本篇essay代写- Computer network management technology讨论了计算机网络管理技术。网络管理主要是对网络通信服务进行监督、组织和控制,对信息进行处理等。网络管理技术是网络管理员通过应用网络管理工具对网络上的资源进行监视、配置等,从而保证网络和网络设备的运行,使用户的需求得到满足。根据国际标准化组织对网络管理的定义,一个标准的网络管理系统需要定义系统功能、网络资源的表示形式、网络管理信息的表示和系统的结构。本篇essay代写51due代写平台整理,供大家从参考阅读。

Computer network management technology,计算机网络管理技术,essay代写,代写,paper代写

Network management is mainly to supervise, organize and control network communication services, and to deal with information. Network management technology is a network administrator through the application of the resources of the network management tools for network monitoring, configuration, testing, analysis, control, evaluation, allocation, scheduling, etc., thus ensuring the reliability of the network and network equipment operation, stability and efficiency, the user needs are met. According to the definition of the international organization for standardization of network management, a standard network management system need to define the system function, network resource representation, the representation of a network management information and the structure of the system.

Computer network management can be divided into five types: performance management, configuration management, billing management, security management and fault management. There are two main types of computer network management protocol, SNMP and CMIP, respectively, of which the SNMP is the simple network management protocol, it is by the Internet engineering task force, put forward by the IETF and SNMP is a common management information protocol, it is put forward by the international organization for standardization ISO, is a kind of common management information protocol. The main components of network management system include administrator, management agent, management information database, agent service equipment, etc. The architecture of network management system is usually divided into two types: centralized and non-centralized.

At present, most of the departments in the computer network management, use the centralized and unified model of network management technology, namely the Client/Server technology, the technology cost is small, simple structure, easy operation, good experience for the user, but it has many problems, for example, in the process of computer network management, fault and screening, analysis, site number too little, is usually a site responsible for the management of multiple Internet, when the network is busy, the site of the workload is very big, will inevitably occur block and chaos, the network management efficiency is low, cannot satisfy for more in the field of management and organization and coordination. Nowadays, people have a very high demand for computer network management standards, the type of this kind of centralized and unified management technology cannot manage the more web site, may be wrong in the process of network management, thus affecting the implementation of the computer network management. Distributed, hierarchical network management model can be of different types of sites for different management technology, design, so that we can make the computer network management level and management efficiency improved significantly, make the safety and reliability of the computer network management can meet the demand. Distributed, hierarchical computer network management technology can also help enterprise decision-making management to reduce the pressure of work and working strength, improve the efficiency of network communication and transmission speed, make the stability and security of the computer network for promotion, strengthen the effective utilization of network resources.

With the development of computer technology and Internet technology, the emergence of Web technology has brought great benefits to computer network management. Web-based network management technology can be divided into two types: embedded and proxy, which can be divided into three levels: agent layer, service layer and client layer. The agent layer is mainly specialized agent computer network management work; The management is mainly to build the Web server, to provide the necessary basic services for each system link; The customer layer is mainly by making a request to the service layer to obtain the corresponding service, and the main representative of the client layer is the user. At some level, mode of computer network management based on Web technology, can satisfy the Internet from a certain extent, all kinds of the different management needs of customers, is conducive to the realization of the computer network management ultimate goal.

Web - based computer network management technology has the following advantages: the cost of the technology is small. Web browser enables users to the collecting and organizing information more convenient, can save a lot of education and training costs, reduce the computer network management overall cost, promote the cost benefit maximization; The technology is highly compatible. As long as can be connected to the Internet, open a web browser, you can through the link to the site, provides instant access to various sites, sharing and use of the data on the site information, and can get the information associated with the computer network management and information; The technology is relatively independent. The technology can be run independently, and the convenience and instant management and service can be realized by using Web browser, which can promote the improvement of computer network management level and satisfy the needs of users.

CORBA is a proxy pattern based on a common object request architecture, which is managed by a standardized application system developed by OMG organizations in the world. The network management technology based on CORBA can realize the connection of program separation computation and object combination, and effectively deal with the heterogeneous work problem in the program object. The advantages of CORBA network management system are: in a separate application, it can use a variety of external language editors to support the distribution operation and interconnection sharing of application objects. CORBA can automatically collect desktop application of information resources, the transformation of an existing web application data, making it can use the network information resources, strengthen the specific application of desktop operating and custom functions, the network system state changes, the structure of network resources be extended.

With the development of Internet technology, the intelligent function of the Internet has gradually attracted attention, so the intelligent direction is also an important development direction of computer network management technology. The intelligent development of computer network management technology gradually increase to the requirement of management, computer network management personnel should not only to master professional knowledge, also has a wealth of management experience and strong strain capacity. If only rely on the network managers to manage computer network, and it can not adapt to the development of computer technology, even if the management of the operation is very skilled, the experience is very rich, he had made a mistake, will and the development of computer network management technology of intelligent can reasonable use of the function of the computer, so that the computer to realize the self adjustment, this is the development direction of computer network management technology.

Nowadays, gradually expand the application scope of network, data transfer volume is also increasing, this will reduce the network management efficiency, waste CPU time, the hierarchical development of computer network management technology can change the network management architecture, through the service can be carried out on the information of computer nodes between the layers, using the lower nodes to the layer of data transmission, it can effectively improve the efficiency of data transmission, reduce the operating requirements to management.

To sum up, in the informatization today, the network is the business, the network needs to better serve the people, so the computer network management appears particularly important. Relevant technical staff to continuously enhance the level of computer network management technology, promote the development of computer network management technology of intelligent and hierarchical, so that the computer network management level and management efficiency improved significantly, guarantee the healthy development of the computer technology.
