Bandwidth management policy improvement BT download

The emergence of BT downloading Methods puts forward higher requirements on network devices. Its brute-force bandwidth grab capability affects the normal application of the network. In shared network environments such as the resident network and enterprise network, individual users use BT to consume more bandwidth, which is detrimental to their own interests. When other users send and receive emails and search for some information, it seems that I am using a 56 K Modem to access the Internet, and online games also stop Kaka, which is really a headache. If you want to change this situation, there are some ways. This is to use the bandwidth management function of the Broadband Router device to rectify BT downloads and purify the network environment.

The author adopted the "Xin Xiang" Broadband Router (NuR9058), and made two bandwidth management settings: "WAN port bandwidth allocation" and "intranet IP speed limit ", A careful test proves that this method is indeed effective.

"Xin Xiang" NuR9058 is a high-end product with rich functions. Its many functions are very practical, and the software configuration is also very flexible. Here we only use the bandwidth management part of its QoS mechanism for testing.

Test environment: One vro with broadband access provided by NuR9058,

1 mbps bandwidth ADSL access,

Download tool: 1.9310 audio and video conveyor belt threads)

Test 1: WAN port Bandwidth Allocation

Because NuR9058 provides multiple WAN ports, you can customize each external application to effectively use each bandwidth point to avoid network congestion. The following example demonstrates the actual effect of bandwidth allocation.

Take file downloading as an example. HTTP and FTP downloading are performed before and after the configuration. Because the company's main application is to access the WEB service, it must be ensured that it is not affected by the FTP downloading of individual users, we set 70% of the bandwidth to provide the HTTP service, while the FTP service can only occupy 10% of the bandwidth, as shown in figure 1.

Figure 1 Bandwidth Allocation

Test results:

Obviously, after enabling the "WAN bandwidth control" function of NuR9058, this ensures that the main network applications are not affected by FTP downloads, even when multiple users are scrambling for bandwidth, and the speed is basically consistent with the set parameters.

Test 2: speed limit for Intranet users　

In order to prevent a single user from occupying too much network resources and affecting the overall quality of the network, the author adopted the method of Rate limiting for each Intranet IP address.

The "LAN port IP address control" option is provided in NuR9058. The corresponding configuration can be used to limit the bandwidth of a single user.

The specific settings are as follows: Limit the maximum download speed of users with an intranet IP address of 192.168.1.71 to 80 kbps.

Figure 2 Intranet IP Speed Limit

We use HTTP download and click, save) and BT download for comparison. In the download of BT, this restriction limits the user's speed to 10 kb/s. If you want to grab the bandwidth, grab the user's own!

Test results:

Here, if a reader raises an out-of-the-box question: can users bypass this restriction if they modify their own IP addresses? Don't worry, there are always ways. The magic is full of feet. In "Xin Xiang" NuR9058 provides the MAC-IP binding function, the user's IP address and his MAC address tied together, he will no longer turn out the day. It is hard to deal with attackers and adopt some strict management methods.
