Program overview
Provide a centralized and distributed metropolitan area network platform, education management data center, education integration interconnection center and network security management platform solution. The establishment of "infrastructure" describes the relationship between different teaching systems and processes. The typical architecture shows based on The establishment of systems and processes required for future system expansion and business development, including multimedia storage, data warehouses, support systems, and security systems.
1. Centralized and distributed MAN
· MAN mode (centralized)
Networks are built within the region, centralized management is implemented, and data is stored on the server of the Education Commission. The school does not need to purchase expensive server equipment, and can access the central website through a browser.
In the centralized idiom network mode, only a series of software (Education Committee management system, school management system, teaching resource system, network assessment system, video application system) including "K12 Netcom" should be installed on the website of the Education Commission Center Complete metropolitan area network application.
· Metropolitan area network model (distributed)
In the distributed metropolitan area network model, the education committee server and school server can achieve distributed management, school data is stored in the school server, and education committee data is stored in the education committee server; multi-level management of the education administration department (such as the municipal education County Education Commission, etc.). The education committee and the school respectively adopted "K12 Netcom" to establish a homepage, hooked up management systems of different levels, and transmitted management information through an online data connection.
K12 teaching resource system, network assessment system, network video system, etc., can be placed on different levels of websites according to the degree of sharing. In order to meet the demand of high access volume of the metropolitan area network and solve the problems of high load and high bandwidth of the server, K12 also adopts advanced server load balancing technology, so that users can enjoy high-quality network services.
Network logical structure
Generally speaking, the core part of the metropolitan area network application software will be installed in the data center for each sub-node to access. Because there can be only one application software, the data center is often composed of a series of server clusters.
As can be seen from the figure, the server cluster combines Web server, database server, mail server, resource server, video server, and network storage device in terms of application functions, and distributes application services to different servers.
Network logical structure
The data backup center is also composed of a server cluster, and the main application services in the education metropolitan area network are moved to the backup center. Once the main site of the data center is busy or the network fails, the backup center will undertake the entire external application service. Although the data backup center is not necessary in the education metropolitan area network, the data backup center should be established from the perspective of safety and reliability in areas with high requirements or conditions.
WebSphere Application Server (WAS) is the core hub of the entire basic platform, and it provides basic services such as scalability, efficient performance, reliability, and security for electronic applications at all different levels.
2. Due to the current rapid development of information technology, the education integration and interconnection center has increasingly complicated the business environment of various education management departments, and the continuous increase of various business data has made the various types of data in the education management department and the data sources also very scattered. Users are increasingly looking forward to unified and related management of data from different data sources and data types in the entire education management department. However, at present, many education management departments are constrained by various factors. It is difficult for scattered and different vendors' data sources to be copied or concentrated into a single database. Users are eager to obtain a solution that can integrate various distributed data sources in the education management department to facilitate access to diverse data. IBM Information Integrator can provide unified integration of relational, structured, and unstructured data throughout the education management department.
Information conversion is one of the key parts of this system. Its mechanism and capabilities are directly related to the communication between this system and other related systems, and even more related to the availability of the system. Since this system involves contacting and extracting data with many different government agencies, this requires a convertible information format and information routing mechanism. If this mechanism is not used, the system should implement a one-to-one interface with different related systems. This greatly reduces operational efficiency and wastes resources. We recommend using an intermediary design methodology to provide this conversion mechanism. This information conversion mechanism should provide the following functions:
The format required by the system or another format can be converted from any system information format.
In the conversion process, there is no need to provide a private application interface to the counterparty system. The other party only needs to provide the information format, the system conversion mechanism can be converted.
During the conversion process, this mechanism can provide a business rule operation mechanism; when converting information, the system can convert the other party's information to comply with the business rules of the system. Thereby, the collected information is stored more optimally and processed efficiently.
This solution also provides visual tools to provide information conversion rules. No programming is required.
3. Education Management Data Center
IBM's Insight at School is a database platform designed specifically for Chinese basic education administrators and educators. It is a database platform customized for Chinese basic education customers on demand. It provides principals, teachers, and students with data transmission based on real-time functions including student registration , Attendance, updating student numbers, browsing purchase data, and also providing management information including school and district student attendance numbers, financial reports, and teacher certification. Education committees, schools, teachers, public institutions, etc. get valuable information to help them make decisions to improve the achievements of students, schools, and education committees.
The program complies with national and regional education standards, and an open architecture uses a data warehouse to improve educational performance. The data warehouse allows all education managers to integrate relevant data and information to display statistical charts. Schools can also let teachers understand detailed student test scores, grades, and attendance. Rate, course selection and more student information.
4. Network Security Management Center At the same time, IBM's Tivoli system management and security management solutions serve customers in the education industry 7 * 24 hours, fully embodying reliability and security assurance.
Such a large-scale and complex-structured network requires a powerful and reliable network management platform to effectively manage the network topology, network nodes, network equipment, network failures, network performance and other aspects. Tivoli NetView, as the industry's most famous network management software, can provide comprehensive management capabilities:
Network topology management: automatically discover the nodes of the IDC network and generate a network topology map, monitor the network nodes and network connection status in real time, and be able to classify and manage specific network resources.
Network performance management: Automatically collect important network performance data, such as: IP traffic, number of error packets, number of discarded packets, snmp traffic, etc., and set the corresponding threshold, when the collected data reaches the threshold can trigger an alarm or defined automatic operating. You can display these network performance data changes graphically, or you can store these data in a relational database system for easy retrieval and analysis.
Network fault management: Network event management is an important aspect of network management. Tivoli NetView has a powerful network fault event management capability, which can timely collect fault events on the network, classify, filter, alarm, automatically respond to and correlate related network events.
Network equipment management: The network management platform can also support industry-standard APIs and can be easily integrated with the equipment management software of major network equipment manufacturers, such as: CiscoWorks, 3com Transcend, Bay Optivity, etc.
