Analysis and Prediction of Message Mechanism in Microkernel Operating System
Zhi Wang · Computer Communications · 2005
Taking the microkernel operating system Minix as an example, this paper explains the message mechanism of modern microkernel operating system, analyzes its design concept and implementation, and point outs its importance in the operating system. It also proposes that the object of message mechanism is a complete message sending/receiving procedure (including sending, receiving and one-time process scheduling). Furthermore, the paper presents a method for Minix message performance evaluation, programs source code and performance evaluation results. Finally, the paper gives several suggestions on how to improve message mechanism performance of microkernel operating system.
