How does a router limit the speed of a LAN, how does the LAN allocate network bandwidth, and Control LAN traffic?

How does a router limit the speed of a LAN, how does the LAN allocate network bandwidth, and Control LAN traffic?

The following two methods can be used to limit the network speed of a computer and prevent the network speed of a LAN:
1. Methods of limiting others' network speeds, controlling the network speeds of other computers, and limiting lan network traffic through Routers
The specific method is as follows:
1. Enter the correct account password
Many vrouters now have built-in wireless bandwidth control functions. TP-link and even vrouters of less than 100 have these functions. First, enter the IP address of the wireless router in the address bar of the browser. The default IP address is 192.168.1.1. Then, enter the user name and password of the router to log on to the router. The default account and password are included in the manual, many vrouters use the default account and password.
2. Enable IP bandwidth control
Find the IP bandwidth control function in the vro settings menu. In the example of a TP wireless router, you must check "enable IP bandwidth control" to make it effective. Some wireless routers need to restart the router to take effect after IP control is enabled. Please carefully fill in the bandwidth type and maximum bandwidth, otherwise it will be easy to "speed up", that is, 4 M bandwidth may reach 2 m. As shown in:

Figure: vro limits upstream bandwidth and downstream bandwidth

3. Select different IP Control Rules
Select an IP control mode, such as limiting the maximum bandwidth and retaining the minimum bandwidth. You can set it to "limiting the maximum bandwidth" to limit the network speed and download speed. You can set it to "retain the minimum bandwidth" to ensure basic requirements such as Browsing webpages.
Each dormitory in the school uses a line to access the Internet. If someone is downloading it, the network speed becomes slow, and others will be stuck playing games. Is there any way to limit the network speed of others, to limit the download speed. Of course, this is acceptable. Next I will teach you how to limit others' network speeds to limit others' download speeds.
4. Set a fixed IP address for all computers
In the IP address segment, enter the IP address of the computer you want to control. Enter the IP address segment here, that is, enter an IP address range. If there is only one computer, set the starting IP address to the same. We recommend that you set a fixed IP address for all computers in the network, or assign a relatively fixed IP address to the vro Based on the MAC address.
5. Use the vro network isolation Function
To prevent computer viruses, or prevent other users from using software such as P2P Terminator, if the router has the anti-ARP function, enable it. A vro that is relatively expensive has the network isolation function. If yes, you can set the computer to a different VLAN for convenient management. At the same time, we recommend that you use the firmware with the built-in bandwidth control script if the vro can be used for tomato refreshing.
If a wireless router is old and cannot use bandwidth control or QOS to limit the speed of others' network, the download speed can only be limited by magic shield.
2. Implemented through dedicated LAN traffic monitoring software, lan network speed monitoring software, and LAN bandwidth allocation Software
By setting a vro to limit the speed of the LAN, you can control the speed of the LAN to a certain extent. However, because routers use a one-size-fits-all approach to limit the speed of the LAN network, they do not consider the specific use of LAN bandwidth (such as staff thunder downloads, normal OA Systems, ERP systems, and even video conferencing systems ). bandwidth used ), therefore, it is easy to control the bandwidth required by the normal operation of the enterprise, which is not conducive to achieving precise and targeted network bandwidth restrictions, and may even affect normal network bandwidth usage. Therefore, for enterprise Lan, you can consider using professional network bandwidth limit software.

For example, you can deploy a "jusheng network management" (: http://www.grabsun.com/soft.html) software, can restrict thunder download, prohibit PPS audio and video, prohibit PPLIVE, prohibit QQ live broadcast and other network applications irrelevant to work, the normal network bandwidth of enterprises is not limited to achieve better speed control. Of course, you can also display and control the bandwidth, traffic, and network speed of each computer on the LAN in real time through the jusheng network management. As shown in:

Figure 1: network management software prohibits thunder from downloading, shielding network videos, and disabling online videos

Figure 2: Lan speed limiting software limits computer bandwidth and controls LAN speed

In short, no matter whether it is through a router or through a dedicated lan network management software, lan speed limit software can be achieved to limit the bandwidth traffic occupied by LAN computers, but the bandwidth limit of the router is relatively fixed, it cannot flexibly meet the bandwidth requirements of LAN computers in real time and under specific circumstances. On the one hand, through network management software, P2P software can be prohibited from uploading and downloading, so as to prevent P2P software from speeding up the network, on the other hand, we can also implement a bandwidth QOS mechanism for specific bandwidth needs to ensure that key lan network applications, such as VPN and video conferencing, need to occupy the network bandwidth, this can better meet the needs of precise network bandwidth allocation and management.
