This paper applies the method of observing, abstracting, problem-solving that the mankind uses in different levels of granularity in real world to the computer network routing. The authors discuss the improved OSPF routing algorithm using the granular computing method of quotient space. The paper describes the thought of granular layering and topological routing, defines the hierarchical dynamic routing (NCR) structure of cluster, domain, group, and establishes the model and algorithm of granular OSPF routing based on the quotient granular space. At last it puts forward the improved test results of algorithm simulation of hierarchical routing algorithm based on quotient space theory.

Knowledge has become an important resource in 21 century which is knowledge economic time. The importance of knowledge in social production is increasing and meaning of knowledge management research is ascended. Education field is the main position of knowledge research, transmission and innovation. The author uses the ideas, method and technology of knowledge management for reference to information-based education research field. Through the analysis of the characteristics of information-based education based on the consideration of knowledge management application in information-based education, the author mentions a new strategy which is mainly about information-based education to resolve the existent questions or which would be confront with.
