| The management of modern fiber-optic network is a complicated process of system analysis, management, control and decision which needs a powerful information supporting system to communicate each independent business operation handles system, in order to realize the ability of comprehensive analysis needed by scientific management in modern fiber-optic network. But current operation and management system of fiber-optic network management business is a huge system compose of some disperse, independent, isomeric computer information management system. While a great deal of various information needed by fiber-optic network management is accumulated in it, the great amount of information becomes "ocean of data", unable to sustain analytic needs by modern fiber-optic network management as a result of no set of valid methods of management and analysis. Therefore, on the condition of information society, it is a huge challenging question how to gather these disperse, independence, and isomeric operation and management system of fiber-optic network management business, put forward valid management methods of fiber-optic management data of huge capacity, make the best use of the data potentials, increase management level and efficiency of fiber-optic network, and lower the management cost.Many information in the optic fibre network all correlate with space attribute, GIS, as a kind of effective way of managing space datum, have congenital superiority in managing resource of optic fibre networks. This has offered abundant necessity for introducing GIS to manage the network resource of optic fiber.It is a heavy and complicated project to develop the network resource management system of optic fibre based on GIS. So here is a lot of argumentation of various fields involved. This article is unable to narrate totally as space is limited. Describe only the fuzzy localization model and realization used in general design and system.The structure of the network resource management system of optic fibre adopted C/S framework of three layers. The advantage of three layer structure:Security enhancement. Use server separate customer from database server, customer end can visit database server directly. Efficiency improves. In three layers of C/S structure, the chaining between customer end and application service is only some simple communication protocols in fact, and the establishment or driver that have dealings with database server and need, come to undertake by the application service, this has lightened the burden of the customer end, has reduced chaining the cost of the database server too, make database server absorbed in data serve instead of and application program of customer end exchange frequently. Easy to maintain. Because use logic to be sealed and has been put into and used in the server, so, when use logic to change, only need to revise and use the procedure in the server, the application program of the customer end needn't be upgraded, the cost safeguarded is reduced greatly.The elasticity. Three layers of structure are cut apart clearly, each independence in logic, and can realize alone. Because they are logic was divided, might not be corresponded with the physics position, so their hardware system is formed it is very flexible, every part can be chosen instead of dealing with load and dealing with the hardware that the characteristic adapted to. Sharing. The individual application server can provide service for the application program of customer in different positions, namely use the system to be only written once and can be used in each environment.Opening. Because use each package of the server to have standard interface, users can rewrite one's own customer end procedure and one's own browser procedure.The system can roughly be divided into several modules:Manage the geographical attribute moduleSystematic function moduleCount and inquire about the moduleManage various kinds of circuits and equipment information moduleDecision support moduleFuzzy space this article expoun... |
