Does the hottest network management system only ca

Does the network management system only care about devices

network management is not a new concept, but users still have considerable deviation in the actual network management. Limited by the technical level of the management personnel, the investment in the management software and many other factors, many users only manage the network equipment, network lines and users, and do not establish an integrated management system on the basis of the existing network management, so as to realize the full integrated management including full fault analysis, fault location, full performance comprehensive analysis and other functions; At the same time, at the level of business operation and network management, providing users with end-to-end configuration and management based on wavelength or channel, which is convenient for the rapid response of business and the improvement of network operation level, has become the confusion faced by some network builders in management

the importance is self-evident

users pay more and more attention to network management. According to IDC prediction, the network management service market in the Asia Pacific region will increase by 20.3% from 2003 to 2007, while insight research predicts that the global broadband network management system market will reach nearly $7.1 billion by the end of 2005 and $11.2 billion by 2008

there is an old saying in China that nothing can be achieved without rules. The implication is to emphasize the importance of management, and the same is true for network information construction. Network management refers to planning, supervising and controlling the use of network resources and various activities of the network to optimize the performance of the network. Its purpose is to provide the means to plan, design, operate, manage, monitor, analyze, control, evaluate and expand the computer network, so as to reasonably organize and utilize system resources and provide safe, reliable, effective and friendly services

through correct and suitable network management, we can not only improve network reliability, but also improve benefits for the network. The ultimate goal of network management is to maximize the available time of the network, improve the utilization of network units, network performance, service quality, security and economic benefits, simplify the management and control of network operation costs in the multi system, multi vendor mixed network environment, and provide the basis for network planning

the current situation is worrying

although more and more users have begun to pay attention to network management, due to the weak awareness of network management, the size of investment, the knowledge mastery of their own technicians, the emphasis on hard and soft, and the lack of complete planning and design in advance, there are great misunderstandings among current network builders. For network management, different people have different opinions on what to manage and how to manage it

I learned from the communication with many users that many network managers only strictly manage the network equipment, lines and users, but there are large deviations in the management of the whole network and network applications. I once learned from a government user with hundreds of nodes that there are only a few people in the management center, using only the management software provided by the equipment provider

network management is not limited to this. Although the management software provided by device providers has unique features in network topology discovery, effective management of dumb devices, and providing full topology, it mainly manages the source, and this kind of management system has deficiencies in the management of other manufacturers' devices and business applications

multi party cooperation to promote development

due to management awareness, investment in network management and other reasons, the development of network management still has a long way to go. Zhang Wei, vice president of micromuse, believes that the main reason for this situation is that in the past, network builders have a sense of emphasizing hardware over software, and third-party management software also has factors such as high prices and the need for better technicians to maintain and manage. However, it has become the consensus of current network builders to carry out multi-level and multi-faceted network management on one platform, and the realization of real network management has begun to be fully launched

it is understood that digital China's linkmanager management software has evolved from an auxiliary management tool to a core management system with comprehensive functions such as collection, statistics, analysis, decision-making and processing. Through the intelligent central control mechanism integrating configuration, monitoring, collection, statistics, analysis, decision-making and processing, it actively collects specific original sample data, so as to emphasize the implementation of initiative and intelligence in network management. Zhong Zhu of Ruijie network also said that the current management software of Ruijie network is different from the traditional logical topology and hierarchical topology. It can automatically discover the full physical topology that can truly reflect the network wiring situation, and based on this, it can carry out the management of network security, configuration, performance and fault. The management objects include routers, switches, PCs, and even hubs. In terms of security, it provides rich security strategies and can cause permanent deformation of strain gauges and spring plates. Now the end is managed at the user level, rather than traditional IP or Mac, and it also provides sufficient support for the third-party management system

Huawei 3Com Shi Yang believes that in order to change the current misunderstanding of network management, from the perspective of customers, users should realize that in order to give full play to its efficiency, it must be guided by business objectives. First of all, it should solve the management problems of IT infrastructure, and timely discover the risk of network failure affecting business, so as to ensure that users' business operations are on a reliable platform. From the perspective of equipment manufacturers and ISVs, just talking about concepts is not enough. We should pay more attention to the manageability of products and guide customers by managing the practical benefits that software products bring to customers. At present, Huawei 3Com's quidview product supports integration with mainstream management platforms such as HP OpenView and micromuse Netcool

from the perspective of the attitude of users and manufacturers, the network management market will gradually mature. Although it is still in a gradual process at present, with the application oriented construction purpose of users and the increasing attention and attention of network management by users, the network construction of users will be further improved

explanation of terms

network management

is to adjust the network state in some way so that the network can operate normally and efficiently. Its purpose is very clear, which is to make more efficient use of various resources in the network, timely report and handle when the network fails, and coordinate and maintain the efficient operation of the network. Generally speaking, network management has five functions: network failure management, network configuration management, network performance management, network security management, and network billing management. At present, the network management system is mainly composed of four elements: Several managed agents; At least one network manager; A network management protocol; One or more management information bases (MIBs). Among them, the network management protocol is the most important part. It defines the communication method between the network manager and the managed agent, and stipulates the storage structure of the management information base, the meaning of keywords in the information base, and the processing methods of various events. At present, the influential network management protocols are SNMP (Simple Network Management Protocol) and cmis/cmip (the common management information service/protocol)

management software

the management software platform provides the basic management of the configuration, failure, performance and distribution of network users of the network system, which is the core of the management system. In terms of function, the management software can be summarized into three parts: architecture, core services and applications. First of all, from the perspective of basic framework system, management software needs to provide a general, open and extensible framework system. The management software can be either a distributed architecture or a centralized architecture. In practical applications, the combination of centralized management and distributed management is generally used. At the same time, the large influx of small enterprises without technical requirements caused by software is designed on the basis of the framework based on open standards, which should support the upgrading of existing protocols and technologies. And the management software should also be able to provide some core services to meet some requirements of network management. The core services should include network search, error detection and correction, support for a large number of devices, friendly operation interface, reporting tools, alarm notification and processing, configuration management, etc. In addition, it is necessary to add some valuable applications to the management software to expand the basic functions of the management software. The applications in common management software mainly include: advanced alarm processing, network simulation, policy management and fault marking

select management products follow 7 standards

business centric

keeping business centric is the most important factor in a comprehensive network management solution. It must be designed according to the application environment, business processes, user needs and the equipment it uses. In addition to reporting to the administrator that the process on the server is blocked, the traffic on the router is overloaded, or the network has bottlenecks, it should also be able to take initiatives through policy based network management, Send an alarm to relevant personnel, and display the process that the thermal deformation temperature of the affected business is 200 ℃, business departments and even individuals

provide environment for application software and services

the key task of network management is to ensure that the network and its components can provide the resources required by applications and users to complete business processes or transaction processing, and must also provide different service levels according to different industries. It must be able to provide network administrators with management methods that are crucial to them, as well as meaningful data queries

the combination of availability, scalability and ease of use

availability and device status, accessibility and network topology, performance measurement and management are all components of today's network management. Performance measurement should be integrated into and closely cooperate with comprehensive network management solutions, and scalability has become an important standard for users to choose network management solutions. A complete and powerful solution must be simple, intuitive, easy to use and consistent, so as to improve the efficiency of development

performance price ratio

while ensuring high performance, bandwidth and security, it is also necessary to maintain the accessibility and simplicity of the system. A comprehensive network management solution must be not only powerful, but also efficient, with low cost, development costs and hardware requirements

standard support and protocol independence

network management solutions should support existing or even emerging standards and incorporate them into their own architectures. Support not only SNMP, but also DHCP (Dynamic Host Configuration Protocol), DNS, DMI (desktop management specification) and CIM (Public Information Management). In addition, it must also support all network protocols and be able to run on various types of hardware and operating systems, not just close to a manufacturer or an operating system

for traditional support

traditional platforms must be supported. Many enterprises also rely on these environments to work. Without these powerful traditional platforms, enterprises will suffer huge losses. Traditional support will ensure that NT, UNIX, and host environments will be managed in a business focused, consistent, and simple manner

integration and flexibility

must be able to easily and closely integrate with the managers and tools of some special devices. It must be able to start the tools of special equipment in its own network environment, and provide flexible methods to exchange information with these tools. Any network management solution must be able to adapt to the special needs of customers and the sudden changes of major businesses. Tube software should be flexible
