| The WWW changed greatly in the past years so that HTTP couldn't meet people's demand gradually.In this case,HTTP/2--the second version of HTTP,which is the most important optimization of HTTP,had been published by IETF in 2015.Due to the lack of preliminary validation of how much HTTP/2 can optimize HTTP,only 1.2%of global web sites have already supported HTTP/2.In this case,the sufficient and credible validation of HTTP/2 optimization performance evaluation and research is able to provide more basis for the popularization and the application of the protocol.In this thesis,the comprehensive evaluation and research of the performance of HTTP/2 was provided,then an optimization method of HTTP/2 for specific scenario was proposed.Firstly,a test process was designed based on the scenario of visiting a website through a PC browser.Then the test environment was set up and both simulated and actual experiment were carried up to evaluate and research the optimization performance of HTTP/2.Secondly,due to the limitations of HTTP/2 in mobile applications,a test system was designed and built to evaluate the performance of HTTP/2 in mobile side.Then using the system,both simulated and actual experiment were tested and analyzed.Lastly,considering what HTTP/2 mainly focused on is visiting websites through a PC browser,an optimization of HTTP/2 for mobile applications,which is called HTTP/2-Advance,were proposed to make better use of HTTP/2 for mobile applications.Then both simulated and actual experiment were completed to compare the performance of HTTP,HTTP/2 and HTTP/2-Advance.The results of the experiments above show that HTTP/2 performs better than HTTP in both PC and mobile side,and HTTP/2-Advance,which is proposed in this thesis,makes further improvement for HTTP/2 in mobile scenario.Through this way,the performance and the more efficient utilization method of HTTP/2 were provided to both Web application developers in PC side,and mobile application developers in mobile side. |
