Embodiment Construction

[0027] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0028] like figure 1 As shown, the present invention is based on the traffic monitoring algorithm of the SDN architecture, and the method has the following steps: S101: the user configures the traffic monitoring strategy on the SDN controller; S102: the SDN controller receives the message from the SDN switch, and analyzes the destination IP and the source IP ; S103: The SDN controller receives the private extended Experimenter message from the SDN switch, and parses the Experimenter message; S104: The SDN switch detects the traffic rate, and reports the detection result to the SDN controller. The traffic monitoring process based on the SDN architecture of the present invention is uniformly calculated and managed by the SDN controll...

Abstract

The invention relates to a flow control algorithm based on SDN architecture. The method includes the steps that S101, a user configures a flow control strategy on an SDN controller; S102, the SDN controller receives a message from an SDN switch, and a target IP and a source IP are analyzed; S103, the SDN controller receives a private extension Experimenter message from the SDN switch, and the Experimenter message is analyzed; S104, the SDN switch detects the rate of flow, and the rate is reported to the SDN controller according to the detection result. Compared with the prior art, the flow control process based on the SDN architecture is calculated by the controller in a unified mode and managed in a centralized mode, all flow control configuration is centralized in the controller, and management and later operation are convenient.

Description

technical field [0001] The present invention belongs to the field of network communication technology, in particular to the technical field of network communication flow monitoring, and specifically relates to a flow monitoring algorithm based on SDN architecture. Background technique [0002] Network security has always been a hot issue in the network field, and the network is full of network attacks all the time. Traffic policing can effectively prevent the impact of a large amount of data in the network on the network, and ensure the efficient and stable operation of the user network. [0003] In traditional networks, network traffic is often monitored, but expensive monitoring equipment is often used, which has a single function and does not have high scalability, making it difficult to adapt to flexible and changeable network attacks. In addition to the corresponding safety knowledge reserve, they also need to master the use methods of various equipment, and changing d...
