Analysis of enhanced broadband connection performance DSL and wired broadband speed regulation devices

Bandwidth speed adjustment is a technology that improves DSL performance and wired Internet connections. When broadband technology began to become popular, domestic network enthusiasts began to experiment with Cable and DSL adjustment.

The adjustment of low-speed (dial-up) Internet access performance is often not comparable to that of normal broadband connections. Although the speed adjustment of broadband originally focused on improving the speed of surfing the Internet, it is more common to adjust specific applications, such as P2P file sharing systems and games.

Limitations of bandwidth speed adjustment

First, the bandwidth adjustment should be carried out after your network is tested and confirmed to be reliable. The speed adjustment is only to optimize performance, not to fix installation errors or basic network configuration problems.

Speed adjustment may only result in a small growth rate, but in some cases only. For example, adjustments designed to improve the performance of an online game may only benefit this program and only take effect in the initial loading. Broadband adjustment may help certain applications (such as games), but may also affect the speed of other programs (such as Web browsing ). In general, it is assumed that any performance advantage that can be obtained may be a 10-20% increase, rather than a 100-200% increase.

Finally, the speed adjustment will bring instability to the network. Depending on the device type and network service you are using, some adjustments may be incompatible, which need to be avoided.

Adjustment type of bandwidth speed

The most common bandwidth adjustment includes adjusting the parameters of different TCP/IP network protocols, typical of which are:

◆ TCP Receiving Window Size

◆ Maximum unit (MTU)

◆ Maximum segment size (MSS)

◆ TTL)

The Microsoft Windows registry contains the default values for TCP/IP parameters. You can use the registry editor or the optimized TCP tool (see below) to change some default values each time you restart your computer. Other operating systems such as Linux and Mac OS X provide alternative mechanisms to adjust TCP/IP parameters.

Another common broadband adjustment requires you to manipulate Web browser settings. For example, downloading large images can save network bandwidth, while downloading bandwidth can speed up the download of other data.

About adjusting the broadband Web acceleration device

Traditionally, the speed adjustment is applied to the network by the Administrator and can only be one component at a time. However, in recent years, application software has developed rapidly and can help us adjust and maintain it automatically.

The so-called network download accelerators are actually pre-packaged software programs that can automatically adjust the speed of computer applications. Install and run an acceleration program to automatically generate a registry, Web browser, and other settings. The more detailed the information that application software collects on your computer and on the Internet, the more detailed your interests will be guaranteed.

However, many Web accelerators are designed for dial-up networks. The following are useful tools for broadband accelerators:

◆ Network Download Accelerator

◆ Google Web Accelerator

◆ Netfury

◆ ONSPEED

Make the bandwidth adjustment take effect

Due to improper speed adjustment, computers or networks may be paralyzed. Therefore, you are skillful in testing each change. If possible, use a verified Web Acceleration Program instead of manual adjustment, and test each change one by one.

If you want to know whether the speed adjustment takes effect, you can use the Internet speed testing service. And compare the network performance before and after adjustment. In addition, you can try local file transfers, Web downloads, online games, and other commonly used applications to evaluate the effect. If there is no significant effect, undo the change without hesitation.
