Theory and principle of network construction of small and medium-sized enterprises

In today's world, if any big enterprise has not built up its own network system, it will be considered: "This enterprise is too backward." And this "backward" phenomenon, although at present in China's modern enterprises are rare, but in the total number of enterprises in China more than 98% of the small and medium-sized enterprises, this phenomenon is still not uncommon. So, how to build a sound SME network? Below we start from its principle and the standard two aspects to discuss: start from the construction principle the small and medium-sized Enterprise network construction Project scale is not big. General Small and medium-sized Enterprises network construction includes: integrated wiring, network equipment, firewalls, virus protection software, such as the overall price between 5.2 million yuan. Although the scale of network construction project is not big, but the complexity of technology and the difficulty of construction is not small, the so-called "Spadger, spite". Such as: integrated wiring is more in the existing office space on the basis of the transformation, this needs to take into account the need for the original network analysis and transformation, to take care of the existing old equipment enterprises; With the in-depth application of various management software, many enterprises in the workshop also requires computer networking, in order to establish a management information system data collection points, This means that in order to comprehensively consider the complex environment of the enterprise, the difficulty of designing the construction plan is more complicated than the general wiring of the ordinary building. 1, the crux of the construction (1) the need to lock the difficulties in general small and medium-sized enterprises lack of professional, for the whole enterprise network construction needs to consider the focus of lack of grasp capacity, so often rely on system integrators to make a proposal for the enterprise, to recommend the corresponding products. However, because of the integration of the purpose of their own, as well as different types of products different configuration of many, for enterprises to select products to increase the difficulty. Like a person who does not know computer to computer city to install computers, what to buy all by business recommendations, businesses and the choice of computer accessories brand is also very much. The difference is: The computer information can be found everywhere, and the enterprise network construction related to various types of equipment including: server, switching equipment, network cable and related auxiliary material selection is relatively complex. Finally, what brand and model products to be adopted must take into account the actual needs of the enterprise. (2) The tender will not be able to attract benefits generally speaking, tender can bring lower prices for enterprises, however, many enterprises in the selection of tenders, can only make a relatively simple basic requirements, in the tender documents can not determine the required product specific specifications, models and quantities, for the integration of bids left a great design loopholes. Cause the integrator according to the specific configuration specifications provided by themselves, the same product of different configuration will cause a great price gap, so the lowest price does not mean that the good performance of the price ratio, this situation will not be able to invite tenders to bring real benefits to the enterprise. (3) Program change frequent integrators will not invest too much in the early stage of contract signing, early research is often relatively simple, the preliminary design scheme is relatively simple, and can not directly guide the project construction. Enterprises and integrators in accordance with this simple scheme signed after the contract, in the late implementation of the project, often the original design will not go through, must change the design. Limited experience in enterprise construction, the initiative of design change is basically mastered in the hands of system integrators, and the result of change often leads to the increase of engineering cost. (4) Lack of professional construction management experience due to the Professional staff and project management experience, in the specific construction process control and management rely mainly on the control and management of integrators, enterprises can only control the entry of equipment, for the actual construction and use of the consumption is difficult to accurately control. This may cause integrators to make a false statement about the number of equipment in the contract negotiation stage, and cut corners in the construction to gain profits. 2, the analysis of the problem above is due to the existing process structure problems. And the whole project is the game between the enterprise and the integrator, lack of coordination in the structure, because the small and medium-sized enterprises are lack of professionals, but also lack of information market and product in-depth understanding of the project at the initial stage of their own needs difficult to clear, had to be led by the system integrators enterprise IT architecture needs analysis. System integrators often rarely consider the existing equipment and network of the enterprise for various reasons, vigorously to promote their agents to the enterprise products, in the early stage of the tender for the needs of enterprises to cater to each other, and in the implementation process, in proposing a number of change requirements, in order to reduce the difficulty of construction, shorten the construction cycle, as soon as possible, resulting in the final results of the project. At present, most enterprise network project work flow lacks two key links, one is the design, the second is the supervision. Since the initial stage of the project design is too simple, when the demand for enterprise bidding is not clear enough, the key items such as the equipment brand, model, specification and quantity can not be determined, forming an integrator bidding price in different starting line, the difference between the specific configuration leads to the huge price difference, Cannot obtain the reasonable price through the negotiation, the same reason has also caused the implementation stage project change to be big, thus has affected the whole project cost and the construction period, moreover in the construction process lacks the supervision, causes the enterprise project construction process to be difficult to control. 3, the Construction method ideal integration project structure, the enterprise should from the project participant's role then becomes the project supervision and the management, uses the structural checks and balances to realize to the project control. The design and supervision roles are added to the structure. The work of each role at a glance, here needs to be explained: The design role of the majority of the work can be performed by integrators, enterprises do not need to act as "Soma" bole, as long as the use of "horse racing" method, invited more than integrators for the enterprise to provide initial design, of course, the The work of revising and forming the tender documents can be entrusted to the expert or consultant to complete, and on this basis form the professional bidding documents, the brand, model, specification and quantity of all equipment are clarified in the bidding documents, so as to ensure that the bidding integrator is bidding on the same equipment, so that the enterprise needn't bargain The bidding system can reduce the price of the equipment automatically, and avoid the unnecessary loss caused by the integrator's deliberate blurring of the product configuration. The supervisor will assume the above work in this link. The introduction of engineering supervision system, enterprises can entrust a professional third-party supervision agencies, the whole process of the project, including industrialProcess contract, quality, progress, funds to carry out effective control and supervision and management, so that the entire construction of the project under strict monitoring to reduce the risk of project construction, control the construction funds, to ensure the project progress and quality. For an information construction project, the sooner the supervision work is carried out, the more advantageous to analyze and summarize the key elements of Enterprise informatization, the more favorable to correct the deficiencies of the prophase planning, the more advantageous to establish the standardized and standardized project management system, so as to ensure the smooth progress of the project construction. The rules and regulations are very important network construction, but also someone to manage, many enterprises think everything is no worries. If the network manager at this time to upgrade or add some network security equipment, they will be dismissive, do not pay attention to. Frankly speaking, this is a common problem of small and medium-sized enterprises in China, because they have limited capital budget, so basically only pay attention to the direct benefit of investment projects, for the network security This can not see the real feedback of the money investment way generally show a positive attitude. In addition, business operators on security issues often have a lucky mentality, thinking that there is a special management staff OK. However, their company's network management is often in order to cope with a variety of viruses and constantly busy, but also beware of hackers malicious attacks, although the computer has installed a lot of forms of anti-virus software, firewalls, but always so vulnerable, more embarrassing is, Network management in the face of the company's employees constantly complaining about the internet when the intermittent, suddenly up and down, but it seems powerless. We all need to be clear, with the rapid popularization of the Internet, the global network of computer viruses, operating system vulnerabilities, spam and other Internet security issues have emerged, you do not see, gray pigeons, panda incense and other kinds of virus aggression and hackers on the corporate network of malicious attacks, Leaking corporate information and other issues to the enterprise headaches. In this turbulent network environment, hacker attacks are constantly being updated, but security tools are being updated too slowly, and most situations require human involvement to discover previously unknown security issues, making them too slow to respond to emerging security issues, so hackers can always find vulnerabilities to attack, Really can be described as a network of rivers and lakes, everywhere hidden murderous, a little careless will recruit. At present, although the Internet environment for the security of the enterprise network put forward higher requirements, but the enterprise's network security is a system engineering, cannot rely on the firewall and so on individual systems, but needs to consider the system security demand comprehensively, will combine the cryptography technology and so on many kinds of security technology, forms an efficient, general, the Safe network system. Therefore, enterprises in the formation of the network should be the attitude of the network security, to pay attention to the strategy, strengthen the defense resistance ability. Enterprise information is one of the most important resources of enterprise's survival and development, its confidentiality and security are the money and life of enterprise, and the security of enterprise network is imminent. In short, in order to achieve success in the enterprise information construction, only rely on contract agreement is not enough, there are still a lot of detailed and specific work to do. Hope that enterprises adopt scientific methods to build aA satisfactory network environment, for the enterprise information construction and application lay a good foundation.
