Analysis of constructing large-scale trans-regional network management

Background analysis on the construction of trans-regional network management at present, due to the relevance of work and the extensive distribution of resources, a large number of enterprises and institutions have deployed decentralized, cross-regional network system, which has put forward a considerable challenge to the overall network construction. This paper comprehensively considers the present situation of network management and the future management mode, the planning and guarantee of the network management system, the network management of professional equipment and the collaborative management requirements of the general equipment network management, the multi-level management rights and the definition of management interface, etc. The current situation of trans-regional Network Management The network environment of the domestic Cross-regional network unit is different, but also has certain commonness, the following this network environment construction, the deployment and the application situation may do the typical explanation network system: generally has the three level structure the business backbone network (satisfies the WAN connection or the virtual private network connection), To achieve the completion of regular data management and exchange work, to achieve national, regional (and professional), data Access node-level network interconnection, the realization of a sound network infrastructure management to ensure that the network system stable, efficient and safe operation. Application system: Including Office system, business system, video conferencing system applications and so on. Server and Storage System: to achieve the national, regional (and professional) and data Acquisition node network data processing and storage and disaster recovery needs, to achieve the entire organization of data resources, computing resources, unified management and sharing of utilization. Network security system: To achieve the system construction, management measures, technical means, such as a full range of information security system, construction, including the overall network of security protection system, risk assessment, vulnerability detection and system strengthening and prevention measures. In general, a large scale network deployment, the backbone network system is in the existing network infrastructure based on the construction and improvement, the backbone of the tree topology structure, improve network bandwidth and reliability while optimizing network traffic and operating costs. For many large-scale network distribution units and institutions, the network construction is not the same, but according to its distribution characteristics and business characteristics to deploy. For example, depending on the business characteristics of the units in a network system, at the same time, to ensure the stability and efficient operation of the network, the backbone structure will be localized management, mainly using three-layer structure: core layer, convergence layer, access layer, corresponding to the first-level node, two-level node and three-level node. The problem of trans-regional network operation is a difficult task, the construction of basic hardware, the perfection of business system and the standard of IT service should be incorporated into the construction and perfection of the whole network system. Network coverage of such a large scale, with the increasing of the application of IT hardware and software, the work pressure of the system managers will be more and more, while the organization unit has high requirements on the stability, reliability and service quality of the network, and the input and increase of a large number of hardware and software have caused the difficulty of network management to increase. The overall problem can be categorized into the following aspects: first, in the day-to-day management of network systems, IT infrastructure failures and performance monitoring is a very important link, it is the network system stable and reliable guarantee. To protectThe network is unblocked, the network management personnel needs to carry on the 7x24 monitoring to the existing net equipment, the link and the various operating system server, reduces the network administration work the complexity, enhances the network management the efficiency. Secondly, the unit needs to monitor the overall operation of the database and other application systems, and it needs to discover the potential problems in time, which is a great challenge to the network management engineers. Network management engineers in the past often in the failure occurred before the processing, the work is in a passive state. Sometimes even if a fault is found, it takes a long time to find and diagnose the fault, which greatly affects the work efficiency. Because there is no intuitive network topology function, the application system monitoring and management is very cumbersome. How to effectively monitor and manage all kinds of application systems, continuously improve the service quality of various applications, and the problems that the system management personnel need to solve. In addition, with the continuous improvement of various business systems, it is necessary to grasp the healthy operation of its business system in time, it is necessary to monitor the running condition of network equipment, server system resources and application software, and realize the centralized and unified management of the network, so as to grasp the performance of network system as a whole. How to construct the network system management plan How to solve the problem of network administration without changing the net structure and network infrastructure, become the problem that the IT operation and maintenance manufacturers want to solve now. Units will be based on their specific needs to continue to build and improve their own network system. For the large-scale network of enterprises and institutions across the region, it is the leader of the IT movement Dragon technology to put forward a set of special for large-scale cross-regional network solutions. Group management strategy because of the huge structure of the trans-regional Network application platform and the variety of equipments being monitored, it is necessary to coordinate a set of group management strategy to manage, so it is very helpful to find, manage and monitor the equipment, and the network management personnel can see the logic and management level at a glance. Using Dragon Technology's Siteview ECC as an example, an enterprise or organization may be in a certain period of time to adjust system upgrades, when the system may stop service, you need to siteview ECC on the entire department of all server monitoring to avoid unnecessary alarm information. If you place servers from the same department in the same group, you can configure the entire group to start or stop the monitoring service. There are several ways to manage groups, grouped by device type, or by administrative rights for administrators. For the complexity of the network characteristics, in order to facilitate management, according to the device type to group. The same equipment is grouped into one management group, significantly reducing the complexity of management. Remote management control because of the large scale distribution of cross-regional networks, it is a priority to understand the operation of different regional equipment and control the management of different regions. The software with b/s structure can satisfy these conditions. The software based on B/s architecture is completely not restricted by the region, so as long as the Internet can be viewed. Take the Dragon technology product line for example, SThe most advantageous aspect of Iteview DM is that it can be managed remotely and can be monitored and managed remotely by the monitored equipment. Careful monitoring can be done on the PC side, which is fully integrated into the monitoring range. For example, a new computer installed a running program, Siteview DM can immediately capture. Not only that, if a PC is plugged into a USB storage device or the CD-ROM is placed on a disc, the desktop management product can be locked freely, and even can lock a group of all the computer's keyboard or mouse. Clear all equipment to ensure the smooth network, network equipment monitoring and management is essential, the entire network system of thousands of network equipment must be included in the scope of monitoring. And such a large-scale network system, the network equipment must be complex, network administrators on the Internet system, links, equipment management also feel powerless, often have the feeling of powerlessness. The network equipment Siteview NNM can automatically the physical topology diagram of the component level, discovers the network equipment in the multithread way, and can quickly discover the large number of devices. For hundreds of network devices in the network, Siteview NNM did the monitoring. Cross-geographical enterprises and institutions every node of the entire network is monitored, and from the node to the server, network equipment, workstation layer search down, until the end of the PC. From "pay" to "Thewa" have done a comprehensive search and monitoring, fully present the entire network. In the first time, the fault location is found, the fault is solved quickly, which not only saves a lot of time, improves the work efficiency, but also transforms the IT operation from passive to active. Create Network Management system users: the development of network Management System User table, and the user's level of authority to make division, so that operators can only be within their purview of the equipment monitoring and management. User Management module can add, modify, delete users, but also to different users to give different permissions. The Siteview ECC highest level system administrator can configure different user names, passwords, and permissions for other system administrators. The permissions settings cover all the features of Siteview ECC, including monitors, alerts, reports, and diagnostics tools. Different system administrator with different user name and password login system, see may be completely different monitoring content, can operate on the system is not the same, the system management responsibilities of different people have different rights and responsibilities are clear, conducive to the standardization of system management. For example, you can set up a user for the enterprise non-information management department, allowing him to view only the operation of the application monitoring, not the network management system. With the economic globalization and the formation of large factories in the world, the application will become more and more common, and the complex and huge network management will be improved constantly, and gradually improve the trans-regional network operation and maintenance!
