Network traffic restoring and playback method

Abstract

The invention discloses a network traffic restoring and playback method. The method is characterized by comprising the steps that (a) traffic capture is implemented, wherein the arrival timestamp corresponding to each data packet is recorded in real time according to the precedence order of arrival of the data packets, and the capture starting time corresponding to each data packet is recorded; (b) restoring and playback are implemented, wherein the corresponding playback starting time is recorded every time the playback is started, and the sending time of the data packets is controlled when the playback is started according to the timestamp of each data packet, the recorded capture starting time, the recorded playback starting time and current time. The network traffic restoring and playback method is easy to implement, the network environments during capture can be restored and reproduced accurately.

Description

technical field [0001] The invention relates to the field of network equipment testing, in particular to a method for restoring and playing back network traffic. Background technique [0002] Testing is a key link to ensure the reliability and stability of network equipment. In the context of high-speed networks, due to the increase in the amount of data, network devices such as switches, firewalls, and network monitoring systems are under increasing traffic pressure. The development of a set of efficient and reliable equipment must undergo more rigorous testing. The continuous improvement of the scale of the Internet requires network security equipment to correctly implement security protection functions in a higher-speed and more complex environment. This makes the development of new security products must have more powerful testing methods and a more realistic testing environment. [0003] Existing testing methods and testing environments can no longer meet these needs ...

[0003] Existing testing methods and testing environments can no longer meet these needs well

The development of testing technology is seriously lagging behind the development speed of the network security industry, which has already had an adverse impact on the development of the network security industry

Since the current enterprise-level test environment still cannot reproduce the complexity of the actual operating network, products that pass the enterprise test process may still be incomplete

Products that have not been fully tested may cause network instability, paralysis or introduce serious security vulnerabilities after deployment into the actual system
