Embodiment 1

[0035] Referring to Fig. 4, the present invention provides a method for simulating network damage, which specifically includes the following steps:

[0036] Step 101: first generate a configuration table for recording abnormal simulation information, and save it in the configuration table memory.

[0037] Users can generate configuration tables through software, or through statistical data from other instruments, or mathematical formulas (such as normal distribution, background noise, etc.). The configuration table provides the configuration data of the simulated packet switching network. There is a certain configuration item (ie record) for each normal data packet in the table. This configuration item records the abnormal simulation information, which determines the content of the corresponding data packet. Changes, delay changes, retransmission characteristics and discarding conditions, etc., control the sending time and sending content of each data packet, so as to achieve ...

Embodiment 2

[0061] Referring to Figure 6 and Figure 7, the present invention also provides a device for simulating network damage, including:

[0062] 1) a configuration module, configured to generate a configuration table for recording abnormal simulation information;

[0063] 2) an abnormal addition module, used to generate abnormal data packets according to the abnormal simulation information in the configuration table when receiving normal data packets, and calculate the sending time of abnormal data packets;

[0064] 3) A sending module, configured to send the abnormal data packet according to the sending time calculated by the abnormal adding module.

[0065] In the configuration table, corresponding to each normal data packet, there is a record of relevant abnormal simulation information. The abnormal simulation information usually includes the abnormal type and delay time, etc.; the abnormal adding module generates abnormal data packets according to the abnormal type and delay tim...

Abstract

To overcome defects in prior art, the provided simulation method for network damage comprises: generating configuration table contained abnormal simulation information; generating abnormal data package according to abnormal simulation information to calculate the sending time and thereby send abnormal data package. This invention is simple and convenient, reduces cost and testing period greatly, and can construct abnormal simulation with high precision for wide quantitative testing.

Description

technical field [0001] The invention relates to the field of network testing, in particular to a method and device for simulating network damage. Background technique [0002] So far, Ethernet is still the most active technology in the field of computer interconnection. Ethernet technology based on packet transmission network has been rapidly popularized by virtue of its price advantage and versatility, and is gradually expanding its service field. . With the continuous development of the Internet, the bandwidth between some traditional network devices (such as routers) can no longer meet the requirements. Higher and more efficient interconnection technologies are needed to connect these network devices to form the backbone of the Internet. 1000M Ethernet has become the backbone of the Internet. preferred technology. It has become more and more popular for users to access the MAN through Ethernet technology to realize services such as Internet access, file download, video ...
