多用户并发方式的网闸实验系统设计

当前网闸的应用越来越广泛，为了让学生掌握网闸的原理和应用，该文提出了一种基于Linux平台的，结合C、PHP、JAVA、SQL语言开发的，具有安全策略审查与数据摆渡功能的模拟网闸实验系统的设计方案，并开发出基于B/S模式的多用户并发网闸实验系统，使每个用户能够独立地通过WEB网页完成网闸功能实验，并从中能够深入了解网闸技术原理，达到实验目的.

The design of GAP experimental system with multi-user concurrent mode

With increasing applying emphasis of security gaps, its theory and utility have become a necessity to students. To remedy this deficiency, this paper propose a design of a gap simulating experimental system, which is based on Linux system and developed with C, PHP, JAVA, SQL language in blend, that can fulfill functions of security policy checking and data ferrying. This system is developed supporting multiple accesses based on B/S mode, which facilitates clients to access the service via WEB respectively, thus get a thorough understanding of gapping theory to achieve our original intention.
