Learn about bandwidth related concepts
Bandwidth definition and operating principle
Bandwidth, also known as Bandwidth, is used to transmit available data in 1 second. This can also be understood as the data transfer rate of a transmission line .
Bandwidth describes the maximum amount of data that a visitor can download or post between websites on a computer in a given time.
Bandwidth is measured in bits per second (bps) . On today’s computers, bandwidth speeds up to millions of bits per second (Mbps) or even billions of bits per second (Gbps).
What is broadband?
Broadband is a special data transmission line capable of transmitting multiple signals and lines at the same time. There are many different types of transmission lines such as optical fiber, coaxial cable, twisted pair cable or radio.
Broadband is used to refer to any high-speed, fast Internet connection with a seamless connection.
What is Bandwidth Limit?
Bandwidth limit is known as a function to reduce the download / upload activity of users while accessing the network, to ensure stable network quality.
The function of Bandwidth limit reduces overload during network transmission, avoids disconnection, network lag, slowness,… The goal of Bandwidth limit is to make the network connection work at its best.
What is Unlimited Bandwidth?
Many users choose a bandwidth service that does not limit the speed and capacity of website access. The service allows users to quickly access and manipulate multiple Tabs at the same time , even if the capacity spikes, the transmission will work stably.
Unlimited bandwidth can be understood as broadband, within the service provider’s storage range. If you choose this unlimited bandwidth, you don’t need to worry about the transmission line, but you need to care about the purpose of use to choose a rather high-cost package for this service.
Types of computer network bandwidth
According to the scope of use
- Bandwidth in the country: Used to interact and exchange with servers in the same country. The type of inbound bandwidth suitable for you to use in the local network.
- International Bandwidth: Often used to exchange information about servers with many different countries. In case the international cable is broken, the access to international websites will be interrupted or you can still access but the speed is slow.
According to usage capacity
- Bandwidth is committed: Bandwidth is provided with a certain capacity for users to experience, when using up the capacity, users have to pay an additional fee to continue using.
- Shared Bandwidth: Use the server to share different information to overcome the situation of the server being frozen and laggy.
- Private Bandwidth: Need to pay for the Bandwidth that you want to use and not share with others.
Bandwidth measurement unit
Bandwidth is measured in bits per second and is represented by the symbol bps. Currently, the unit of bandwidth is quite large, so it is measured in units such as: Megabit/sec (Mbps), Gigabit/sec (Gbps) or Terabit/sec (Tbps).
There are several ways to convert bandwidth units as follows:
- Kilobit = 1,000 bits.
- Megabit = 1,000 kilo = 1,000,000 bits.
- Gigabit = 1,000 mega = 1,000,000,000 bits.
- Terabit = 1,000 giga = 1,000,000,000,000 bits.
Besides, after the Terabit unit, there are also Petabit, Extabit, Zettabit and Yottabit units, each of which is 10 times more than the previous unit.
Bandwidth measurement method
All carriers offering paid bandwidth services will provide the promised full Internet service (ISP).
If your family is on an Internet service plan and wants to check how much of your home’s bandwidth is working, you should use the DSLReports tool. Using this tool you can check if the connection level is correct with the ISP service pack.
For companies and businesses, you should use the Test TCP (TTCP) utility, PRTG Network Monitor.
- The TTCP utility is capable of measuring IP network throughputs between two servers. In which there is 1 server on the sender side, 1 server on the receiver side, then each server will display the amount of bytes transferred and the time used.
- The PRTG utility helps you to have graph information, graphical interface in a vivid, clear way and tend to use bandwidth over a period of time. Besides, PRTG also has the ability to measure traffic between interfaces.
You can refer to and use 5 more popular bandwidth measurement software: LAN Speed Test, Real Network Monitor, NetStress, NetIO-GUI.
How to avoid bandwidth squeeze
To avoid bandwidth squeeze, you can use the free monthly Glasnost tool . The situation of bandwidth squeeze usually occurs at the end of the month when the network connection suddenly becomes weak, then it is likely that the network operator will reduce the regulation.
Alternatively, you can use a virtual private network (VPN – Virtual Private Network). When using VPN data packets will be encrypted and difficult to identify. As a result, the ISP cannot see which website you are visiting and they cannot take measures to squeeze your bandwidth.
How to fix bandwidth lag
To fix bandwidth lag, you first need to find the cause and fix it. Some causes such as: AAG optical cable is broken, due to overload of users, faulty servers, modem devices, too many viruses, provided by network operators, …
Then you can find a specific fix for each cause. For example: If it’s the carrier, you should contact the provider directly to understand the situation. If the modem is faulty or the virus is too much, please bring the device to a professional repair center right away so they can best support you,…
Difference between Internet speed and Bandwidth
Bandwidth and Internet speed are two different but complementary aspects:
- Bandwidth is known data (data) is downloaded or uploaded from your computer to websites on the network.
- Internet speed or transmission speed is how fast or slow data is transmitted.
Your service provider (ISP) will often have different bandwidth limits for you to download or upload. Usually, users use more download bandwidth than upload bandwidth because most users download data from the Internet.

In conclusion, bandwidth refers to the rate at which data can be transmitted over a network connection. It is an essential aspect of modern communication and plays a critical role in determining the speed and efficiency of data transfer. Bandwidth squeezing occurs when the available bandwidth is limited due to factors like high network traffic or hardware constraints. On the other hand, bandwidth delay is characterized by the latency or delay experienced in data transmission.
To fix bandwidth squeeze, several strategies can be implemented. Upgrading network infrastructure, such as replacing outdated routers or switches, can help increase the overall available bandwidth. Optimizing network configurations and ensuring efficient bandwidth utilization can also alleviate squeeze. Implementing Quality of Service (QoS) mechanisms to prioritize critical network traffic and limit less important traffic can help optimize bandwidth usage.
Bandwidth delay, on the other hand, can be addressed through various means. Improving network latency involves minimizing the physical distance between network endpoints, enhancing network routing efficiency, and employing techniques like traffic shaping to reduce delays. Implementing content delivery networks (CDNs) can also mitigate bandwidth delay by caching content closer to the end-users.
In summary, addressing bandwidth squeeze and delay requires a combination of upgrading network infrastructure, optimizing network configurations, implementing QoS mechanisms, and utilizing technologies like CDNs. By taking these measures, organizations and individuals can enhance their network performance, ensuring a smooth and efficient data transfer experience.
