【摘要】：對移動互聯網的應用進行溯源是網絡安全監(jiān)管的需要；對用戶上網內容進行審計和用戶行為進行分析,分析用戶的喜好習慣和行為特征,從而讓運營商為用戶提供差異化的服務。因此移動互聯網應用審計平臺項目,具有重大的社會效益和經濟效益,不但可以提高網絡安全的管理水平,及時發(fā)現網絡中的薄弱環(huán)節(jié)及可疑因素、找出安全問題,還可以促進移動互聯網發(fā)展。但隨著網絡帶寬的不斷增加,對移動審計系統的性能要求也越來越高,目前采用通用技術實現方案的審計平臺的處理數據效率還不能滿足大數據處理數據的要求,因此對移動互聯網應用審計平臺的性能優(yōu)化成為本文的研究內容。本文對移動互聯網應用審計平臺進行介紹,包括網絡的整個拓撲結構、傳統審計平臺的拓撲結構。然后對移動互聯網應用審計平臺的性能進行分析并提出解決方案,用緩存技術來解決數據庫性能優(yōu)化的問題。在對Memcached應用到的技術詳細描述的基礎上介紹了如何運用Memcached來解決系統瓶頸進而提升移動互聯網應用審計平臺系統的性能。本文基于Memcached詳細研究的基礎之上解決緩存結構設計、數據裝載問題、函數的封裝、支持Memcached大數據對象存儲的優(yōu)化工作以及對移動互聯網應用審計平臺的改進。通過優(yōu)化可以有效解決服務器數據庫成為性能瓶頸的問題,達到提升移動互聯網應用審計平臺性能的目的。最后對移動互聯網應用審計平臺系統改造前后的性能進行測試比對,通過對其測試結果的分析總結。其測試報告也進一步表明了,Memcached對解決移動互聯網應用審計平臺性能問題都具有十分重要的科學意義和現實意義。
[Abstract]:It is the need of network security supervision to trace the application of mobile Internet, audit the content of users and analyze the behavior of users, and analyze the characteristics of users' preferences and behaviors. Therefore, the project of mobile Internet application audit platform has great social and economic benefits, and can not only improve the management level of network security, Finding out the weak links and suspicious factors in the network in time and finding out the security problems can also promote the development of the mobile Internet. However, with the continuous increase of the network bandwidth, the performance requirements of the mobile audit system are becoming higher and higher. At present, the data processing efficiency of the audit platform implemented by the general technology cannot meet the requirements of big data's data processing. Therefore, the performance optimization of the mobile Internet application audit platform becomes the research content of this paper. This paper introduces the mobile Internet application audit platform, including the whole network topology, The topology of the traditional audit platform. Then the performance of the mobile Internet application audit platform is analyzed and the solution is put forward. Using cache technology to solve the problem of database performance optimization. Based on the detailed description of the technology applied to Memcached, this paper introduces how to use Memcached to solve the bottleneck of the system and improve the performance of the audit platform of mobile Internet application. This paper solves the cache structure design based on the detailed research of Memcached. Data loading problem, function encapsulation, optimization work of Memcached big data object storage and improvement of mobile Internet application audit platform can effectively solve the problem that server database becomes the bottleneck of performance. The purpose of improving the performance of the mobile Internet application audit platform is achieved. Finally, the performance of the mobile Internet application audit platform system before and after the transformation is tested and compared. Through the analysis and summary of the test results, the test report further indicates that Memcached is of great scientific and practical significance in solving the performance problems of the audit platform for mobile Internet applications.
