一种可容忍代码错误的专用计算机系统模型

A fault-tolerant dedicated computer system model

提出一种新的计算机体系结构模型——超内核系统模型,使专用系统可以容忍代码错误,提高可生存性.并且实现了一个超内核系统开发平台,完成了网络防火墙原型系统.该网络防火墙原型系统在同样的硬件平台上比优化的Linux防火墙包转发延时少大约20%.

Security and survivability are important requirements of dedicated computer system. The legacy embedded operating systems with microkemel suffer from lacking of these desired features. In this paper, we propose ultra-kernel model to make dedicated system tolerant code bugs and improve the security of system. We have implemented a prototype firewall system based on our ultra-kernel design in a developing environment. Measurements show that, latency at 10Mbps of ultra-kernel system is about 20% better than at Linux system on the same hardware platform.
