Problems solved by technology

However, the deployment of detection equipment in the network will cause a problem: the detection equipment connected in series to the link will increase the vulnerability of the link. When the detection equipment fails, it will cause the interruption of the normal link, resulting in the data on the link The problem that traffic cannot be transmitted
[0005] In the process of realizing the above traffic switching, the inventor found at least the following problems in the prior art: after shielding the circuit detection equipment, if the circuit protection equipment fails , the data traffic is blocked on the circuit detection device and cannot be sent to the receiving device

Embodiment 1

[0037] The embodiment of the present invention provides a flow monitoring and switching method, such as figure 2 As shown, the method includes the following steps:

[0038] 201. Receive data traffic sent by the sending device through the OPM.

[0039] After the data traffic sent by the sending device flows through the OPM, the OPM sends it to the EPM.

[0040] 202. Monitor the average flow value on the flow output port on the EPM.

[0041] The EPM has a flow input port and a flow output port, the flow input port receives the data flow sent by the OPM, and the average flow value is monitored on the flow output port.

[0042] The unit of the average flow value is packet per second (Packet Per Second, PPS), which is used to indicate the average number of output data packets per second on the flow output port within a period of time (for example, 60 seconds).

[0043] 203. Compare the average flow value with the flow threshold.

[0044] 204. When the average flow value is sma...

Embodiment 2

[0048] The embodiment of the present invention provides a flow monitoring and switching method, such as image 3 As shown, the method includes the following steps:

[0049] 301. Set a traffic threshold and a comparison time interval.

[0050]The flow threshold can be set at 50PPS to 200PPS. When the average flow value on the flow output port on the EPM is less than the flow threshold, it indicates that the EPM has failed and blocked the data flow, and data flow needs to be switched. When the average flow value on the flow output port on the EPM is greater than or When it is equal to the traffic threshold, it indicates that the EPM is not blocked, and there is no need to switch the data traffic.

[0051] It should be noted that the flow threshold is a numerical interval. When judging whether the EPM fails, the comparison standard is whether the average flow value is less than the lower limit of the flow threshold. In this embodiment, the lower limit is 50PPS. Only the When t...

Embodiment 3

[0071] The embodiment of the present invention provides a flow monitoring and switching device, such as Figure 7 As shown, the device includes: a receiving unit 71, a monitoring unit 72, a comparison unit 73 and a switching unit 74, wherein,

[0072] The receiving unit 71 is configured to receive data traffic sent by the sending device through the OPM.

[0073] The monitoring unit 72 is configured to monitor the average flow value on the flow output port of the EPM.

[0074] The unit of the average flow value is PPS, which is used to indicate the average number of output data packets per second on the flow output port within a period of time (for example, 60 seconds).

[0075] The comparing unit 73 is configured to compare the monitored average flow value with the flow threshold.

[0076] When the average flow value is less than the flow threshold, the data flow is switched to OPM. When the average flow value is less than the flow threshold, it indicates that the circuit p...

Abstract

The invention discloses a method, a device and a system for traffic monitoring and switching, relates to the network security field, and aims to monitor malfunction of circuit protective equipment and switch traffic when the circuit protective equipment malfunctions. The method includes receiving data traffic sent by a sending device through a light path protective device; monitoring an average traffic value at the traffic output end of the circuit protective equipment; comparing the average traffic value with a threshold value; switching the data traffic to the light path protective device, and send the data traffic directly to a receiving device through the light path protective device when the average traffic value is smaller than the threshold value. The method, the device and the system for the traffic monitoring and switching is mainly applied to the network security field.

Description

technical field [0001] The invention relates to the field of network security, in particular to a flow monitoring and switching method, device and system. Background technique [0002] With the wide application of network technology in modern life, more problems have been exposed in Internet security: the indiscriminate dissemination of illegal information on the Internet, the proliferation of spam, virus and Trojan horse hacking, and the increase in financial crimes, etc. User personal information security and national information security All are under great threat, and the elimination of potential safety hazards is imminent. [0003] In order to effectively eliminate hidden dangers in the network and realize user needs such as green Internet access, virus detection, and attack prevention, detection devices are deployed at all levels of the network to handle security services. Taking a firewall as an example, the detection device of the firewall is deployed on a link on t...
