenFlow, its versatility is relatively limited

[0070] On the basis of the first embodiment of the present invention, it also includes:

[0071] The aggregation-level information is stored in a data storage unit; wherein, the data storage unit is any one of a relational database, a key-value database, or an unstructured file system.

[0072] In the embodiment of the present invention, the NPB device stores the aggregation-level information in a data storage unit, so that the controller can obtain corresponding monitoring data from the data storage unit later, and the data storage unit can Be it a relational database, a key-value database, or an unstructured file system.

no. 3 example

[0074] On the basis of the second embodiment of the present invention, it also includes:

[0075] Return a monitoring identifier to the controller according to the aggregation level information; wherein, the monitoring identifier is used to enable the controller to locate from the data storage unit corresponding to the flow state request message through the monitoring identifier monitoring traffic data.

[0076] In the embodiment of the present invention, the NPB device stores the flow monitoring data required by the flow state request message into the data storage unit, and returns a monitoring identifier to the controller as a response to the flow state request message ID, so that the upper layer network can locate the monitoring flow data corresponding to the flow state request message from the data storage unit through the monitoring identification ID.

no. 4 example

[0078] On the basis of the third embodiment of the present invention, after the aggregation of the data statistics information to obtain the aggregation-level information required for traffic monitoring, further includes:

[0079] Analyzing and monitoring the change speed of the data flow according to the aggregation-level information.

[0080] The monitoring sampling time slot and the corresponding polling time slot of the switch set are adjusted according to the change speed of the monitoring data flow.

[0081]In the embodiment of the present invention, the NPB device analyzes and monitors the change rate of the data flow according to the aggregation level information, and then adjusts the monitoring sampling time slot and the polling time slot of the corresponding switch set according to the change speed of the monitoring data flow, When the data change of the monitoring data flow is not significant, the monitoring sampling time slot can be increased by a preset multiple o...

Abstract

The invention discloses a self-adaptive monitoring method, device, NPB device and computer-readable storage medium of network flow. The method comprises the following steps: receiving a flow state request message sent by a controller at each preset monitoring sampling time point, And analyze the flow state request message to generate a scheduling instruction; select a set of switches that need to be monitored for traffic from the switching selection library according to the scheduling instruction; wherein, the switching selection library is used to store the polling time stamp The set of switches that need to be polled; according to the scheduling instruction, poll all the switches in the corresponding switch set within the polling time stamp to collect data statistics; aggregate the data statistics to obtain the traffic monitoring required The aggregation level information improves the accuracy and real-time performance of network traffic monitoring while reducing monitoring overhead.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an adaptive monitoring method and device for network traffic, NPB equipment and a computer-readable storage medium. Background technique [0002] SDN, or Network Definition Software, is a powerful candidate for the next-generation Internet architecture that has emerged in recent years. Its core idea is to separate the data plane from the forwarding plane, making the network programmable, which greatly reduces the complexity of network management. . At the same time, traffic monitoring is a very important part of network management. Many network management applications are based on accurate and timely network status statistics, such as load balancing technology, traffic engineering, intrusion detection, etc., which are widely used in data centers. The existing network traffic monitoring methods include: the first one: MonSmap, which is an SDN monitoring algorithm b...
