Design And Implementation Of Http Traffic Replay System

With the rapid development of Internet business,the traditional test methods can not meet the changing test requirements.As a method to automatically generate real traffic and replay test cases.Traffic replay can adapt to the changing test requirements,which is of great significance to the development of the test industry.As a common network transmission protocol for application services,HTTP occupies a large proportion in the test task.This paper studies the existing traffic mirroring technology and application testing tools,studies and analyzes the relevant technical theories,analyzes the functional requirements of the tester for the traffic playback platform from the user's point of view,and designs a new HTTP traffic replay system.The traditional traffic replay system has the problems of business code intrusion and low efficiency.By encapsulating the relevant API of pfring,the system can efficiently capture the online business traffic without affecting the online business,so that the testers have a large number of real test cases.The system developed basic components such as traffic decoder and message playback device,and built a back-end playback system to support regression test,stress test and other test requirements.Due to the premise of not invading the business code,the system does not support the replay of encrypted traffic at present.Based on this work,enterprises can write decoders and replay devices according to their own network transmission protocol requirements,and other infrastructure can be directly applied.
