Small and medium-sized enterprise networking design scheme (graduation design thesis)
Scheme 1: Windows NT(Windows 2000 Server)+ Agent +Exchange+WinRoute (or checkpoint).

The above software combination can achieve the same functions as the TL- 100 Internet function server network solution, such as packet filtering firewall, mail server, web browsing agent, Ftp service agent and so on. However, WindowsNT (or Windows2000 server) requires higher computer hardware, and the price of genuine software is also higher. More importantly, technically, the above scheme requires a fixed IP address, which means that enterprises must pay extra fees at all times. In addition, the above software also needs professional system administrators to maintain. There are countless patches for Microsoft products, so you need to "patch".

The above solutions obviously do not meet the requirements of domestic small and medium-sized enterprises for the "cost performance" and maintenance cost of informatization.

Option 2 Windows98(WindowsNT)+Wingate

This scheme can realize some functions of Web proxy and packet filtering. In addition, the new version of Wingate also provides network address translation (NAT) function and firewall function. The disadvantages of this scheme are: high requirements for system hardware (if your whole system runs stably), and the overall cost of application software and operating system software is too high. Safety rules require the configuration of professionals. There is no good solution to the demand of enterprise e-mail system. In addition, some "advanced" functions require the installation of "client software". And the maintenance burden of the network system is increased.

Scheme 3 Windows98(WindowsNT)+dns2go

In this scheme, the corresponding client software is installed on the Windows operating system, which works with the DNS server of dns2go site to achieve the purpose of dynamic domain name resolution. This scheme can solve the DNS communication problem between TL- 100 Internet function server and the Internet in the one-stop INTRANET/INTERNET solution for small and medium-sized enterprises, but this scheme can only choose the user's domain name in dns2go.net. If you transfer the domain name of your own enterprise to the domain name server on dns2go for authorization resolution, the domain name server of dns2go only does domain name resolution, and does not provide other services related to the domain name (such as the problem of receiving mail when the mail server is offline). In addition, the stability of this scheme is that when the communication line is not good, the IP address of the user machine is frequently dialed to connect with the ISP, and the host domain name record of the user domain changes frequently. However, these changed data will not be the same as the data cached in other DNS servers on the Internet at any time, which will lead to the failure of Internet services that require fixed IP, such as WEB and E-Mail. (For example, when the domain name and IP address change, users on the Internet may not be able to deliver e-mail to the domain, or they may not be able to deliver e-mail to other servers that happen to use the same solution and have SMTP).

Compare the cost of one-stop intranet solution for small and medium-sized enterprises, the cost of traditional access scheme, computer hardware platform, stable industrial hardware platform, no need to buy hardware platform, about 10000 yuan, operating system based on Linux, without Windows 2000 Server( 10 user) 12, 270 yuan proxy service function HTTP, FTP and Telnet do not need to buy professional software MS proxy server 12784 yuan mail service function enterprise domain name mailbox (unlimited number of users, unlimited mailbox capacity) do not need to buy professional software Exchange(25 users) 24807 yuan WEB function provides 100Mweb space without renting web space 1. 000 yuan/year firewall function does not need to buy professional software Checkpoint 30,000 yuan, the price is high, 65,438 yuan +08,700 yuan to achieve the same function, the price is several times that of the former 908,665,438 yuan+0 yuan service and management Web and mail services, network security management, providing daily network security status, online browsing and email as required, and enterprises do not need professional maintenance of 2,800 yuan/year.

After receiving the confirmation fax and remittance voucher, we will upload your homepage to the virtual host provided by our company.

Virtual Host Scheme Virtual hosts use special software and hardware technologies to divide server hosts running on the Internet into "virtual" hosts. Each virtual host has an independent domain name and a complete Internet server (WWW, FTP, Email, etc. ) function. Virtual hosts are completely independent and can be managed by users themselves. From the outside world, each virtual host is exactly the same as an independent host. Shanghai Tianao Technology's one-stop solution provides high-quality network environment and servers for small and medium-sized/growing enterprises, and is monitored by senior network management. You can choose one of the following three options, or contact us directly to customize the service.

Type a virtual host 150M B virtual host 200M C virtual host 500M.
