Problems solved by technology

For some devices connected in series to the network, the Bypass method is often used for protection. For key positions, the above redundant backup method can be used, but for non-critical parts, the above-mentioned pure hardware replacement device is used to ensure smooth network, and the cost will be lower. High, and the existing Bypass technology can only detect whether the protected device is alive, and it is difficult to judge whether the protected device has network abnormalities

Embodiment 1

[0020] see figure 1 , a schematic structural diagram of a network data protection device provided in an embodiment of the present invention, including the following components:

[0021] Survival detection module 110: used to regularly send heartbeat detection messages to the protected network device to detect whether the network of the protected network device is smooth, and switch to the preset protection line when the network of the protected network device is not smooth;

[0022] The protected network device may generally be a non-gateway device such as a network data analysis device. Described heartbeat detection message generally can be ICMP bag (Internet Control Message Protocol, i.e. Internet Control Message Protocol, is used to transmit control message between IP machine and router), TCP (Transmission Control Protocol Transmission Control Protocol) bag or UDP ( User Datagram Protocol (User Datagram Protocol) package or some other special data package. Taking the ICMP...

Abstract

The invention discloses a network data protection device and a network data protection method, which are used for protecting data of a network device. The method provided by the invention comprises the following steps: a survival detection module is used for detecting whether the network of the protected network equipment is smooth or not; when the network of the protected network equipment is notsmooth, the protection circuit is switched to a preset protection circuit; a first anomaly detection module is used for periodically sending a data packet with a specific mark and a time stamp to theprotected network equipment, after receiving the returned data packet, if the number of the data packets is inconsistent, the data packet is switched to the protection line; a second anomaly detection module is configured to calculate a delay time of the packet with a specific flag and a timestamp generated by the protected network device, and switch to the protection line when the average delaytime or the longest delay time exceeds a preset threshold value. In the embodiment of the invention, the cost brought by hardware detection can be reduced, and the multi-level network condition detection can accurately confirm the network anomaly problem, which greatly ensures the reliability of the network.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a network data protection device and method. Background technique [0002] With the rapid development of information technology, network access devices are gradually increasing. When a fault occurs, redundant backup of network devices is often required to ensure network data security. For some devices connected in series to the network, the Bypass method is often used for protection. For key positions, the above redundant backup method can be used, but for non-critical parts, the above-mentioned pure hardware replacement device is used to ensure smooth network, and the cost will be lower. High, and the existing Bypass technology can only detect whether the protected device is alive, and it is difficult to judge whether the protected device has network abnormalities. [0003] Therefore, it is necessary to propose a low-cost device or method that can detect network anomalies. ...
