A method for restoring and playing back network traffic

Abstract

The invention discloses a method for restoring and replaying network traffic, which is characterized in that: (a) implementing traffic capture: recording the arrival time stamp corresponding to each data packet in real time according to the order in which the data packets arrive, and recording the corresponding time stamp of each data packet; (b) implement restoration playback: record the corresponding playback start time at the beginning of each playback, and replay according to the timestamp of each data packet and the recorded capture start time, playback start time and current time To control the sending time of data packets. The method is simple to implement and can accurately restore and reproduce the network environment at the time of capture.

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
