Reseach On Marching-on In-time Scheme And The Fast Algorithm Of Time Domain Integral Equation

Companies face the increasing information needs, for enterprise’s IT operations work put forward higher and more stringent quality requirements.The operations of the software on the market at present is basically informatization equipment and connectivity is given priority to, in the face of users to a large amount of data the physical problems, particularly the data link facilities, it is difficult to monitor and management.With ITILv3 management thoughts in this paper, in combination with kei igawa the company’s actual situation, the network computer configuration of the physical database(CMDB) and the corresponding work order and change the process design and implementation are studied.Thoughts and methods of the research is based on domain driven design, by the workflow engine, no database and rapid prototyping interaction as the main technology of research and development, with the UML2 as design ideas, adhere to the agile development process in the implementation process, to satisfy the business enterprise data data link the physical facility operations management as the basic goal, construct a model conforms to the modern operational management link operational implementation of the system.This project is carried out in accordance with the kei igawa the company’s operational requirements, for more dispersed, large area of enterprise to carry on the design, according to the requirements of the construction of CMDB, in the configuration items into the building, room, computer room/wiring rooms, cabinets, distribution frame/panel, jumper, workspace, data module, relay equipment units, access units and so on, defines the relationship as interconnected, containing, is located in the and so on, connecting link form is given priority to with all kinds of fiber optic cable, copper, maintenance shall be conducted by operations staff.Found in the study, to safeguard the CMDB in the process of the operational effectiveness and timeliness, the system must provide change initiated by the front desk and fault handling processes, including single distributing and registration of change.For the operations of the data link, complete configuration database is needed to provide support for troubleshooting and optimization.System implementation using Ruby on Rails in research and development, and introduces AngularJS front frame, and thoroughly implement the business area and realize the separation of interface, all areas of the business use the Restful Service returns JSON data information interaction, but also for future integration into the whole operational framework provides support.In order to adapt to different management unit and fault handling process of the change, we also adopted a Ruote workflow engine, although we do not implement in our implementation graphical configuration, but its flexibility can meet the needs of the business.In the user management and organization management, library user accounts associated with the enterprise namely, integrated single sign-on.In this paper, through research and implementation demonstrates the operational management of the data link layer, must focus on the CMDB, the difficulty of data link monitoring feature enables us to focus on troubleshooting and change processes.Through Ruby achieve business API, front-end HTML invocation style, also proved that the operations of enterprise information system may be more language in the future, highly loose coupling software architecture.
