基于嵌入式μCLinux路由器的防火墙设计——科学技术学院网络教学接入设备的设计与实现

Fire Wall Design On the Basis of Embedded μClinux Router——The Design and Realization of Online Education Access Equipment in College of Science and Technology,Xinjiang Agrecultural University

新疆农业大学科学技术学院网络接入设备的设计基于ARM处理器的硬件构架,通过移植μCLinux系统建立嵌入式开发平台,针对Linux内核模块进行功能扩展设计和优化,设计并实现了集路由功能、防火墙功能、流量控制功能为一体的网络接入设备,有效的弥补了当前各类厂商不同型号防火墙的不足之处。

The design of the firewall is as follows,embedded system development platform was set up through the μCLinux transplantation and on the basis of the arm processor hardware architecture.The extensions module of the Linux kernel were designed and optimized,the application layer data flow control and the large flow of data payload were researched and the design costs was reduced greatly.So it effectively makes up for the current various manufacturers of different models of the inadequacies of the firewall.
