Research And Implementation Of Integrated Network Active System Based On EAI

The technology of Enterprise Application Integration (EAI) is an very wide subject. INAS mainly realizes and simplifies the interrelation among the different structure systems, solves the problems of major enterprises, which have many kinds of applications but lack of effective communications among them. The technology of EAI has been used in many industries, such as telecom, bank, and transportation systems.The Integrated Network Active System(INAS) mainly uses EAI technologies. INAS combines the business flow, application software, hardware with every kind of standard , and integrates every Network Active platform to an Integrated Network Active platform. INAS presents a 4-tier distributed architecture based on EAI, and realizes the integration of flow automatization, worksheet active and the loose coupling of dispersive systems.Firstly, the disadvantage of GuangDong Telecom is given in detailed, then the important and advantage of INAS is analyzed. INAS mainly completes telecom system tasks such as order management, flow dispatch, network active and unified control of the active flow, and solves every kind of dispersive system which has many disadvantages. This picks up the active speed of each business, provides effective and high quality active services by taking customer as center.Secondly, this thesis presents a 4-tier architecture based on EAI as the main guiding idea. and discusses the main technologies which are applied in INAS. According to actual demand of Telecom Operation Support System (OSS), INAS uses many technologies of J2EE platform to design and realize Application layer and Enterprise gateway layer, uses groupware and workflow technologies to construct Frame layer, and builds Support layer by many substrate servers. It describes the function and software structure of Application layer, Enterprise gateway layer, EAI Frame layer and EAI system support layer .Finally, this thesis gives function description of INAS modules which are designed based on EAI. We give the detailed design and implementation of worksheet receive-sending module, worksheet processing module, net module and system supporting module. This thesis also describes the performance optimizing process of INAS, and proposes several optimize performance methods, which shows high speed in business data process and stability ability of INAS.
