The Study Of Distributed Operating System E1 Based On Second Generation Microkernel L4

This paper mainly studies the distributed operating system E1 that based on secondgeneration microkernel L4This paper first discuss the problem that microkernel must and can be smell, and the fallof the first generation microkernel's design. The result means that based on secondgeneration system can get good performance. After that paper study the two versionsecond generation microkernel - Exokernel & L4, and get some difference of them. Theresult means that the L4 have property abstraction concept - address space & thread,more fit system to extensible, the system based on it will have good modular. Thesestudy also answer the question that why E1 selected L4 as system kernel.Since E1 is a kind of distributed operating system, paper studies the three successsystem that based on first generation microkernel - Amoeba Chorus Mach. From sixaspects compare the three systems to make prepare to study the E1 system.Paper's fourth sections make a deep study of E1 that based on before sections preparestudy work. After the study architecture design of E1, make a simple implementation ofE1 system core concept distributed objects; get several experience of architecturedesign.
