Studying The Fault Tolerate Strategy For Component-based Software

For most software engineering methods that not only promise to increase already high quality, costs are easier to predict than effectiveness. But costs or values are so important, even in the strategy control. Fault tolerance is no exception. The grading of the methods of Software fault tolerance, used in different projects can maximum the value of a software product. This thesis aims to analyze and discuss fault-tolerant techniques of component-based software system.This thesis analyzes and research the idea of the foundation of the software engineer, research and analyzes .NET component development technology, and software system topological architecture, Combine with development experience of constructing distributed component, research fault-tolerance strategy base on software system of development component, present classification management and choice,data dynamic copy,loading balance,online upgrade,power management. Combining these strategy application, present a kind of software fault tolerance design thinking, giving a software design modle.The thesis combines the example of SD air-logistic import and export business process system, using reliable technical index and gains mensurable analysis.
