Wireless networks reduce network traffic and save costs

This article describes in detail how to set up wireless networks to reduce network traffic? This article will give you a detailed explanation.

How can we reduce the cost of network traffic while ensuring the network speed? This is an urgent problem for many enterprises, especially campus networks.

CERNET has abundant academic resources and comprehensive Internet information. However, CERNET charges fees for its subordinate organizations to access Internet Resources Based on Traffic (more expensive overseas traffic ), as the network traffic of schools increases, the cost increases.

Many schools use the Cache technology to reduce traffic through Proxy servers. This is a good way to make full use of resources. However, in order to save network costs, more schools shield a considerable number of IP addresses and only allow access to some sites. This will undoubtedly cause a lot of inconvenience to fully enjoy network resources. If you choose to use the ADSL shunting technology, you can reduce network traffic and save costs while ensuring the network speed.

Wireless Network Solution

In terms of ADSL, the current ADSL access mode provides two types of terminals: Internet cafe users and home users. This solution uses the ADSL home access method (any method can be used for schools) as an example to enable the LAN to access the Internet through the Proxy server. In order to reduce the conflict domain and no impact on the speed, we connect the Proxy server to a port of the switch.

Server hardware requirements: CPU: P Ⅲ 1 GHz or K71.2GHz (or higher) (for more users and faster responses to multiple users, we recommend that you use multiple CPU servers ), memory 1 GB (or above ). Dual-NIC: one of the two IP addresses is connected to the Internet (which is automatically allocated by the Telecommunications Bureau in ADSL), and the other with the IP address of the LAN is connected to the Intranet.

Server software requirements: the server Proxy software can use Microsoft's Proxy, or SupperProxy or CCProxy. The setting method is relatively simple. The latter two are recommended, and the latter two can be monitored for billing, only necessary ports such as 8080, 21, and 1080 are blocked. The system software can be Windows2000, WindowsNT, or Windows XP.

Wireless Network advantages

1. It not only saves IP resources, but also uses the Cache Technology on the Proxy server, so that resources accessed by computers on each campus network are stored on the hard disk of the Proxy server, in the future, machines can access the same resources directly from the Proxy server, which can reduce traffic, increase network speed, and make full use of resources.

2. Log diary: In addition to online monitoring, the website accessed by the client can observe the activity of the current user.

3. This method provides high security for the campus network, and the Proxy server can also act as a firewall.

4. Some professional Proxy software can also be used to bind IP/Mac addresses. If the IP address does not correspond to the MAC address, the Proxy server rejects access to network resources and limits users to modify their own IP addresses.

This solution can solve all current TCP/IP-based network connection methods and allow Internet access through Modem, ISDN, ADSL, DDN, VDSL, and leased line.
