内容説明
Load distribution has always raised the interest of the research community and industry, however, it has never resulted in wide use. One of the main reasons is the lack of widespread distributed operating systems. This book describes yet another attempt to receive load distribution, this time in the context of the Mach-mikrokernel. A new level, on the top of the mikrokernal, is suggested and described through detailed design and through performance measurements. Advantages and drawbacks are discussed.
