Research On Communication Network Model For Jiangsu Rural Credit Cooperative Union

As one of the first experimental unit in the national Rural Credit Cooperative Union (RCCU) , the behindhand in E-banking construction and poor managerial mode in Jiangsu RCCU becomes the main bottle-neck, which restricts the RCCU's business fine development. So, it is necessary to establish the communication network system which covers all over Jiangsu Province and is safe, reliable and meets the application of the Jiangsu RCCU's business.In this dissertation, the study has been made on the base of communication network's construction-model in the field of Jiangsu RCCU. The main contents are summarized as following:1. The frame and characteristics about internetworking model used in commerce banks were analyzed. The contrasts were given between the commerce banks and Jiangsu RCCU in E-construction.The research intention, significations were expatiated.2. The mathematics model on how to choose the backup line was constructed by means of Fuzzy Comprehensive Evaluation(FCE) and Analytic Hierarchy Process(AHP).The conclusion has been made: ISDN was the best backup line in the long-distance internetworking by synthesizing the factors of economy , line-coverage and network-performance.3. By using Analytic Hierarchy Process(AHP), a communication network model based on the Frame Realy technique was put forward. Meanwhile, the mechanism of handle-time-lateness was analyzed, the deal-time-lateness was estimated and the reliability based on the Frame Realy network model was studied.4. SDH communication network model was discussed. The system frame and reliability about the SDH communication model were researched. The performance and cost were contrasted between the Frame Realy communication model and the SDH model. The result based on the SDH reliability's research has given a theoretical foundation for RCCU to establish their communication network platform used for data-centralization.5. A hybrid communication network model was researched. By means of analyzing the model's cost-constitute, a mathematics formula about the hybrid communication network cost was given, and the formula's significance and its intention were described in detail. A series of hidden security-trouble in the hybrid network model were analyzed. A home-bank application instance was given, in which the safety-control manner was...
