With the maturity of Java and web technologies and their wide application on the Internet, network management technologies and models have ushered in another revolution. In the field of network management, by integrating the network management system through Web technologies (such as Web server, HTTP protocol, HTML and Java language, etc.), simple and effective management tools that can run on various platforms can be obtained. In particular, people's requirements for computer network management tools are not only limited to centralized management mode, but also require network management tools to have distributed computing capabilities. In recent years, with the development and maturity of Java, EJB, XML and other technologies, people's distributed requirements for network management have become a reality.
1. Features of Web-based Network Management Mode
- Distributed: There is no geographical restriction, suitable for distributed network management.
- Cross-platform: Network administrators can access the network from any computer on any platform, which solves the interoperability problem caused by multi-platform heterogeneity.
- Low cost: The interface is more friendly, the management method is simpler and more convenient, and the network management cost is reduced.
- High efficiency and good security: The thin client/fat server mode is adopted, and a large number of heavy computing and storage tasks are handed over to the Web server, which improves management efficiency and enables users to operate the network management system more flexibly. At the same time, with the help of WWW security The mechanism can effectively perform access control, data encryption and server authentication.
2. Advantages of localized network management software
2.1. Localization Advantage 1: Ease of Use
Many domestic software have realized the full Chinese interface in recent years, and can be used without special training. The implementation period is short, and there is no need to install agent software on the monitored server. The user can basically complete the implementation in about a day after purchase, and the operation and maintenance are very convenient. However, foreign large-scale network management software requires a professional technical team to manage ("network management software for network management software"), which requires a large investment, a long implementation period, and relatively troublesome operation and maintenance.
2.2. Localization Advantage 2: Customized Service
Large-scale foreign network management system is a general network management product, which is difficult to meet the needs of enterprises for special application monitoring. It is difficult and expensive to require large foreign companies to carry out secondary development of their products for domestic enterprises. Domestic software can usually provide source code-level technical support, which can be quickly customized and developed for the special application of enterprises.
2.3. The third advantage of localization: cost performance
Foreign large-scale network management software has excellent performance and correspondingly high price. However, in the specific application environment in China, it is often difficult to fully display the power, and the performance advantage is greatly reduced, so the cost performance is dragged down. The domestic software has unique advantages in this regard. Today's China's network management software market has transformed from an initial manufacturer-led model to a market demand-driven model. The market has basically matured, and users' purchasing behaviors are becoming more rational, and the requirements for products and services are more stringent. Without timely insight into changes in user needs, manufacturers that provide network management software products that conform to the development trend are difficult to survive in the fierce market competition.
3. Realization of localized network management based on Web technology
At present, with the popularity and development of Web technology, Web-based network management technology is widely used in network management. There are two commonly used web-based network management technologies: one is based on embedded network management, which embeds the network management workstation into the network device, each device has its own web address, and the network management personnel can access it through a browser. Management equipment, this technology is suitable for small network management systems, and is not conducive to expansion; the second is agent-based network management, the agent program manages the equipment, loads the management program into the network management workstation, and communicates with the agent program through the SNMP protocol. , the browser communicates with the network management workstation through the HTTP protocol or other methods. This technology enables the browser and the network management workstation to use the B/S (Browser/Server, browser/server) structure to communicate, software system deployment, upgrade maintenance and data The backup only needs to be done on the server side, and the client does not need to install and debug the application, which greatly reduces the total maintenance cost of the system and strengthens the stability and scalability of the system.
