Traffic limit! How does a Broadband Router achieve simultaneous Internet access for multiple users?

How does a Broadband Router limit traffic and allow multiple users to access the Internet at the same time? Next we will give a comprehensive explanation of this problem, so that you can have a deeper understanding of the Broadband Router. Many users are using multi-host or multi-user broadband routers to share the Internet, saving both costs and troubles. For example, sometimes some users are downloading BT, and other users want to play a legend, they may not be able to play well, because there is no speed limit for downloading BT, most or even all of the network bandwidth is swallowed up.

Bandwidth Router Traffic limit

P2P download is like a locust, and the bandwidth to which to fly is tight. P2P downloads usually allow 10% of users to occupy 90% of the bandwidth resources, as well as the processing capabilities of various switches and broadband routers, resulting in network congestion. However, whether or not a Broadband Router can effectively restrict this form has become one of its important capabilities. The first attempt was to use port sealing on the Broadband Router. However, with the upgrade of the BT client software, you can modify the application port at will, therefore, the final result of this method is not ideal.

Traffic control is in the ascendant

So the more popular method is traffic control. Currently, many high-end and high-end broadband routers and private broadband routers have this function. The traffic control function classifies data streams based on IP addresses, protocols, ports, and other information, and controls the bandwidth of different data streams. This allows you to reserve bandwidth for specified hosts or services and limit the maximum bandwidth, limit the use of massive download software such as P2P, and achieve average bandwidth allocation. This is especially suitable for multi-user networks with Mixed Voice videos and data.

Traffic limit has become an advanced feature of many broadband routers.

If you want to restrict LAN traffic, you can choose products with such features. And this kind of product traffic limit function also has their own characteristics: such as flying fish star VOLANS-4150 + Broadband Router, will support Qos traffic control function, bandwidth sharing, bandwidth reserved, supports upstream and downstream Traffic Control for a specified number of hosts and CIDR blocks. If BT or other P2P software is enabled on a machine in the Intranet for network transmission, the machine sends out a large number of connections, which affects the connections of other users and directly paralyzes the entire network. The ranking of the number of connections provided by the flying fish star 4150 + can quickly determine which machine has the largest concurrent connection on the Intranet, and then control a host or network segment through its traffic limit. When setting, you only need to enter the maximum number of upstream and downstream requests and "save" to control the bandwidth of a computer or network segment. TP-LINK and other models are representative of this product. This Broadband Router also provides the port traffic control function. Each of its lanports sets an eight-level bandwidth limit, 128 Kbps, 256 Kbps, 512 Kbps, 1 Mbit/s, 2 Mbit/s, 4 Mbit/s, and 8 Mbit/s, respectively. Managers can allocate bandwidth to computers connected to any port as needed, this prevents users on one of the ports from occupying too much bandwidth.

In-depth understanding of traffic control

In some enterprise-level broadband routers, such functions are also widely used. For example, the CW-AFC deep Rate Control Technology Deeper RateControl launched by zhaowei electronic group), through four steps to control P2P Traffic, to ensure the efficiency of network utilization, to ensure key applications, to meet the general application, avoid blocking in the WAN Access bottleneck.

The bandwidth control function has become a must-have for high-end broadband routers.

Its core technology is to allocate bandwidth through the processing policy of the current system. The CW-AFC control policy can correspond to and the user accurately defines the bandwidth policy, for the application, the CW-AFC can define the application bandwidth allocation level, and the maximum bandwidth, minimum guaranteed bandwidth, and whether the application can be rented. This effectively ensures users' key applications and limits non-key applications such as P2P, CW-AFC can guarantee the use of most users, limit the excessive use of resources of individual users.

The specific traffic control settings are not very complex. Taking this function of TP-LINK Broadband Router as an example, it is through the IP QoS function to achieve traffic control first bound IP and MAC ). After entering the configuration page of the Broadband Router, we can see that the QoS Set interface has two parameters: "upstream bandwidth" and "downstream bandwidth, after QoS is enabled, you can set it as a real bandwidth parameter. On the IP QoS settings page, you can set the IP addresses of computers with large data traffic in the "address segment", and restrict the download bandwidth in the "upstream/downstream" mode. In addition, to ensure that the computer does not have access to the Internet due to bandwidth restrictions, the router can ensure that the "downstream bandwidth" of the two hosts can be used at least 100 Kbps.
