There is no unified statement at home and abroad about the concept of an enterprise or a company. Generally, an enterprise is engaged in activities such as production, circulation, or service. In order to meet social needs, it operates independently, bears profits and losses, bears risks, and implements independent accounting, basic economic unit with legal personality. Enterprises can be divided into industrial enterprises, commercial enterprises, agricultural enterprises, scientific and technological enterprises, cultural enterprises or companies. Small enterprises or companies occupy a majority of all enterprise types, and the fast transmission and receipt of information has become one of the key factors for enterprise growth in recent years. Internet access and networking for small enterprises have been a hot topic in the past two years. For most small enterprises, how can we quickly set up a network to enter the information age?
I. preferred method
This is an information age. It is also true for small enterprises to grasp information first and then business opportunities. That's exactly how small enterprises with foresight have strengthened their network Informatization Construction in the past two years. Many small enterprises are networked in their offices, business, and design departments, which not only improves production efficiency, but also saves time and money. We believe that the following networking method is more suitable for more small enterprise users who have not yet established a network or need to upgrade the network.
1. Traditional star network
Traditional star network
A star network is the most widely used networking structure in Lan. It connects computer devices in the network through a hub or switch, and each node is star distributed. The transmission medium is twisted pair wires, such as common cat-5e wires and cat5e twisted pair wires. It has the characteristics of low investment and convenient mobile expansion of computers. During expansion, you only need to pull one more line from the hub or switch and other centralized devices. Its maintenance is also very easy. If a computer fails, it will not affect the connection of other computers, and the faulty computer can be removed at will. Moreover, its network transmits data fast and can be expanded to a gigabit network, it is very practical for small commercial enterprises with high data transmission speed requirements.
2. wired and wireless hybrid network
This kind of network topology is a network structure that combines the star structure mentioned above with the emerging wireless networks. This kind of topology structure can meet the needs of the expansion of networking for small enterprises, it solves the problem of deployment complexity of star networks and limits the transmission distance between single-segment transmission distances of twisted pair wires in star network transmission media by 100 meters, many high-power wireless routes can achieve several hundred meters of transmission distance outdoors, which is suitable for small production enterprises separated from office and factory ).
This network topology combines the advantages of a star network and a wireless network, and also makes up for each other's shortcomings. In addition, the investment is not high, and maintenance is very simple. It is suitable for small enterprises with limited financial resources and no professional network maintenance technicians. Of course, the key device to achieve this convenience is a wireless router.
Wired and wireless hybrid network
Generally, small enterprise users apply for only one broadband line, while the account provided by the broadband operator can only be valid for one Intranet IP address, and other Intranet IP addresses cannot log on with the same account, ISP networks will deem the second illegal user and refuse to log on to the Internet, which puts many computers in a wave-free situation. In the past, routers only target enterprise-level users. Although they can solve Internet sharing problems, SOHO users and small enterprises are unable to afford the high price. As demand increases, the Wireless Broadband Router for SOHO/individual users has been very mature and affordable after several years of development. A wireless router allows multiple computers in the enterprise, office, or home to share the Internet, provides a 10/100 M Adaptive Ethernet WAN interface, and can be connected to ADSL/Cable MODEM or Ethernet switch/router. The built-in four vswitch ports allow you to connect to four or more computers in a wired manner.
In addition, for the network security issues that small enterprises are focusing on when building their networks, the Wireless Broadband Router can also be easily competent for its security functions, it is convenient to build an environment where multiple users access the Internet at the same time in small and medium-sized enterprises, and has robust firewall security features. It can filter MAC addresses, IP addresses, URLs, domain names, and other data to implement access security policies, VPN Pass-Through services such as IPSec, PPTP, and L2TP are also supported to transmit sensitive data securely and encrypted.
In short, the Wireless AP or wireless router can take into account the Internet access problems of small enterprise networks, basic architecture problems, network security problems, and expansion problems. The popularity of wired and wireless hybrid structure networks is due to the reduction in the price of small-scale wireless routers and the simplicity of WLAN construction.
