When determining the capacity of a wired or wireless network, networking experts frequently discuss two transmission characteristics that are equally crucial. Uninformed people frequently use the term “bandwidth” without understanding what it actually means. Bandwidth is somewhat related to the Internet speed. Theoretically, bandwidth is the capacity of data transmission over a specific time period. It is concerned with how information is changed in some way. Another term that refers to Internet speed is throughput, which is concerned with communication between two entities.
Both terms are frequently confused with one another but may be used interchangeably depending on the situation, so how are they related, how do they differ, and are they the same? Throughput and bandwidth are rate metrics that are used to gauge network performance. While throughput refers to a measured value, bandwidth primarily refers to a theoretical peak value. The bandwidth and throughput are equal in a situation where the speed of the interfaces and the communications medium are both the same and the sender sends continuously. To comprehend how the two terms are used to measure network speed, we look at how they differ.
What is bandwidth?
The amount of data that can move across a network, from a source to a destination, in a specific amount of time is measured by bandwidth. Throughput refers to the actual performance of a network, whereas bandwidth refers to the maximum potential or capacity of a network. Bandwidth measures the speed at which a network could successfully transport data packets to recipients rather than the actual rate at which packets arrive at a recipient. Bits per second (bit/s or bps), megabits per second (Mbps), or gigabits per second (Gbps) are frequently used as the unit of measurement for this metric.
When a network is operating at its best, its bandwidth represents the maximum throughput that it is capable of supporting. A network with more bandwidth can send and deliver more data to more devices at once. Because of this, a large bandwidth could provide users with advantages like fast internet and quick downloads. Some networks have wide bandwidth data transmission capabilities because they are broadband. They have faster internet connections than traditional analog services and can transport a variety of signals and types of traffic using a variety of technologies.
What is throughput?
The amount of data that moves across a network over time, from a source to a destination, is known as throughput, also known as data transfer rate. Specifically, it is the frequency of successfully reaching a recipient with data packets or messages. Bits per second (bit/s or bps) or data packets per second (p/s or pps) are frequently used as the unit of measurement for this metric. Because it can help to identify the reasons for a bad or slow connection, measuring throughput is a way to evaluate, troubleshoot, and improve network performance.
Network users want to receive high-quality responses as soon as possible after making requests, such as visiting a website, using an application, placing a call, or downloading a file. The use of efficient, fast networks enables workers to complete tasks with concentration and effectiveness. A network with high throughput transmits a lot of data per second, responds quickly to user requests, and performs well in general. A network with low throughput cannot deliver many bits of data per second. It denotes subpar network performance and might be caused by high levels of jitter, packet loss, and latency.
How to optimize throughput
Here are three steps for how to optimize your throughput:
1. Collect data
Gathering data is the first step in optimizing many different processes. Utilize software tools to track your networks’ throughput over time. You can also see if there are any periods of time when your throughput is particularly slow. Having this knowledge gives you a sense of how well your network is currently performing and enables you to come up with practical ways to enhance the functionality and design of your network.
2. Identify issues
When evaluating your throughput rates, seek out the root causes. Here are some possibilities:
Network latency is the amount of time it takes a network to send packets from sources to destinations over long distances. You can calculate this as a one-way data transfer time or a round-trip time. A high rate of latency indicates that data transmission through your network is slow. This may result in lengthy wait times for responses after users submit requests. Ideal latency levels result in highly satisfied users. Reducing latency is key to optimizing your throughput.
Data packets that are lost never make it to their intended location. Programs that rely on real-time packet processing, such as video, audio, and gaming applications, frequently experience this problem. For instance, packet loss may result in a voice over internet protocol (VoIP) system’s audio skipping. It causes sluggish service, connection problems, and sometimes even a complete loss of network connectivity. The causes of packet loss include congestion and software bugs.
Jitter describes delays in data packet transmission across networks, which are typically brought on by traffic or route changes. Users experiencing lag or glitches when accessing applications as a result Jitter can interfere with VoIP calls, making it difficult to hear and speak clearly.
3. Address the issues
Network bottlenecks are one of the most prevalent reasons for high latency. This is a reference to traffic congestion, which occurs when too many users attempt to access a network at once. This may occur frequently in offices after lunch when workers all return to their jobs at once. If numerous users are attempting to download files or are using complicated applications, the network speed may even be slower. You can minimize lags by addressing these bottlenecks directly.
To keep up with high traffic volumes, consider upgrading your routers or switches. Alternatively, you could lower the number of nodes the network uses to make packets travel farther distances. Data typically takes longer to reach its destination the more network devices it must pass through. Due to the fact that each device must copy data from one incoming port to another, outgoing port, a slight delay is introduced by each one. You might enable data to reach its destination faster by removing some of these devices.
Here are some additional strategies to lower latency and address various throughput problems:
Throughput vs. bandwidth
Your network and data transmission systems’ throughput and bandwidth are crucial elements. Here are the differences between the concepts:
Purpose
Data throughput and network capacity are measured by bandwidth and throughput, respectively. Imagine water traveling through a tunnel. Throughput is comparable to the amount of water moving through the tunnel each second. The width of the tunnel is like bandwidth. More water could pass through the tunnel or more data could cross a network with a wider tunnel or higher bandwidth, respectively. The effects of a slow water stream and leaks could still be felt in a wider tunnel, just as a higher bandwidth could encounter transmission delays and packet losses.
Relation to actual data transmission
While throughput and bandwidth both measure in bits per second, throughput is a useful metric that measures actual packet delivery. Contrarily, bandwidth is a theoretical metric that assesses the possibility of packet delivery.
Consider moving some soil to a garden so you can plant it. Your bag can hold up to 10 pounds of soil. This is like the bandwidth, the bags capacity. However, you only need to transport 5 pounds of soil to the garden site. This is the throughput, or the actual volume you delivered. The throughput is equal to your bandwidth if you fill the bag to the brim and transport 10 pounds of soil. Using a larger, 15-pound bag reduces the bandwidth to 15
Relation to data transmission speed
Speed in mathematics refers to the amount of distance an object can cover in a certain amount of time. The distance that data travels across a network in a second appears to be a logical measure of data transmission speed. However, IT experts frequently employ the word “speed” in a variety of contexts. Many people equate “speed” with “throughput” or “data transfer rate.” There is also the idea of “latency,” which describes how long it takes for a data packet to travel from a source to a destination.
A high throughput indicates a fast network because it indicates that users are getting lots of data every second. A high bandwidth network is made possible by the ability to transfer large amounts of data quickly. To better understand the subtle differences between all of these related concepts, read the following explanations:
How to optimize bandwidth
Although throughput and bandwidth have a lot in common, concentrating your efforts on improving each in particular can help you create long-lasting improvements to your network systems. To determine if you have a bandwidth large enough to handle your business needs, you can use software and data monitoring. If not, here are some steps for solving bandwidth issues:
1. Adjust your quality of service settings
You can give your router instructions regarding quality of service settings. Ensure that your network prioritizes the most crucial types of data and traffic by adjusting these. This makes it possible for bandwidth-intensive applications to operate effectively.
2. Consider using cloud-based applications
Consider using cloud-based software to manage large amounts of data. By outsourcing traffic to outside businesses, you can relieve network stress and boost speed and efficiency. You may also gain other benefits, such as data security.
3. Eliminate nonessential traffic
Blocking particular traffic or websites, like video applications and streaming services, during working hours is an option. These programs can use a lot of bandwidth, which leaves little room for crucial software. You can encourage staff to use bandwidth for crucial business operations in this way.
4. Organize the timing of your backups and updates
Backups, updates, and similar tasks take up a lot of bandwidth, which could cause the network to perform slowly or even shut down some network functions. It’s crucial to carry out these software maintenance tasks outside of normal business hours. Employees can then take advantage of the applications’ full capabilities when they need them for work.
Ways to measure throughput and bandwidth

Bandwidth vs. Throughput
FAQ
Why is throughput less than bandwidth?
More Information About Throughput Throughput can only send as much as the bandwidth permits, and that amount is typically lower. The throughput can be decreased by elements such as latency (delays), jitter (irregularities in the signal), and error rate (actual errors made during transmission).
Is bandwidth greater than throughput?
To put it another way, throughput tells you how many packets are actually being successfully transferred while bandwidth gives you a theoretical measurement of the number of packets that can theoretically be transferred. As a result, throughput is a more significant indicator of network performance than bandwidth.
What is throughput in a network?
Network throughput in data transmission is the amount of data successfully transferred from one location to another in a predetermined amount of time. It is typically measured in bits per second (bps), such as megabits per second (Mbps) or gigabits per second (Gbps).
What is the difference between the terms bandwidth and throughput Cisco?
The amount of data that can fit through a network or link depends on its bandwidth. The actual amount of data that can be transferred through a network is called throughput.
