Along with the development of information technology, computer network hardware equipment has got great development, and computer network connection size also got great progress, but the reliability of the computer network is still the most fundamental requirement, in order to ensure that social development and people's trust in the reliability of computer network, this article from the meaning of the computer network reliability, the influence factors of reliability, and how to improve the reliability of computer network, a brief analysis, and gives some Suggestions and strategies, hoping to bring the reliability of the computer network design workers some meaningful enlightenment.

In today's advanced informatization of the industry, network technology can play an important role. In order to ensure that the computer network does not suffer from the interference and damage of illegal information, ensure that it can operate normally in daily life, and ensure that there is no sudden network interruption, all these situations require the computer network staff and users in life to keep a rigorous observation at all times. So, the computer network reliability is the most critical and most basic target, maintain computer network operation of continuous and smooth, if suddenly appeared computer network interruption or other malfunction, repair the problem as soon as possible, do a full range of network supervision, avoid integral spin out of control or computer network paralysis. Therefore, it is of profound and significant significance for the development of the computer industry to conduct a comprehensive analysis and discussion on the reliability of computer networks, find out the causes of their reliability problems, and draw accurate results.

People are nervous about the reliability of a computer network, which involves more than just trust. Its reliability also contains the ability to effectively complete relevant tasks given by users under certain background. There are three reasons for this level of structure. First, in addition to the background of computer network, there is also the environment of computer hardware in the network environment. Second, the computer network must complete the task within the limited time, especially in today's fast-paced social life, the work efficiency requirements are increasingly stringent, minus people's working time, in the designated time to complete the task efficiently; Third, if the computer network does not complete the corresponding work within the specified time, then even such computer network efficiently completes many other work tasks, but in this aspect of the work, the computer network is also unreliable. The above three aspects are the general meaning of its reliability, in which all elements are indispensable, and only the complete elements can effectively guarantee the reliability of the computer network. In today's era of rapid development, cannot leave computer network help, therefore, to ensure its reliability is very critical and important, once the computer network reliability under threat, so the operation of many industries will be chaos, all the work is not smoothly, to paralyze the computer network, is likely to be seriously damage and enterprise economic benefits as well as China's social and economic benefits.

Now in the era of development is very rapid, under the background of times there is compelling evidence that the progress of computer network, as a result, the reliability of the computer network, the computer network designers and users of computer network, computer network workers have positive efforts to ensure that the computer network system would be able to play their own ability to work, in short, in view of the computer network system, can use network connectivity and the response time of multiple performance symbol to express, computer network system in fact there are so many internal functions, but in terms of reliability is gradually reduced. In general, under the guarantee of network connectivity, the computer network system can basically meet the needs of users.

The network topology affects the reliability of the computer network. Computer network has a structure called on physical connection topology, each terminal interface is composed of computer network in series, a total of six kind of computer network topology structure, ring topology, the general linear topology and topological type mixing these three type of topology is all three of them, are the most basic, any one is in certain ways affect the reliability of the computer network. The corresponding solutions and analysis methods are developed for the corresponding computer network problems.

Must raise the computer network equipment input, USES the modernized computer network equipment. The improvement of equipment is the fundamental guarantee for the operation of computer network. To ensure a highly reliable computer network, the practical method of relatively rapid and efficient is to increase the input amount of computer network equipment, thus promoting the hardware and software equipment in an efficient computer network system. Nowadays, the development of science and technology is faster and faster, and the update of computer network system with high efficiency and high security on hardware equipment is faster and faster. As the connection between the lines and hubs is transferred to the terminals of the customers, the technical production of the computer network is gradually improved, and the performance of the network products is more prominent. With the formation of more and more large-scale production, as the price is reduced, it is more and more possible to promote a wider range of updates.

Increase the use of hierarchical computer network construction. Performance on the separation of rules apply to the inner part of the computer network construction, the possibility of using the largest major performance plate to ensure independence, after use channels connected, joining a part of the module's performance problems, will therefore in the way the whole operation of computer network, such not only ensure the normal operation of the computer network, also reduced the computer network WeiXiuZhe some troubleshooting time. Computer network of any one module has irreplaceable function and role, and rely on different levels for different combinations of the function is different also, produced as a result, it presented the whole computer network all functions, because such a design can ensure the role of the various components of a computer network, let the computer network as a whole to get effective guarantee.

Pay more attention to promoting the overall design of computer networks. The complete system of computer network construction and the design of the whole layer construction establish the overall design of computer network. First, real equipment with a formal computer network can be embodied in the computer network system. Secondly, the complete system of computer network construction and the whole hierarchy construction are also important parts of the computer network system. Even if the general computer network will not be able to obtain a form of computer network system in construction and the overall hierarchical structure, but also should pay attention to and attention to a point, computer network structure of the whole system and the overall hierarchical structure, and computer network real equipments to ensure that the actual operation of the computer network, the intrinsic relationships between two parts is quite close. So, want to clearly understand, want to advance to accurately calculate the computer network system in construction and hierarchical structure, and develop appropriate design, at the same time, improve without computer network in the form of structure reliability, makes the real equipment computer network to show the effect of itself, can create the human nature of computer network system as a whole.

Make sure it's economically viable. When running the reliability analysis of the computer network, when ensuring the reliability of the computer network, it is also necessary to have a comprehensive consideration of its operation cost. It is better to make a special design according to different rules and standards, so as to decide the best design scheme. This will not only improve the reliability of the computer network, but also control the cost of the computer network operation within the appropriate range. At the same time, the computer network maintenance, network update, network use period, network upgrade and other aspects of deliberate, in order to ensure the normal operation of computer network while minimizing the cost.

Nowadays, computer network technology is the mainstream technology in the field of technology development, which has brought a significant effect on the improvement of science and technology. China is the world's largest developing country, in the field of computer network technology bear the important responsibility, science and technology has obtained the promotion, slowly advanced computer network technology applied in social production and the national economy of China, so, find a way to keep the computer network reliability and strategies are necessary. Use all kinds of improve the reliability of the computer network, a plan of computer network layout, increase the overall study of the computer network design, and use all kinds of design method of a bit, rule out the failure of computer network, ensure that the computer network security, maintain the operation of the computer network is smooth, to improve our advanced computer network technology has a role in promoting, the development of China's electronic information industry and promote play a key role, is a powerful comprehensive national construction with China, to accelerate the process of Chinese social modernization.
