The Design And Implementation Of The Virtual Firewal For Data Center

With the popularity of cloud computing and big data, virtualization technology has been widely used, Virtualization technologies including server virtualization, storage virtualization, and network virtualization. We want to discuss server virtualization today, it is the multiple physical servers into a pool by using virtualization software. Through a network connection, to form a virtualized environment. In this virtual environment, use virtualization software virtual multiple virtual systems in a virtual environment, each virtual system to provide one or more foreign service.In this paper, we use the methods of software engineering for detailed analysis and design of the data center virtual firewall programs.First, this paper introduces the development background of the data center virtual firewall program, and the urgent problems in the current environment. We described the findings and solutions in virtualization security both domestic and foreign.Then determine the needs and the system needs to reach the target user needs analysis through needs analysis.Secondly, after the completion of the demand analysis, we followed the system architecture design. In the architecture section, we present the design goals and principles based on the system requirements analysis before. After the completion of architectural design, we begin to detailed design, detailed design of the system is divided into detailed dysign of the system and database design.Third, we introduce the realization of the core module. We describes several major features specific implementation process, given a lot of the code and the map. Then, the system was tested by several test cases to test the system core module.Finally, we summarized the data center virtual firewall programs. And proposed the project at this stage problems and the part for improvement in the future.
