1. Project overview
1.1 Project status
Made in China 2025, Industry 4.0 and Internet + in recent years, as the strategic planning of domestic enterprises, the country has successively launched the "National Intelligent Manufacturing Standard System Construction Guide" and other policies to actively promote and practice intelligent manufacturing, and the attention and attention to informatization within the enterprise is also getting higher and higher, and the IT department is no longer simply a business support department, but more as a strategic department to provide value-added services for enterprises and is valued. Under the general trend of intelligent manufacturing, the network as a transmission channel will directly affect the quality and revenue of enterprise business, so stability, security, efficiency and convenience, and emphasis on return have become the main concerns of enterprise IT construction.
As an effective way to comprehensively promote the process of social informatization, digitalization has attracted widespread attention all over the world. At a time when China is in full swing to set off a wave of digital construction, enterprises, as the main body of economic activities in the mainland, are also the micro foundation for transforming the mode of economic growth, and enterprises are constantly thinking about how to enhance the competitiveness of enterprises in a more effective way, promote the modernization and development of enterprises through enterprise informatization construction, and promote the sustainable development of enterprises.
1.2 Construction needs
With the increasing maturity of wireless technology and the demand for mobile office business based on wireless, enterprises urgently need to break the barriers between wired and wireless networks through the construction of converged networks, innovate and improve office efficiency through wired and wireless converged networks, reduce internal communication costs, improve the speed of enterprise information flow, and enhance the comprehensive strength and industry influence of enterprises.

3. Construction principles and reference specifications
3.1 Construction principles
practicability
Practicality should follow the principles of application-oriented, pragmatic, urgent use first, and gradual improvement, fully protect the existing assets, do not design flashy networks, do not design low-utilization networks, and build the lowest cost and most cost-effective WLAN on the basis of reality
safety
It must have a high degree of confidentiality mechanism, flexible and convenient permission setting and control mechanism, which has prevented all forms of illegal intrusion and leakage of confidential information.
Such as: Web, WPA, Radius and other encryption functions, QOS restriction functions, etc
Manageability
The system needs to have good network management, network monitoring, fault analysis and processing capabilities, so that the system has extremely high maintainability.
When choosing a solution, you should consider the following aspects:
Implement centralized monitoring, decentralized management, and unified allocation of resources for the network
The advanced network management platform is selected to centralize the management of the whole network equipment
The network devices you choose and the important devices connected to the network should be able to be managed remotely
When designing, it is necessary to fully consider the operation and maintenance issues and do a good job in SOP
reliability
The system must operate reliably, and the main and critical equipment should have redundancy, so that if the system fails partially, it can be restored quickly and without causing any damage.
Scalability
The system is a gradually developing application environment, in the system structure, product system, system capacity and processing capacity must have the possibility of upgrading, this expansion can not only fully protect the original resources, but also has a high cost performance.
standardization
The technology used to support international standards should not be the technology and protocol specific to a certain manufacturer, but should ensure the interoperability with other manufacturers' equipment, so as to facilitate the investment protection of the network.
Technological advancement
Adopt advanced and mature network concepts, technologies, methods and equipment, but do not blindly chase the new, the latest often have problems and cannot be solved.
Performance
When designing, it is necessary to consider sufficient backbone bandwidth, reasonable network topology, and advanced and applicable technologies, and at the same time, strive to achieve non-blocking network performance, and not make the network a bottleneck for business applications.
