[软件开发] Reliability of Computer Systems and Networks

[book]bName=Reliability of Computer Systems and Networks: Fault Tolerance, Analysis, and Design;bAuthor=Martin L. Shooman;bISBN=0-471-29342-3;bPub=;bVer=2002;bLang=;bFormat=pdf;bCover=http://www.itepub.net/book.gif[/book]The central theme of this book is the use of reliability and availability computations as a means of comparing fault-tolerant designs. This chapter defines fault-tolerant computer systems and illustrates the prime importance of such techniques in improving the reliability and availability of digital systems that are ubiquitous in the 21st century. The main impetus for complex, digital systems is the microelectronics revolution, which provides engineers and scientists with inexpensive and powerful microprocessors, memories, storage systems, and communication links. Many complex digital systems serve us in areas requiring high reliability, availability, and safety, such as control of air traffic, aircraft, nuclear reactors, and space systems. However, it is likely that planners of financial transaction systems, telephone and other communication systems, computer networks, the Internet, military systems, office and home computers, and even home appliances would argue that fault tolerance is necessary in their systems as well. The concluding section of this chapter explains how the chapters and appendices of this book interrelate.
