P-Bus, a new programming interface layer for safe kernel extensions is proposed. P-Bus introduces a new programming interface on top of the Linux kernel in order to give formal specifications to the interface, and to improve portability of extensions. New extensions, called P-Components, are verified with a model checker MKencha to see whether a component is compliant with rules which should be obeyed...
Although recent high-end interconnection network devices and switches provide a high performance to cost ratio, most of the small to medium sized PC clusters are still built on the commodity network, Ethernet. To enhance performance on commonly used Gigabit Ethernet networks, link aggregation or binding technology is used. Currently, Linux kernels are equipped with software named Linux Channel Bonding...
This paper introduces a new dependable operating system project, called DEOS, started in 2006, and scheduled to continue for six years. In this project, a safety extension mechanism called P-Bus is to be designed, and implemented in the Linux kernel so that a future dependability attribute is implemented with P-Bus. A hardware abstraction layer, called SPUMONE, is introduced so that a light-weight...
Although recent high-end interconnection network devices and switches provide a high performance/cost ratio, most of the small to medium sized PC clusters are still built on the commodity network, Ethernet. To enhance performance on commonly used gigabit Ethernet networks, link aggregation or binding technology is used. Currently, a Linux kernel is equipped with a software solution named linux channel...
