双网络系统间数据传输机制的研究

网络安全问题日益严峻，已有的传统方法已经不再能够满足日益增长的网络安全问题的需要，单CPU双总线安全计算机体系结构（sCPU—dBUS）从改变计算机体系结构的角度来保障计算机系统的安全性。它包含惟一的CPU资源以及本地总线和网络总线两条独立的高速系统总线；CPU连接到主总线，而总线桥接器控制CPU与本地总线和网络总线的接通与断开。研究基于sCPU—dBUS体系结构的网络结构化安全操作系统NetOS-I，它具有两个独立的操作系统子内核，分别运行于本地子系统和网络子系统。

Data Transmission Mechanism Between Two Network Systems

The traditional method is no longer able to meet the growing needs of network security,the single-CPU dual bus safety computer architecture(sCPU-dBUS) protected the calculated computer system security from the perspective of changing the computer architecture.An unique CPU resource and two independent high speed system bus(local bus and network bus) are contained,the CPU is connected to main bus,and the bus bridge is used to switch on/off the connection between CPU and local bus,as well as CPU and network b...
