Problems solved by technology

[0003] However, when the IPS device performs virus detection, it needs to divert the packets of the entire SDN network to the IPS device for virus detection. When the number of packets in the entire SDN network is large, the IPS device will become the bottleneck of the performance of the entire SDN network. , leading to greater pressure on the IPS device, which in turn affects the overall performance

Embodiment Construction

[0020] In order to make the purpose, technical solution and advantages of the present application clearer, the solution of the present application will be further described in detail below with reference to the accompanying drawings.

[0021] In order to solve the problems in the prior art, the present invention provides a message detection method and device.

[0022] figure 1 It is a schematic diagram of an SDN network scenario applied in the embodiment of the present invention, and the SDN network includes an SDN controller cluster 100 composed of a plurality of SDN controllers (such as SDN controllers 101, 102, 103, and 104), a gateway 105, and a plurality of switches The devices (such as switching devices 106 and 107 ) respectively access multiple hosts (such as hosts 108 and 109 ) and the IPS device 110 of multiple switching devices. The most popular SDN technology is the OpenFlow (Open Flow) protocol. In an SDN network based on the OpenFlow protocol, the switching devic...

Abstract

The invention provides a message detection method and device, wherein the method comprises the following steps of: receiving a mirror image message sent by switching equipment; detecting the mirror image message, and determining a corresponding viral response strategy; and sending a corresponding flow entry to the switching equipment according to the viral response strategy, so that the switching equipment processes the message matched with the flow entry. By means of the message detection method and device disclosed by the invention, the whole performance of an SDN can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a message detection method and device. Background technique [0002] In SDN (Software Defined Network, Software Defined Network) application of IPS (Intrusion Prevention System, Intrusion Prevention System) anti-virus detection function, the IPS device performs virus detection on the packets entering and leaving the entire SDN network, and according to the preset The configured virus response policy blocks or monitors viruses. [0003] However, when the IPS device performs virus detection, it needs to divert the packets of the entire SDN network to the IPS device for virus detection. When the number of packets in the entire SDN network is large, the IPS device will become the bottleneck of the performance of the entire SDN network. , resulting in high pressure on the IPS device, which in turn affects the overall performance. Contents of the invention [0004] Aiming at...
