| Abstract: | Security and survivability are important requirements of dedicated computer system. The legacy embedded operating systems with microkernel 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. |
