Computer Network Reliability Optimization Design Question Research

With the computer network rapid development, the computer network reliable question more and more receives the network designer, the constructor and user's universal attention. The computer network reliability also becomes the weight computer network overall performance item and its the key technical specification.The paper first elaborated overseas regarding the computer network reliable research present situation as well as our country in this domain development background, the research advancement and the realistic situation. The computer network in domain application and so on the school, factory, enterprise, bank, traffic, energy, correspondence, military is day by day widespread, as the people daily life, as big is as slightly stable as the national security. Therefore, the computer network reliable research topic has the huge economic value, the social value and the social benefit.The paper next introduced the computer network reliable related theory, analyzed the influence computer network reliable many factors, point out the restriction computer network reliability enhanced bottleneck question. Above this foundation, the paper proposed the computer network reliability optimization design concrete plan, established correspondingly the computer network link cost model and the computer network reliability model, separately used the genetic algorithm, the artificial nerve network, the fuzzy nerve network and so on three kind of intelligent algorithms carries on the solution to the computer network link cost model and the computer network reliability model.The paper expert in the known alone one kind of computer network, the concrete computer network link cost model and the computer network reliability model which in the practical writing establishes, and uses the genetic algorithms, the artificial neural networks, the fuzzy network nerve and so on three kind of intelligent algorithms carries on the simulation. Carries on the quality synthetic evaluation to the known many kinds of different computer network reliable target system, has produced the appraisal result. In the simulation process, uses has the fine performance the engineering simulation language Matlab7.0 and the function toolbox,carries on the programming to solve, and by graph form feedback final simulation result. The simulation result indicated, in the paper establishes the corresponding computer network link cost model and the computer network reliability model is suitable, model algorithm and programming language selection is effective, the paper proposed the computer network reliability optimization design concrete plan has the practical application significance.
